Description
Swamp sunflower is a native perennial member of the aster family and can be found from NY to FL to TX. It is a large perennial that can grow up to 8 feet tall with showy yellow daisy-like flowers from mid to late summer into fall. Prune plants back in June to encourage branching. It prefers moist to occasionally wet acidic sandy to clay loams in full sun. It can be grown on drier soils if adequate moisture is provided. It will tolerate part shade but flowers better in full sun. This plant is a favorite of pollinators and songbirds. There are shorter cultivars available if desired.

Use this plant in the back border of a native/pollinator garden, naturalized area, or along streams and ponds. Give it room to grow and spread and you will have a profusion of late-season flowers when little else is blooming.

This plant was selected as the 2007 NC Wildflower of the Year
