Rhododendron 'Percy Wiseman'

Photo gallery1 photo

Rhododendron 'Percy Wiseman' is a compact evergreen shrub with dark leaves and cream flowers flushed pink in mid-spring. The blooms fade paler as they age, with flowering recorded in May. At ten years, it may reach about 1–1.5 m tall; its mature height and spread are generally 1.5–2.5 m, so allow more room than its early size suggests. It can suit a small garden or container where there is space for that eventual growth. In Southwest Washington, give it dappled shade or sheltered partial sun, acidic soil that drains well, and reliable moisture through dry summer weather to support its evergreen foliage.

The right plant, the right place

Make room for something good.

Its compact early growth and spring flowers suit a small garden or container. Plan for a mature shrub that may spread 1.5–2.5 m.

Where to plant

Choose dappled shade or a sheltered position with partial sun. Allow room around the shrub for its mature spread.

Through the seasons

Cream flowers flushed pink appear in mid-spring and fade paler with age. Dark evergreen foliage remains after flowering.

Southwest Washington gardens

Give it a good start.

The Pacific Northwest generally supports rhododendron growing. In Southwest Washington, provide shelter from hot sun and dependable moisture through dry summer periods.

Soil, drainage & water

Provide acidic, moist, well-drained soil. Avoid sites where water remains around the roots.

A little care goes a long way

Growing well, season after season.

Check soil moisture during dry summer weather, particularly in containers. Water as needed to keep the soil moist while allowing excess water to drain.
