632-001D4 Corokia cotoneaster
Sun Zones 8, 9, 10 Yellow flowers
Sometimes Corokia cotoneaster looks like a shrub that has lost most of its leaves. The new stems in autumn and winter look especially bare, while deep in the core of the shrub are numerous small oblong leaves that are not readily evident at first glance. We grew this with no water on a south-facing slope. The gray to gray black stems are very attractive, especially when the tiny yellow flowers are in bloom. Late spring. bloom 8 ft. x 8 ft.
632-004D4 Corokia virgata 'Sunsprite' (x)
Part Shade Zones 8, 9 Yellow flowers
Corokia x virgata 'Sunsprite' was found and cleverly named by our friends at Cistus Nursery. As its name suggests, this evergreen shrub is compact and slow-growing. In full sun, the leaves are almost platinum blond but in part shade they keep their bright yellow color. Individual leaves are lance-shaped and come to a distinct point. Grey stems covered in tiny hairs are fully visible through the sparse foliage. Corokia grow best in lean soils that are well-drained. They resent cold, wet winters in heavy clay.

632-002-1 Corokia x virgata 'Sunsplash'
Sun Zones 8, 9, 10 Yellow flowers
For several years, we had enjoyed this open-habited evergreen shrub with its small, yellow splashed leaves showing cream and green highlights. Its see-through quality had combined nicely with other more densely foliaged shrubs in the background. We lost Corokia `Sunsplash' in the garden during our record cold December 2009, we miss it so much we are replacing it. Late spring. bloom 5 ft. x 3 ft.
445-001D4 Correa alba 'Ivory Bells'

572-001-1 Corylopsis pauciflora ( Buttercup winter hazel )
Sun, Part Shade Zones 6, 7, 8, 9 Pale Yellow flowers
At the end of winter, we await the arrival of warm colors in our garden. Corylopsis pauciflora provides just that. Our mature specimen produces an immense number of flowers. In addition to their welcome color, they also bring a delicate fragrance. This densely branched, medium-sized shrub was introduced to the West from the Orient by Robert Fortune in the 1860's. It has been a mainstay in large borders and winter gardens ever since. In the early spring, the emerging leaves are tinged with bronze. As they unfold, their ribbed pattern becomes pronounced, raying out on either side of their central veins. As a result, even though its leaves are small, as its botanical name suggests, the shrub offers textural interest throughout the season until it drops its yellowing leaves in the fall. Early to midspring. bloom 5 ft. x 8 ft.
572-002D4 Corylopsis sinensis var. calvescens f. veitchiana
Sun, Part Shade Zones 5, 6, 7, 8, 9 Lemon-yellow flowers
Coryopsis sinensis var. calvescens f. veitchiana plays an important role in our early spring garden when its 3-inch racemes dangle fragrant flowers from its leafless branches. For sheer flower-power, there are few spring-blooming shrubs that can compare. When the rounded and ribbed leaves do appear they are often tinged with bronze. As they mature they turn dark green above and have a blue-green cast underneath. This is a large shrub with sinuous spreading branches. The bark is cinnamon in color with occasional mottling. As the botanical name indicates, the shrub is from China. Early to Midspring. bloom 12 ft. x 8 ft.
095-001 Cosmos atrosanguineus ( Chocolate Cosmos )

Sun Zones 5, 6, 7, 8 Yellow Green flowers
Cotinus coggygria 'Nordine' was developed and selected by the Morton Arboretum in Illinois. On our hillside its reliably purple foliage makes this showy small tree visible from afar. The leaves are rounded, measuring up to eight inches long. In the autumn, their dramatic color change to shades of orange and yellow are a sight to behold. In summer, however, when the tree is smothered with its "smoke" of small airy flowers, it is perhaps the most noticeable. June bloom 12-15 ft. x 12/15 ft.

543-003-1 Cotinus coggygria 'Royal Purple' ( Smoke tree )
Sun, Part Shade Zones 5, 6, 7, 8, 9 Purple/Yellow flowers
We use this dark-purple foliaged tree as the back drop for one of our lavendar walks. There, its dark foliage shows off the flowers of the lavenders, spiraeas, and old world salvias. Nearby gold foliaged Spiraea 'Ogon' contrasts sharply with 'Royal Purple' and keeps this area from becoming too gloomy. We keep the Cotinus c. `Royal Purple' in scale by regularly cutting it back in the late winter. By doing so, we maintain a broad but 10- to 12-foot tree that anchors this border. The summer inflorescences are in loose terminal panicles which rise above the foliage. From a distance, the cloud of tiny flowers resemble a haze of smoke which is the origin of the common name Smoke tree. May to July. bloom Up to 20 ft. x 15 ft.
543-001-1 Cotinus coggyrgia 'Velvet Cloak' ( Smoke tree )
Sun, Part Shade Zones 5, 6, 7, 8, 9 smoke-like panicles flowers
We have come to rely on this small tree to create drama in our lower garden. We keep it stooled so that the majority of its dark foliage is low enough to contrast nicely with the golden leaved plants that we have introduced there. Cotinus coggyrgia 'Velvet Cloak' has plume-like, terminal panicles in the summer that give the plant its "smoke-like" halo that is referred to in its common name. Its rounded, 3-inch leaves are a rich purple with red highlights during the summer. As the temperatures begin to cool in the autumn, the leaves take on smouldering red tones. Summer. bloom 15 ft. x 12 ft.

