Eugene S. Boerner, deceased, late of Benton, N.Y.,
A new and distinct variety of rose plant of the hybrid tea class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of a large plant size, exceptionally large and leathery leaves which are very resistant to mildew and blackspot, continuous flower production throughout the year when grown in the greenhouse, a classical, spiral opening flower form, with the flowers being borne on long and unusually thick stems, a distinctive and attractive white flower color, with the flowers being larger than those of any other white-flowered variety grown in the same environment, and very long keeping qualities of the flowers..... originated by the late Eugene S. Boerner, deceased, by crossing an unnamed and unpatented pink-flowered seedling derived from crossing the rose variety known as Revelry (Plant Pat. No. 1,850) X the rose variety known as Pink Masterpiece (Plant Pat. No. 2,294) with an unnamed and unpatented pink-flowered seedling of unidentified parentage but designated at #60-2351 in applicants breeding records.
