| Abstract: |
Floribunda rose capable of very high production of white blooms in a greenhouse and which have a long vase life. |
| 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 ofits very high production of stems per m.sup.2 of greenhouse, its long vase life, its small thorns and its overall high vigor and ease of production as a cut flower. |
| Description: |
The present inventionrelates to a new and distinct variety of rose plant of the Floribunda class which was originated by me by crossing the variety KORenlo, U.S. Plant Pat. No. 5,679, with the variety KORampa, U.S. Plant Pat. No. 5,411.
The primary objective of this breeding was to produce a new rose variety having high production and a good vase life. The objective was substantially achieved along with other desirable improvements as evidenced by the following uniquecombination 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. Very high production in greenhouse of flowers (300 stems per m.sup.2)
2. Small thorns
3. Excellent vase life
4. High vigor and ease of production as a cut flower
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 descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of coloris indicated.
