[Wikipedia] Cultivation: Astragalus purshii is cultivated as an ornamental plant. It is an excellent rock garden plant, as a serial ephemeral species, and an addition to municipal and agency sustainable landscape and restoration projects. It is also a component for reclamation projects.
Seeds do not require stratification and are tolerant of low precipitation and drought (municipal landscaping candidate to reduce water usage). Plants are hardy to -33F.[3][4] (link added by Mary Ann Machi)
