The bushy sulfur buckwheat (var. dumosum) is a mounding, shrubby perennial native to California and Oregon, valued for its airy clusters of yellow flowers and silvery foliage. Plant in fast-draining, lean soil in full sun to part shade and water sparingly once roots are established. Its compact, bushy habit makes it especially attractive as a low-maintenance edging or slope stabilization plant.
