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 August 1, 1999 by the Royal Horticultural Society, International Registration Authority for the genus Rhododendron. Names conform to the rules and recommendations of the International Code of Nomenclature for Cultivated Plants - 1995.
        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).
        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.
        Metric conversions of flower and leaf measurements are reported in 5mm (0.2") increments for dimensions greater than 25mm (1").
