United States Patent 1 Plant Pat. 3,910

3,910 ROSE Roy L. Byrum, Richmond, Ind., assignor to Joseph H. Hill Company, Richmond, Ind. Filed Mar. 31, 1975, Ser. No. 563,293 Int. Cl. A0111 5/00 US. Cl. Plt.26 1 Claim Ansrnacr on THE nrscrosuan BACKGROUND OF THE NEW PLANT This new rose plant is a result of my crossing of Junior Bridesmaid (Plant Pat. No. 2,446), as seed parent, with Jack Frost (Plant Pat. No. 2,447) with the object of developing a new pink floribunda variety that would incorporate all of the good qualities of both of its parents. This crossing was made at Richmond, Ind, in the spring of 1969 and the first flowering of this seedling in October of 1970 appeared to indicate that my objectives would be realized. Accordingly asexual propagation of this seedling was done under my direction by budding at Richmond, Ind, and several successive generations of this plant have demonstrated that its novel characteristics hold true from generation to generation and appear to be firmly fixed. Propagation of this new variety of rose plant by budding at Hamilton City, Calif, has also shown the distinctive characteristics of the plant to told true.

DESCRIPTION OF THE DRAWING This new variety of hybrid rose plant is illustrated by the accompanying photographic drawing which shows, in full color, the form of the fully opened flowers and four stages of the buds, top and under side views of typical leaves, specimens of young and old wood, and side and face views of the reproductive organs as seen when the flower petals have been removed, the colors shown being as nearly true as can be reasonably expected from conventional photographic procedures.

DESCRIPTION OF THE NEW PLANT The following is a description, in detail, of my new rose plant variety with color designations according to Kosters Color Guide (K) and the Horticultural Colour Chart (W) produced by Robert F.

Aside from being of a distinctively ditferent flower color than either of its parents, this new variety propagates better than its seed parent Junior Bridesmaid (Plant Pat. No. 2,446), produces a more vigorous plant in greenhouse and has slightly larger buds and flowers than the seed parent. The new plant does however, have all of the excellent qualities of its pollen parent Jack Frost (Plant Pat. No. 2,447).

The new plant is a vigorous and upright growing plant with abundant foliage and continuous production of towers borne on strong stems of medium length and the keeping quality of the blooms as cut flowers is excellent.

I claim:

1. A new and distinct variety of rose plant substantially as herein shown and described, characterized by the distinctive pink coloration of its flowers, its much branched, free, vigorous and upright growth habit, and by its continuous and abundant production of flowers borne on strong straight stems and having excellent keeping qualities as cut flowers.
