ROSE PLANT Filed Nov. 17, 1965 United States Patent 2,705 ROSE PLANT David L. Armstrong, Ontario, Calif., assignor to Arrnstrong Nurseries, Inc., Ontario, Calif., a corporation of California Filed Nov. 17, 1965, Ser. No. 508,401 1 Claim. (Cl. Plt.)

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 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.

The general objective of this breeding was to produce a new and improved variety of rose plant which bears red flowers, while combining the double flower petalage and the large, attractive, disease-resistant foliage characteristics of the parent variety Roundelay with the large flower size and good flower form of the parent variety El Capitan, together with the great vigor and floriferousness of both parents. This objective was fully achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents, as well as from all other varieties of which I am aware:

(1) A very vigorous, attractive, and upright-spreading plant habit;

(2) Large, attractive, leathery, semi-glossy and diseaseresistant dark green foliage;

(3) Very good floriferousness, with the flowers borne both singly and in small clusters;

(4) Medium to long flower stems;

(5) Attractive urn-shaped flower buds;

(6) Medium to large, double flowers; and

(7) A distinctive and very attractive, rich and often glowing red flower color ranging between Geranium Lake and Signal Red.

In comparison with its seed parent, Roundelay, the new variety bears flowers of somewhat larger size and the flowers have a more orange-red color instead of the dark red flower color of this parent.

As compared with its pollen parent, El Capitan, the flowers of the new variety are orange-red in color instead of near cherry red like the flower color of this parent.

Asexual reproduction of my new variety by budding, as performed at Ontario, California, hows 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.
