Chino, Calif.

Filed Dec. 1, 1964, Ser. No. 415,214 1 Claim. (Cl. Plt.-25)

The present invention relates to a new and distinct variety of rose plant of the fioribunda class, which was originated by us by crossing the variety Spartan (Plant Patent No. 1,357) with the variety Garnette (unpatented).

As the result of this breeding, We have produced a new rose variety having the following unique combination of characteristics which are outstanding therein and which distinguish it from its parents, as well as from all other varieties of which we are aware:

1) A low growing, compact plant habit, with only slight natural spreading, and with an unusual uniformity of growth pattern giving the plants a neat effect;

(2) A relatively continuous blooming habit, giving the effect of substantial color on the plants throughout the major portion of the growing season;

(3) A graceful urn-shaped form of the buds, said buds slowly opening to high-centered blooms of good substance and exposing the center only when the flower is full blown;

(4) A distinctive and attractive pink color of the flowers; and

(5) A remarkable and complete self-cleaning habit of the flowers, usually without aid, as achieved by the timing of the abscission occuring at the base of the peduncle just as the flowers lose their ornamental usefulness, and resulting in the complete dropping of the old flowers promptly.

In comparison with its seed parent, Spartan, our new variety has relatively shorter growth, with the over all growth habit of the plant being lower and more compact than the usual relatively long and over all tall growth of this parent; the new variety is unusually and more regular in its habit of growth, often giving the effect of containment by frequent pruning; the flowers of the new variety are substantially smaller in size than those of this parent; and the flower buds are of urnshaped form in contrast to the pointed ovoid form of the flower buds of Spartan.

As compared with its pollen parent, Garnette, the plants of the new variety are substantially lower and more regular; the flower buds are of urn-shaped form in contrast to the short pointed, ovoid to globular flower buds of this parent; the flowers of the new variety are appreciably. larger in size, and the flowers are pink in color, instead of the red color of the flowers of Garnette.

A sexual reproduction of our new variety by budding, as performed at Chino, California, shows that the aforementioned 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 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 our new variety, with color terminology in accordance with the Nickerson Color Fan, published by Munsell Color Company, Incorporated, of Baltimore, Maryland, except where general color terms of ordinary dictionary significance are obvious:
