A Hosta Imposter and Other Relatives.

When I moved to go to school I soon missed the outdoors in the way I had experienced it during my life. I was no longer able step outside and wander in the woods within a few steps of the home I had lived in. It was not until I moved to the island I am on now that I had time to find the wild again as it was much closer. Now I wander in the woods and along paths where wildflowers and nature is close to undisturbed. People here care a great deal about keeping it that way. I have had the chance to become re-aquainted to some plants which were beloved by our family here. The Maianthemum family offer up 2 of these loved plants and 1 other which is new to me. I a particularly fond of Maianthemum dilatatum( Wild Lily of the Valley)

Maianthemum dilatatum (Wild Lily of the Valley) is now is the same botanical family as the real Lily of the Valley(Convillaria majalis).

Maianthemum family has recently gone through several changes which are important to note: first it has expanded to include the species which were once known as Smilacina.  The other more important thing is that Maianthemum species was moved from the Lilacae (Lily)family into the Ruscaceae family which includes Convillaria(Lily of the Valley) now. It shows the close relation of Maianthemum and Convillaria.  This realignment is quite interesting botanically as it changes what we used to think of as Lilies(Lileaceae).

As a child I would pick armloads of Maianthemum racemosum (Smilacina) and give them to my mother to put in vases at home.

Around here you will most like come across Maianthemum dilatatum in the moister areas of the woodlands. I first came across it along the path that ran next to the house I lived in for many years. Not far away I found it growing with horsetail under the Rhododendron plantings at Dominion Brook Park, the contrast in textures was interesting. I was delighted to find it on my first visit to Finnerty Gardens where it is used as a lush groundcover. I now see it in many places which are shady and somewhat damp throughout the year.

This bright Rhododendron luteum is set of by the lush Maianthemum dilatatum covering the ground so completely at Finnerty Gardens.

The similarity of False Lily of theValley  to Convillaria is somewhat hard to find as the leaves are so broad and the flowers are not bell-shaped. Both plants are highly fragrant and all parts are poisonous to consume in any form. Mainathemum dilatatum is found in a large area running from Northern California along the coast through Alaska on to the Russian coast south into Korea and finally into Japan.  Maianthemum was named by Linnaeus most likely after M. canadense which was already known from samples collected in eastern North America.

The leaves of Wild Lily of the Valley (Maianthemum dilatatum) remind me very much of that of some Hosta cultivars with their overall shape and vein pattern of the leaves.

There are other members of the Maianthemum family which are more refined, the already mentioned M. canadense is a charming smaller version of dilatatum. Maianthemum stellatum grows here and was originally classed as a Smilacina which is seen in its foliage. It has few flowers and is delicate, I first came across it near Playfair Park at the top of Judge Place growing along a seep area.

Maianthemum stellatum is a delicate colonizing plant found in the woodland across northern areas on North America.

All the Maianthemum species I have mentioned here can be vigorous spreading plants and care must be taken when placing them in your garden so they do not overwhelm other weaker plants. The most agressive of these plants is M. dilatatum which creeps into gardens and provides a seemingly smothering coat of  leaves. These plants grow by creeping rhizomes(roots) which are able to branch and spread more widely. They all like rich moisture retentive soil which does not dry out completely during hot periods. These plants prefer dappled to fairly deep shade and will go prematurely dormant if they are too exposed to overly bright, dry situations.

Wild(False) Lily of the Valley (Maianthemum dilatatum) provides a strong and lush groundcover.

 Maianthemum racemosum, stellatum  and canadense are extremely hardy plants and take zone 3-8 (-40 c and f.). Maianthemum dilatatum tolerates probably -20 c (-4 f.).  M.racemosum grows to 1-1.25 m.(4 ft.) tall and easily as wide. The other species will grow no higher than 35 cm.(15 in.) tall and an indeterminant width. M. canadense is the smallest and least vigorous growing plant and could be used in more delicate places. All these plants are highly fragrant, have good autumn coloring and make good cut flowers. All these plants fit into the woodland garden and can be used for groundcover, massing  or as accents. Maianthemum racemosum is a standout plant with attractive foliage, berries and golden autumn coloring which makes it an excellent specimen for a shady garden.

Tellimas and Other Anagrams

When I was going to for Horticultural training the thing I missed the most was walking in the woods like I could do at Home. I had come from a rural area to a verge large city to go to school and going for a walk was a way to relieve tension from my studies. There was a small park at the end of my street which was undeveloped and I would visit there and find new(to me) plants which where native to the area. One plant I came across looked kind of familiar, like a Heuchera but different, as it turns out it was a close relative. Tellima grandiflora (Fringe Cups) is related to several well-known garden plants and should be seen more in gardens.

Tellima grandiflora (Fringe Cups) are found edging a shade path in Beacon Hill Park.

I always am interested in what the botanical latin name of a plant means and how it might relate to it. In the case of Tellima it turns out to be an anagram of another plant which is closely related to it: Mitella. I have found no information on why an anagram was chosen for its name. Another case I know of is for a species of cactus Lobivia which is an anagram of the country which it is found in Bolivia. Grandiflora is not at all unusual and refers to the large flowers.

The common name 'Fringe Cups' refers to the lacy petals of Tellima grandiflora flowers.

Tellima grandiflora is a plant which grows in the woodlands and dappled light of the Pacific North-west from Alaska through British Columbia, Washington, Oregon into Northern California. This is generally a plant of coastal areas and along the mountains that run just inland. They are also found in the inland wet stripe running through eastern B.C., Washington, north Idaho and Montana. Here on Vancouver Island it is a common site along roadsides and is often mixed with other plants such as Tiarellas, Sedges and Ferns.

Here at U.B.C. Botanical Gardens the Tellima grandiflora grow wild as a natural groundcover in the Asian Garden.

Tellima grandiflora comes from the Saxifragaeae which has given us many familiar garden plants such as Saxifraga, Heucheras, Tiarella and Fragaria (Strawberry). All of these species have been hybridized and are well used in the garden. Tellima grandiflora may have been hampered in its acceptance because it is a is the only species of the genus and is not represented in any other form in the world. There are records of crosses between Tiarella and Tellima being found as well as that of Tolmeia menziesii crosses but none of these have been seen as worth being developed as they have much smaller flowers than Fringe Cups and the foliage is not unique enough. Only recently has been offered a named Tellima grandiflora ‘Forest Frost’ which to me looks like it probably is mis-named and is fact a cross with a Heuchera. It will be interesting to see what comes of this new plant.

Winter coloring of Tellima grandiflora often brings out burgundy tones which fade with new growth.

Tellima grandiflora for the most part is a well-behaved garden plant. It self-sows in place that it is happy, if this is not wanted all that is needed is to remove the spent flower wands soon after they finnish blooming. It can be somewhat short-lived like many members of the Saxifragaeae family are, therefore i usually keep a few seedlings about to replenish older plants and I like how they will pop up in my pots of Hostas and amongst the hardy Geraniums. Fringe Cups make a good addition to the garden and its foliage and flowers work well in spring when other plants are slow to emerge.

This accidental combination of Meconopsis cambrica, Tellima grandiflora and Claytonia sibirica is charming and bright at the same time.

Tellima grandiflora is an easy adaptable plant to have in your garden. It like rich, humusy soil which retains moisture well during the dry months of summer. It like dappled positions and will bloom admirably in more shady situations. In overly sunny sites it often has more yellowed foliage and is smaller in its overall stature. This last winter was colder than usual and Fringe Cups came through in great form, no damage is done to the foliage and steady growth is seen in the earliest spring. These plants are typically 60 cm.(2 ft.) high and 45 cm. (18 in.) wide but may be slightly large or smaller depending on conditions. They are rated as tolerating -20c.(-4 f.) which is suspect is with much snow cover. Here the extreme cold might get to be – 15 c. (5 f.) with the wild chill added and they do not suffer.

Tellima grandiflora is incorporated into several gardens at Government House in Victoria. Here it is the Cutting Flower Garden.

Fringe Cups can be used in a variety of ways in the garden. I have seen them used as accents, mass planted, in woodland and more formal settings. They fit into fragrant gardens and ones for cut flowers as well as shade and winter gardens. They also make an excellent mass planting  and blend in well with many damp tolerant plants. their delicate flowers on tall stems have an amusing effect against very bold foliage. These plants are much better known in Europe than they are here and we should start changing that.

Oregons ‘Grape’

This is the time of year which is the most exciting in the garden. After a cold winter we wait with bated breath to see what has survived and even will thrive. I note some Rhododendrons seem to have smaller flowers and the Tulips are finally beginning to show their buds. One plant I associate with spring is Mahonia aquifolium (Oregon Grape) which is bursting forth with its bright fragrant flowers.

The Oregon Grape(Mahonia aquifolium) here is a welcome addition to this spring garden of mixed bulbs and native plants.

Oregon Grape is a shrub which is from the west coast of British Columbia south into northern California west of the Cascade Mountains where this plant is generally found as an understory plant to trees such as Douglas Fir and here Garry Oaks. Mahonia was named after Bernard McMahon (1775-1816) who is said to have been the first ‘nurseryman’ in North America, he published the first plant catalogue and the book “American Gardeners’ Calender’  He was the curator of the plants of the Lewis and Clark collection of plants.  Thomas Nuttall honored his friend by using his name as “Mahonia’  for naming a plant (Mahonia nervosa) in the collection.

The bright flowers of Mahonia aquifolium contrast nicely with wine tinted evergreen foliage.

The leaves( and leaflets) of the Oregon Grape look similar to that of common Holly (Ilex aquifolium) but are larger, thinner and take on maroon and red tints in winter cold. This past winter was colder than normal here and the red tints are very evident on many plant here. Oregon Grape are well-known to the native people here and have in the past been used for medicinal and food uses.  The roots were used to make a tonic which was used to counteract weariness, loss of appetite  and other similar maladies. the roots contain the alkaloid berberine which is found in  ‘Goldenseal’ and has anti-inflamitory and anti bacterial properties. The fruit was as mild laxative. As a food the berries were sometimes mixed with other sweeter berries to make them more palatable. The fruit is very bitter until touched by frost and then can be used for making  jelly. Another way this plant has been used is for dying items, the roots have distinctive yellow sap and the berries provide purple coloring.

Oregon Grape (Mahonia aquifolium) produced copius crops of blue fruit which are eaten by birds after it has been touched by frost to sweeten it.

Mahonia aquifolium is much used in landscapes today and is often seen as a barrier plant in parking lots where it often is neglected and abused, there are better plants for that purpose. I like to see it used in more creative ways. One of the more interesting uses I have seen is as a background planting to Hydrangeas at Finnerty Gardens in Victoria. The garden has a collection of Hydrangeas which are dormant when our lovely Oregon Grape blooms. Oregon Grape works as winter and early spring interest and then the Hydrangea will take over for the late spring into autumn with a consistent evergreen background to show it off.

Here at Finnerty Gardens the Mahonia aquifolium (Oregon Grape) will bloom while the Hydrangea shrubs are 'leafing' out in front.

Oregon Grape is an easy plant to grow if it is given the right conditions to grow in. Mahonia aquifolium likes part sun to full shade with the only exceptions in more northern areas where light is not as strong as in the south. For better flower and fruit production give it better light.  It grows best in moist, rich, well-drained soil which is more acidic than alkaline. It does poorly on thin, compacted and clay soils which stay wet and are poorly drained. Here it grows under the light shade of deciduous trees and mixed with other shrubs. It is best to place these plants where they will avoid the drying winds of winter which can do much damage to broad-leaved evergreens here. Most of the Oregon Grape I have seen here overwintered well with little damage, the added bonus was richer maroon tints to the foliage from the winter cold.

The maroon tints of the foliage of Mahonia aquifolium (Oregon Grape) were quite spectacular this spring.

Mahonia aquifolium is a slow-growing multi-stemmed shrub which over time can grow to be well over 2 m. (6 ft.) tall. With the branches generally being very ascending , this shrub tends to have a narrow profile. The plant can easily be managed by removing branches from the base. Use this shrub in your native garden or in wilder places which might be a little out of the way. The leaves are prickly so keep it away from narrow paths or tight areas where you might brush up against it. Mahonia aquifolium is well used in mass planting or a specimen. It attracts bees by providing an early source of honey when there might be little available (the flowers are honey scented as well).  It is known to hybridise with other Mahonia species and these crosses can give varied results in height and sprawling habit.

I find the variation in the flower panicles of Mahonia aquifolium (Oregon Grape) interesting, some are stumpy like this one while others are loose and open like the 2nd picture in this article.

Mahonia is a much loved plant and has been adopted as the state plant of Oregon which is found between California and Washington. It has many appealing atributes to make a good garden plant which should be seen more ofte. There are 12 Mahonia species in North America and some of these have been listed as noxious weeds, I think that there might be some confusion in listing this species there.

The Beautiful Beast.

Many plants become famous for things other than their flowers. The form and structure of a plant influences how it is used in a garden. The overall color and texture of a plant contributes much to a plants use. Some plants remind people of other things and their name reflects that. Euphorbia species cover all these bases and more. Euphorbia myrsintes(Myrtle Spurge) has wonderful color, texture and form as well as an element which can be somewhat sinister.

Myrtle Spurge(Euphorbia myrsinites) sprawls across a rock earlier this year.

Myrtle Spurge has been known from the earliest time. Theophratus (372-287 B.C.) said it looked like a kind of  ‘Tithymallos’ and called it ‘Myrtle-like’. Dioscorides described it as ‘hath leaves like to Myrsine, but greater and strong and sharp and prickly on top’. We also come to Pliny who said ‘Mytites had medicinal uses. Flower heads where harvested and dried long before they had started to swell to blossom and were used with other plants and said to heal sores in the mouth and used as an emetic. We of course do not use this plant for any type of medical or edible use today.

The chartreuse flowers of Euphorbia myrsinites contrast with the distinctive sea green foliage to produce a unique sight in the garden.

With such an ‘old’ plant we are not the least surprised to find out where Euphorbia myrsinites comes from; the Mediterranean. Euphorbia myrsinites grows naturally in a wide area from the Balearic Islands near Corsica, moves across southern Italy through Croatia, Bosnia Hercegovina and Montenegro and through Greece. From Greece it is found in Turkey and Asia Minor south and east all the way to Iran. It is found in rocky and sandy areas as well as in open areas under open forests often populated by Pine. The plant grows from near sea level into mountain slopes.

The serpentine foliage of Euphorbia myrsinites becomes grayer in the drought and heat of summer here.

All Euphorbia species have milky sap wich is released when the plant is damaged. The sap is a form of natural latex which is sticky and contains Diterpene esters which are often irritating to people who have sensitivities. Not all people react to this chemical in the same way I for years propagated many species of Euphorbia and had no trouble, I was always careful when doing cuttings and did my work in well ventilated areas and washed my hands throughly. If you have any concerns do not grow Euphorbias which include Poinsettia of Christmas, or grow them in area where they are out of the way.

A seedling Myrtle Spurge is seen growing in a crevice with native Sedum and Oregon Grape.

Euphorbia myrsinites grows in Victoria well as long as it has good drainage. The best plantings I have seen here are at Government House in the Terrace Garden which is a steep cliff area with gardens running down its face. In this garden there are many tender and exotic plants as well as those which are drought tolerant and can live in areas with little soil. Several species of Euphorbia are featured there. There is also a rough stone staircase which has plants in the cracks including todays plant. Another interesting planting is found at Glendale Gardens where these plants are displayed in the drought tolerant garden.

The rock staircase in the Terrace Gardens at Government House is a perfect place to display Euphorbia myrsinites.

Euphorbia myrsinites is easily grown in soil which is extremely well-drained and not to nutrient rich. Full sun at all times in an absolute must. These plants ideally like to sprawl on rocks or gravel or hand slightly over edges which they dry quickly from rains.  This plant has thick leaves and a thick base which is almost a caudex which helps it withstand drought conditions for several months at a time. These plants are excellent in large rockeries, containers, slopes and out of the way crevices which are hard to maintain. Creeping Spurge grows about 15-20 cm.(6-8 in.) tall and sprawls 45-60 cm. (18- 24 in.). It is rated as growing in zones 5 though 9 or tolerates temperatures down to -29 c (-20 f.) with perfect drainage and protection from winter winds.

Here the thick caudex-like rootstock is visible where this Myrtle Spurge has been pulled out slightly.

Myrtle Spurge often is not long-lived but can produce seedlings which can be moved into place. Seedlings also are easily removed if not wanted or remove the flower heads before the seed has ripened. In some areas Euphorbia myrsinites has been classified as a noxious weed for it has been able to seed and spread into unwanted areas. It can not be grown or brought into Colorado, Oregon or Washington states. It is up to us as  nursery growers and gardeners to make sure we are not causing a problem by not taking care of our plants. by removing spent flowers or disposing of seed heads we can make sure that attractive but foreign plants do not become a problem in the future.

Colors Found in Dutch Crocus Painting.

As I look out my window today I remember what it was like at this time of year; it is the middle of February and still the snow is falling and the piles of it are getting higher and higher. Back then any sunny day would make me anxious for spring to come with the brightly colored bulbs of yellow, purple, blue and even white poking through patches of bare soil. Yes I am speaking of the first flowers of this early spring here which have a big impact. The Crocus are running amuck through the city in the parks and yards and have even gone rogue in some places! I offer up to you the  group of Crocus hybrids sometimes called ‘Dutch Crocus’ to brighten your very early spring.

These Dutch Crocus Hybrids have incredibly huge flowers, yet have a delicate quality.

There are about 80 different species of Crocus with many subspecies and varieties. Of that group only about 30 species are regularly grown by collectors and us regular people.There are 2 distinct groups ones which flowers in spring and those which bloom in autumn. Of the autumn group we would be familiar with Saffron Crocus which produce Saffron for culinary uses, the spice comes from collecting the stamens from the flowers. Crocus species originate from a large area from north Africa into south-central Europe all of Italy and eastern Europe to Russia and down through former Yugoslavia and Greece, crossing through Turkey and as far east as Afghanistan and south into the Middle East Asia. .

Crocus 'Pickwick' is my favorite Dutch Crocus with its gloriously striped blossoms.

Most of us are more familiar with the spring blooming named hybrids which are commonly called Dutch Crocus. This group of Crocus have been developed over several hundred years of careful selection of the best flower qualities. ‘Dutch’ Crocus are a group of hybrids which are primarily made up of crosses made from 5 species of which the 3 predominant are C. vernus(with the largest blooms), chrysanthus(color) and biflorus.

Here Crocus have taken over a lawn at this time of year and have revert to a color which is similar to what they look in the wild.

No one really knows were these 3 species of Crocus began to hybridise as it is possible their paths crossed in the wild. Vernus is from the Pyrenees in Europe into Yugoslavia, Chrysanthus also is found in Yugoslavia Romania, Greece and into southern Turkey. From there biflorus is found in southern Greece into Turkey and as far east as northern Iran. We do know that several species of bulbs ended up being sent to Carolus Clusius at the Botanical Garden in Leiden in the mid 16th century.

 

The golden-yellow color of Dutch Crocus early in the spring is one of the gaudiest sights in the garden.

Ambrosius Bosschaert the Elder (1573-1621) specialized in painting flowers and included a golden Dutch Crocus in one of his paintings. By 1629 a yellow Crocus had made their way to England and were being written about.  By the early 1700s lists of bulbs were carefully cataloged with their prices by sellers of the product and more color forms we re becoming known.

 

 

Crocus 'Remembrance' is an old clone with one of the darkest and richest colors.

All Crocus species are generally easy to grow and adaptable to most soil types. The one thing Crocus hate is overly wet stagnant soil which causes the bulb to rot. To improve soil drainage add sharp sand.  If Crocus like where they are growing they will multiply by growing many tiny new bulbils which can be removed and replanted. Crocus should be planted at least 15cm(6 in.) apart and 5-8 cm(2-3 in.) deep in the ground. It is best to plant or replant bulbs in the fall 1-2 months before frosts come to the garden, this gives the bulbs a chance to start growing their roots firmly into the ground.

 

This is Crocus 'Snow Bunting', a cheery flower in which each petal base is bright yellow.

 

Dutch Crocus are fairly hardy and take about zone 5 (-29 c. or-20 f.) – temperatures with ease and if you give your plants so extra protection or more snow they can take even colder situations.  Crocus grow well in gardens and can be used as edging plants, accents or specimens in a winter garden. Crocus make excellent container plants and can be transferred into the garden later if you like. Another thing they can be used for is naturalizing in lawns and grassy areas, this is because they will grow and decline into dormancy before you need to do your first mowing. Here there are several parks where the plants have spread into the lawns and look spectacular at this time of the year, later people are unaware that they are walking over the areas where the bulbs have gone dormant.

 

Pacific Bulb Society have very detailed pages on many Crocus species: http://www.pacificbulbsociety.org/pbswiki/index.php/Crocus

An Odd Couple For The Iris Family.

Another grey week and another plant hunt for something special. Usually I have a list of plants in mind but right now it is hard because some of the plants I wanted to do were damaged by an unusually hard freeze which came in early November last year. At that time many of the plants were not hardened off for the winter with the damage especially seen by broad-leaved evergreens which have much browned and dead foliage now. In my wandering last week I stumbled upon two plants of the same family which are stars at this time of the year. They are the Algerian Iris (Iris unguicularis) and the Stinking or Gladwyn Iris (Iris foetidissima). They are the stars for different reasons as you will see!

Winter or Algerian Iris (Iris unguicularis) is sometimes incorrectly labeled by its old name of Iris stylosa.

The first stop we make is with the Algerian or Winter Iris with its lovely large violet blooms. It was first described by Botanist/clergyman  Jean Louis Marie Pioret (1755-1834) in his journal ‘Voyage et Barbarie’ in 1789.  He had been sent to Algeria by Louis XVI between 1785-6 to study the flora. The lovely Iris is more widespread and found in area from Algeria and Tunisia across north Africa into Turkey, Greece Crete and Malta. In the vast area it is known to live int there is some variation in color and form.

The type of Iris unguicularis I have found in Victoria seems to be the 'Algerian' form which has the largest flowers of the species.

Algerian Iris produce new leaves in late spring and through the summer. Often you can clip the old leave edges back when they get looking tattered. Iris unguicularis likes the sunniest, driest spot in the garden with the grittiest soil. At Government House in Victoria the plants are perfectly place in the terrace garden which is on a southern exposed rock-face.  The warmer and drier the summer the more blossoms will be produced.  One thing about these plants is they hate to be moved or have their roots disturbed in any way.

A just opened Algerian Iris in the late afternoon sun has delicate coloring and scent.

The Gladwyn Iris is from more northern areas from southern England, Ireland through Portugal, Spain Canary Island on to Italy and finally the island of Malta.

The Gladwyn Iris (Iris foetidissma) is more famous for its brightly colored seeds which are seen during the winter months here.

The ‘Stinking Iris has gained an unfair reputation from its name. One has to crush the leaves and the flower to obtain even a faintly unpleasant scent. Iris foetidissima is a plant which has long been with us. It blooms in the traditional Iris time of late May and June, but, the flowers are small and often hidden in the foliage. The colors range from a creamy ochre into plummy shades.

The flowers of Iris foetidissima are often hidden in the plants foliage.

The Gladwyn Iris is a plant of the woodlands, hedgerows, scrubs and cliff edges and other rocky sites. It is a plant which likes chalky and limestone  heavy locations. Gladwyn Iris can grow in the sun or dappled shade and like average soil. They like sufficient water when they are growing in the spring and then dry conditions the rest of the year.After blooming it produces larger than average seed pods which ripen through the summer and into early winter when they burst. Inside the pods are usually bright orange seeds which remain colorful throughout the winter. The other day I noticed pods recently opened and others still green and waiting to split. Just like the flowers there are other known seed colors which are sought after and they range from golden yellows to creams and white. Probably the most want of the Gladwyn Iris is Iris foetidissima ‘Variegata’ with beautifully uniform cream stripes running up the leaves.

The Variegated Gladwyn Iris (Iris foetidissma 'Variegata') is most sought after, as you see they are stunning in dappled location at Glendale Garden.

Algerian and Gladwyn Iris are about the same height 45-60cm.(12-18 in.) and width They also share the same temperature tolerance to 15 c. (5 f.) or zones 7 through 9. Both plants are drought tolerant when they have been established. They are rabbit and deer resistant but can be damaged by slugs and snails. They make excellent specimens, accents s, mass evergreen plantings and work well in containers. Both of these species are not easy to find in plant centres or garden shops, the best bet would be to find them at garden sales or from specialty Iris growers.

Now A Completely Different Type of Plant – Moss.

The are a few types of plants which can be found just about anywhere on earth. Some are grasses others are very successful annuals which have short life cycles and survive even in hostile climate even if it is for a short while. Others are extremely ancient and where some of the first types of recognizable plants that are known such as ferns. The plants I am referring to today are also among the oldest and simplest known to us. We see them in the woods, on rocks, along roadsides, in our lawns and on roofs. I am referring to a group of plants called Moss of which there are thousands of species and many variations. They all look beautiful at this time of year here in the Pacific Northwest.

a

Many Mosses co-exist peacefully close together and with other plants.

Mosses are part of a group of plants called bryophytes which also include Lichens and Hornworts. These plants are generally tiny in stature and lack vascular systems.  Mosses are made up of a single layer of cells which are usually arranged in overlapping leaves or scales and are generally a shade of green. Because Moss lacks a vascular system it has to live in an area which is damp most of the time. Without water it would not be able to sexually reproduce.

One of the most beautiful of Mosses found in this area is Oregon Beaked Moss (Kindbergia oregona).

Mosses are one of the first plants that were likely used by people from the very earliest times. Moss has been used in many ways all over the world. From the earliest times it has been used for padding for wounds, natural diapers and other padding.  It has been used to stuff mattresses, pillows and fill cracks in walls. Mosses used to heal burns and bruises has been successfully done for centuries. Some forms of moss have been powdered and turned into extracts which anti-septic and antiviral properties. Tonics an diuretics have been used for ages.

Moss is an important part of the ecosystem of the Pacific Northwest and the rainforest.

The most important group of mosses are the Sphagnum which are used for many economic products and processes. In horticulture and gardening sphagnum produces the peat which we incorporate into soil mixes because it helps to improve moisture retention(it has the ability to absorb 12 times its weight in moisture). Peat is found in areas where the moss has for many centuries grown and partly decomposed creating deep layers of pure product. It is found in northern areas of the globe. In the past it has been cut, dried and burned as fuel to warm homes.   Now we also use it for filtering and treatment of waste waters, effluent detergents, dyes and other organic substances.

Wet Rock Moss (Dichodontium pellucidum) is found on sea level cliffs and bluffs is an important soil stabilizer.

Many moss species are good indicators of soil conditions as the will survive in narrow pH conditions.  They also can indicate environmental condition such as levels of pollution. Moss create a covering to slow down erosion of nutrients by protecting underlying surfaces from excessive water run-off. It also provides protection from winds in the same way.

Fragile Fork Moss (Dicranum tauricum) is a commonly seen moss which grows on sidewalks and along paths.

here in Victoria there are many rocky outcrops covered with moss. Within these areas are miniature ecosystems often populated with several forms of moss and lichens which are slowly breaking down the rocks. The mosses do this by releasing acids which work on the rock over milleniums. Crevices develop where soil is created and other plants can come in and grow.

Here we see Pixie Lichen and Licorice Fern getting established in a thin layer of moss-soil on a rock outcrop at Playfair Park.

We take the lowly Moss for a pest, but it really is an important part of the ecology of the earth. We should be more tolerant of its existence and learn to see it as a feature in our gardens as a simple groundcover which it is. In Japan Moss plays an important role in gardens and is featured in many well known ones.

Here at Government House Moss mingles with other alpine plants to create an attractive display which has interest thoughout the year.

On the Tropaeolum Trail.

When I was small we would go for walks with our mother in the neighborhood and stop and look at the gardens, some were interesting others where more playful and some just a plain messy. You could tell the ones who liked kids by the plants they often chose, fun ones like squashes, scarlet runner beans, and bright flowers like Cosmos, Marigolds and who could not resist Nasturtiums!  Nasturtiums(Tropaeolum majus) are a fond memory of many of us who had them in our garden when we where young.

The bright array of colors found in Tropaeolum majus always appeals to children of any age.

Tropaeolum majus orginally is from South America, growing in an area from Bolivia and Columbia and is said to be found in areas such as central Chile as well.  Nasturtiums were first brought to Europe by Spanish around 1500, it is likely seeds where carried back. In South America the plant was used for medicinal purposes such as treating coughs, colds, flu by creating at tea. Topically it was used in poultice for for cuts and burns. Nasturtiums are high in vitamin c and have natural antiboitics in them. It was in Europe that the plant was first used for culinary purposes.

Here the trailing variety of Nasturtium is used as a simple but charming ground cover that is a riot of color during summer and autumn.

As a culinary plant Nasturtiums have a lot to offer: the leaves, flowers, stems and buds can all be used and impart a spicy sweet flavor reminiscent of Garden Cress (Lepidium savaticum) or Water Cress(Tropaeolum officinale). The flowers and leaves are used in many ways from salads to sandwiches, in dressings and spreads. The flower buds are pickled and used as a substitute for capers. I like to use the stems as they are especially spicy and add them into salads, my dad who loved extra spicy things was surprised with the intensity of heat in them.

Nasturtium leaves are unusual as the stem is attached to the very middle of the leaf giving it a curious round shape which is part of this plants charm.

The unusual shape of the leaves and flowers lead Linnaeus to choose a an interesting botanical Latin name for Tropaeolum majus. ‘Trope’ is from the Greek tropaion or trophy which refers to how the round shields(leaves) and helmets(flowers) where hung on a pillar which was said to be a sign of victory on a battlefield.  The common name Nasturium comes from the latin ‘nastos’ (nose) and ‘turtum’ (torment) and this refers to the spicy taste of the plant. Majus just means big which refers to the size of the leaves.

The stained glass coloring of the Nasturtium flowers and the curious rounded leaves have inspired for many famous artists and writers.

Nasturtiums have long been known but during the Victorian era, into the early 20th century seemed most charmed by these plants. From Monet, William Morris, Moorcroft(pottery) to Tiffany’s famous glass, the plants where used everywhere as a charming and attractive subject. Nasturtiums of course are a famous subject for botanical prints. Who does not love a bouquet of the fragrant brightly colored Nasturtiums on a table or windowsill to cheer one up.

This bunny hides in the Nasturtiums in the Childrens Garden at Glendale Gardens.

Tropaeolum majus is an easy plant to grow for the new or junior gardener. The seeds are big and easily handled and once planted germinate and grow quickly. They are not fussy and like sandy light, poorer soils, but will do equally well in richer soils although it will produce more leaves and less flowers. Full sun is most important to get the best showing of flowers unless you are in a very hot climate where a little shade in the afternoon will be appreciated. although they are somewhat drought tolerant regular watering will insure your plants continue to bloom for a long time. dead-heading the spent blossoms will help the plant to continue to bloom for months. Nasturtiums are considered to be hardy annuals and can tolerate a light frost, a hard one will kill them outright.

The Nasturtiums here are a cheery welcome to this garden.

There are 2 main forms of Nasturtiums, the compact(or dwarf) and the trailing. The dwarf are at the most 45cm(18in) wide and tall with the trailing form being able to cover a 1m(3ft) space per plant. The beguiling flowers come in a vast tapestry of single-colors, bi-colors and blends ranging from the blackish-red ‘Mahogany’ to a pale buttery yellow and all ranges from red through scarlet, orange and yellows. Many named color varieties, singles, doubles and variegated(‘Alaska’)  and dark leaved(‘Empress of India’)  forms can be found in seed strains and are cheap to buy. Seed is easily saved for next year and often will reseed and grow in the same spot for many years.

Nasturtium 'Mahogany' has the darkest flowers that i have seen here in Victoria.

Tropaeolum majus can be used in the garden in so many ways: edging, colorful filler for early bulbs and bloomers, childrens’ first garden, ground-cover, edible garden, fragrant garden, self seeding garden, old fashioned gardens, window boxes and containers, formal and informal settings and as artists subjects and fairy gardens.

The Master Of All The Gardens.

The first time I was introduced to todays plant I really did not appreciate its sublime beauty. It was at I time when I knew to gardening in this  mild  west coast climate which was like coming to a treasure trove of exotic from the plant desert i had lived in.  The plant in question was in the ‘white garden found in Park and Tilford Gardens where I was doing my practicum over the summer months. With experience I have learned big and bright are not always the most easy to work with in designing gardens whereas sublime and subtle are often the key to the best. Astrantias major (Masterwort) are delicate and sublime at the same time while being outstanding garden plants which deserve to be included in many more gardens.

Astrantia major, or Masterwort has slight variations in shades of color and flower size.

Astrantias have long been known to gardens in Europe where they grow amongst the alpine meadows in the mountains of Austria through the Swiss Alps, and  into the Pyrenees of north-west Spain.  There at the  high elevations and they bloom from July into September.  (Great) Masterwort is first noted by English herbalist John Gerard(1545-1611-12?) in 1596 in his famous  publication ‘Great Herball, or Generall Historie of Plantes’. In this book he wrote a detailed description of all the herbal plants which he had collected and grew at his garden in Holborn.

Frothy Astrantia major blooming with Alchemilla mollis make a beautiful floral display in this dappled spot.

Astrantia are without a doubt are recently being discovered by gardeners here in North America. I was lucky that many years ago to have experience them in the ‘white garden’  as I did not see them again until I came to Vancouver Island and worked as a grower at a nursery here. There I soon found that there were several color forms from dark red through pinks and creams. My favorite Masterwort was one called “Shaggy’ which has a large deeply toothed bracts which are green tipped on cream, it is sometimes sold as ‘Margery Fish’ and should only be propagated by division.

The tiny fertile flowers of Astrantia major are found in the middle of the papery green tipped bracts.

Astrantias are now used in many types of gardens as they are extremely versatile.  Margery Fish, the influential English Cottage Gardener recognized their charm, as have many of the well know garden writers and designers of today.  You can use Masterwort in full sun or nearly  complete shade and still get a respectable showing of flowers. the flowers are extremely long-lasting because they are papery and dry quite well, this guarantee that they make their way into florist shops for their work. The leaves are clean and attractive.

One of the many red forms of Astrantia major which are available now.

Growing Masterwort is fairly easy as long as you remember a few important things. Astrantias like rich fertile soil which has the ability to retain some moisture during dry periods, these plants sulk if they get too dried out. They will flower best in full sun as long as there is sufficient water available.These are plants which do not like to have their roots disturbed  therefore care must be taken when moving or dividing them, they can be slow to bounce back and patience is needed.  To get a prolonged  and repeat bloom remove spent flowers promptly, this will keep the plant vigorous.

Atrantia major will have a second flush of blooms after the first spent flowers are removed.

To increase Masterwort you can do it in several ways by division or by growing them from seed. Division is done in the fall or spring when Astrantias are still dormant every 3 to 4 years. Division is the only way to increase your named varieties and keep them true to form and color. Seed may collected and germinates naturally on site if the plants are happy or you can do it yourself. The seed is multi-cycle dormant and I used a refrigerator to artificially speed up the process. Plants from seed will take several years to bloom using this method.

Astrantia 'Sunnidale Variegated' has some of the most attractive of all variegated plants.

Before putting your Astrantias to bed in the late fall give them a side dressing of mulch and this will help them grow strong roots over the winter. Masterwort are listed as taking -20c(-4f) or zones 5 through 9.  These are tidy plant which for slowly spreading clumps of  30-60cm(1-2ft) wide. Hieght of the plants varies from 30-90cm (12-36in) high at the most, most are around 60cm(2ft) tall. New varieties are being introduced, the darkest red so far is ‘Hadspen Blood’, ‘Shaggy is said to have the largest flowers. Another Astrantia you can grow is Astrantia maxima which has pinker flowers with thicker bracts.

Here in the 'Cutting Garden' at Government House, the Astrantias are used as an informal groundcover.

Use Astrantias in your perennial border, shade garden, woodland areas, informal areas, cut flower garden or butterfly and bee garden. Masterwort mixes well with many plants from Ferns to Rodgersia as well as Hostas, Heuchera, Tellima and Tiarellas and many others.

They Only come out in the Winter Here.

Were I come from the climate is cold and some types of plants are not well represented in the wild or are do not grow there at all. An example is broad leaf evergreen plants. The only types which have survived the extreme cold are those which have adapted themselves to be short enough to be coved by snow during the long winter. Another plant which has adapted itself in a most usual way is the Licorice Fern(Polypodium glycyrrhiza) which grow here on the mild wet coast.

Polypodium glycyrrhiza or Licorice Fern growing on top of a rocky ledge amoungst the moss.

I first saw Licorice Ferns in a park in Surrey, near Vancouver. They are not nearly as noticeable as they are here and that may be due to there being more rocky outcrops for them to hang off of and be more exposed. At this time of the year these plants stand out because the fronds are fresh and green, newly grown during the late fall. The adaption Polypodium glycyrrhiza uses is to be deciduous during the dry season summers here. As we approach late spring Licorice Ferns drop their leaves and go dormant over the dry hot summer. In early fall with the first rains of the approaching wet season the ferns wake up and start to grow a new crop of leaves.

Remnants of other years growth are seen at the base of this clump of Licorice Fern.

Licorice Fern is a member of the Polypodium family of which there are up to 100 members.  They are spread throughout the world with the largest contingent found in tropical areas. All members of the family spread by rhizomes which are specialized stems that creep along the ground. The name Polypodium comes from ancient Greek and means: ‘poly’- many, and ‘podium(ion)’- little foot.  Glycyrrhiza is also from Greek and refers glykys(glycyr- sweet) and ‘rhiza’-root, this refers to the sweet licorice flavor of the root. The sweet flavor comes from ostadin which is a steroidal compound that is 3000 times sweeter than sucrose.

Several different clumps of Polypodium glycyrrhiza growing along Landsend Road in North Saanich.

The Licorice Fern grows along a narrow strip which extends from central California through Oregon, Washington all the way up to Aleutin Islands. The area extends to the western slopes of the Coastal and Cascade Mountains and goes all the way to the ocean and then hops over the the major islands along the Pacific Ocean of North America. Polypodium glycyrrhiza grows in dappled to fully shaded sites which are often along road edges and rocky outcrops.  These ferns are also happy creeping up the bases of Big Leaf Maples(Acer macrophyllum), larger Alders and Garry Oaks. They are epiphytes which do no damage to the trees which they grow on. The fern roots have been used by native groups for healing sore throats and colds. The sweet rhizomes where sometimes chewed for the flavor. Licorice is one of only a few ferns which have been know to be eaten in various forms. The rhizomes were  eaten dried, steamed, raw or scorched.

You will find Licorice Ferns scattered through the gardens at Government House.

Licorice Ferns grow in areas which often have very little soil. Often these sites have a layer of moss which spores of the ferns are able to grow in and develop into sheets of slowly creeping clumps of fronds. If you are lucky you will have a clump of these plants which will need little attention through the year. Many years ago I collected a piece of Polypodium glycyrrhiza which I have grown in a pot for many years. I bring it out to be on my steps during the winter for some seasonal color and later tuck into a less noticeable corner when it becomes dormant. I have divided it several times and given parts away to other gardeners.

My Licorice Fern growing in a colorful bucket on a step near my door.

In their native habitat Licorice Ferns can be seen growing along side wild Sedums, Tellima, Tiarellas and Heucheras. These ferns are charming to see in the winter and add a touch of bright green in areas which might be dingy and dark in the many conifers found here. I find Licorice Ferns facinating in where they choose to live and how they seem to miraculously appear on what look like barren rocks after the first rains of autumn every year. I always look forward to their appearance.

In the right place Licorice Ferns are a luxuriant carpet.

Growing Licorice Ferns are as easy as taking a piece and planting it where you want. It needs water during the winter when it is growing, now that is not hard at all here.  they are listed as growing in zones 5(-10 to -20f) through 8(10-20f). If they like their spot they will slowly increase the number of fronds which come up. they grow to 2ft tall, but rarely ever give that impression as they are usually bent over.

A great spot to view Polypodium glycyrrhiza is the top area of Playfair Park in Saanich.