543-004D4 Cotinus 'Grace'
Sun Zones 4, 5, 6, 7, 8 Pink flowers
Cotinus 'Grace' is a hybrid between Cotinus obovatus and C. coggygria 'Velvet Cloak' and was created by Peter Dummer of Hillier Nursery in the UK. The result is a large shrub or small tree with bright wine-red young leaves that turn blue green as they mature and then take on vivid colors in the autumn. It is fast growing but can be kept in scale for a smaller garden by giving it a hard prune at the end of winter. When the large airy panicles of flowers appear, the effect is riveting. A Great Plant Picks selection. Summer. bloom 10-15 ft.
543-004-1 Cotinus 'Grace'
Sun Zones 5, 6, 7, 8 Reddish flowers
The brilliant deep red purple, rounded leaves of Cotinus 'Grace' look bright red with the sun shining through them. Older foliage turns dark wine red and then becomes suffused with green.

317-005-1 Cotoneaster horizontalis ( Rockspray )
Sun Zones 4, 5, 6, 7, 8 Pink/White flowers
After 15 years in our garden, our specimen of Cotoneaster horizonatlis is much larger than usually stated in the literature. By now it is 5-feet tall and 7-feet wide. Its stiff branches are arranged in a "herring-bone" patern which is especially apparent in the winter after the dark leaves have fallen. These branches do indeed grow horizontally as the name suggests. They also grow downward at their ends and so make a dense groundcovering shrub. Toward autumn, the branches are laden with bright and glossy round fruits that persist into December. Our shrub grows at the base of a fastigiate copper beech and it anchors and connects that tree to the rest of the border. Late spring. bloom 3 ft. x 5 ft.
317-002D4 Cotoneaster nitidus (distichus)
Sun, Part Shade Zones 7, 8 White Blushed Pink flowers
Cotoneaster nitidus anchors our fuchsia path. We have pruned it to create an open, upright, fan-shaped shrub that is always dynamic. From late spring to early summer, the countless small flowers are abuzz with the hum of honeybees. At high summer, the tall arching branches form a filigree of leaves against the sky. By the late summer, brilliant red fruits echo the red in the Christmas colored fuchsias nearby. These fruits persist into the winter when the plant becomes a haven for wildlife. Early summer bloom 8 ft. x 12 ft.
023-001-1 Crambe cordifolia
Sun Zones 6, 7, 8, 9 White flowers
Just as the spring perennials are finishing up in the Dry Border and the Buddleias are setting their bloom, the massive leaves of Crambe cordifolia unfold from a huge purple rootstock. Soon, clouds of tiny white flowers appear on 8-foot stems. The effect is one of a giant baby's breath. The flowers are honeyed at first and become less sweet with age. Spring. bloom 8 ft. x 5 ft.

Later in the year they tend to dull with age. It seems quite happy in the shady end of our Point Garden against the silvery backdrop of the sunny end. Early summer. bloom 3 ft. x 2.5 ft.
547-011 Cyclamen coum 'Silver Form'
Shade, Part Shade Zones 5, 6, 7, 8, 9 White to Pink flowers
We select seedlings of Cyclamen coum 'Silver Form' from our garden where we look for leaves that are almost entirely silver on their upper surfaces and have a fine line of contrasting green.around their edges. This cyclamen goes entirely dormant during the summer but, by late autumn, we begin to see the rounded leaves seemingly resting flat on the ground. These leaves persist until summer heat begins. The dainty flowers which often emerge with the leaves are short-lived. They are held on short stems and their up-flung petals make them resemble shooting stars. We grow this cyclamen under shade trees, conifers, even under eaves where they seem quite content to follow their own yearly rhythm. Winter to early spring. bloom 2-3 in.
547-001 Cyclamen hederifolium
Shade, Part Shade Zones (7), 8, 9 Pink flowers
The leaves of Cyclamen hederifolium are marbled in light and dark green. They are somewhat triangular in shape, with wavy edges and purple reverses.

547-007 Cyclamen hederifolium 'Silver Leafed'
Part Shade, Shade Zones 5, 6, 7, 8 Pink/Rose flowers
Our thanks to the O'Byrnes at Northwest Garden Nursery for introducing us to this selection. We lift and grow our own all-silver seedlings, selecting only the best for our customers. As with the species, the flowers of Cyclamen hederifolium 'Silver Leafed' arise just at the advent of new foliage growth (usually September in Portland, Oregon).

Cynara cardunculus is a relative of the artichoke (Cynara scolymus). The cardoons are massive clumping perennials with arching, gray, deeply cut basal foliage and towering bloom spikes. The flower heads resemble prickly artichokes with intense purple flowers that draw bees & hummingbirds alike. The plants may go into a short period of dormancy after blooming. Cut back the spent bloom spike and they will grow new leaves which they will carry through the winter. A Great Plant Picks selection. Summer. bloom 12 ft. x 5 ft.
