ROSE PLANT Filed Feb. 27. 196'? United States Patent 2,836 ROSE PLANT David L. Armstrong and Herbert C. Swim, Ontario, Califi,

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 the rose variety known as Helen Traubel (Plant Patent No. 1,028) with an unnamed variety which is the subject of Plant Patent No. 1,254, the former being the seed parent and the latter bein the pollen parent.

This new variety resulted from an extensive breeding program having for its primary objectives to produce improved rose varieties in the yellow to pink flowered color range, including blends of these colors, and combining as far as possible the excellent urn-shaped bud form and large flower size of Helen Traubel with the greater petalage and excellent plant habit of the unnamed pollen patent. Also desired was a strong flower fragrance which previous experience had shown to appear in a large number of seedlings derived from crosses using this pollen parent. These objectives were 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:

(1) A moderately vigorous plant habit, with a semispreading or at least intermediate spreading to upright habit resembling that of Helen Traubel and sometimes more spreading than the latter;

(2) Relatively large, dark green, leathery, semi-glossy and disease resistant foliage;

(3) A quite floriferous habit, with the flowers borne generally singly on long and strong stems;

(4) A very attractive urn-shaped bud form and an excellent high-centered half-open and open flower form resulting in excellent exhibition type flowers;

(5) Large flowers with good petalage;

(6) A distinctive and attractive pale to light yellow flower color; and

(7) A rich and strong flower fragrance which is unusual in yellow roses.

In comparison with its seed parent Helen Traubel, the new variety has a light yellow flower color instead of the Apricot Pink and yellow blend of the flower color of this parent; it has considerably more flower petals than the average petalage of the parent; and the flowers of the new variety have a strong fragrance instead of the relatively mild fragrance of those of Helen Traubel.

As compared with its unnamed pollen parent, the new variety has a more spreading plant habit and generally better and more consistent urn-shaped buds and halfopen flowers, with the buds having more of an urn shape and being longer than the more fat and shorter buds 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 vegetative growth and flowers of our new variety in different stages of development, with some of the flowers and vegetative growth being depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of thischaracter.
