A Blizard of Blossoms

Some plants I see and fall in love with instantly and want to get one…when reality sets I know this is impossible as I have no spot to put it. I will forget about the plant and later stumble on it in other places and remember all over again how beautiful it is. Such is the case with Styrax japonius(a) (Japanese Snowbell tree), its a tree which I keep stumbling on and see how wonderful it is.

The dainty scented white bells of Styrax japonicus coat the undersides of this small tree.

Styrax  is a genus of 130 species of which only a few come areas other than the tropics and several are used in garden. Styrax japonicus is the most well-known of the ornamental plants. Some tropical Styrax species are also known for giving us benzoin resin which is exuded from piercing the bark and collecting the dried substance. The resin has been used since antiquity in perfumes, incense and medicines(tincture of Benzoin).

The Japanese Snowbell is a small layered tree with elegant leaves and flowers.

Styrax japonicus come from a fairly wide area of Asia from Korea into China and Japan. Japanese Snowbell was first described by Seibold and then re-introduced by Richard Oldham(1834-1862) in 1862 from Japan. He was employed by the Royal Botanical Gardens(Kew) and was sent to collect plants in Asia in 1861. He first collected around Nagasaki and Yokohama  (1862-3) and later in China where he died at the age of 27. He introduced no new species but his extensive herbarium collections were studied at Kew and in Leiden Germany.

Styrax japonicus 'Rosea' has the lightest pink tinge at the base of the flowers.

When Japanese Snowbell was introduced the public in the 1860s it must have made an impact on gardeners and other esteemed people as it was quickly awarded a First Class Certificate (FCC) in 1885 by The Royal Horticultural Society. In  1984 it was given another award by the same group  an AGM (Award of Merit).  These awards are made from recommendation  by a committee to the RHS council and are similar to judgements made at exhibits (based on samples, branches or plants which are viewed on one day).

Styrax japonicus are very late to color up in autumn and when they do we are rewarded with buttery yellows which fade to light reds.

Japanese Snowbell are small trees which have layered branch structures. They are often nearly as wide as they are tall. When they are in bloom the flowers coat the undersides of the tree with small drooping white bells which have a pleasing light perfume. It is best to locate these trees where they are on a slight incline so it is easy to view the flowers in bloom. The fruit produces are small drupes which look like tiny nuts and are dainty.

Tiny egg-shaped drupes are the fruit produced by Styrax japonicus.

Japanese Snowbell trees grow 6-9 m 20-30 ft.) tall and nearly as wide. They grow in full sun to dappled locations and even fairly dark areas. Like many small trees in its native habitat it is often found as an understory plant growing amoungst larger trees. It likes well-drained rich soil which is slightly acidic.These trees are surprisingly hardy and are rated as zone 5 -29 c. (-20 f.).

Styrax japonicus (Japanese Snowbell) are perfect small specimen trees for urban gardens.

Styrax japonicus can be used in a variety of ways, they are ideal for as small specimen trees, for small urban lots, patio plantings and in small groups. They are also well-known as bonsai subjects.  There are several named forms worth looking into. ‘Emerald Pagoda is a selection which is more robust with bigger flowers and leaves. ‘Pink Chimes’ has better, more pronounced color which does not fade out in heat. ‘Carillon’ is a weeping form which is said to be the same as ‘Pendula’. ‘Angryo Dwarf’ is as the name say an even shorter form. It is up to you what one you feel is the best for your situation…I have always been a sucker for pure white flowers!

Grist for your Paperbark Maple.

Autumn is known for its wonderful colors, the yellows, oranges reds and maroons add a bright splash of excitement to the coming winter season. I enjoy the many native trees in the area with their amber shades. One somewhat rare tree which should become much more widely grown is  the Paperbark Maple(Acer griseum) which has bright buttery yellow to crimson coloring. It is one of the best small specimen trees for a typical urban setting.

 

Autumn color of the Paperbark Maple some of the latest in the year for the Maple family.

