ROSE PLANT Filed Jan. 17, 1968 United States Patent O 2,928 ROSE PLANT David L. Armstrong, Ontario, Califi, assignor to Armstrong Nurseries, Inc., Ontario, Califi, a corporation of California Filed Jan. 17, 1968, Ser. No. 698,672

. Int. Cl. A01h /02 US. Cl. Plt.-19 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 Queen Elizabeth (Plant Patent No. 1,259) with the rose variety known as Chrysler Imperial (Plant Patent No. 1,167), 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 the production of new and improved rose varieties in the grandiflora and hybrid tea classes which bear flowers in the pink and red color range, and particularly combining therewith the vigor and attractive plant habit of the parent variety Queen Elizabeth and the better flower qualities and greater flower petalage of the parent variety Chrysler Imperial." 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 rose varieties of which I am aware:

(I) A Very vigorous and upright-spreading plant habit;

(2) Attractive, medium to large, semiglossy foliage which covers the plant well;

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

(4) Double flowers of medium size, with a good urnshaped bud form and a high-centered open flower form; and

(5) A distinctive and attractive dark pink or light red flower color ranging between Carmine and Rose Madder, and usually being somewhat darker in color on the reverse side of the petals.

In comparision with its seed parent Queen Elizabeth, the new variety bears the flowers more singly; the flowers are larger and more double; and the flower color is a considerably darker pink color.

As compared with its pollen parent Chrysler Imperial, the new variety has a more vigorous plant habit, and the flowers range from pink to light red color instead of being of red color like the flowers 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:
