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 February 1, 1996 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 recent Edinburgh revisions of the genus.
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.
