May 13, 1975 ROSE PLANT Filed March 21, 1974 United States Patent Plant Pat. 3,719 Patented May 13, 1975 3,719 ROSE PLANT O. L. Weeks, 926 W. Philadelphia,

Ontario, Calif. 91762 Filed Mar. 21, 1974, Ser. No. 453,385 Int. Cl. A01h 5/00 I US. Cl. Plt.-14 ,1 Claim 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 two unnamed and unpatented rose seedlings, respectively identified in my breeding records as #604-A-16 and #6122-C-97, the former being the seed parent. and the latter the pollen parent.

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

(4) A gardenia-like quality and unusually good substance of the flower petals which is uncommon in most whiteflowered varieties; and

(5) A creamy-white flower color less than pure stark white, but still definitely giving the flowers an overall white-effect when the plants are in heavy bloom;

In comparison with its pollen parent, the plant of. my new variety is much more vigorous and free-blooming; its flowers are much larger, more fully petalled and more elegantly shaped than those of this parent; and the flower color is a creamy white in contrast to the pale yellow flower color of the parent variety.

As compared with its seed parent, the plant of my new variety has considerably greater vigor and overall-growth habit; it is a notably more profuse bloomer; and the flowers of the new variety are much larger and have much better petal substance, while being of a similar color.

Asexual reproduction of my new rose variety by budding, as perofrmed by me at Ontario, Calif, shows that the aforementioned 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 Munsells Color Cascade, published by Munsell Color Company, Inc., of Baltimore, Md., except where general color terms of ordinary dictionary significance are obvious:

I claim:

1. A new and distinct variety of rose plant of the hybrid tea class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of an extremely vigorous habit of growth, with production of exceptionally long and strong stems which are capable of supporting the heavy blooms well, an extraordinarily profuse blooming habit and excellent and amazingly rapid repetition of the blooming cycle when the plant is pruned back, the production of unusually long buds which open to large beautifully formed open flowers of a classic exhibition type and having many petals, a gardenia-like quality and unusually good substance of the flower petals which is uncommon in most white-flowered varieties, and a creamy-white flower color less than pure stark white, but, still definitely giving the flowers an overall white effect when the plants are in heavy bloom.
