ROSE PLANT Filed Feb. 27, 1967 United States Patent 2,832 ROSE PLANT David L. Armstrong and Herbert C. Swim, Ontario, Calif., assignors to Armstrong Nurseries, Inc., Ontario, Calif a corporation of California Filed Feb. 27, 1967, Ser. No. 619,077 1 Claim. (Cl. Plt.-20)

The present invention relates to a new and distinct variety of rose plant of the hybrid tea class, which was originated by us by crossing an unnamed and unpatented seedling of unidentified parentage with the variety known as Chrysler Imperial (Plant Patent No. 1,167), the former being the seed parent, and the latter being the pollen parent. The unnamed seed parent was a very vigorous, upright, relatively thornless, semi-double light red flowered hybrid tea rose variety which bore flowers on exceptionally long stems and whose flowers had a moderately strong fragrance.

The new variety resulted from an extensive breeding program having for its primary objective to produce improved red flowered hybrid tea rose varieties particularly emphasizing flower fragrance, bud and flower form, rich red flower color, and good plant habit with adequate vigor of growth. This objective was fully achieved, along with other desirable features, 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 we are aware:

(I) A moderately vigorous, attractive and upright plant habit;

(2) Medium sized, dark green leathery and semi-glossy mature foliage, contrasting with attractive dark reddish new growth;

(3) Relatively few thorns;

(4) A floriferous habit, with the flowers generally borne singly on medium length to long stems;

(5) Attractive urn-shaped buds which develop into high-centered half-open and open flowers of good form;

(6) Medium to large sized flowers having good petalage;

(7) A distinctive and attractive flower color ranging between Rose Red and Cardinal Red; and

(8) A rich, strong and spicy flower fragrance.

In comparison with its unnamed seed parent, the new variety primarily differs therefrom by its more double and darker red flowers, with better urn-shaped buds and open flower form, together with a stronger fragrance than the flowers of this parent, but having a somewhat less vigorous pl-ant habit, though adequate, with medium to long stems instead of the exceptionally long stems of this parent. I

As compared with its pollen parent Chrysler Imperial, the new variety primarily dilfers therefrom by having' a more upright plant habit, with somewhat longer single stems, together with a slightly more open habit or less dense foliage, and the flowers of the new variety have fewer petals on an average than those of this parent.

Asexual reproduction of our 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 vegative growth and flowers of our new variety in different stages of development 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 Plant. Pat. 2,832 Patented Sept. 10, 1968 F.
