United States Patent 2,258 ROSE PLANT Michel Kriloif, Antibes, Alpes-Maritimes, France, assignor to Ilgenfritz Nurseries, Inc., Monroe, Mich., a corporation of Michigan Filed Mar. 20, 1962, Ser. No. 181,218 1 Claim. (Cl. 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 known in the United States as Peace, but known in France and Belgium as Mme. A. Meilland (U.S. Plant Patent No. 591) with the variety known as Baccara (U.S. Plant Plant No. 1,367).

As the result of this breeding, I have produced a new variety of rose plant which is distinguished from its parents, as well as from all other varieties of which I am aware, as evidenced by the following unique com bination of characteristics which are outstanding in the new variety:

(1) A strong and vigorous habit of growth;

(2) Very good resistance to mildew and blackspot;

(3) Abundant production of blooms;

(4) Large and well shaped blooms;

(5) A symmetrical arrangement of the flower petals resembling a rose window; and

(6) A very vivid and very luminous red general color tonality of the flowers.

Asexual reproduction of my new variety by grafting, as performed at Antibes, France, 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 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 possible 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 Rene Oberthurs Repertoire de Couleurs, except where general color terms of ordinary dictionary significance are obvious:

This description of a newly opened flower was made from a rose grown outdoors during the month of June at Antibes, France:

Intermediate petal: outside surface-Rouge Andrinople, Plate 92-1; inside surface-Rouge Andrinople; Plate 92-1. Inner petal: outside surfaceRouge Neyron, Plate 119- 3; inside surfaceRouge Neyron, Plate 119-3.

This description was made from a rose that was open for three days outdoors during the month of June at Antibes, France:
