California thermopsis is a rare native lupine relative that produces showy yellow flower spikes in spring and early summer. It prefers well-drained, slightly acidic soils and partial shade in warmer inland locations. Once established, it is relatively self-sufficient and rewards patient gardeners with striking blooms.
