Native of the south-eastern USA, from Georgia and N. Florida to S.E. Mississippi; discovered before 1865 by Dr Chapman; introduced to Britain by Sargent in 1916. In general aspect it resembles R. canescens but differs in flower-colour and is more glandular. It has proved quite hardy at Kew despite its southern provenance.
