American Rhododendron Society Plant Registry

        Names and descriptions of new American varieties (clones) will be published after the requirements for registration are met. You are urged to submit proposed names to the A.R.S. Plant Registrar before they are actually used. There are thousands of names already in use and a name to be registered must not have been used before and must meet the requirements of the International Code of Nomenclature of Cultivated Plants - 1969.  Requests to register names must be submitted with A.R.S. Plant Registration Cards, completed as fully as possible to the A.R.S. Plant Registrar, Edwin K. Parker, Astoria, OR. A $2.00 FEE IS CHARGED FOR EACH NAME REGISTERED, and should accompany the completed registration. Proposed names and descriptions will be checked by the A.R.S. Plant Registrar and then sent to the International Rhododendron Registrar for final approval and registration. Refer to A.R.S. Quarterly Jan. '74, Vol. 28, No. 1, p. 21 for additional information on registration. Color designations below refer to the Royal Horticultural Society Colour Chart, 1966, unless otherwise stated.
