Rocky Mountain Beeplant (Cleome serrulata) is an annual wildflower native to western North America, where it thrives in prairies, foothills, and disturbed areas with well-drained soils. Known for its striking, pink to purple flowers arranged in showy, spherical clusters, this plant provides a vibrant display from mid-summer to early fall. Its tall, upright growth and abundant nectar production make it a valuable addition to pollinator gardens, prairie restorations, and wildlife habitats.
 
Ecologically, Rocky Mountain Beeplant is a powerhouse for pollinators, drawing in native bees, butterflies, hummingbirds, and other beneficial insects. It is particularly favored by bumblebees and long-tongued bees, which seek out its rich nectar stores. Additionally, this plant plays an essential role in supporting biodiversity, as its seeds are an important food source for birds and small mammals. Indigenous communities have historically used this species for food, dye, and medicine, highlighting its deep ecological and cultural significance.
 
This adaptable wildflower prefers full sun and tolerates a range of soil types, from sandy to clay-rich. It thrives in disturbed sites, making it an excellent choice for habitat restoration and erosion control. Rocky Mountain Beeplant is easily grown from seed, requiring a period of cold stratification to break dormancy. Direct sowing in the fall or providing 2-4 weeks of cold, moist stratification in spring ensures optimal germination.
