| Abstract: |
A floribunda rose variety having a vigorous plant, large foliage, pink blooms having approximately 45 petals, slight fragrance, absence of prickles, long vase life, and good resistance to rose powdery mildew. |
| Claim: |
I claim:
1. A new and distinct variety of rose plant of the floribunda class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination ofvigorous greenhouse growth, stems without prickles, rose pink buds and blooms, exceptional vase life, slight fragrance and resistance to rose powdery mildew. |
| Description: |
This present invention relates to anew and distinct variety of rose plant of the floribunda class which was originated by me by crossing an unnamed variety with an unnamed variety.
The primary objective of this breeding was to produce a new rose variety especially suitable for use as a producer of cut flowers having no thorns, very long vase life, and attractive color. This objective was substantially achieved, along withother desirable improvements, as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents, as well as from all other varieties of which I am aware:
1. A vigorous plant.
2. Large, dark green foliage.
3. Good resistance to rose powdery mildew.
4. Rose pink blooms of approximately 45 petals.
5. Very slight fragrance.
6. Exceptionally long vase life -- 10 to 14 days commonly.
7. Absence of prickles.
Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.
Theaccompanying 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 the same in a color illustration of thischaracter.
The following is a detailed description of my new rose cultivar with color in terminology in accordance with The Royal Horticultural Society Colour Chart except where ordinary dictionary significance of color is indicated.
