Hill Company, Richmond, Ind. Filed July 26, 1972, Ser. No. 275,361 Int. Cl. A01h 5/00 U. S. Cl. Plt.-26 1 Claim ABSTRACT OF THE DISCLOSURE BACKGROUND OF THE INVENTION This new variety of rose plant was developed in the course of a breeding program carried on by me at Richmond, Ind., with the primary object of improving the character and quality of greenhourse rose plants for the commercial production of cut flowers, and is the result of a crossing of Seventeen (P.P. 1,765 with Jack Frost (P.P. 2,447) made by me in the spring of 1966. This crossing, among others for the same purpose, was done in the hope of finding improved varieties of pink roses and this resulting seedling, upon flowering in the fall of 1967, was found to have a number of distinctive and advantageous characteristics which, if retained, would have considerable value. A particular characteristic of this new variety, in addition to its vigorous growth habit, abundant production and consistency of propagation, features a profuse lush green foliage making it easier to arrange for all occasions and a flower having a lighter, more iridescent pink color and excellent keeping qualities, very different from the flower of either of its parents, and for that reason it was selected for propagation and test.

Asexual propagation of this new variety of rose plant was done under my direction at Hamilton City, Calif, by budding, and subsequent propagations have proven that the distinctive characteristics of this new variety of rose plant hold true through succeeding propagations from generation to generation.

DESCRIPTION OF THE DRAWING This new variety of rose plant is illustrated by the accompanying drawing which, in full color as closely true as is reasonably possible by conventional color reproduction processes, shows the form of the newly opened flower, very young wood with new leaves, mature wood, buds in several stages of opening, and the upper and under sides of typical mature leaves.

DESCRIPTION OF THE NEW PLANT The following is a detailed description of my new variety of rose plant, with color designations according to Kosters Color Guide (K) and Robert S. Wilsons Horticultural Colour Chart (W), based upon observations made at Richmond, Ind., in 1971.

It is better than its pollen parent in that it has better production and is enirely different in color. This seedling is a prolific grower which supersedes the growth habits of both the seed and pollen parents. It compares with its seed parent Seventeen, Plant Pat. 1765; however, since Seventeen is unable to be propagated with any degree of consistency and the fact that the color of this flower is a more iridescent shade of pink makes it a more profitable commercial rose to grow.

A most distinctive feature of this rose plant is the manner of development of the flower. It commences from a high centered bud with each petal having a pronounced reflux which is a dominant factor in the fully open flower. It has profuse lush green foliage making it easier to arrange from all occasions and it has excellent keeping qualities.

I claim:

1. A new and distinct variety of rose plant substantially as herein shown and described, characterized by its vigorous growth, consistency of propagation, its abundant production of flowers having an iridescent shade of pink color and which develop from a high centered bud with each petal having a pronounced refiux, and by its profuse lush green foliage.
