Abstract
A new variety of rose plant of the floribunda type particularly intended for greenhouse culture and the production of cut flowers, this plant being distinguished by the pleasing and unusual color contrast in its blooms which show a heavy suffusion of red extending in progressing stages from the periphery of the petals toward the base of the petals as the blossom opens passing through a cream colored central portion to a light yellow area at the base of the petals. The new plant is further distinguished by its uniform production of fine quality, medium sized blooms throughout the entire year, under greenhouse conditions, and by lasting quality of the blooms which are carried by sturdy stems and peduncles.
