Application October 26, 1955, Serial No. 543,044

1 Claim. (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 Senateur Potie (unpatented) with the variety Poinsettia (unpatented).

The primary objective in making this cross was to produce a new variety of rose embodying a combination of desirable qualities and characteristics that are not found together in any variety heretofore known in commerce. This objective was fully achieved, as evidenced by the fact that my new variety is particularly characterized by the following outstanding features:

(1) Its vigorous habit of growth;

(2) The excellent form of its buds and open blooms which is maintained from the bud stage through maturity;

(3) The great abundance of its flower petals;

(4) The firm texture of its flower petals, and their consequent resistance to adverse weather conditions;

(5) The clear pink general color tonality of its blooms which is maintained throughout the life thereof without significant fading or bluing; and

(6) The unusually strong and clear fragrance of its flowers.

The foregoing chracteristics and distinctions definitely differentiate my new variety from its parents, as well as from all other varieties of its class of which I am aware, and asexual reproduction of my new variety by budding, as performed by me in Spain, and as performed at West Grove, Pennsylvania, U. S. A., shows that the unique combination of characteristics noted in the foregoing comes true to form and is established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of my new variety in different stages of development and as depicted in color as nearly true as it is reasonably possibly to make the same in a color illustration of this character.

The following is a detailed description of my new variety, with color terminology in accordance with the Horticultural Color Chart of the Royal Horticultural Society, except where general color terms of ordinary dictionary significance are obvious:
