ROSE PLANT Filed Sept. 26, 1963 United States Patent 2,436 ROSE PLANT Herbert C. Swim, 1329 College Way, Ontario, Calif., and 0. L. Weeks, 4759 Philadelphia, Chino, Calif. Filed Sept. 26, 1963, Ser. No. 311,929 1 Claim. (Cl. Plt.-29)

The present invention relates to a new and distinct variety of rose plant of the floribunda class, which was originated by us by crossing the variety Spartan (Plant Patent No. 1,357) with the variety Garnette (unpatented).

As the result of this breeding, we have produced a new rose variety which is endowed with the following unique combination of characteristics which are outstanding therein and which distinguish it from its parents, as well as from all other varieties of which we are aware:

(1) A very vigorous habit of plant growth;

(2) Large dark green foliage of heavy, leathery texture;

(3) Relatively straight flower stems of good length, with consequent suitability for the florist trade;

(4) Prolific flo'wer production;

(5) A flower bud form ranging from long-pointed to urn-shaped;

(6) Good flower petalage and double form of the flowers, with the petalage usually ranging from to petals when grown under greenhouse conditions in southern California; and v (7) A distinctive and attractive general color tonality of the flowers from bud to the fully open stage, with the coloration being popularly described as ranging from Dark Red to Dark Purplish Red, with brighter pencil line margins on the petals.

In comparison with its seed parent Spartan, the foliage of our new variety is darker green in color; the prickles have a substantially shorter base and longer length; the buds are long-pointed and urn-shaped, with no flatness at the tip, as distinguished from the shortpointed buds with tendency to flatness at the tip in the case of this parent; the Dark 'Red to Dark Purplish Red flowers of the new variety are distinctly diflerent from the Orange-Red to Reddish Coral flowersof Spartan; and the flowers of the new v'ar iety have little or no fragrance, as distinguished from the very fragrant flowers of Spartan.

As compared with its pollen parent Garnette, the new variety has straighter stems, and the stems are of substantially greater length, as distinguished from the exaggerated zig-zag pattern from node to node in the case of the stem of Garnette; the leaves average substantially larger in size than those of this parent; the flower buds are longer pointed and more urn-shaped than the short-pointed flowers of Garnette; and .the margins of the flower petals have a line of distinctly lighter and brighter red color than the adjacent areas, as distinguished from the lack of any visible contrast between the color of the margin of the petals and the adjacent areas in the flowers of Garnette.

Asexual reproduction of our new variety by budding, as performed at Chino, California, 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 our 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 our new variety, with color terminology in accordance with the Nickerson Color Fan, published by Munsell Color Com- Plant Pat. 2,436 Patented Aug. 11, 1964 pany, Incorporated, of Baltimore, Maryland, except where general color terms of ordinary dictionary significance are obvious:

This description of a newly opened flower was made from a rose grown in a greenhouse during the month of June at Los Angeles, California:
