It is to the industrious researches of J. Frasier, nurseryman, of the King's Road, Chelsea, we are indebted for this charming species of Rhododendron, who introduced it in the year 1792 from the back settlements of Carolina, North America, where it is native.
ARS-GRIN shows it as a synonym of Rhododendron minus Michx. but
PlantList shows it and R. minus as unresolved.
