ROSE PLANT Filed D60. 22, 1965 United States Patent 2,724 ROSE PLANT Herbert C. Swim, Ontario, and 0. L. Weeks, Chino, Calif.,

assignors to Swim and Weeks, Chino, Calif., a copartnership Filed Dec. 22, 1965, Ser. No. 515,706 1 Claim. (Cl. Plt.26)

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 known as Verona (Plant Patent No. 2,282) with the variety known as Escort (Plant Patent No. 2,436), the former being the seed parent and the latter being the pollen parent.

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

(1) Long and relatively straight flower stems as compared with other greenhouse varieties of the floribunda or polyantha classes;

(2) An ability to produce successive crops of flowers without delay under glass and without regard to the season;

(3) A distinctive and attractive flower shape, beginning at the bud stage and progressing to the fully open flower;

(4) Good flower petalage;

(5) A distinctive channelled shape of the flower petals, with the channelling becoming more pronounced as the petals age;

(6) Good flower substance, with consequent good lasting qualities both on the plant and as cut flowers; and

(7) A distinctive and attractive medium pink general color tonality of the flowers.

In comparison with its seed parent, Verona, the channelled shape of the flower petals of the new variety is not typical of the flower petals of the parent variety; the flower petals have substantially greater substance or stiffness which is easily recognized by comparing the feel of the petals of the respective varieties; the flowers of the new variety are medium pink in color rather than dainty light pink as in the case of Verona; and the flower color of the new variety has substantially less variation in intensity.

As compared with its pollen parent, Escort, the plant of the new variety is substantially larger at maturity; the channelled shape of the flower petals is not typical of this parent; and the medium pink flower color is substantially lighter than the dark red flower color of Escort.

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 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:

Outside-shiny and This description of a newly opened flower was made from a rose grown outdoors during the month of Novemher at Ontario, California:

C0 l0r.Outer petal: outside surfacewhite, tinged slightly green, at base for about /3 of petal, blending irregularly with pink at first, but becoming a fairly uniform color near Strong Purplish-Pink, Plate 7.5RP 7/10 at margins; inside surfacewhite, tinged with green, at base for about A of petal, somewhat abruptly becoming between Strong Purplish-Pink, Plate 7.5RP 7/ 10 and Deep Purplish-Pink, Plate 7.5RP 6/12, with whitish color at base sometimes following midrib and adjacent veins, irregularly and briefly. Intermediate petal: outside surfacewhite, with very slight greenish tinge, at base for about A of petal, blending or changing rapidly to near Strong Purplish Pink, Plate 7.5RP 7/ 10; inside surface-near white for about A of petal at base, rapidly blending or chang ing to near Strong Purplish-Pink, Plate 7.5RP 7/ 10, with deeper pink markings on veins near Deep Purplish-Pink, Plate 7.5RP 6/12. Inner petal:

outside surface near white for about A of petal at base, sometimes extending irregularly upward along midrib, but merging rapidly elsewhere to between Strong Purplish-Pink, Plate 7.5RP 7/10 and Deep Purplish-Pink, Plate 7.5RP 6/ 12, and being nearer the latter at margins; inside surfacenear white for about /5 of petal at base, blending rapidly to near Deep Purplish-Pink, Plate 7.5RP 6/ 12.
