235. Red-osier Dogwood

1/4/2015

0 Comments

 
The few Red Osier Dogwoods that we have on Leaning Oaks are along the vernal wetland, in the shadiest, moist part of the ravine. The dense shade makes them difficult to photograph in the entanglement!

Cornus stolonifera has bright, beautiful red  (rarely yellow)stems that make it a great shrub to have in a garden for winter colour. The white flowers are in small flat-topped bunches, followed by blue-tinged  white berries (drupes) that hang in clusters.  Red Osier Dogwood is so named because the twigs are used to make baskets.  

The bright red stem colour is best on younger shoots and gardens often prune heavily to control the height, increase the branching and maintain shoot colour. A number of named forms of this shrub are available including a dwarf selection. Hardwood cuttings are easily rooted in the late fall after leaves have dropped.

225. Himalayan Cotoneaster

12/3/2014

Himalayan Cotoneaster, also known as Khasia Berry, is an naturalised  introduced shrub here at Leaning Oaks.  For the most part, it goes largely unnoticed on a thin soiled, dry slope in part shade.  This year however, the cold snap has come at exactly the right time to catch the foliage at the point of turning and the leaves have turned scarlet, making it stand out like a beacon in the woods. ( Cotoneaster simonsii) is native to the Himalayan mountains of India, Bhutan and Nepal and high elevations of Myanmar.  It is sometimes used as hedging material and grown for its dense growth and scarlet berries.  I have never seen it become an aggressive weed here, but it is considered such in some other places, particularly in Australia.

191. Red Huckleberry

Picture
This attractive shrub is scattered throughout Leaning Oaks. Almost every one of them is perched on a decaying stump or log, which seems to be the best habitat for this species, particularly on the drier side of Vancouver Island. The graceful fern-like growth gives the impression of an evergreen because the stems are green and twiggy, but the species is, in fact, deciduous.   Unlike most Vacciniums, the berries ripen a bright red instead of the usual blue, purple or black.  They  are sought after by birds and mammals, including humans. Red Huckleberry is slow picking because of their small size but they make excellent pies and jellies. 

At Leaning Oaks the recent series of dry summers has hit many of our  Vaccinium parvifolium quite hard.  The largest individuals have died back, or in some cases, they have succumbed.  There has been some recruitment as well, including a handsome specimen on a log that forms one of the edges to our pond.

141. Black Raspberry

Black Raspberry, or Blackcap is a native shrub that grows long arching stems with a raspberry-like dark purple berry for fruit.  The lone plant here at Leaning Oaks grows on the soil disturbed by an the up -rooted tree. The species is usually associated with disturbance. The fruiting stems are two years old when they bear fruit and then they usually die.
The berry is very tasty, but sadly, we don't have enough Rubus leucodermis to get a good feed.   Other common English names include White-stemmed Raspberry, Western Raspberry or Blue Raspberry.

136. Twinflower

Twinflower is a creeping groundcover most often found in shade.  Technically a shrub, Twinflower is in the honeysuckle family.  The pale pink flowers are found in pairs and look like tiny lampshades growing on the forest floor.  An evening walk in the woods where Linnea borealis grows is a treat, since thats when the plant produces its perfume most strongly.

The mat of shiny evergreen foliage is a great foil to the pale pink flowers. It is difficult to tell where the plant stops and starts on the mossy forest floor, there are records of stems growing for more than 10 meters!  Twinflower cuttings root easily, and this is a great groundcover for the garden in moist shade.

133. Oceanspray

The billowy clouds of cream coloured oceanspray or  Holodiscus discolor  fill the air with a faint honey perfume and provide multitudes of bees and other insects food and nectar. The blooms that evoke the descriptor of oceanspray start about mid-June until the first week in July. The shrubs grow well...almost too well in open places, particularly with a bit of moisture. 

This shrub is also known as ironwood -the older wood is truly hard as nails and was used as such. Heating it over a fire made it even tougher. Local aboriginal groups including the Saanich and Cowichan used the wood for spears, building material, halibut hooks and knitting needles.

119. Nootka Rose

Nootka Rose (Rosa nutkana var. nutkana ) is in full bloom right now and the smell of the flowers is easily detectable when passing a shrub, especially in the evening.  Unlike most other roses, Nootka Rose is detectable by one's nose even when its not in bloom, since the foliage has a spicy metallic smell.  The smell always reminds me of childhood bike rides, often at the very end of the day - pushing way past the  "be home before dark" curfew.  The swampy section of Arbutus Road on the north end of Salt Spring Island was detectable by the aromatic foliage of the Nootka Rose -and it signified that the next driveway to the right was home. 
The flowers of this rose are significantly larger than the flowers of 111. Baldhip Rose, and it grows in much damper locations. Here at Leaning Oaks it is restricted to the very lowest point on the property.

In winter, especially in full sun locations, the fruiting bodies or hips are very showy.  Rose hip pie is a delicious, but the need to make sure the outer hip is used but all of the irritating hairy seeds are avoided make it a somewhat labour intensive dessert.

111. Baldhip Rose

Baldhip Rose is the commonest wild rose on the property at Leaning Oaks.  It is unusual for a rose in that is a shade tolerant species.  Most roses retain the sepal crown on the bottom of the fruit (in the same way that an apple does),  but this species drops this appendage and the small pear shaped fruit is smooth.  The latin name,  Rosa gymnocarpa refers to this;  gymnocarpa means "naked fruit".  The leaves can be used to make a rose tea.

109. Trailing Blackberry

5/22/2014

Trailing Blackberry is both beloved and cursed, depending on where an individual plant grows and the nature of your interaction with it.  The fruit is wonderful, and this species has been used in breeding programs to produced very flavourful blackberries.  In addition, it is one of the parents of the hybrid loganberry, marionberry and boysenberry.  The foliage is also very flavourful and is a very good leaf to steep to make blackberry tea.  On the other hand, it can be a rapidly growing weed in the garden, fully capable of creeping along the ground  or scrambling over shrubs and perennials for several meters in a single growing season.  Branch tips often root, and a neglected vine quickly can turn into a big job.  The stems are thorny, so pulling without gloves usually gets you a hand full of thorns.  Summer strolls in flip-flops or sandals is an excellent way to find this plant, and it becomes painfully obvious why one alternative name is "ankle saw". Rubus ursinus ssp. macropetalus  is dioecious,  that is males and females are on separate plants.  Pity that most of the plants here at Leaning Oaks are male, and therefore don't produce fruit.  Alternate common names are Pacific Blackberry, Dewberry, Douglas Berry and California Blackberry.  I have several other names for it, best not repeated here.

98. Orange Honeysuckle or Western Trumpet

Picture
Orange Honeysuckle (Lonicera ciliosa) is one of two species of Lonicera that we have at Leaning Oaks.  It is the earlier blooming of the two.  Unlike moth pollinated honeysuckles, our native honeysuckle vines are pollinated by hummingbirds, and their showy flowers and large nectaries (but no perfume) are typical of hummingbird pollinated flowers.  It is one of the few native vines in our area, and can climb up into the canopy of small trees.  Here they grow up Garry Oaks and small Douglas-fir trees.
