Balsamorhiza sagittata grows east of the Cascade-Sierra axis to the Rocky Mountains and Black Hills. It is one of the more spectacular of all spring-flowering plants in the northwestern United States. Hybrids occur along lines of contact between B. sagittata and almost all species of sect. Balsamorhiza except B. macrophylla (a high polyploid).
