Dieteria bigelovii var. bigelovii

Bigelow's tansyaster is a native Rocky Mountain wildflower valued for its showy purple daisy-like blooms in late summer and fall. It is best suited to garden settings that mimic its natural high-elevation habitat — well-drained, average soils in partial to full sun. This species is relatively undemanding once established and is a wonderful addition to wildlife or native plant gardens in the Mountain West.
