Torrey's sulfur buckwheat is a low-maintenance California native perennial that thrives in well-drained, rocky or sandy soils with full sun to part shade. Water sparingly once established, as overwatering is the most common cause of decline. It makes an excellent drought-adapted ground cover or rock garden plant in western landscapes.
