ROSE PLANT Filed July 28, 1967 United States Patent 2,876 ROSE PLANT Walter E. Lammerts, Freedom, Calif, assignor to Amling- De Vor Nurseries, Inc., Livermore, Calif., a corporation of California Filed July 28, 1967, Ser. No. 656,959 Int. Cl. A01h /02 US. Cl. Plt.11 1 Claim The present invention relates to a new and distinct variety of rose plant of the hybrid grandiflora class, which was originated by me by crossing the rose variety known as Queen Elizabeth (Plant Patent No. 1,259) with the variety known as Rumba (Plant Patent No. 1,919).

As the result of this breeding, I have produced a new and improved rose variety which is distinguished from its parents, as well as from all other rose varieties of which I am aware, as evidenced by the following unique combination of characteristics which are outstanding therein:

(1) A Well-defined grandiflora habit, with a bush height approximately the same as that of Queen Elizabeth and forming a moderately tall, well-shaped plant having upright and well-branched canes;

(2) Good adjustability to high-saline soils and good resistance to salt burn;

(3) Medium large, glossy, dark green foliage which is essentially disease resistant;

(4) Abundant bloom production from early spring to late fall, with the flowers usually borne in typical grandiflora clusters, but sometimes singly or in tighter clusters, on strong stems and necks;

(5) Urn-shaped buds which open to high-centered blooms at the half-open stage, said blooms being regular, well-imbricated, medium large in Sil and having good petalage when fully open, and the petals being unusually heavy, long-lasting, and very resistant to rain and Weather injury, with the bloom tending to retain its crispness even through heavy rain downpours;

(6) A distinctive and attractive general color tonality of the flowers progressing from Canary Yellow in the bud and protected petals and Blood where the light first hits, to a gradual overall suffusion of Cardinal Rose, with the yellow pigment being much less intense and even sometimes appearing as ivory and the red color being also much less reduced under lower light intensities, while all colors tend to greatly improve and attain maximum development under conditions of bright sun and warm weather; and

(7) A light spicy flower fragrance.

In comparison with its parent varieties, the new variety has largely inherited its striking flower color change, heavy petal substance and good petalage from the parent variety Rumba, which bears small, bright yellow to red floribunda blooms in tight clusters on a moderately small, rounded bush having small, glossy foliage, while the greater bloom size, longer stems, vigorous and upright plant habit and larger foliage of the new variety are largely inherited from the parent Queen Elizabet which is a vigorous, upright, pink-flowered grandiflora variety.

The new variety most nearly resembles the variety known "as Granada (Plant Patent No. 2,214), which has a moderately spreading habit, with flowers having from 18 to 25 petals and ranging in color from lemonyellow to nasturtium-red, but the new variety is easily distinguished therefrom by a more upright plant habit, a better imbricated bloom, a significantly greater petalage, heavier petals and a more intense color change of the flowers.

Asexual reproduction of my new variety by budding, as performed by me at Livermore, Calif., shows that the Plant Pat. 2,876 Patented Apr. 1, 1969 ICC 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 my new variety, with color terminology in accordance with the Horticultural Colour Chart of the British Colour Council, except where general color terms of ordinary dictionary significance are obvious, as based upon observations of specimens grown at Shafter, Calif.
