According to Armitage, this native of Alpine meadows is hardy in Z3-6. It needs cool mild summers, and does well in the Pacific Northwest and at the Denver Botanic Garden.

Prefers alkaline soil and consistent moisture.

The juice from the roots is used in herbal medicine. Wild plants are easily confused with deadly Veratrum species.
