July 1, 1969 L. ARMSTRONG Plant Pat. 2,900

ROSE PLANT Filed Dec. 13, 1967 United States Patent 2,900 ROSE PLANT David L. Armstrong, Ontario, Calif., assignor to Armstrong Nurseries, Inc., Ontario, Caliii, a corporation of California Filed Dec. 13, 1967, Ser. No. 690,364 Int. Cl. A01h /02 U.S. Cl. Plt.15 1 Claim 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 rose variety known as Helen Traubel (Plant Patent No. 1,028) with the rose variety known as Tiffany (Plant Patent -No. 1,304), the former being the seed parent and the latter being the pollen parent.

The new variety resulted from an extensive breeding program conducted by me and having for its objective to produce improved hybrid rose varieties bearing flowers in the pink and pink-and-yellow-blend color range, and combining the large flower size and superior bud and open flower form that is characteristic of the parent varieties. This variety is one of the achievements of the objective, 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

(1) A vigorous, bushy, attractive plant of rounded and upright to spreading habit;

(2) A habit of usually bearing its flowers singly on medium to long stems of good strength;

(3) Attractive, quite double, medium to large flowers of excellent urn-shaped bud form and graceful openflower form, combining the best of these aspects of the parent varieties; and

(4) A distinctive, attractive and clear light yellow flower color.

In comparison with its seed parent Helen Traubel, the new variety has a more bushy and compact plant habit; greater flower petalage; and a light yellow flower color instead of the apricot-pink flower color of this parent.

As compared with its pollen parent Tiffany, the new variety primarily differs by having a light yellow flower color instead of the pink or pink-and-yellow blended flower color 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 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:
