A compact California native shrub with silvery foliage and spikes of blue and white flowers. Extremely drought-tolerant once established and thrives in poor soils.

Why grow it

Silver bush lupine offers a finer-textured alternative to many native California shrubs, with silvery foliage that provides year-round visual interest beyond its flowering period. Among lupines, its compact habit and silvery leaves make it particularly useful for smaller gardens or erosion control on slopes where larger species might overpower the design. Its ability to establish in poor, rocky, or sandy soils without amendment gives it an advantage in restoration plantings where soil improvement is impractical.

Watch out for

This species can be slow to establish from seed and may take two to three years to reach mature size, so patience is needed during the establishment phase. In areas with naturally high soil moisture or humid summers, good drainage becomes critical to prevent root rot, even though mature plants are drought-tolerant.
