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.

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.

Fried Eggs and Really, Really, Really Big Poppies!

The laziest part of summer, temperatures are at their peak and I just feel like dozing. In the garden it is a quite time, many plant are going into their decline after blooming earlier the season. With the heat many plants will droop, some will become completely dormant and start loosing their leaves. Others now will shine and come into their season of glory while showing how resilient they are and carry on as if nothing is happening. The Matilija Poppy, California Tree Poppy (Romneya coulteri) acts like it is just another day at the office and look beautiful and refreshing as ever.

Romneya coulteri is known as the Matilija Poppy or Fried Egg Flower.

Romneya coulteri is found in southern California  ranging through the Santa Monica to the Santa Ana Mountains near San Diego and then into Baja in Mexico. They are normally found growing in dry washes and canyon and gulleys where the conditions are very dry and the soil tends to be poor. The southern plants are classified as Romneya trichocalyx or BristlyMatilija Poppy. there are also hybrids which are known and are in cultivation. For the common gardener like you or I we can safely consider them to be one plant type as all forms look and grow exactly the same.

Part of the charm of Romneya coulteri are the petals which bring to mind the most delicate silk or crepe paper.

Romneya coulteri was first brought into the garden by Dr. Thomas Coulter(1793-1843). He was a botanist and explorer who served in Mexico. While he was there he managed silver and lead mines in the late 1820s to early 1830s. In his spare time he would explore the area. He had the foresight to envision that great cities would one day be established there. When he returned home to Ireland in 1834 he brought with him a collection of dried plant materials, insects and rock samples. He later became curator of the herbarium at Trinity College, Dublin. Here his plant samples were studied and included in the national collection which is now part of the National Botanical Gardens of Ireland at Glasnevin.

A large suckering clump of Romneya coulteri or California Tree Poppy is found in the White Garden at Government House.

It was at Glasnevin that Romneya coulteri was first grown in a garden setting in 1875. The delay introducing is likely partly due to getting viable seed to germinate as well propagating it which is difficult.  Romneya comes from honoring Thomas Romney Robinson(1792-1882) an important Irish astronomer. Coulteri is named for Dr. Coulter who is mentioned above. The name was chosen by William Harvey in 1845 to honor the two men who were his contemporaries and friends in Ireland.

This Romneya coulteri is in a hot, full sun site on a street near Cook Street Village.

Even though Romneya coulteri comes from sunny California it grows very well in many other places which are not so warm or sunny. Here in the north(wet)west it is an increasingly common sight in larger gardens. people have come to appreciate its long blooming, drought tolerant qualities. Another thing that is loved is the beautiful grey green foliage which works so well with many other colors. The blooms also have a light delicate fragrance which is much-loved.

The attractive jagged greyish foliage of Romneya coulteri.

Like all members of the poppy family care must be taken when placing Romneya coulteri in the garden.  This not a small plant, in fact it can grow to nearly 3m(10ft) tall and nearly as wide, this is why this plant is often thought of as more of a shrub than a woody based perennial. California Tree Poppies spread by underground rhizomes which can go under paths, driveways and even houses and pop out on the other side. Here they generally grow 2m(6ft) tall or less. Choose a site which will give them the space they need and will not impact other more delicate or less vigorous plantings. these plants are not fussy about their site as long as it is well-drained, soil can be poor or rich, no amendments or fertilizer should be given. When first planting they need water about once a week and then in following years should be left alone.

Matilija Poppy stems are long and still and often need staking.

Romneya coulteri plants have stiff woody stems which grow best with scant water and full sun and less likely to flop. This stately plant works well in the back of borders or the very center of large beds where it can support other plants leaning and climbing up its mighty stems. It is great in dry areas or those which will naturally  have less pampering. It attract butterflies, bees and other insects. It would be useful in mass plantings or even as a very coarse tough groundcover for dry neglected areas.  In warmer areas it is almost evergreen, here it is often treated as other perennials and cut down in the fall when it goes dormant. It is rated as zone 6(-10f) by some authorities and zone 8(-12c or 10f) by others. I think must be related to the winter dampness and drainage.  Propagation is best done with young root cuttings.

The bristly seed-heads are rather small compared to the enormous 5-6in(12-15cm) diameter flowers.

The sap of Matilija Poppies was in the past medicinally for skin and gum problems and for stomach upsets. There is a charming legend relating to the flower which claims the petals of the flower were believed to have been made of the soul of a heart-broken maiden who died. The Chumash (native people of the area which this plant grows) gods changed her into the pure white petals.

Ocean Spray, Panicles and Discs.

Every season there is a plant that you really notice here on the island which you do not see in elsewhere. That is because we have a unique eco-system. In the winter the Garry Oaks are most noticable, in the spring it is the fields of blue Camas and the delicate Easter Lillies (as old timers call the plant) and during the summer there are these shrubs growing all over with white panicles of tiny flowers which are not seen on the mainland.  That plant is wonderfully named Ocean Spray(Holodicus discolor) and you see it everywhere right now.

The frothy white panicles of Ocean Spray(Holodiscus discolor) is seen everywhere here in the early summer.

Ocean Spray may look like a woody overgrown  Astilbe but is actually a member of the Rose (Rosacae) family, it’s all in the microscopic flower structure you know!  Holodiscus discolor grows here on southern Vancouver Island and then south through to California. It grows surprisingly scattered in areas of the southern  interior of B.C.  into Idaho, Montana and south  ending up in Nevada. sometimes the interior form is classified as Holodiscus dumosus but it is unclear if it is possibly a variety or seperate species. It grows in a range of areas because it is quite drought tolerant and hardy.

A typical Ocean Spray growing amongst the grass and rock.

Ocean Spray is 1 of 8 in the species Holodiscus that range down the North and South American coast from British Columbia to Bolivia. The Greek name Holodiscus refers to the ‘disc’ structure in the flower and discolor refers to the leaves which are a greyish color on their undersides.

A panicle of thousands of tiny slightly fragrant, disc-like flowers make up the showy plume of Ocean Spray.

Holodiscus discolor was introduced by David Douglas in 1827, at that time is was thought to be a type of Spiarea and was later taken out of that species and renamed. Ocean Spray has long been used by native groups for many things. The wood is known to be very hard and the branches were harvested and used for tools, furniture and many small objects. The wood was often prepared by further hardening using fire and then polishing using Horsetail(Equistum). Arrows, spears and harpoons were also made this way.

Holodiscus discolor is a multi-stemmed shrub which can be pruned to show of the beautiful bark.

When the leaves of Holodicus discolor come out in the spring they often have a nice burnished color which can continue into the early summer, in the fall they turn golden and glow out among the other vegetation.The leaves and flowers were in the past used for medical purposes, tonics were made to treat a wide range of maladies such as smallpox, measles, chickenpox and as a blood treatment.  The leaves were made into poultices and were used on sore lips and feet. The bark was ground,  with oil and then applied to burns.

The attractive leaves of Holodiscus discolor are often burnished in the spring and turn golden tones in the autumn.

Ocean Spray is a fast growing, multi-stemmed shrub which has an arching habit. It can grow to 5m(16ft) high by almost the same. Water, Soil and pruning can keep it well in control, I have seen much smaller shrubs which grow little over 1m(3ft) in hard to grow in sites. Holodiscus discolor can be pruned up and thinned out to make a more delicate and useful plant. These plants grow in full sun to part shade, they are often seen as under-story shrubs in the Garry Oaks here. Spent flowers can be removed as they are somewhat unattractive when they are finished.

A path in the Woodlands at Government House takes you through a natural arbour of Holodiscus dicolor shrubs.

Holodiscus discolor can be used in large gardens or borders. It also fits in native gardens, drought tolerant locations and the flowers and seedheads are butterfly and bird attractants. Little is needed to be done as these plant survive on poor to good soils and summer droughts. they also are good for retaining soil on slopes and grow right along the ocean-side (Ocean Spray really is a good name).

I found this wonderful pink tinged Holodiscus discolor and think it should be propagated and sold as a new color variation.

Holodiscus discolor is rated at hardy to -30c(-22f) or zone 4b-9a.  I think you should choose plants grown locally or at least as close to the temperature range as where you are to assure it will survive if you come from a colder area.

Catch A Shooting Star.

I have been fortunate to have worked as a grower at a nursery.  This gave me the opportunity to grow plants which are not that well known. Some plants aren’t well known because they are hard to grow while others just have a false reputation for that. One plant I grew was the eastern(North American) form of a local plant. I never saw the local plant until a few years ago when i was with my father driving near Nanaimo which is north of here. It was magical, carpeting a dappled area in the woods. Last year I finally found Henderson’s Shooting Star(Dodecatheon hendersonii) in many places.

Dodecatheon hendersonii is known as Broad Leaved Shooting Star.

Henderson’s Shooting Star is a very delicate looking plant which grows amoungst other more showy plants. it is often in bloom at the same time the local Erythronium oregonium(White Fawn Lily) is and grows in the same places. The hot magenta flower color helps it stand out even though the flowers themselves are quite small.  The shape of the flower, with it’s extremely reflexed petals make it look quite unique.

An extremely rare white form of Dodecatheon hendersonii.

Shooting Stars are a strictly North American species. The most commonly grown member of them is an Dodecatheon meadia which is found in the east growing  from Pennsylvania to Manitoba and south through Georgia and Texas. In the west we have many species which overlap in some areas. Dodecatheon hendersonii is probably the most western as it grows on Vancouver Island, the Gulf Islands and moves  south to west central California. On the mainland it grows on the western side of the coastal mountains though the Siskiyous and the Sierra Nevadas. There are at least two named varieties. Var. hansonii is found in the Siskiyous and scattered locations in the Sierra Nevadas. Var. hendersonii is more widespread and found along coastal B.C.  to southern Oregon.

The leaves of Dodecatheon hendersonii lay flat to the ground unlike most others of the species.

Dodecatheon are members of the Primulaceae family. Dodecatheon is Greek; Dode(ka) meaning 12 and theo(s)n meaning god. The word dodecatheon refers to the 12 principle or most important gods which resided on Olympus. Pliny gave this original name to Primulas which grew where he lived. Primulas were thought to be under the care and protection of the 12 gods. The reference to the gods in the scientific name is thought to note that the flowers look somewhat likes thunderbolts which would be cast down on earth the gods when they were unhappy about what was going on. Hendersonii refers Louis Forniquet Henderson(1853-1942) who was the first botany professor at the University of Idaho.

Dodecatheon hendersonii are seen on mass along the sides of Old West Saanich Road near Victoria.

Henderson’s Shooting Star grow in shallow soils which are damp during the spring growing season and then become bone dry during the long summer droughts which can extend into October here. This is the perfect type of situation for these plants. Often I have found them growing amoungst the Camas leaves, along rocky edges of roads and on moss covered bluffs.

These bright magenta blossoms of Henderson's Dodecatheon will soon be replaced by brilliant blue field of Camus.

When growing Dodecatheon hendersonii it is best to reproduce their local environment the best you can. If you are successful they will seed themselves and you will have a nice colony to look forward to every spring.  plant in a mossy mix with rich soil, make sure it will drain adequately during the winter rainy season. They prefer to live below deciduous trees or shrubs or along the edge of such to be protected over the summer. These plants go completely dormant over the summer therefore it is wise to mark their site so as not to dig them up accidentally.

Henderson’s Shooting Star grow between 10 and  20cm tall(4-7in). They can grow taller if they are in richer soil. Here they tend to be in the shorter range. They are likely to be hardy to -10c(14f) or slightly colder. The last two winters have had spells of -10c and I think they have been more abundant than when the winters are warmer, maybe it is less likely they will rot. Slugs love these plants especially when they are just coming out of the ground in the early spring, protect them from these raiding feeders.

Can you imagine having a huge patch of Henderson's Shooting Stars growing wild in your backyard.

Stalking the Oso(berry)!

This time of year, no matter where I am, up north in deep snow, down on the coast in the rain or somewhere else when the sun comes out I want to either work a garden or explore in the woods.  This year the spring weather has come extraordinarily early and since I have recently moved I have started explore new areas in the city. My first stop was to change my library card and to explore  Colquitz River Trail which runs along the river of the same name. I was hunting for the not so elusive Osoberry or Indian Plum(Oemleria cerasiformis)plants which are in bloom now, I stalked along the walk and …..alongside the path were several!

The Osoberry is one of the first native plants to bloom.

On gloomy wet days when I go for a walk I see these shrubs with their glistening white racemes of pure white flowers which hang from the tips of branches like  perfect dew drop earings. The Osoberry is a small tree or more commonly shrub which lives on the Pacific side of the coastal mountains, its range is from Santa Barbara County in U.S.A. north though into southern B.C. One of its common names refers to the fruit (fleshy drupes) which when ripe look like tiny thumb-sized Italian plums, and indeed they have stones  which are also perfect miniatures of that fruit.

The Indian Plum has plentiful fruits, but you better be quick to harvest them.

