Cleomella serrulata

Rocky Mountain Beeplant. Annual. Cleome serrulata and Peritoma serrulatum are synonyms. Rose-pink buds open into light-pink blossoms, creating a two-tone effect, from June to late summer (in Cheyenne). Best in full sun and dry or very well-drained soil. It can be challenging to get your first plants going. (I got mine via wintersowing.) Choose a place where they can self-sow year after year, and they'll reward you and your pollinators with a breath-taking display. 36"- 48" tall x 12"- 24" wide.
