ROSE PLANT Filed Nov. 22, 1965 United States Patent 2,710 ROSE PLANT Herbert C. Swim, Ontario, and O. L. Weeks, Chino, Calif.,

assignors to Swim and Weeks, Chino, Calif., a copartnership consisting of Herbert C. Swim and O. L.

Weeks Filed Nov. 22, 1965, Ser. No. 509,229 1 Claim. (Cl. Flt-25) The present invention relates to a new and distinct variety of rose plant of the floribunda Class, which was originated by us by crossing an unnamed and unpatented seedling of Circus (Plant Patent No. 1,382) X Gan nette (unpatented) with the variety known as Spartan" (Plant Patent No. 1,357).

As the result of this breeding, we have produced a new and improved 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 tall, upright and vigorous habit of growth, with cutting stems of good length when grown under greenhouse conditions;

(2) A pronounced reddish-purple color of the new growth and prickles;

(3) A more or less continuous production of flowers when grown under either greenhouse or garden conditions;

(4) A distinctive and attractive shape of the buds and flowers substantially as described and illustrated;

(5) A relatively small bud and flower size, with good flower petalage;

(6) Long lasting qualities of the flowers both on the plant and when cut; and

(7) A distinctive and attractive general color tonality of the flowers ranging between Strong Yellowish-Pink and Strong Reddish-Orange in the newly open flowers and becoming near Strong Reddish-Orange as the flowers mature.

In comparison with its unnamed seed parent, the new variety is upright in its habit of growth, instead of spreading; its stems are distinctively angled in appearance similar to those of Garnette and unlike the stems of the seed parent which show little evidence of this trait; the flowers have greater petalage and have substantially greater substance and lasting qualities; and the flower color may be generally described as orange instead of the typical bi-color of the seed parent in which the inner petal surfaces are bright yellow at the base and bright red over the remainder, While the reverse surface is dominantly deep pink.

As compared with its pollen parent, Spartan, the new variety is both distinctly upright and quite tall in its habit of growth while the parent is neither; the stems are distinctively angled but not found to any degree in this parent; the new growth is reddish-purple in color to a pronounced degree, while Spartan has only a small amount of this pigment in its new growth; at the cutting stage, the flower buds are long-pointed to urn-shaped instead of short-pointed like those of this parent; the flowers are smaller in size; and the flowers have greater petalage.

Asexual 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 Plant Pat. 2,710 Patented Feb. 7, 1967 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:
