Description and Cultural Plant Tips

The Island Bush Poppy is a dense evergreen shrub with deep yellow, large poppy-like flowers that bloom profusely in the spring. In coastal areas of Marin, it will bloom almost year round if trimmed occasionally. It looks great with ceanothus and manzanitia in a dry shrub border.

Plant slightly above grade in very well-drained soil in a sunny location. Will take some afternoon shade but prefers sun. Be very careful not to disturb the fragile root ball. Mulch top of soil in a 2 - 3 foot circle around the plant. The best time to plant this native is in the fall to early winter when it can take advantage of the winter rains. It needs no amendments or fertilizers. Cut back by at least half in the fall for a denser, more attractive plant.

Flowers attract nectar loving insects and birds. It also provides cover and habitat for birds.

No significant diseases or pests.
