ROSE PLANT Filed June 7, 1967 United States Patent 2,844 ROSE PLANT David L. Armstrong, Ontario, Calif., assignor to Armstrong Nurseries, Inc., Ontario, Calif., a corporation of California Filed June 7, 1967, Ser. No. 644,399 1 Claim. (Cl. Plt.2tl)

The present invention relates to a new and distinct variety of rose plant of the grandiflora class, which was originated by me by crossing the rose variety known as Roundelay (Plant Patent No. 1,280) with the variety known as El Capitan (Plant Patent No. 1,796), the former being the seed parent and the latter being the pollen parent.

This new variety was the result of an extended breeding program having for its objective to produce improved red-flowered rose varieties in the grandiflora class. The objective was fully achieved, as evidenced by the following unique combination of characteristics which are outstanding in this new variety and which distinguish it from ts parents, as well as from all other rose vareties of which I am aware:

(l) A vigorous plant of semi-upright habit and having canes and branches heavier or of greater caliper in proportion to the plant and foliage than most garden rose varieties;

(2) Attractive, dark green, medium to large, leathery and semi-glossy foliage;

(3) A very floriferous habit, with the flowers borne on medium to long stems in small clusters, as well as singly, as exemplary of the grandiflora class;

(4) An attractive flower bud form, said buds being moderately short but quite symmetrical and high-centered and usually urn-shaped, and having excellent heavy substance, with consequent much longer lasting qualities than that of most garden roses, both on the plant and as cut flowers;

(5) Quite double flowers of medium size intermediate those of the parent varieties; and

(6) A distinctive, attractive and relatively dark but bright red flower color that is resistant to fading or bluing under most weather conditions.

The new variety differs from its seed parent, Roundelay, by having larger flowers and generally longer stems, said stems being relatively heavier or of greater caliper, and the flowers have little or no fragrance contrary to the quite definite flower fragrance of this parent.

As compared with its pollen parent, El Capitan, the new variety bears flowers having from 10 to more petals, on the average, with the petals often being smaller toward the center of the flower than in the typical flowers of this parent, and the stems of the new variety are relatively greater in caliper than the average stems of El Capitan.

Asexual reproduction of my new variety by budding, as performed at Ontario, Calif, 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 the new variety, with color terminology in accordance with Robert F. Wilsons Horticultural Colour Chart (hereinafter abbreviated (W)) and Robert Ridgways Color Standards and Nomenclature (hereinafter abbreviated (R) as indicated:
