This plant is native to the southeastern United States.

It grows in swamp forests and along stream banks and blooms April through June.

This makes a handsome, high quality large shrub. It is slow growing to usually grow about 8 to 12 feet high x 8 to 12 feet wide, and a little larger in nature. It is native to rich, wet, acidic soils of floodplain forests and swamp edges in dappled sun to full shade in a range from Virginia to central Florida to east Texas to Missouri to southern Illinois & Indiana, plus one site in northeast Illinois in Kankakee County. In landscapes it can grow in full sun, though part shade is best, in a location protected from strong winds with acid, good quality soil. Possibility Place , a wholesale native plant nursery in Monee, Illinois near Joliet, sells some as small plants. They got their stock from Morton Arboretum that collected seed from Kankakee County not that far to their southeast. Otherwise, I have not yet seen this lovely species that is, overall, a rare to very uncommon shrub.
