ROSE PLANT Filed June 9, 1967 United States Patent 2,345 ROSE PLANT David L. Armstrong, Ontario, Calif., assignor to Armstrong Nurseries, Inc., Ontario, Calif., a corporation of California Filed June 9, 1967, Ser. No. 645,067 1 Claim. (Cl. Pit.29)

The present invention relates to a new and distinct 'variety of rose plant of the floribunda class, which was originated by me by crossing the rose variety known as Circus (Plant Patent No. 1,382) with the variety known as Ruby Lips (Plant Patent No. 1,775), the former being the seed parent, and the latter being the pollen parent.

The new variety resulted from an extensive breeding program having for its objective to produce improved floribunda rose varieties in which there are combined the best qualities of each of the parent varieties, but which bear flowers of various colors. This objective was fully achieved in the new variety, 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:

(I) A vigorous plant having an attractive, bushy, semi-upright, well-foliaged plant habit;

(2) A very floriferous habit, with the flowers literally covering the plant at peak times and borne in medium sized clusters well spaced over the plant;

(3) Small, moderately double flowers having an attractive open form exposing the center; and

(4) A distinctive, attractive and brilliant dark red flower color which is relatively unfading under most weather conditions and presenting a very attractive mass bloom display on the plant.

In comparison with its seed parent, Circus, the new variety has larger flower clusters, but slightly smaller flowers; the flowers have fewer petals; and the flower color is red as distinguished from the multi-colored flowers of this parent.

As compared with its pollen parent, Ruby Lips, the new variety has a more upright plant habit than the semispreading habit of this parent; the plant is more bushy and more densely foliaged; and the flowers are slightly smaller than the average flower size of this parent.

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 pnopagations.

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:

Type: Bush; outdoor; seedling; for out flowers and for garden decoration. Class: Floribunda. Breeding: Seedling.
