ROSE PLANT Filed Feb. 11, 1959 WITNESS INVENTOR QQMMZQ WILLIAM ATTYS.

Uni sd S ates. P t n My present invention concerns a new and distinct variety of rose plant of the fioribunda class, and is the result of definite breeding efforts carried out by me since 1948 in my rose gardens at Sebastopol, California.

My new rose plant variety is a selected seedling developed by cross breeding of the seed parent Pinnocchio (Plant Patent No. 484) with the pollen parent Crimson Glory (Plant Patent No. 105) and the new variety has been reproduced asexually by me at Sebastopol, California, whereby its novel and distinctive characteristics have been found to hold true from generation to generation and to appear permanently fixed. Asexual reproduction of my new variety has been done by budding at Sebastopol, California, and at the present time extensive propagation of the new variety is being done at San J acinto, California.

The distinctive and unusual qualities of this new variety reside in the pompon type of its multi-colored flowers the colors of which change continuously from the bud to the full opened bloom; its prolific and continuous blooming habit; and its growth habit wherein the flowers appear in clumps on a low growing bush, whereby the continuously changing colors of the blooms produces a kaleidoscopic effect in the over-all blooming plant.

My new variety of fioribunda type of rose plant blooms profusely and continuously throughout the year, the many petals of its pompon type flower staying on the stem until the flower has completely bloomed out, or about two weeks, and the flower is fragrant throughout its life. The bud is a yellowish pink color when the sepals first divide and this color turns to an orchid pink when the petals begin to unfurl. When the flower is opened, the color is a rich yellow with a tinge of pink throughout, and as the flower matures or becomes older the petals turn more pink around the margins while the yellow color fades. As the age of the flower progresses the petals have red tips and margins with about half the petal being white and the other half red, the white being at the base of the petals and the red becoming deeper in color as it approaches the tips. The matured petals are translucent and when viewed from the back the red can be seen through the petals. In partial shade the flowers are of a slightly lighter color.

The lasting quality of the flowers is very good both on the plant and as a cut flower, and the flowers are not effected by wet or hot weather. Also the new variety has been carefully observed and tested both at Sebastopol and at San J acinto, California, and has been observed to be resistant to the common rose diseases, such as black spot, mildew and canker. No diseases have been observed in the trials and tests of this new variety, ,and it is therefore believed that resistance to commonrose diseases is inherent in the new variety. I i

Patented Nov. 17, 1959 Fig. 2 is a face view of a fully opened flower showing how the initial yellowish color fades to white inthe body of the petals and to a pale pink at the tips of the petals: Fig. 3 shows a face view ofa semi-mature flower showing the transition of color change from pale pink to a deeper pink in the petal margins and the outer portion of the petals; r a

Other features of novelty in my new variety of floribunda rose will appear more particularly in the following detailed description of. the new plant:

' Flower N Blooming habit: Continuously and profusely from early spring through latefall. I Size:-.Medium--about 2 inches'in diameter and about 1 inqhesdeen Form: Rather'flat and form does'not change as the flower matures. a a a Petalage: 37 to 40 petals in imbricated arrangementand of obovoid, pointed tip form. 7 Petaloids: 10 to 12 in number'and'of size. Peduncle: Sturdy and upright and from 2 to 3 inches in length. Texture: Soft. Appearance: Velvety. Discoloration: Begins to brown after full bloom matures.

Bud

Form: Semi-globular, urn shaped in form, diameter and depth approximately /2 inch.

Sepals: Upstanding, branched, and hooded over the bud. The bud opens slowly and the sepals curl back after the bloom. Sepals are of tomentose white color on the inside and are a reddish brown color outside.

Calyx: Pear shaped and does not split. Has slightly hairy aspect and is from A to /2 inch in both breadth and length.

1A to y; inch ill Peduncle: Erect, stout, about 2 to 3 inches long, and.

very slightly hairy. The color is green.

Genital organs Stamens:

Anrhers.--Approximately 30, A inch long and in whorled arrangement. Filaments.-% inch long and yellow in color. Pollen: Orange yellow in color. Pistils: Approximately 10 to 15 in number and 3 3 inch in length. Stigmas: Brownish color. Ovaries: Typical globose rose hypanthium, enclosing achenes. t

A new and distinct varietyof rose plant of the floribunda type, substantially as herein shown and described, characterized as to novelty by the continuously changing color of its blooms from bud to fully matured flower, whereby freshly opened buds are of pale yellow color with a tinge of pink throughout turning to semi-mature flowers having white petals with pink outer end portions which petal portions turn to a deeper pink and then to red margins as the flower comes to full maturity; and further characterized by its sturdy, relatively low growth habit, and by its continuous and profuse flowering habit from early spring until late fall.
