Regional Picks: Shrubs for Shade – Northwest

Fine Gardening - Issue 188
Cascade Oregon Grape

Shade in the garden might seem like a limitation, but the seasoned gardener knows this is just an opportunity to utilize plants that would wilt in a sunny spot.

As Andrew Bunting says in his article on shrubs for shade, there are plenty of options for bringing interest to your shade garden: “If you take a dim view of the shady spots in your garden, it may be because you haven’t found the right plants to make those areas shine. A few well-chosen shrubs can transform a shadowy area into a showcase, and there are more choices available than you might imagine.”

Find four picks for the Northwest below, and find even more shrubs for shade in Andrew’s article, 9 Great Shrubs for Shade.

 


1. ‘Picturata’ Aucuba

Name: Aucuba japonica ‘Picturata’

Zones: 7–10

Size: 5 to 6 feet tall and 4 to 5 feet wide in 10 years

Conditions: Partial to full shade; prefers well-drained soil but tolerates clay soil

Native range: China, Korea, Japan

A workhorse in a shade garden, aucuba adds bold texture and year-round interest while enduring less-than-ideal conditions. ‘Picturata’, with a bold splash of bright yellow in the center of each leaf, becomes an eye-catching beacon in any garden. This female clone will produce red berries if planted with a male selection, such as ‘Mr. Goldstrike’. Remove reversions of green or spotted foliage to preserve the true form.

 

2. Cascade Oregon Grape

Name: Mahonia nervosa

Zones: 6–9

Size: 2 feet tall and 4 to 6 feet wide

Conditions: Full sun to full shade; prefers well-drained soil but tolerates clay

Native range: Western North America

One of the West Coast’s most useful natives, Cascade Oregon grape forms whorls of deep green, evergreen pinnate leaves. In early spring, short spikes of fragrant golden yellow flowers nestle in the centers of the whorls, followed by edible but very tart blue-purple berries. Established plants form a lovely ground cover with an architectural feel.

 

3. Variegated False Holly

Name: Osmanthus heterophyllus ‘Variegatus’

Zones: 7–9

Size: 7 to 8 feet tall and 5 to 6 feet wide in 10 years; can eventually reach 12 to 15 feet

Conditions: Partial shade; well-drained soil with occasional watering during prolonged dry weather

Native range: Japan, Taiwan

Although this evergreen shrub looks like a holly, it is unrelated. The spiny foliage is dark green with creamy white splashed along the margins. Variegated false holly responds well to pruning and can be maintained as a hedge or allowed to grow into a picturesque large shrub to small tree. In autumn, tiny white flowers open, and a light, fresh fl oral fragrance wafts through the air at an unexpected time of the year. It is drought tolerant once established.

 

4. ‘Purple Stem’ Sweet Box

Name: Sarcococca hookeriana var. digyna ‘Purple Stem’

Zones: 6–9

Size: 3 feet tall and 4 to 5 feet wide

Conditions: Partial to full shade; well-drained soil with supplemental water during prolonged dry weather

Native range: China

The intense vanilla fragrance of sweet box makes it a staple for the winter garden. This graceful selection from a variable species sets itself apart from others with thin, willowy stems that are blushed deep purple. The delicate arching branches form a slow-spreading clump that can be a perfect skirt around trees and shrubs. The glossy evergreen foliage sparkles in dark shady areas, making this a must-have plant for woodland plantings.
