Small evergreen shrub, slowly spreading by stolons. Short erect stems carry large pinnate leaves with spiny-toothed glossy dark green leaflets. In late autumn and winter the foliage often turns an attractive deep wine-red. Racemes of yellow flowers in spring, followed in summer by clusters of dark blue berries with a white powdery bloom.
Moist, well drained, humus-rich soil in part shade. Tolerates deep shade and also full sun in cooler regions. Once established will survive periods of drought.
From seed, cuttings or by separating rooted suckers
Excellent ground cover and understorey plant for shady positions.
An extract of the root was used medicinally by Native North Americans.
Native to the northwest coast of North America from British Columbia to central California
