Classification

''Rhododendron catawbiense'' belongs to the subgenus ''Hymenanthes'', within which it is further assigned to section ''Ponticum'' and subsection ''Pontica''. The latter—one of the 24 subsections of ''Ponticum''—also contains about a dozen other species. The taxonomy has been confused by a tendency to group all large leaved Rhododendrons under the catch-all ''R. catawbiense''.
