I have come to like many of plants that have been in gardens for hundreds of years. I love to find out the stories behind their common names. Some plants I have grown and others I like from afar, most of these plants have shown that they are still worthy of being in a garden somewhere. One plant has I like has velvet-like leaves and tiny chartreuse flowers. I bet you know what I mean and if you can not guess …..Lady’s Mantle(Alchemilla mollis) is its name.

Tiny chartreuse flowers and the sage green velvety leaves of Lady's manltle (Alchemilla mollis) are the feature most loved by gardeners and florist alike.

Tiny chartreuse flowers and the sage green velvety leaves of Lady's manltle (Alchemilla mollis) are the feature most loved by gardeners and florist alike.

Lady’s Mantle is a plant that comes to us from northern Greece east into western Russia and into the Caucasus then south all  into northern Iran. In its natural habitat it grows in wide range of habitats from stream banks to meadows and wind swept plains and mountainous areas.  A close relative Alchemilla xanthocholra was formerly named A. vulgaris and is the European version of Lady’s Mantle. It is said to be less hairy than A. mollis.

The green-blue leaves of Alchemilla mollis are seductive and beautiful especially in the rain. One can really imagine a Lady's Mantle made of soft material which looks like this foliage.

Alchemilla mollis is a plant often seen frothing over the edges of paths or edging paths with its softness in flowers and foliage. It is a beautiful foil to cover unsightly bare stems of all sorts of larger plants and is used this way in many places. The name Lady’s Mantle is said to have come from the edges of the leaves that are similar to a cloak (or mantle) a lady would wear. The orgin of Alchemilla is unknown but is thought to possibly have originated from a Arabic world that has been ‘Latinized’.  Mollis means soft or with soft hairs and refers to the leaves.

Species of Alchemilla and especially the look-a-like Alchemilla xanthocholra have been much used in medicine in the past.  The plant contain salicylic acid (ASA), a strong pain reliever that we use today. Lady’s Mantle was used as a herb for women and was gathered in June and July, the roots were used fresh while the leaves were used when dried.  It was used for painful periods and was especially  associated with excess bleeding as well as during menopause. It was also used as an astringent in mouth washes for sore gums and ulcers.

In this artistic garden the charteuse flower colors of Alchimilla mollis contrasts with the more somber plum and coppery rust tones.

Alchemilla mollis is a versatile plant which can be used in many places from fairly deep shade to full sun. That versatility also applies to the growing conditions as it is not to fussy in soil type as long as it does not become water logged or completely dried out.  This plant stays a fairly compact 45 cm.(18 in.) wide and high.  It is a very hardy plant and will survive temperature down to below -40 c. or f. (zone 2-9).

Here Alchemilla mollis take over from hardy Geraniums and leads the Hostas and Asilbes in a wave of color and texutres.

 Lady’s Mantle can be used in many ways but it will always be more informal as the plant is loose looking and soft. The most often seen use is as edging along paths where it spills over and softens edges. Another use is to hide more gangly larger plants long stems. It works well in large containers and give an all year show of color and texture. It should be found in all floral arrangers gardens as the leaves, flowers and seedheads all are used in bouquets. The chartreuse color of the flowers and sea-green foliage of Alchemilla  mollis is beautiful in most gardens and the colors are appealing to the eye, many artists have been inspired to include it in painting and other works. it can be mass planted and used as ground cover and is especially attractive in rocky areas popping out amongst the rocks.

We I was small we would visit my grandmother(my father’s mother) in Williams Lake which was closer than my other grand parents. She came from Scotland and had an accent any many things from her family at her home. She also special scented soaps and that scent I now always associate with her. The soap was Lavender scented (from Yardley) and I still love that fragance. Here in Victoria we are able to grow that most famous of aromatic plants in many forms. The Lavender plant which most reminds me of the soap in its scent is Lavandula angustifolia ‘Hidcote’ (Hidcote Lavender).

'Hidcote' Lavender Lavendula angustifolia 'Hidcote' has the fragrance that most reminds me of my grandmother.

'Hidcote' Lavender Lavendula angustifolia 'Hidcote' has the fragrance that most reminds me of my grandmother.

Lavenders are plants which originate form the mountainous areas of France and Italy and Spain. The numerous species of plants have been used for millennial for fragrance, medicinal, herbal and culinary purposes. Different Lavenders have slightly different scents, some are more resinous(pine scented) while others are are less potent and kind of dusty (almost musty). What we think of as ‘true’ English Lavender scent is Lavandula angustifolia with bright flower that are dried for sachets stuffing pillows,  used in oils lotions, soaps and pomanders. The scent is said to be calming and is used that way in herbal medicine. The flowers have many culinary uses from sweets to teas and inclusion in meat dishes and other savory foods.

Hidcote lavender is included in this herb garden.

Hidcote lavender is a true English Lavender selection( selected in 1950) which is named after the world-famous  garden at Hidcote Manor near Chipping Campden, Gloucestershire.  Hidecote Manor was an estate whose gardens were developed by Lawrence Johnson (1871-1958). Johnson was born in France to an American father who was a wealthy stockbroker. Lawrence Johnson has nor formal horticulture training but was extremely artistically talented. Lawrence when to Cambridge and graduated with a degree in history from Trinity College and later joined the British army fought in the Boer War and World War 1. In 1907 his mother bought Hidcote and he went to live with her in the 200 acre estate.

For the next 41 years Lawrence developed 10 acres into a magnificent series of garden rooms each with its own surprises and unique features.  he was much influenced by Gertrude Jekyll the Arts and Crafts movement which was primarily located in Great Britain.  The gardens of Hidcote were seen as being so important that the National Trust selected them for their first example of gardens to include in their collection of places of cultural heritage. 150,000 people visit the Hidcote gardens every year to learn and get inspiration from them.

Most lavenders grow well on Vancouver Island even though we have much more rain that would occur where they originate, drainage is important. Here in Victoria most gardens are on top of a layer of clay and fine sand which means placing any Lavender is tricky. Hidcote Lavender seems to do the best of all the different species which are grown here as it is quite hardy and will take more moisture that some others which will regularly die or be severely damaged during colder winter here.

Hidcote Lavender is just one of the massed plantings used to create color throughout the year on the main street through Brentwood Bay.

Hidcote Lavender is just one of the massed plantings used to create color throughout the year on the main street through Brentwood Bay.

Growing Hidcote Lavender is easy in the right place. You need full sun and well-drained soil especially in wetter climates. The best plantings I have seen are completely exposed to the elements such as those in the Terraced Gardens at Government House. There they grow in rocky niches in soil which probably is not that deep and they will bake in the summer. Although Hidcote Lavender is a shorter dense plant it will do well with a cutting back after the flowers start to fade in color. This will set a flush of new vigorous growth before autumn dormancy will set in. Hidcote lavender grows up to  30-45 cm. (12-18 in.) tall and about as wide. It is  rated at tolerating -34 c.(-30 f.) or zone 4.

Here Hidcote Lavender is tucked in with Heaths, Heathers and small assorted succulents.

Hidcote Lavender can be used in a variety of ways such as in containers, as a formal or informal edging for paths, drought tolerant garden, deer or rabbit resistant garden, mass plantings or specimen plantings, as an accent, in herbal and fragrance gardens or collections.  True Hidcote Lavender is propagated by cuttings but what you get in most garden shops is a Hidcote strain of seed grown plants which generally are very uniform in their growth, color and size. This is an excellent seed strain.

At this time of the year I really become aware to the color of foliage in various plant in the landscape. Plants are still fairly fresh and their foliage is alive and vibrant with color. Colors other than greens stand out in ways that often fade as the season goes on. It is unusual to find a group of plants with more color than those of the Cotinus (Smoke Bush) family which gives a show from spring until late autumn.Their color ranges from black purples, wine reds, bluish green, green and into chartreuse yellow – and this does not include autumn tones which are just as show stopping!

The color tones in one branch of Cotinus coggygria 'Velvet Cloak' is remarkable

The color tones in one branch of Cotinus coggygria 'Velvet Cloak' is remarkable.

The genus Cotinus is a member of the family Anancardiaceae which also contains the  Mango, Cashew, Poison Ivy (Sumac) species and was at first classified as Sumac(Rhus) species until it was separated from the other members. It does not irritate the skin or have sap which can burn.

Smoke Bush(Cotinus) generally have brilliant autumn colors ranging from scarlet into to peach and golds.

Smoke Bush(Cotinus) generally have brilliant autumn colors ranging from scarlet into to peach and golds.

Cotinus is a small genus of 2 or possibly 4 species of which coggygria and obovatus are the best known.  Cotinus coggygria is the species which is best known in the landscape and originates in Europe from France into Eurasia and possibly all the way into China. The far eastern representative coggygria sometimes listed as another species C. szechuanensis (var.  szechuanensis). The other well known species is C. obovatus and comes from North America particularly in Tennessee, north Alabama, Missouri, Arkansas and isolated pockets in central Texas. All Cotinus species have been used extensively for a source of dye wood as it gives colors of orange-yellow and yellow coloring. The use of C. obovatus as a yellow dye source before the civil war in U.S.A. almost brought the species to extinction in its native habitats.

Cotinus 'Grace' is a cross between Cotinus coggygria 'Velvet Cloak' and C. obovatus.

Cotinus 'Grace' is a cross between Cotinus coggygria 'Velvet Cloak' and C. obovatus.

 Cotinus  is from ‘Greek’ kotinos meaning wild olive but why it is named this is unknown. Coggygria also comes from ‘Greek’ kokkugia- the name of ‘Smoke Tree’. C.Coggygria has been cultivated  in gardens for an unknown period but is first mentioned in the mid 17th century. The species form is not commonly seen in gardens as there are more exciting color forms.

The less commonly seen species form of Cotinus coggygria is seen here with its lovely green foliage.

Smoke Bush are well known for their colorful foliage and there are an increasing number of cultivars to choose from.  The oldest color form is probably C.c. ‘Foliis Purpureis'(Rubrifolius) which has rich purple -plum leaves which fade into to greenish tones as the summer progresses. C.c. f. purpureus(‘Atropurpureus’) refers to the coloring of the large panicles of purplish flowers. C.c. ‘Royal Purple’ (Notcutt’s Variety’) has leaves which start maroon red and then matures to black-purple(darkest of all forms) it holds its color well throughout the year and changes into scarlet autumn shades. C.c. ‘Velvet Cloak’ has red violet foliage which is dramatic, its floral display is longer than most. It holds is color well.  Cotinus ‘Grace’ leaves emerge in wine-red and has clouds of pink-tinged flowers. A new color yellow range has come out from a chance seedling found at a dutch nursery in 1990, it is C.c. ‘Golden Spirit'(Ancot’) – it does not fade out unless it is under-watered.

The 'smoke in Smoke Bush or tree(Cotinus species) is from the panicles of tiny flowers and then the whispy seedheads later on.

The 'smoke in Smoke Bush or tree(Cotinus species) is from the panicles of tiny flowers and then the whispy seedheads later on.

All Cotinus species drier areas often with rocky soil on slopes and hillsides. They have proven to be vary adaptable to many other situations and soils from heavy clay to sandy. They need full sun pr produce the best coloring and floral display. They need adequate watering while becoming established but later are much more drought resistant. They are pest and disease free but sometimes coloring tends to fade out in hotter southern areas, this is where coppicing helps rejuvenate the color. The best coloring is obtained by regularly pruning them hard, use a method such as coppicing to produce wanted effect.

Cotinus 'Royal Purple'(the darkest color) is coppiced to keep its best color and form.

All Smoke Bush are rated at zones 5to 9 and take cold temperatures down to -28 c. (-20 f.) In colder climates they generally are cut to the ground which is like the mentioned coppicing.  Cotinus can be used as specimens, in shrub borders,  as accents, masses, in less watered areas and can pruned into tree forms which are very effective. Cotinus have a lot of appeal in the shape of the leaves and wispy flowers to add to a garden along with strong color.

Cotinus 'Golden Spirit'('Ancot') was found as a chance seedling at a Dutch nursery in 1990 and holds its color well in the September garden.

I was listening to the local radio yesterday as I went about my business about town, they were interviewing a local vegetable grower who said crops are 5 to 6 weeks behind where they normally are at this time of year. I knew the season was behind although it seems to me that plants catch up at different speeds and some never really seemed to have been effected by the bad weather here this year. One plant which just rolls along without a care is Erigeron karvinskianus  Latin American Fleabane. It is rarely out of flower at any time of the year.

Erigeron karvinskianus (Latin American Fleabane) is a tiny sprawling plant perfect for containers,baskets and in rock cracks.

Erigeron karvinskianus (Latin American Fleabane) is a tiny sprawling plant perfect for containers,baskets and in rock cracks.

There are many Erigeron and most come from North America and as the common name tells you E. karvinskianus comes from more southern areas. It is found growing from Mexico south into Venezuela. In its native habitat it grows in the mountains at 1200-3500m (4000-11000  ft.) where is is evenly moist throughout the year. Spanish Daisy, Latin American Daisy, Santa Barbara Daisy or Mexican Daisy and even Bony Tip Fleabane – all are referring to the same plant.

With its tiny parts Erigeron karvinskianus does not seem out of place with other small plants here.

With its tiny parts Erigeron karvinskianus does not seem out of place with other small plants here.

Erigeron isthought to be Greek eri=early and geron= old man. Karvinskianus refers to Baron Wilhelm Friedrich Karwinski von Karvin (von Karvin Karvinski) 1780-1855. He  born in Hungary and was a naturalist with interests in Geology, Botany and particularly in the study of fossils from different periods. To this end he traveled to collect samples and the areas he went to was Brasil(1821-23) and Mexico(1827-32) . During his travels he sent back over 4000 plant specimens and several have been named after him, these include cactus, grasses and several others. He collected his sample of Erigeron karvinskianus while he was in Oaxaca Mexico.

Part of the charm of South American Fleabane lies in flowers which open white and change into pink as they age. This effect is also seen in other Erigeron species.

 Erigeron karvinskianus is a very successful plant since it has been grown at sea level and in some areas it has become somewhat of a pest. In Australia and particularly it is not welcome (in these areas it is recommended to plant Branchyscome  multifida which is similar looking). The selection ‘Profusion’ refers to the flowers but also could well refer to its ability to reproduce quickly. In Victoria it is controlled by the climate being on the very edge of it being able to exist as a perennial here, many plant will have died this winter and new seedlings will take their place.

Here native Sedum, Cotoneasters and other mixed plants blend together in the rocks with Spanish Daisy to give a pleasing contrast in textures and color throughout the year.

I first came to know this plant as a grower at a perennial nursery and thought that this plant might be a good container plant as it has proved to be in other areas. It has mainly been grown for this purpose as it is not hardy enough for most of Canada. Here it can be grown as a short lived perennial which reseeds to refresh with new plants. Victoria and nearby areas are the only places you will see it growing in gardens as a regular plant.

The diminutive flowers on wiry stems of Erigeron karvinskianus are long lasting as they go through their metamorphosis from pure white to deep pink.

Erigeron karvinskianus like full sun and well drained soil which can be sandy or even having clay like it is around here. It like even moisture to slightly dry especially in colder areas as excess wetness promotes rot. These plants can be used in many ways, as fillers, accent,groundcover, massed, in large rockeries as long as its not near delicate growing or extremely small plants. They are fairly drought tolerant and attract butterflies to your garden. They are rated as zone 8 -10 c. (20-30 f.) They grow 15-20 cm high and wide.There are several named varieties, ‘Profusion’ is the best known and there is ‘Snowdrift’ which has white flowers. It is also thought that the species E. moerheimerii is just a form of karvinskianus and should be listed as E.k. ‘Moerheimii’

This time of the year usually is warmer and the Roses would be in full bloom, I guess I will have to wait a bit more. In the meantime I am reminded that there are so many other plants which are now stealing the show and some of them do it in a way which is more subtle than just big wonderful blooms. Often we overlook fantastic foliage which accompanies the flowers. How about this novel idea, a plant which the foliage is just as much the star if not more, a tall order I would say! One plant I and many other gardeners would nominate is Achillea ‘Moonshine’ (Moonshine Yarrow).

Achillea 'Moonshine is part of the street plantings in Brentwood Bay and looks good year round, tidy foliage and bright non-fading flowers.

Achillea 'Moonshine is part of the street plantings in Brentwood Bay and looks good year round, tidy foliage and bright non-fading flowers.

Achillea ‘Moonshine’ comes from the famous plantsman Alan Bloom(1906-2005) and Bressingham Gardens. If you look through perennial plant books you will see the name Alan Bloom and Bressingham Gardens mentions many times. Alan Bloom came from a plant family, his father grew cut flowers and fruit for a living . Alan left school to go into the business, his wise father said he should try as many areas as possible to find where his interest were and he settled on hardy perennials. After working as an apprentice Alan started his first wholesale perennial nursery in Oakington, the place of his birth. It took only 4 years for Blooms nursery to become the biggest of its kind in England. In 1946 he purchased the Bressingham Hall (near Diss in Norfolk) which included 228 acres of land. He  began developing it during the 1950s and early 60s, during this time he also introduced nearly 200 newly named  plant selections and hybrids which originated from his nursery and the famous  gardens.

The golden flowers and silver foliage of Achillea "Moonshine" is bright and soft at the same time making it an easy plant to work into garden designs.

The golden flowers and silver foliage of Achillea "Moonshine" is bright and soft at the same time making it an easy plant to work into garden designs.

‘Moonshine’ Yarrow is a cross between A. clypeolata (silvery foliage ,strong chrome yellow flowers) and taygetea( ferny foliage and creamy yellow flowers). It was discovered as a seedling around 1950 and introduced into gardens about 1954. It was quickly recognized to be an outstanding plant and was awarded an A.G.M.(Award of Garden Merit) from the Royal Horticultural Society. The plant has proved to be one of the best ‘Blooms’ introductions and is seen in many situations from well maintained gardens to the tough street side planting.

The silvery foliage of Achillea 'Moonshine combines the delicate 'ferniness' of A.taygetea with the silver sturdiness of A. clypeolata.

I first encountered Achillea ‘Moonshine’ a the wholesale perennial nursery I worked at in the early 1990s and I knew at once that this was a great plant compared to the other Yarrows which were grown there at the time. The foliage was beautiful by its self and the slightly creamy yellow flowers seemed to bloom for the longest time. These plant were always quickly bought up by the local nurseries, landscape architects and designers who put in orders or came to visit the nursery to see the plant stock we had there.

Here Achillea 'Moonshine' is used as a way to hide unsightly Rose stems along the exterior of the Rose Garden at Government House in Victoria.

Achillea ‘Moonshine’ is an easy to grow plant which tolerate a good amount of neglect which makes it a very versatile plant for use in many situations. It does require full sun to produce the silveriest foliage and the most golden flowers, but, this is little to ask for such a grand reward! It takes most kinds of soil as long as its well-drained as wet feet can lead to trouble for most Achilleas. It is a fairly compact plant growing 60 cm.(2 ft.) high by about the same wide. Keeping it slightly under-watered will keep the floral stems from sprawling.Cut it back after its first flowering for it to repeat later in the summer. Divide it every couple of years to keep it vigorous.

Achillea 'Moonshine' is excellent as cut or dried flowers and will continue to give pleasure long after other flowers are spent.

Achillea 'Moonshine' is excellent as cut or dried flowers and will continue to give pleasure long after other flowers are spent.

Achillea ‘Moonshine’ is hardy to -30 c.(-20 f.) and takes wet climates well as long as the soil is well drained. In the hotter areas it is said that the plant melts out in full sun conditions but I can find no explanation as to what this means. I might assume it is better to give it richer soil(moisture retaining) in those areas. Use this plant in any hot border, such as that with Lavender and Sages. Let the yellows and purples play together with the silver foliage to create a classic color combination.It works as an accent, specimen, in borders or containers and massed. It attracts butterflies to your garden during the summer. An added bonus is it is both deer and rabbit resistant and drought proof.

These "Moonshine' Yarrow have been cut back and are now coming into their second bloom of the summer.

This week the America Iris Society is having its national convention here in Victoria. All the important public gardens have been prepared in the last year for the event by planting out beds of many species, hybrids and cultivars in them. With the cooler than normal spring that has effected this area of the continent most of the plants are behind their bloom schedule. One of the important species is looking lovely non the less and has some blooms. I am referring to Iris pallida and in particular the variegated forms of Iris pallida ‘Argentea Variegata’ and I.p. ‘Variegata’ (Variegated Sweet Iris).

Iris pallida Argentea Variegata has a lovely creamy quality which is a standout in any garden.

Iris pallida Argentea Variegata has a lovely creamy quality which is a standout in any garden.

Iris pallida comes from the Dalmatian Coast (former Yugoslavia) into northern Greece and up into northern Italy. It is sometimes called the Dalmatian Iris for this reason  The plant is fairly variable in flower color ranging from dark purple, lighter purple into pink and white. With the color variablity there are also several subspecies (ssp.). I.p. ssp. pallida has pale lavender flowers originates in western former Yugoslavia where it grows on the limestone cliffs there. I.p. ssp. cengialtii has darker  purple flowers with white or orange tipped beard and greener leaves and is found in north-east Italy. Iris pallida ssp. illyrica is sometimes classed as a separate species (Iris illyrica) and the issue at this point is unresolved. It has mid purple flowers and is found in its namesake, ancient Illyrica (northern Dalmatian coast). I.p. ssp. pseudopallida comes from the southern Dalmatian coast. There is  another subspecies that is known as I.p. ssp. musulmanica which I can not find any information about.

Iris pallida has unmistakable grape scented blossoms  which delights and excites the nose and is reminds many of us of our youth.

Iris pallida has unmistakable grape scented blossoms which delights and excites the nose and is reminds many of us of our youth.

I worked for many years in the wholesale area of horticulture and during that time was able to observe many plants over a long time in different conditions. Variegated Sweet Iris was imported into Canada by the perennial grower I worked for and I could compare it to many other Iris species, cultivars and hybrids at the time. Not only was I.p. ‘Argentea Variegata’ brought in but the golden variegated (‘Aureo Variegata’) form was brought in. It was clear at that time that I.p. ‘Argentea Variegata’ was the better form, is stronger growing an is less prone to disease in the wet winters we have here. This may be the reason that I.p. ‘Aureo Variegata’ is not seen and probably not sold in this area any more.

The foliage of the Variegated Sweet Iris is distinct and beautiful

There is another variegated Sweet Iris which is often mixed up with Iris pallida  ‘Argentea Variegata’ and it is I.pallida ‘ Variegata’. It is hard to tell them apart at a glance but Iris pallida ‘Variegata’ is much whiter and does not get the creamy- buttery tones in its leaves. It is also said that it is more vigorous but I can not say this is true as I have not seen the plant growing over a period of time to say for sure.I feel it is likely these plants are much mixed up in trade and often mis-labeled for each other.

This I believe is Iris pallida 'Variegata', as you can see there is no real buttery coloring in the foliage. Note all the pictures in this article where taken on the same day in one garden.

We are fortunate that Iris pallida ‘Argentea Variegata’ is much easier to obtain today and is an easy plant to grow in our gardens. It needs a bright location with full sun to part shade to bring out its best qualities. As with all rhizome producing Iris it is important to plant them very shallowly.  It likes very good drainage with humus rich soil, this is particularly important if you live in areas of high humidity or have to deal with wet winter like we have here. Good air circulation is a good idea as this will help dispel any fungus which might be lurking about. You will see signs of fungus with leaf spotting and greyish discoloration along the blade edges.  Keeping the area clean and removing spent leaves is also important for the same reason.

