Abstract: A new and distinct variety of greenhouse rose plant which originated as a sport of the variety `Sonia` (U.S. Plant Pat. No. 3,095) and is particularly distinguished by the very light pink coloration of the outer petals of the mature flower which gives it a generally Neyron Rose appearance except for the lower inside portion of the petals at the center of the fully opened bloom which contrasts considerably with respect to the Porcelain Rose and Begonia Rose coloration of the parent plant. This new rose plant variety blooms continuously and profusely the year around under greenhouse conditions with large flowers carried on sturdy, upright stems and with a flower peduncle having a length of about twelve centimeters, the blooms being long lasting on the plant and having a moderate lasting quality as a cut flower. The plant itself has a vigorous and upright growth habit with a free branching character and abundant foliage.
