Formerly Cleome lutea. Drought tolerant native annual with pincushion-like yellow flowers, blooming April to September. Colonizer, preferring open and disturbed sites on arid and semi-arid shrublands and woodlands, sometimes in large colonies; up to 9,000 ft. elevation. Valuable nectar and pollen for numerous native bee species. Use as a soil stabilizer and short-term emergency food source for native pollinators after disturbance, until perennial forbs bloom.
