Rocky Mountain Beeplant Cleome serrulata

 

A robust annual that grows to 3 feet tall, with large clover like leaves and branches tipped with clusters of bright lavender purple flowers similar to a domestic spider flower. Found in shrub land and meadow communities at low elevations throughout the state. Drought tolerant, but prospers best in moist soil in full sun, with a minimum of competition from perennial plants. Looks good in mass plantings with other annuals. Plant in late fall for early spring emergence. Self-seeds readily.

Flowers July-September.
