| Abstract: |
A miniature class rose plant having exceptionally long lasting pink flowers both on the plant and as a cut miniature rose, ease of propagation as a softwood cutting, uniform compact growth habit and resistance to powdery mildew. |
| 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 itsexceptionally long lasting flowers both on the plant and as cut flowers, its ease of propagation from softwood cuttings, its uniform compact growth habit, and its resistance to powdery mildew. |
| Description: |
The present invention relates to a new and distinct variety of rose plant of the miniature class which was originated by me by crossing an unnamed seedling, with the variety Red Minimo, U.S. Plant Pat. No. 5,770.
The primary objective of this breeding was to produce a new clean, pink pot rose variety which produces many flowers and buds having a very good keeping quality. The 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 we are aware:
1. Exceptionally long lasting flowers both on the plant and as a cut miniature rose.
2. Ease of propagation as a softwood cutting.
3. Uniform, compact growth habit.
4. Resistance to powdery mildew.
Asexual reproduction of this new variety by budding, as performed by us, shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.
The accompanyingillustration 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 this character.
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 color isindicated.
