| Abstract: |
A floribunda class rose plant having continuous, heavy production of light pink, moderately scented flowers, a compact spreading habit of growth, resistance to powdery mildew and rose rust and a high level of tolerance to blackspot. |
| 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 heavy bloom production, continuous bloom production, unique very light pink color, good level of disease resistance, compact spreading habit and moderate scent. |
| 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 Jacjem, U.S. Plant Pat. No. 5,001, with the variety Jacink, U.S. Plant Pat. No. 4,089.
The primary objective of this breeding was to produce a new rose variety having the quite dwarf spreading habit of Jacjem but with the continuous bloom of Jacink. The objective was substantially achieved along with other desirable improvementsas 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. Continuous, heavy production of light pink, moderately scented flowers.
2. A compact spreading habit of growth.
3. Resistance to powdery mildew and rose rust and a high level of tolerance to blackspot.
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 description using terminology in accordance with the Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of coloris indicated.
