ROSE PLANT Filed July 22, 1971 The present invention relates to a new and distinct variety of rose plant of the hybrid tea class, which was originated by us by crossing the rose variety known as Peace (Plant Patent No. 591) with an unnamed and unpatented seedling derived from crossing the rose variety known as El Capitan (Plant Patent No. 1,796) with an unnamed and unpatented seedling of Happiness (Plant Patent No. 911) X Chrysler Imperial (Plant Patent No. 1,167). In the final cross, the variety Peace was the seed parent and the unnamed seedling was the pollen parent.

As the result of this breeding, we have produced a new and improved rose variety which is distinguished from its antecedents, as well as from all other rose varieties of which we are aware, as evidenced by the following unique combination of characteristics which are outstanding in the new variety:

(1) Excellence of its hybrid tea habit;

(2) Particularly good foliage having above average disease resistance;

(3) A habit of bearing most of the flowers singly and on long and strong stems;

(4) An ability to retain a high centered flower bud conformation through substantially the entire flower life;

(S) A distinctive, attractive and outstanding pink flower color which is maintained throughout the blooming stages from bud to open flower;

(6) An unusually strong, pleasant and true rose flower fragrance; and

(7) Good lasting flower qualities and remontance of bloom which give the overall effect of almost continuous blooms on an attractive plant which is well covered with excellent foliage.

In comparison with its pollen parent, our new variety has better foliage substance and the foliage is larger in size and lighter green in color; it has a normal complement of thorns as distinguished from the very few thorns of this parent; the flowers have more petals and are borne almost always singly, with only occasional clusters, contrary to this parent; and the flower color is pink instead of bright red like the flower color of this parent.

As compared with it seed parent Peace, the foliage of our new variety is not quite as leathery, and is larger in size and brighter green in color; the flower buds are longer, more pointed and better shaped, but the open flowers are not as large or as fully petaled as the open flowers of this parent which have from 10 to 20 more petals per flower; the pink color of the flower buds and open flowers is completely different from the flower color of Peace which is basically yellow; and the flowers have a very strong rose fragrance while the flowers of Peace have no fragrance.

Asexual reproduction of our new rose variety by budding, as performed at Chino, Calif, shows that the aforementioned characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

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

The following is a detailed description of our new United States Patent 0 Plant Pat. 3,282 Patented Jan. 2, 1973 variety, with color terminology in accordance with the Nickerson Color Fan, published by Munsell Color Company Incorporated, of Baltimore, Md., except where general color terms of ordinary dictionary significance are obvious:
