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, 2003 by the Royal Horticultural Society, International Cultivar 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). The format for reporting parentage conforms with that now used by the ICRA. If the direction of the cross is known, the seed parent is followed by an "(s)". For the plant being described, seed and pollen parents are separated by an upper case "X". If either parent is itself a cross, the individual components within that cross are separated by a lower case "x". Parentheses are used only in describing the more complex crosses.
        Abbreviations are used where appropriate: (a) = azalea, (r) = rhododendron, (v) = vireya rhododendron, (z) = azaleodendron; H = hybridized by, G = grown to first flower by, R = raised by, S = selected by, N = named by, I = introduced commercially 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").
