ROSE PLANT Filed Sept. 6. 1973 United States Patent "Ice 3,639 ROSE PLANT Roy L. Byrum, Richmond, Ind.,-assignor to Joseph H. Hill Company, Richmond, Ind. Filed Sept. 6, 1973, Ser. No. 394,629 Int. Cl. A01h 5/00 U.S. Cl. Plt.-29 1 Claim ABSTRACT OF THE DISCLOSURE A new variety of floribunda hybrid rose plant for continuous greenhouse forcing distinguished by its abundant production of medium-small, well shaped, cardinal red to rose red blossoms on'medium-strong 16 to 18 inch stems, its free growth habit and abundant foliage, the ability to break freely from a cut to produce. from 55 to 60 blooms annually, and the ability to remain unaffected by dark cloudy weather so as to produce an unusually small amount of blind canes.

Background of the Invention seedling was selected for propagation because it appeared to have the desired flower production and growth characteristics, as well as the good traits of both its parents. Asexual propagation of this new variety by budding has been carried on under my direction at Hamilton City, Calif., and at Richmond, Ind., and from generation to generation, the plants of this new variety have been observed to retain all of the distinctive characteristics of the original seedling wherefor these characteristics are deemed to be fixed and hold true from propagation to propagation.

Description of the Drawing This new variety of rose plant is illustrated by the accompanying full color photographic drawing which shows the form of the opened flower and buds as well as face and reverse sides of typical leaves and young and 01d specimens of the wood, the color rendition being as nearly true as it is reasonably possible to accomplish through conventional commercial photographic procedures.

Wilson (W), published by The Royal Horticultural Society at London, England. All observations were made of plants and cut flowers grown in a greenhouse at Richmond, Ind.

This new variety of rose plant is particularly distinguished by its exceptionally good keeping qualities and vase life. There are very few, if any, disbuds; the plant has excellent vegetative growth from base to top of plant; and it breaks freely from a cut, producing up to blooms, or more, annually. This plant is uneifected by dark cloudy weather and, therefore, produces an unusually small amount of blind canes.

This plant is similar to Mary De Vor, P.P. 2,838, but has a more profuse growth habit and a more rapid comeback from a cut with a better production of blooms. This plant is better than its seed parent in that it has longer stems, better retention of foliage, more abundant foliage, and larger flowers. This plant also improves on its pollen parent by producing longer stems and is commercially of more economic value because it is not a novelty variety.

I claim:

1. A new and distinctive variety of rose plant substantially as herein shown and described, characterized by its rapid vegetative growth and the ability to break freely from a cut to maintain a high production rate of about 60 flowers annually; by its small amount of blind canes due to dark cloudy weather; and by the longer stem length and good keeping qualities of its blooms.
