ROSE PLANT Filed Aug. 18, 1972 United States Patent I ii Plant Pat. 3,546 Patented May 7, 1974 ABSTRACTOF THE DISCLOSURE A rose plant of the fioribunda class originated by crossing Tamango (US. Plant Pat. No. 2,857) with an unnamed and unpatented rose seedling which resulted from a crossing of Fire King'(U.S. 'PlantPat. No. 1,758)

with Banzai (U.S. Plant Pat. No. 2,142).

SUMMARY OF THE INVENTION My invention relates to a new and distinct variety of rose plant of the fioribunda class which ,was'originated by me by crossing the rose known as Tamango (U.S. Plant Pat. No. 2,857) with an unnamed and unpatented rose seedling which resulted from a cross of Fire King (U.S. Plant Pat. No. 1,758) with Banzai (U.S. Plant Pat. No. 2,142). Tamango was the seed parent and the unnamed and unpatented seedling was the pollen parent.

As the result of this crossing, I have produced a new and useful rose variety-which is distinguished from its parents, and all rose varieties of which I am aware, as evidenced by the following unique combination of characteristics which are outstanding therein:

(1) A bushy, vigorous, much branched plant of average height for the class;

(2) Flowers of good form in bud and when fully developed with up to 50 velvety petalsof uniform, attractive red color; I

' (3) Continuous, abundant flower production for garden and landscape decoration as well as cut flowers for indoor use;

(4) Flowers produced singly on stems for cutting and in irregular clusters of several to the stem giving an attractive flowering effect;

(5) Abundant, 7 medium sized leaves of moderately glossy and smooth, moderately leathery texture with above normal resistance to disease for roses of this class; and

(6) Winter-hardiness above normal for garden roses of the fioribunda class.

My new variety is distinguished from its seed parent by deeper, more uniform red color of the flower and withthe flower newly opened averaging at least 10 more petals, so the reproductive parts of the flower are less conspicuous. New shoots and new leaves of my new variety are of more mahogany-red (general color term) than the seed parent With'mature foliage a deeper, bluer green (general color term) than the seed parent. -When compared to the pollen parent, my new rose has more vigorous, branched and taller growth characteristics with flowers of smaller size and much less tendency to have white streaks in the petals.

Reproduction of my new variety by asexual budding of several generations has been accomplished'in France and at West Grove, Pennsylvania, and at McFarland, California. The unique combination of chracteristics of my rose have held true and consistent through these successive asexual propagations.

BRIEF DESCRIPTION OF DRAWING The accompanying drawing shows typical specimens of the vegetative growth and the flowers and reproductive parts of my new invention in various stages of develop ment and is depicted in color as nearly true as it is reasonably possible to have a color illustration of this character.

1. A new and distinct variety of rose plant of the fioribunda class, substantially as herein shown and described, characterized particularly as to novelty -by the unique combination of bushy, vigorous, much branched plant of medium height, flowers with petals arranged in regular and pleasing form in all stages of maturity and with uniform red color from one petal to the next regardless of the maturity of the flower; with these flowers borne continuously and abundantly, singly and in irregular clusters, several to the stem, with abundant foliage moderately glossy, smooth with moderately leathery texture with resistance to disease comparable to the average of roses of the floribunda class, and with winter hardiness more than typical for the class.
