| Abstract: |
A miniature rose variety having compact, spreading plant with dwarf growth habit, yellowish buds opening to 21/2" white flowers, mild fragrance, resistance to powdery mildew, and many straight thorns. |
| Claim: |
I claim:
1. A new and distinct variety of rose plant of the miniature class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of itsdwarf plant, mildew resistance, thorny stems, white flowers with a mild fragrance. |
| Description: |
This present invention relates to a new and distinct variety of rose plant of the miniature class which wasoriginated by me by crossing the variety Bon Bon, U.S. Plant Pat. No. 3,555, with the variety Calgold, U.S. Plant Pat. No. 4,230.
The primary objective of this breeding was to produce a new rose variety combining the plant habit of Bon Bon with miniature characteristics of Calgold. This objective was substantially achieved along with other desirable improvements asevidenced 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. Its compact, spreading plant habit.
2. Dwarfness, mostly under two feet in height.
3. Yellowish buds opening to white, 21/2" flowers.
4. Mild fragrance.
5. Resistance to powdery mildew.
6. Many straight thorns.
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.
