Abstract
A new variety of Asiatic hybrid lily plant bearing large clusters of medium size flowers of excellent form, strong color, and long persistence, both on the plant and as cut flowers. The flowers of the new plant are particularly characterized by their rose-orchid color tone which is completely new in the upright and outfacing Asiatic divisions of lilies. The plant is highly resistant to disease and shows high tolerance to virus. It is an excellent garden plant. The bulbs may be precooled and forced for cut flowers. The clone is very vigorous and is a good grower and propagator.

A new and distinctive variety of Asiatic hybrid lily plant substantially as herein shown and described, characterized by its high resistance to disease; its high tolerance to virus; the vigorous growth and propagation characteristics of its clone; the excellence of its flower form; its versatility both as a garden plant and a plant produced from precooled bulbs forced for cut flower; and in particular by its rose-orchid color tone, which is unique in the hybrid Asiatic division of lilies suited to forcing and mass commercial cultivation.