The year was 1901 Paperbark Maple was introduced to Europe by way of Vietch’s Nursery.  Acer griseum is another fabulous find by Ernest (Chinese) Henry Wilson. He was on one of his many explorations for plants in China looking for the famous handkerchief tree(Davidia involucrata) which was known but not collected at that time. The area he was exploring was central China.

 

I can imagine Ernest 'Chinese' Wilson finding Acer griseum in the forest looking like this, bark glowing in the light.

 

Paperbark Maples come from central China from north-east Gansu  province traveling west into Hebei and south to Sichuan and south-west into Hunan.  The tree is found at fairly high altitudes of 1500-2000 m. (5000-6500ft.). It is one of the better but not the most famous find of the over 1500 named plants which ‘Chinese ‘ Wilson brought to horticulture during his incredible explorations.

 

The peeling 'paperbark' of Acer griseum is very beautiful throughout the year.

 

Acer griseum does not have the typical ‘maple’ shaped leaves, instead it is trifoliate. This gives it a delicate feeling as the foliage looks fine in texture. Many people are not familiar with the other leaf forms of  Maples. One similar leaved maple is the Box Elder(Acer negundo) which is extremely hardy and produces masses of seedlings making it become somewhat of a pest in many places.

 

The delicate looking trifoliate leaves of Acer griseum come to life in flaming fashion in the fall.

Acer griseum is an excellent small tree for the home and should be seen more often. One issue that has become known is the difficulty germinating the seed which is said to be between 2 and 8%. It produces a good amount of  seed but most of it has proven to be parthenocarpic. Parthenocarpic is seed which developes but is sterile. THere are now plans to make new collections of wild seed to increase the gene pool of this tree and increase the likelihood of better seed viability. Another issue is that these trees are androecious with males and hermaphrodite flower structures.

 

 

Acer griseum produces a great amount of seed but little of it is viable.

 

Acer griseum has many feature which lead it be seen as a specimen tree. It is attractive throughout the year; spring gives us delicate blooms and the flush of new leaves, summer is seen with the delicate green-blue of the leaves, autumn highlight the brilliant color late in the season and winter comes when the bark is highlighted especially with backlighting. The size of the tree is also especially appealing and works well in most garden situations whether they be in a border or by itself.

 

This wintery Acer griseum is found in Finnerty Gardens along a less traveled path where the bark is highlighted.

Acer griseum grow in full sun to part shade but not deep shade. They like fertile acidic soil which is well-drained. They need average amounts of waster and are not noted to be drought tolerant. They have few pests or disease. They can be pruned but it is rarely done except for  shaping or removal of damaged limbs and this is best done in late autumn or winter. They are slow-growing trees which can grow to 10-20 m (30-60ft). They are fairly hardy and are rated taking -20c(-4f) and higher.  Paperbark Maples are easily transplanted.

 

This Acer griseum is in the back yard of a garden in Vancouver.

 

Paperbark Maples are propagated by cuttings or by seed and are somewhat rare in nurseries. They are becoming much sought after by good landscapers and gardens are more expensive to buy than many other trees. It is a tree I recommend for the small city gardens as a specimen or accent tree.

Marveling at this Maple:

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.

The Scent of Honey in the Fall Air.

When I was in Horticulture school we learned many plants ranging from small ground covers, larger shrubs and finally to the majestic trees. Some of these plants are very overused while others are not seen enough, it all depends on how well known and in fashion they are.  One tree I learned is much more common in Vancouver than it is in Victoria and that truly is a pity. What I am referring to is the ‘Katsura’ tree (Cercidiphyllum japonicum) which has many features that it should be on most peoples lists of ‘must have’ trees.

Cercidiphyllum japonicum or 'Katsura Trees' on a rainy spring day in Vancouver.

At one time, long ago, Cercidiphyllum japonicum grew wild in a much larger area. Fossil records show Katsura trees lived in Europe and western North America during the Miocene Epoch 5 to 23 million years ago. Now They are found only in Japan and China. They are found in south central China,  particularly in north west Szechwan province where E.H. Wilson found forests of them in 1907. The trees found in China were considered to be a variety Cercidiphyllum japonicum var. sinense at one time and were said to be more tree-like.  In Japan they are found at valley bottoms where the soil is richer and there is more rainfall which these trees need.

The attractively shaped leaves is one of the most appealing aspects of 'Katsura' trees

Cercidiphyllum japonicum was introduced into cultivation in a most unusual way. Thomas Hogg  Jr(1819-1892) who owned a plant nursery with his brother James. He was appointed a U.S. Marshal by President Abraham Lincoln in 1862 and was then assigned to a diplomatic mission to Japan. While he was there, Thomas sent seeds of Cercidiphyllum japonicum to his brother  in 1865. His brther germinated them. Thomas was in Japan 10 years and also introduced several other well known plants;  Hosta ‘Thomas Hogg’  now called H. undulata var. albomarginata is probably the most famous.

Typical fall color of Cericidiphyllum japonicum found in the perennial border at Playfair park in Saanich.

Katsura trees tend to be multi trunked specimens which have strongly ascending branches. The leaves are relatively small and delicate compared to what the trunk and branches can become when these trees become more massive with age. It is intersting to note that these trees are also somewhat unusual in that they are dioecious meaning they are male or female plants.

A massive trunk of a Cercidiphyllum japonicum found in Beaconhill Park in Victoria.

In an ideal world Katsura trees grow to be enormous, Wilson found forests of trees with trunks of 2(6cm) and 3ft(90cm) widths and had regrown from their original stumps after the original trees had been harvest.  The largest one he noted was a remnant of a 17.5ft(5.33m) wide stump base. In the wild these trees can attain a height of 100ft(30m), but about half this in garden settings.  These trees are the most important source of wood  in Japan, and is used extensively for cabinetry and paneling there.

The color range of Cercidiphyllum japonicum ranges from crystal clear yellows through oranges and crimsons into plums as seen here.

As autumn approaches Katsura trees put on a display for the senses, visually they are stunning with a color range few trees can achieve. On any day you will feast your eyes on shades of clear yellow, butter, many shades of peach and apricot, and into more striking crimsons and plums. You will notice they give of a pleasant odor as the leaves turn color, some describe it as ‘honey like’ and others say it has more of a’caramel’ or ‘brown sugar’ quality. How ever you explain it, it is a pleasant surprise which many people look forward to every year.

The striking golden tones of a happy Katsura tree changing color in the fall.

Cercidiphyllum japonicum is almost a perfect tree. It is very pest free and adaptive to most locations. In a garden setting it will grow to about 50ft(15m) tall which will fit in nicely to many landscapes. It makes an excellent multi stemmed residential, commercial, golf course or park tree. One thing you must keep in mind when placing it is having an adequate supply of water during the dry months.  Plant them in deep, rich, well drained soil. They need full sun to look their best.  This tree tolerates temperature down to 20f(29c). Newly emerging leaves can be damaged by late frosts.  there are several forms now on the market worth looking into if you are interested. the weeping forms are very attractive in the right location.

The Exquisite Woodland Resident

The first gardening job I had was working for the summer at Park and Tilford  Gardens in North Vancouver. II was lucky as it was like an 4 month extension of education for me. Park And Tilford Gardens was at one time a well know distiller of the same name which was sold and turned into a shopping center on the condition that it kept the well known garden there.  The tiny space which is the garden had been neglected and then reclaimed to opened to the public.  The space is made up of 8 small themed gardens in a 3 acre site.

Magnolia sieboldii also known as the Oyama Magnolia.

It was particular famous for it’s collection of Magnolia trees. As you moved from the display garden into the the colonnade on the right side was a shrub like tree with large attractive smooth green leaves that is  now  beginning it season of bloom. This is the beautiful Magnolia sieboldii or Oyama Magnolia. It slowly blooms over a longer period than most other Magnolias which is only one of it’s many features.

Oyama Magnolia with lighter color stamens is likely to originate from Japan.

One thing that makes Magnolia siboldii attractive is that their flowers droop down so you look up into them. This downward facing flower is one of the features which shows off it’s attractive interior structure which is very primitive and found in Magnolia species.  the bizarre cone-like carpel is surrounded by many thick stamen which range from a rich dark blood red to a pale flesh color. There are both color forms in the Victoria area. The difference in stamen color tell us where the plant comes from. The plants which have the fleshy colored stamens are likely to originate in Japan(Honshu to Shikoku through to the Kyushu Islands) or southern China( Anhui, Fujian and Guangxi) and are  designated as Magnolia sieboldii subsp. japonica.  The red stamen plants come from a wider area including Korea and northern China(Manchuria) and are Magnolia sieboldii subsp. sieboldii.

The Other-worldlyMagnolia sieboldii Seedpod Still Ripening.

Oyama Magnolias are usually low multi-stemmed shrub trees which are wider than they are tall, growing 3.5m(10ft) by 4m(12ft) wide. The best placement of these trees is a elevated so the flowers are more visible. In Victoria the best location for this is most surprising, in a retail shopping center.  Look behind the Harris Green Village Shopping Center on View Street, at the bottom of the steps and going up into the shopping area there are several including a large one at the the top along the sunnier wall.  These are the pale stamen form. If you want to see the dark red form  of Magnolia sieboldii there is one in Beacon Hill Park along the stream  which runs between Goodacre and Fountain Lakes which parallel Blanchard Street. make sure you visit this species of Magnolia in the evening when it’s fragrance is most potent.

Magnolia sieboldii on View Street behind Quadra Village Shoping Center

This is one Magnolia which is a forest dweller who does not like full sun.  All the Oyama Magnolias I have ever seen have been in sites which are sheltered from midday sun which would burn their leaves.  Care must be taken whenever you plant a Magnolia as it has fleshy brittle roots which can easily break, this is the time of most danger for these trees. they like fertile, moisture retentive soil which has some humus in it. It needs adequate water during the dry season here for good growth.  Do to it’s delicate roots it is not advisable to plant underneath(the trees in the above picture are under-planted with Pacysandra, a lush ground cover). Treat this tree as a specimen in your garden as it will be loved by all who see it.

Magnolia sieboldii in Beacon Hilll Park in Early Spring.

Oyama Magnolias bloom slowly over several months, from May sometimes into early August.  They are hardy to -20c(-5f) in North America but in their native setting have been known to withstand -40c(-40f). They are rated zone 6 through 8 here.

Early, Red, Wow, Rhododendron?

In the Great Victoria we a blessed to have many parks and rural areas which we can explore, often the nearest ones are the places that are overlooked.  I had been to Dominion Brook Park near where I live several times with my sister and her son to play and explore the large safe. It was only later when I took my father to see the park that I realized what interesting plants were there.  In reading about the history of the park this is not surprising. It has one of the oldest plant collections in the area. It dates back to 1913 when it was established by the then Canadian Department of Agriculture as a demonstration arboretum and ornamental garden for the public to enjoy.

Dominion Brook Park in North Saanich.

Dominion Brook Park  still has significant collections of conifers, Hollies, Camellia and Rhododendrons which were imported from some of the most famous nurseries in the world. If you go to the park at this time and look across the main pond you will be surprised to see a fiery red Rhododendron blooming and sometimes reflected in the still water. This is one of the original Rhododendron which was brought from Arnold Arboretum by Ernest ‘Chinese’ Wilson to give to the new park. The red  Rhododendron strillgilosum is one of the species he discovered in his plant collecting trips in China which he became famous for.

 

Brillant Red Blossoms of Rhododendron strigillosum.

 

 

Rhododendron strillgilosum overlooking the pond at Dominion Brook Park.

Rhododendron strigillosum is a dramatic sight to behold at this time of the year and is a break from all the yellows, whites and other pastel colors that seem to dominate  now. The red coloring stands out from the other early blooming rhododendrons such as  sutcheunense(pink), dauricum(mauve) and moupinense(white to pale pink). the species is not too common to find and you will have to look in an specialty garden or collection. What is common are the hybrids from this strigillosum which bear definite resemblance to the parent and several have become famous in their own right.  Etta Burrow, Grace Seabrook, Malahat, and Taurus are but a few which are commonly seen in gardens in this area.

Rhododendron strigillosum is Loaded with Blooms.

Rhododendron stigillosum is easy to recognize as is a large  rounded shrub or small tree which can grow to 25ft in a suitable location. It has long elliptical leaves with edges that are often rolled under. Looking more closely at the leaves, bristles which are reddish are seen coating it. These bristles are most noticeable on new growth  as well as on the branches.  This plant is found in the provinces of Sichaun and Yunnan, China at 7 to 11,00 ft( 2100-3400 m). It was introduced to Arnold Arboretum by E.H. Wilson in 1904.  It was award  an AM (Award of Merit) in 1925.

 

Rhododendron strigillosum in Finnerty Gardens.

Rhododendron strigillosum and it’s hybrids are all easy to grow. Like all rhodos’ they like rich well drained soil with some extra organic material added early each year. Rhododendrons are shallow rooted therefore it is especially important that they are watered throughout the year. Next years flower buds are being set in late summer when we often have an extended dry period, if watering is neglected it will effect blooming the following spring!   Rhododendron are usually forest dwellers and show their displeasure at being exposed to too much sun by having yellowed leaves, dappled conditions are prefered.  These are fairly hardy plants and tolerate temperatures down to  5-14f (-10 to -15c). for short periods.

A Very Un-Dogwood Like Bloom.

I Remember when I was going college I walked every day to get the the bus. I used this time to learn the 300 or so plants which were required  for me to pass the program. Fortunately in the few blocks to the bus stop there were many plants on the list.  As the seasons progressed I saw the changes that occurred with each of the plants I studied from fall, through winter and into spring. I would never have noticed the bushy shrub-like tree which I stood in front of every morning until it burst into bloom at this time of the year.  To my delight it was a Cornus mas or Cornelian Cherry Dogwood which produced a spectacular golden display before most other plants are in bloom.  I never saw another one until….

Cornelian Cherry Dogwood.

This tree is in the Doris Page Winter Garden at Glendale Gardens

Bejeweled Branches of Cornelian Cherry Dogwood Flowers

I regularly visit the Glendale Gardens and found several in bloom, WOW is all I can say. This year since I knew I would write about Cornus mas I have been on the hunt for others and have struck several golde(en) bonanzas. I looked in the usual places and was not disappointed, two at Government House and two at Finnerty Gardens.

A Huge Cornelian Cherry Dogwood on corner of Trutch St. and Fairfield Rd.

The real surprise was on the way to Government House driving along Fairfield Road. I saw an incredible huge example at the corner of Trutch Street. and Fairfield Road. I am so glad to find a Cornus mas that is on a street side instead of of a park or fancy garden. This is a highly traveled site that anyone can go by and enjoy the beauty of this tree.

This wonderful  plant comes from central and southern Europe and also is found in Western Asia where its large ‘cherry-like’ fruit is used  for making  jams and sauces. In Armenia the fruit is added to Vodka to flavor it.  The deep red ripe fruit is an oblong drupe which is up to 3/4in.  long by 1/2in wide and contains a large stone. Several Cornelian Cherry Dogwood cultivars have been selected with unusually large fruit for commercial production.

Cornus mas clad in its Summer Suit at Glendale Gardens.

The best thing about Cornus mas is that it is easy to grow and will fit into many planting schemes. It works well as a  specimen or in a winter garden, in a natural or woodland setting. As it has a small stature of no more than 25ft by 15ft it will fit well into many small urban gardens. It also looks good in small feature groups or in a mixed shrub border where its bright flowers will standout from the dark background.

Attractive mid-green foliage of Cornus mas.

It is the least fussy of the large Cornus (Dogwood trees) and will tolerate any soil from dry to quite wet. It grows best in full sun to part shade which is especially needed in hot drier climates as the leaves are thin and loose moisture easily. Cornus mas plants take pruning very well and is often shaped into a several stemmed small tree which helps to show off the attractive flaking bark.

Well pruned Cornus mas showing the attractive bark.

There have been several well known forms of Cornelian Cherry Dogwoods which may be available in your area.  ‘Aurea’ with golden leaves, ‘Variegata’ which is edged in cream and ‘Elegantissim’ with pink or golden highlights are some of the foliage forms. There are also golden and white fruited forms known. On top of these there  are  pyrimidal, dwarf and extremely cold hardy (‘Ukraine’ tolerates -30f.) selections available. Zones 5 through 8.

A Cornucopia of Colorful Berries

A plant species I mostly find boring is Cotoneaster. They are one of the most commonly overused group of plants seen as groundcovers, hedges and often in utility mass plantings. Some Cotoneasters are beautiful in their own right. The Willowleaf cotoneaster (Cotoneaster salicifolius var. floccosus) is such a plant that is stunning in the correct setting. In Victoria this location would be at Government House.

Looking down from the top of the Ballroom Terrace Garden

The most fantastic view from the building is out the of the ballroom overlooking a steep slope called the Ballroom Terrace Garden.

Most of the year these Willowleaf Cotoneasters are merely a green backdrop which other more delicate plantings are the highlights. It is true that these Conoteasters have masses of cream 5 petal flowers in May-June, but no one is likely to notice with the abundance of other plants at their peak of show.

The Cotoneaster on left acts as a backdrop to the Erysimium 'Bowles Mauve'.

It is later when the garden goes dormant and the days are gray that a person sees these plants in their glory, in full fruit with their glossy roughly textured dark green willow-shaped leaves undamaged by the worst of winter weather.

January 16 2009 after a deep winter freeze and heavy winds.

The only damage is a slight wine tinge to the leaves and deepening of the berry color which is typical for this plant.

Typical berry color from late October 2006

Indeed the berries are the glory of this shrub and set it apart from others at this time of the year. The berries are dense and seem to stay firmly on the bush. After the storms I saw little evidence of many on the ground. Branches of this small tree would make an attractive addition to decorate inside I think.

Brightly berried Willowleaf Cotoneasters glow in the winter murkiness.

it is unfortunate the place you are likely to see this plant is in an apartment complex where it often is dwarfed by the building and never pruned to show what a lovely form it can have. As you can see it forms a small multi trunk tree or shrub which grows to no more than 4 M. (12ft.) which would be on the tall side, and a spread of up to 3M (10ft). Willowleaf Cotoneaster has an arching habit of growth.

Cotoneasters are unfussy plants to grow, they prefer well drain, loose soil. They are their best in full sun so they can produce the best crops of flowers and berries later. It has a fairly rapid rate of growth at 60 to 90cm(12-18in.) per year and is easily pruned to keep it in shape and size. It grows in plant zones 6 though 8 and tolerates low temperature of -20c(-4F).

A  steep slope is an excellent use of this type of plant.  Another site might be along the edge of a of shrub border or where an area is more natural or in a mixed shrub border where the berries will shine in the winter months. Cotoneasters are often used in mass plantings which when maintained properly are effective.

I would suggest choosing carefully when getting one of these plants as they vary in quantity of berries, some have fewer. It might be a good idea to buy in the fall when you will see what kind of crop is produced. If you want to grow one for yourself I would suggest taking a cutting from a bush you know produces lots of berries. Softwood cuttings are taken in during the first flush of growth or slightly later on non blooming wood.
