American Rhododendron Society Plant Registry

        The following rhododendron and azalea names, submitted through the North American registrar, were approved and added to the International Rhododendron Register prior to November 1, 1994 by the Royal Horticultural Society, International Registration Authority for the genus Rhododendron.
        Color numbers refer to the RHS Colour Chart unless noted otherwise. Accompanying color names are taken from A Contribution toward Standardization of Color Names in Horticulture, R D Huse and K L Kelly, edited by D H Voss (ARS, 1984). Species names are those used by the RHS, based upon the recent Edinburgh revision of the genus. Equivalent former and present names are listed in An Alphabetical Checklist of Rhododendron Species (RHS, 1981), and in The Rhododendron Handbook (RHS, 1980).
        Parents of a plant are reported in the conventional order: (seed parent x pollen parent). Abbreviations are used where appropriate: H = hybridized by, G = grown to first flower by, R = raised by, S = selected by, N = named by, I = introduced by, REG = registered by; dates are enclosed in parentheses immediately following the activity.
        Synonyms are names used for a particular clone prior to registration, but unacceptable because of conflict with recommendations of the International Code of Nomenclature for Cultivated Plants - 1980, or because the name was previously registered for a different clone.