Iris pallida and its forms are reliably hardy to zone 5 or -23 c. (-2o f.) and I have read that they can be pushed to even colder zones if they are well protected. These plants grow 60 cm. (24 in.) high and about 30 cm. (12 in.) wide. Variegated Sweet Iris are specimen plants which do not need competition in the garden so keep other plants at a distance to show them off. They definitely can be used as an accent and make the most impact mass planted. They can also be used in containers and are most often seen in perennial borders.

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.

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.

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.

There are many plants that just give me the feeling that they have been in gardens for a long time. Plants which are some how familiar when you first see them but you can not think of what it is in that moment. One such plant for me is Kerria japonica (Kerria) which seems sold but was so new to me. Kerria is closely related to the Raspberries (Rubus) on my youth and the stems and flowers are similar.

Kerria japonica 'Pleniflora', the double form is most commonly in gardens.

Kerria japonica 'Pleniflora', the double form is most commonly in gardens.

Kerria japonica was a confused plant when it was introduced by Carl Peter Thunberg in 1776 and was mis-classified as being a member of the Tilaceae (Linden) family. This happened because the sample which was sent back by him not being complete, the specimen was also the double form ‘Pleniflora’ (Yae Yamabuki). On top of the naming problem was the fact that the plant does not come from Japan originally but was brought in from China as an ornamental shrub for gardens in ancient times. In Japan the single flowered Yamabuki (Mountain Spray) has naturalized and become part of the culture as seen in paintings, poetry and other forms of writing. We know that Yamabuki has been in Japan a very long time as the 11th century novel ‘The Tale of Genji’  mentions the plant numerous times.

The more common Kerria japonica 'Pleniflora' on the upper right and on the lower left is the single type.

It was William Kerr who in 1804 sent a living specimen of the single flowered plant back to the Royal Botanical Garden at Kew in England It was there that Kerria japonica  became recognized as being a seperate member of the Rosaceae family. For this reason the plant is now named Kerria to commemorate Kerr.

This unusual double flowered form of Kerria japonica 'Pleniflora' is found at Esquimalt Gorge Park.

William Kerr (1779-1814) was a gardener who was born in Hawick on the Scottish Borders and came to garden at Kew. There he was noticed by Sir Joseph Banks who was in charge of sending collectors and explorers throughout the world to bring back plant, animal and geological specimens to be studied and be classified in England. Banks instructed Kerr and then dispatched him to China in 1803 where he was posted at Guangzhou for 8 years. While Kerr was not allowed to travel in China he sent many important plants back from his location which was a port not far from Macao. During the time that he was posted in China it is believed that he became an opium addict and by the time he was re-posted to Colombo, Ceylon(Sri Lanka) in 1812 he was quite ill. In Columbo he was the supervisor of the gardens as Slave Island and at King House.  Kerr is considered to be the first professional of plant hunters which have changed gardening as we know it today.

Kerria japonica 'Variegata' (Picta') has single flowers and  green leaves which are delicately edged in cream. This plant can been seen at Finnerty Gardens.

 Kerria japonica is interesting in that the most vigorous form is ‘Pleniflora’ which grows into impressive multi-stemmed clumps. Another thing that stands out for this plant is the beauty of them during the period when they are without leaves, what I am referring to is the bright green stems they have and how they almost glow in the gloomy winter and earliest spring period.

The bright green stems of Kerria japonica put on a show during the drab winter months here.

Kerria is an easy plant to grow and is easily placed in most gardens. Kerria japonica like filtered sun as its blooms will completely wash out in too much sun. The best locations are under deciduous trees. The like any soil which has average moisture content and will tolerate a drier location when it is established. As you see these plants can become dense clumps, fortunately they are easily pruned after flowers. cut stems by 1/3 to 1/2 or remove them from the base as you would for Rubus(Raspberry) which they are closely related to.

This single flowered Kerria japonica is seen amoungst the mixed perennial and shrub border at Government House.

 Kerria japonica grow from .9 to 1.8 m (3-6 ft.) tall and about as wide, it has strongly ascending branches. It tolerated temperature down to -15 c. (5 f.) and still bloom very well. Give this plant protection from cold winter winds and late frost pockets as this can damage the flower production and makes them smaller and less in quantity.  the plant can be used in many ways, as an informal border, mass planted in mixed deciduous borders and for early spring interest. With the right placement it is a specimen or more usually an accent plant. The Victorian feeling this plant gives off makes this plant an excellent inclusion in heritage and period themed gardens.

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.

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

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.

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.

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.

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 Governemnt 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.

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.

When I went to work for a large wholesale perennial grower I was surprised by the diversity of material that was sold. They wanted to extend their sales season by selling not only perennials but include other related plant material such as Heather, herbs, small shrubs and in the earliest spring small bulb which you could buy in bloom at the grocer. Within the bulbs sold there were Crocus, small Daffodils, Snowdrops and Iris. The Reticulated Iris (Iris reticulata) were a brilliant blue and always sold out quickly.

The classic Iris reticulata (Reticulated Iris) ia a welcome shot of brilliant blue in the garden.

Reticulated Iris are in a subgenus Hermodactyloides which include other closely related species. They are all bulbous with netted tunics(coverings), which is where the latin name ‘reticulata’ comes from meaning netted or networked. All of the species originate in western Asia ranging from Turkey south through Lebanon through into Iraq and Iran, to the east into the Caucasus and Transcaucasia and into the former USSR.  They live in areas high in areas just below the snow line down into the lower mountain meadows and on to rocky hillside where the water runs off and they bake in the summer heat while they are dormant like many of famous bulbous plants of the area.

Iris "George' is a standout form ith its rich coloring.

There are several color forms of Iris reticulata ranging from the almost  icy white ‘Natascha’ through the light blue ‘Cantab’ into the violet ‘Lovely Liza’ and into deep purple  of ‘George’ and ‘Purple Gem’. Other species are sometimes seen in collections but are harder to find at garden centers. Here in Victoria we have a thriving, large garden community as well as many people who are interested in alpine gardens, it makes it possible to see a wider range of Reticulated Iris forms.

The exotic colored Iris 'Katherine Hodgkin' has wonderfully reticulated petals.

Several species have added their coloring and petal form to new hybrids in the Reticulated Iris group. One of the more spectacular of these is Iris ‘Katherine Hodgkin’ is a cross of Iris winogradowii with its pale yellow flowers and Iris histrioides which is pale blue. Iris histrioides  and histrio, both blue play important roles in new crosses that are being made, the both have similarly narrow petals and blue coloring. The markings on these species tends to be dark blue with little yellow seen if at all.

Iris reticulata "Alida' has a distinct solid pale blue coloring with a dash of lemon in its throat.

I am fortunate that every year at this time I can go to a grocer and buy a tiny pot with several Iris reticulata bulbs blooming in it, enjoy the flowers then plant them out in the garden. We are also fortunate that these plants are undemanding and give us such joy at this time of the year. the most important thing Reticulated Iris need is well-drained soil and a situation where they can dry out during their summer dormancy, this can be created by planting them on a slope or giving them extra gritty soil. Plant the bulbs 10-12 cm. (4-5 in.) deep and about 3 cm.(1 in.) apart.  They grow  1-15 cm. (4-6 in.) tall. they are quite hardy and rate zones 5 -29 c.(-20 f.)through 9. With extra mulch it is likely that they can survive even colder locations.

Tough Reticulated Iris flowers are not effected by winter freezes or snow piled up around them.

Tough Reticulated Iris flowers are not effected by winter freezes or snow piled up around them.

These are small plants that usually produce 1 to 2 flowers per bulb. Mass planting is the best way to display these Reticulated Iris. They are most often seen in container plantings, alpine gardens or rock gardens. Although they are tiny in statue Reticulated Iris are good cut flowers and have an unusual, delicate violet-like fragrance. They can be grown from seed but this is a slow process as it takes about 5 years to produce a flowering bulb. If they are in a favorable place the bulbs can be divided to thin the bulbs out every 2 years. The new bulbs can be moved to other places or massed where they are. One problem we have here are slugs which eat the tender flowers, so remember this when choosing a site for these tiny gems.

The slug damage to this Iris danfordiae makes it all most unrecognizable.
