Royal Grevillea is one of the most handsome shrubs that we can grow in our climate. Native to the highest elevation in Australia and then down to the middle elevations this species has been grown in our climate successfully for many decades. Large, long gray foliage is handsome year round and a great backdrop to the masses of orange pendulous flowers which are most prolific during winter. Loved by hummingbirds – Anna’s will stake out this shrub as one of the few sources of nectar during winter. Full sun to light shade in average soil with light, consistent water to establish. Avoid baking hot locations as this plant forms and sets its flower buds in late spring and summer and they hold until the cool of autumn arrives to open. If this plant becomes too hot or stressed it can abort these flower buds diminishing the following seasons display. So, an average position away from reflected heat produces the best blooming. Very good performance in cold rural gardens, enduring 5ºF with no issue. Very large growing to 12′ x 12′ and sometimes larger with time. May be pruned hard in early spring to both limit the overall size but to increase density and blooming wood. Great performance at the Oregon coast and in Puget Sound as well as the coast range and Cascade foothills. In the Willamette Valley the hybrids ‘Neil Bell’, ‘Octopinky’, ‘Poorinda Queen’ and the species G. Juniperina do not abort their flower buds in the hottest weather- and seem to perform more satisfactorily. Moderately deer resistant. Long lived. This form is from the University of British Columbia.
Wavy Leaf Silk Tassel is a beautiful winter blooming evergreen shrub native to the Oregon coast from Lincoln county south to Santa Barbara county California. Amazing 1′ long silver gray tassels from late fall last through winter. Large shrubs have the appearance of a chandelier. Tassels dry and abort the plant by late spring, then its just a clean evergreen To 12′ x 12′ for well drained soil in full sun with good air circulation. Some leaf burn in the coldest winters. Eventually it can become a multi-trunked tree. Extremely drought tolerant when established, never needing supplemental summer water. Prune AFTER flowering. Excellent espalier. Spectacular in full bloom– which lasts for two months in mid-winter. Full sun to quite a bit of overhead shade. Avoid strong subfreezing east wind. Oregon native plant.
Why, its not a Cotoneaster at all, in fact Corokia is a wildly architectural shrub and evolved its twisted zigzagging stems (the official term is divaricating) and tiny leaves to fend off grazing by giant Moa birds in New Zealand. The birds are now extinct and we are left with this shrub as an evolutionary natural bonsai. To 5′ tall and 3′ wide in 7 years. Average to enriched soil. Full sun to part shade. Flowers are more profuse in sun. Regular water. Great container plant. The yellow flowers in May are often followed by red /orange berries that don’t last long. I assume the brilliant color draws birds. Established plants accept both regular irrigation as well as summer drought. Irrigation encourages growth. Left to contend with summer drought the plant is naturally smaller. Cold hardy to 5ºF or lower for brief periods. Excellent landscape or garden plant that imparts a haze on the landscape from a distance but thrills with up close views of the zig zagging branches and tiny black shovel shaped leaves. Excellent long lived container subject and will thrive even with constricted roots. We love this shrub for its silvery winter appearance in containers and in container combinations. Mix with Sasanqua Camellias and Western Blue Fescue (Festuca californica) for months long entertainment. Seldom bothered by deer.
This is a hardy shrub in a genus that is known for being decidedly tender. A fantastic black leaved evergreen shrub from New Zealand which is an exciting hybrid. Small, glossy green leaves stained with black on handsomely patterned branches. Full sun to light shade. Spreading habit is low when young eventually it grows upright to 4′ tall and 5′ wide with a distinctive and beautiful tiered branching pattern. Insignificant small white flowers- they look like little translucent white worms- way more unobtrusive than it sounds. This shrub has shocked us with its hardiness to cold. It survived temperatures in the single digits in a container and didn’t flinch. This is a wonderful foliage shrub that should be more popular. Excellent appearance year round. Drought tolerant. ‘Black Cloud’ Mirror Plant. Use as a small scale ground cover or first rate landscape plant. Very easy to grow.
