Arrowleaf butterweed is a robust native perennial that produces bright yellow daisy-like flowers in summer along streambanks and moist mountain meadows. It performs best in consistently moist, rich soils with partial shade and is well suited for naturalized or woodland garden settings. Avoid dry conditions and provide adequate space as it can spread to form attractive clumps.
