United States Patent 2,226 RGSE PLANT Herbert C. Swim, flntario, and 0.1.Weelrs, Chino, Caliii, assigners to Weelrs Wholesale Rose Grower, Chino, Calif.

Filed Mar. 13, 1962, Ser. No. 179,5ll2 1 Claim. (Cl. 47-61) The present invention relates to a new and distinct variety of rose plant of the (floribunda class, which was originated by us by crossing the variety Yellow Pinocchio (Plant Patent No. 992) with the variety Circus (Plant Patent No. 1,382).

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:

(I) A low-growing and compact habit of plant growth;

(2) Large, glossy, dark green leaves;

(3) An abundance of flowers at all times during the blooming period, with relatively large quantities of blooms in the individual sprays, as compared with other varieties of comparable plant size;

(4) An attractive form of both the buds and the open flowers, with the buds and open flowers being of relatively small size in general eflect, as compared with other varieties;

(5) Double flower petalage;

(6) A distinctive and attractive deep lemon yellow general color tonality of the flowers; and

(7) Good persistence of the yellow flower color throughout the life of the flowers.

In comparison with its seed parent "Yellow Pinocchio," the flowers of our new variety are of a distinctively different color which may be characterized as intense lemon yellow, fading to lemon yellow of a somewhat lesser intensity, as distinguished from the apricot-yellow general color tonality of the flowers of this parent variety which tend to fade to cream color; the new variety is distinctly more upright in its habit of plant growth, as compared with the spreading habit of the parent variety; the new variety is substantially more dwarf in its habit of growth; and the foliage of the new variety is more glossy in contrast to the semi-glossy to non-glossy foliage of Yellow Pinocchio.

As compared with the pollen parent, Circus, the plant of our new variety is substantially lower growing in habit; the foliage is substantially more green in color and more glossy in appearance; the flowers are substantially smaller in size, particularly in general effect, and are rarely ever borne singly to the stern as is characteristic of this parent variety, this latter quality resulting in a more effective mass of bloom; and the flowers of the new variety are a uniform shade of yellow color, without other colors, as distinguished from the characteristic blend of red, pink, salmon, orange, and yellow colors of the flowers of Circus and which change in emphasis as the buds develop into open flowers.

Asexual reproduction of our new variety by budding, as performed at Chino, California, shows that the afore mentioned 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:
