Abstract
A new and distinct variety of rose plant of the intermediate Class is provided which abundantly forms on a substantially continuous basis attractive red-purple blossoms that are lighter in coloration on the upper surface of the petals than on the under surface. The growth habit is vigorous and erect. Attractive medium green semi-glossy foliage is formed that contrast nicely with the blossoms coloration. Tolerance to diseases is good particularly with respect to Oidium. The new variety forces well under greenhouse growing conditions and is well suited for cut flower production under such conditions.
