Synonym(s): Cleome serrulata var. angusta
USDA Symbol: clse
USDA Native Status: L48 (N), CAN (N)
Annual with erect stem is leafy and branching above. Leaflets occur in threes. Branched stems have palmately compound leaves and, in racemes at ends of branches, pink or reddish-purple flowers (sometimes white). Showy clusters of pink flowers continue to elongate during the season, so that the slender seed capsules may be present even while the upper portion of the inflorescence in still flowering. Six conspicuous stamens protrude beyond the pink petals. Rocky Mountain beeplant may attain 4-5 ft.
Flowers produce copious nectar and attract bees, hence the common name. Indians boiled the strong leaves for food and as a stomachache remedy. In times of drought early Spanish-Americans made tortillas from the barely palatable but nourishing seeds.
