sulphur flower buckwheat
Intense yellow flowers in flat-topped clusters sit atop short stems above grey to green foliage. Ranging in height from 10 to 18 inches, this highly variable and widely distributed California native is an excellent addition to the drought tolerant garden. Provide decent drainage and occasional to no irrigation once established. Full sun to light shade. Just like all buckwheats, this species is loved by bees and butterflies. The foliage is deer resistant but they may nibble the flowers.
