PERITOMA serrulata (Rocky Mountain beeplant)

Formerly Cleome serrulata. Tall moderately drought tolerant native annual with pincushionlike bright pink flowers, blooming June to September. Colonizer, preferring open and disturbed sites on roadsides, moist prairies, shrublands, mountain woodlands and in old pastures and rangelands, sometimes in large colonies; up to 10,000 ft. elevation. Valuable nectar and pollen for numerous native bees, honeybees and Monarch butterflies; seeds for upland game birds. Use as a soil stabilizer and emergency short-term food source for native pollinators after disturbance, until perennial forbs bloom.
