Abstract
A new and distinct variety of Hybrid Tea rose plant is provided which abundantly forms on a substantially continuous basis attractive elegant long-lasting double white blossoms wherein the blossom petals of a mature blossom tend to enclose the central portion of the blossom. The new variety is a spontaneous mutation of unknown causation of the ‘Meivamo’ variety (U.S. Plant Pat. No. 8,619). The plant exhibits a vigorous and upright growth habit, and strong and vigorous dark green foliage with a glossy aspect. No particular susceptibility to crytogamic diseases has been observed. The attractive dark green foliage contrasts nicely with the pure white blossom coloration. The new variety is well suited for cut flower production under greenhouse growing conditions. Excellent forcing has been observed particularly during the winter.
