RO SE PLANT Filed Dec. 6 i973 United States Patent 3,647 ROSE PLANT Georges Alphonse Delbard, Paris, France, assignor to The Cunard-Pyle Company, West Grove, Pa. Filed Dec. 6, 1973, Ser. No. 422,147 Int. Cl. Atllh /00 US. Cl. Plt.25 1 Claim ABSTRACT OF THE DISCLOSURE A new and distinct variety of rose plant of the Flori bunda class which was originated by me by crossing the variety Zambra (Plant Patent No. 2,140) with an unnamed seedling whose parentage was [(Orleans Rose Goldilocks, Plant Patent No. 672)] X ("Unnamed seedling of Orange Triumph Floradora).

SUMMARY OF THE INVENTION My present invention relates to a new and distinct variety of rose plant of the Floribunda class which was originated by me by crossing the variety Zambra (Plant Patent No. 2,140) with an unnamed seedling whose parentage was also an unnamed seedling of Orleans Rose (unpatented) Goldilocks (Plant Patent No. 672 crossed with an unnamed seedling of Orange Triumph (unpatented) and Floradora (unpatented): Zambra (Plant Patent No. 2,140) X [(Orleans Rose Goldilocks) (Orange Triumph seedling Floradora)].

My objective in making these crosses was to produce a new and improved rose variety of vigorous yet compact growth habit, free and continuous flowering, superior weather tolerance, combined with a distinctive color different from all other varieties. I was successful in my objective as evidenced by the following combination of characteristics which are outstanding in my new rose:

1. A plant of unusual vigor and freely branched;

2. Compact, even growth habit of spreading form making a rounded bush as broad as it is high;

3. Flowers produced freely over the plant and continuously through the season;

4. An attractive bud opening with petals slightly cupped, of semi-doubleform maturing with the petals loosely rolled outward;

5. An attractive, distinctive pink color with shadings of yellow and red to give an overall coral effect;

6. Flowers occurring in clusters often of ten or more;

7. Abundant foliage covering the plant completely and having above average resistance to common garden rose diseases; and

8. Greater tolerance to extremes of winter and summer weather than the average for the Floribunda class.

When compared to its seed parent, my rose has more pink in the flower color and with less change of color during the life of the flower and has a more compact habit of growth with greater vigor and is more floriferous.

The unnamed seedling which was the pollen parent of my new rose had no commercial value but had merit for breeding because of its vigorous, compact growth, abundant foliage which was successfully transmitted to my new rose.

Asexual reproduction of my new rose by budding at West Grove, Pa., and Malicorne, France, showed that its characteristics and distinction come true to form and are established and transmitted through succeeding propagations.