The fruit is ripe when it is bluish black and was eaten by local native groups, they savored them fresh, cooked and dried.   Oso(berry) refers to bears liking to eat them. Birds (Robins), squirrels, deer, coyotes and many other animals love to feast on the fruit as well. Let us not forget the bees which enjoy this early source of nectar.

Indian Plums can be found in many parks here, this group is found by the bathrooms at Beacon Hill Park.

Native people also used parts of the Osmaronia cerasiformis medicinally.  Burned twigs were pulverized, mixed with Oolican grease and applied to sores. A tea made from the bark was used as a purgative and tonic. Decotions where made for tuberculosis. It is said to be not only anesthetic  but an aphrodisiac as well. Osoberry is a member of the Rosaceae(Rose family) whos seeds often have small amounts of hydrogen cyanide in them. hydrogen cyanide from these types of sources  has been shown to stimulate respiration and improve digestion if carefully administered by a professional.

Colquitz River Trail is a good area to view Osmaronia cerasiformis.

To my eye Osoberry are vase-shaped shrubs which are delicate looking throughout the year, this is partly do to the attractive thin leaves which keep their bright green coloring until the fall when they change to a clear butter yellow. It is not a densely leaved shrub therefore it never looks heavy or lumpy, but has a more wispy quality to it. In the winter without leaves the form of these shrubs can be highlighted.

Finnerty Garden has done a wonderful job pruning their Osoberry into small tree forms.

Osoberry is seen in many areas here, along paths, roadsides, meadow edges  and creeks and in many rocky areas growing under the Garry Oaks. They are in full sun or dappled light. They like rich humusy soils which can retain some moisture during our dry summers here. if they become too dry during the summer they will start to drop some of their leaves. They take pruning very well and this should be done after they have bloomed. They usually are pruned for shape but also can be cut to the ground to revive them and tidy them up.

Osoberry are male or female plants and often grow in thickets under Garry Oaks as seen here at Government House.

Indian Plum are male or female plants. If you want a good crop of berries for the wildlife or you, you will have to have both sexes of plants.  I have seen incredible crops of berries and have made tasty syrups and jellies which are similar to cherry flavor. These plants grow to 6m(20ft) high and 3.7m wide in places where they are most happy. They are rated zones 7 though 10, cold tolerant to -18c(10f).

This unripe crop of Indian Plums is high above my head.

A Garry Oak Acorn For My Thoughts

One of the most noticeable things about southern Vancouver Island is how dry it is for long periods of the year. We often have little or no rain from late May through until the end of September. This is a very tough situation for most plants to endure if they are not adapted to it. I have seen many shrubs and trees scorch from the heat combined with lack of sufficient water. Luckily for us many native plants here are unusually attractive and grow well in the stony ground on the island. One tree which is endemic here is the Garry Oak (Quercus garryana) which stands out at this time of the year. it is also known as the Oregon Oak or Oregon White Oak.

Garry Oaks at Beacon Hill Park in Victoria.

There are 3 varieties of Garry Oaks which live in Western North America. Quercus garryana var. garryana is found here and lives in the largest area which ranges from Southern California, along the coastal mountain ranges up to southern Vancouver Island and the gulf Islands. The variety var. breweri is found in the Siskiyou mountains in Oregon  with the final variety var. semota found in the Sierra Nevada area. This Oak was named by David Douglas to honor Nicholas Garry who helped him in his collection of plant samples in the Oregon area. Nicholas Garry(1782?-1856) was employed by Hudson’s Bay Company and later rose up to be the Deputy Governor of the company. Garrya elliptica is also named after him.

There are some majestic Garry Oaks found at Holy Trinity Church in North Saanich.

Garry Oaks are the only Oaks found in Western Canada and they are part of an endangered ecosystem which is in a very small area of southern British Columbia. Garry Oaks are very representative of the 116 species of plants, animals and insects which are found here and no where else in the world. This delicate ecosystem is under attack  mainly from expansion of human settlement and introduction of invasive and destructive species  from other places. large areas have been altered and changed and it is just recently that we have started to protect some of these remaining sites.

Sea Blush, Common Camas and Shooting Stars are but a few of the species growing amongst the Garry Oaks.

Garry Oaks have never really been important to the survival of native groups here.  They made combs and digging utensils with the wood or used it for fueling fires. The acorns were eaten but were not considered a choice food, but could be roasted or steamed and eaten.  Garry oak was known to be used medicinally for a treatment for tuberculosis and used as a drink for women before child birth.

The thick ridged bark protects the tree from fires which were used in creating Camas fields that native peoples farmed.

Quercus garryana generally have broad spreading rounded crowns which are made up of thick ascending crooked branches. These trees grow to 40-90ft (12-28m) tall  and nearly as wide. In areas where there are other competing plants these trees will often grow tall and gawky but in an open meadow their true form is seen. Young trees to around 25 years of age often look scrubby and will often be seen growing in groups.

These Garry Oak are found in Playfair Park and in the spring a sheet of blue Camas bloom underneath them.

Garry Oak are slow growing trees which will grow 8-12(20-30cm) in a year. They develop long tap roots and are amost impossible to transplant after they have been in the ground a few years. They need a sunny open site with very well drained soil. They do not make good lawn trees as they resent being watered during the summer and it can also cause them to become diseased. They do have natural insect pests which are often seen on the undersides of the leaves. These can become disfiguring  to the leaves some years but in others are hardy present at all. If you have the right site and would like a tree which needs little attention during the year, you might want to look into to this species or one of the other Oaks. Garry Oak grow in zones 6 through 10 (-10 f or  and higher temperature).

Male flowers are separate from the females on the same Garry Oak tree.

The Colorful Dogwood Triplets.

When I was little my mother would talk about how beautiful certain trees and shrubs looked in the snow.  She would speak of how beautiful the Birch looked with their stark black twiggy branches would show up so well against the white background. She also talked about the golden Willow branches which poked through the snow banks. Probably the most showy shrub which grew at the bottom of the lane near our house was the Red Twig Dogwood with it’s wine colored stems. Cornus (sericea)stolonifera is one of 3 similar species grow here and through the northern areas right around the globe.

Red Osier Dogwood growing along roadsides is a common sight here.

There are several species of Red Twig Dogwoods which are so similar that you can’t really tell them apart at a glance. They all grow in shrub form, have almost identical flowers and reddish colored stems. Cornus stolonifera(sericea) which is the most vigorous grower extends from Alaska south to northern California and across North America through to Virginia. it has creamy berries with a bluish tinge.  In Europe Cornus sanguinea is found which has black berries. Moving farther east we come to the final type; Cornus alba which is found from Siberia through Manchuria into to Korea and also has the creamy berries.

Cornus stolonifera 'Flavirimea' is one of the brightest bark forms of shrubby Dogwoods.

These three Red Twig Dogwood have some of the most attractive barks in the plant world. Many colors ranging from golden through peach and scarlet and then into maroons to almost black are represented in forms which can be found in nurseries. the deeply veined leaves have smooth edges and can be variegated in shades of cream, gold and even flashes of peach. Fall brings another show of color ranging from deep maroons through to peach and gold.

The fall and winter color of Cornus sanguinea 'Midwinter Fire' in all it's glory.

All three species  of Red Twig Dogwood have flat cymes made up of tiny cream colored flowers, this flower structure is also seen in other Cornus species. In the right location the flowers will turn into bountiful crops of attractive berries which the birds like to eat later in the winter.

The many tiny Cornus stolonifera flowers have a slightly soapy scent.

The berries that follow the bloom can be copious and attractive. Birds like to eat them, but we would find them too bitter. Cornus alba has black berries which I have never seen. Here the local cornus stolonifera produces good crops year after year. The seeds of these plants are amazingly hardy. Tests have been done on them taking them to -320 f  in a lab, and then these same seeds have been germinated!

The attractive berries of Cornus stolonifera each contain a large flat seed.

Red Twig Dogwood are easy to grow and adaptable to many conditions. they need require a site in full sun with plenty of water. They like rich soil but are tolerant of poorer soils. Often these plants grow in wet area and can be found along lake sides and in ditches.  To produce the best stem color it is necessary to prune every 2 to 3 years and remove the older stems. Although these plants can grow to heights of 12ft(3m) and width of similar proportions you rarely see this unless it is in a wilder area. Normally these plants are easily controlled by pruning to 3 or 4ft (1-1.5m) heights.

Cornus stolonifera 'Arctic Fire' has some of the best red stem color.

As mentioned these are extremely hardy plant which grow in zones 3(-40c or f) through 8(-1c or 10 f). Because of there hardieness this is a good shrub to use in colder areas where choice is limited. It can be used in many ways such as mass planting, formal or informal hedges, foundation planting or as an accent. Various color forms make an excellent winter color feature when this plant will really stand out. Cut branches make a beautiful addition by giving bright color and height to bouquets and winter arrangements. The red branches are great for festive decoration.
