ROSE PLANT Filed May 26, 1954 United States Patent osa PLANT Francis Meilland, Cap Azura, Cap dAntibes, France, assignor to The Collard-Pyle Company, West Grove, Pa, a corporation of Pennsylvania Application May 26, 1954, Serial No. 432,626

Claims priority, application France July 7, 1953 lClaim. (CI. 47-61) The present invention relates to a new and distinct variety of rose plant of the hybrid tea class, which was originated by me by crossing the variety Peace (Plant Patent No. 591) with the variety Europa (unpaiented).

The primary objective in making this cross was to produce a new variety which combines certain desirable characteristics of both parent varieties and which, in combination, represent a marked difference from both parents, as well as from all other varieties of the hybrid tea class. This objective was fully achieved, as evidenced by the combination in my new variety of a strong and vigorous habit of plant growth, with heavy canes, and the very large and well-formed blooms which are particularly characterized by an unusual permanence of their pink general color tonality from the bud to the fully open bloom stage, remaining substantially unchanged throughout the blooming season. This latter feature is quite unusual in pink roses, and being combined with the large size of the blooms, which average from inches to 5 /2 inches in diameter, and which are fully double, makes my new variety especially attractive and different from any prior pink roses of which I am aware. Besides the desirable vigorous habit of growth of the plants of my new variety, the plants are upright, well-branched and stocky, and their freedom of bloom further contributes to the superior qualities of my new variety which are not duplicated in any other pink variet Xsexual reproduction of my new variety by budding in France, as well as at West Grove, Pennsylvania, U. S. A., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the foliage, stems and blooms of my new variety in different stages of development and as depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of the new variety, with color terminology in accordance with Ridgways Color Standards and Nomenclature, except where gineral color terms of ordinary dictionary significance are 0 v1ous:

Type:Hardy; bush; outdoor; seedling; for cut flowers and for garden decoration. Class: Hybrid tea. Breeding: Seedling.
