Abstract: Floribunda rose plant having blooms of a stable, bright red color, singly and in clusters; dark green, semi-glossy foliage; resistant to powdery mildew; and vigorous growth.
Claim: I claim:

1. A new and distinct variety of rose plant of the floribunda rose class substantially as herein shown and described, characterized particularly as to novelty by blooms of a stable,bright red color, blooming singly and in multiple, small clusters of three to five buds; dark green, semi-glossy foliage; resistance to powdery mildew; and vigorous plant growth.
Description: The presentinvention relates to a new and distinct variety of rose plant of the floribunda rose class which was originated by me by crossing two unnamed seedlings.

The primary objective of this breeding was to produce a new floribunda rose variety adapted to be grown in pots and having the bright red color, bud form and upright spreading habit of the unnamed female parent combined with the dark green,glossy foliage and clustering of buds and blooms of both the male and female parents, and the petal substance of the male parent. The objective was substantially achieved, along with other desirable improvements, as evidenced by the following uniquecombination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

1. Two to two and one-half inch, bright red flowers with very good petal substance;

2. Dark green, semi-glossy foliage;

3. Upright spreading habit; and

4. Clusters of buds in groups of three or more.

Asexual reproduction of this new variety by cutting propagation, as performed at Wasco and Somis, Calif., shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted throughsucceeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make thesame in a color illustration of this character.

The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except whereordinary dictionary significance of color is indicated.

Petalage.--Number of petals under normal conditions: 50-60.

Color.--The upper sides of the petals are close to Red Group 45A. The reverse sides of the petals are close to Red-purple Group 63A. The base of each petal is Orange-white Group 159D. The major color on the upper sides is close to Red Group45A.

Variegations.--An occasional near-white stripe along mid-vein of the petal.

Discoloration.--At the end of the first day: Red Group 46A. At the end of the third day: Red Group 45A with some black tone.





Form.--Moderately quilled.

Arrangement.--Slightly quartered to imbricated. Petaloids in the center are few (3 to 7) and small.

Persistence.--Drop off cleanly.

Lastingness.--On the plant: Long (about 14 days). As a cut flower: Fair (7 to 9 days).

Reproductive parts:

Anthers.--Size: Medium. Quantity: Many. Color: Yellow. Arrangement: Regular around styles.

Filaments.--Color: Yellow.
