| Abstract: |
A shrub rose plant having recurrent blooms; dwarf procumbent habit of growth; small, dark green, glossy, disease-resistant foliage; heavy production of glands on the peduncle; and ease of propagation by softwood cuttings. |
| Claim: |
I claim:
1. A new and distinct variety of rose plant of the shrub class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of itsrecurrent blooms; dwarf procumbent habit of growth; small, dark green, glossy, disease-resistant foliage; heavy production of glands on the peduncle; and ease of propagation by softwood cuttings. |
| Description: |
The present invention relates to a new and distinct variety of rose plant of the shrub class which was originated by me by crossing the variety KORimro, with the variety of MACminmo, U.S. Plant Pat. No. 7,319.
The primary objective of this breeding was to produce a new rose variety having the procumbent growth habit of the once-flowering female parent combined with the recurrent flowering of the male parent. The objective was substantially achievedalong with other 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. Dwarf procumbent habit of growth;
2. Dark green, glossy, disease-resistant foliage;
3. Recurrent bloom;
4. Presence of many glands on peduncles; and
5. Ease of propagation by softwood cuttings.
Asexual reproduction of this new variety by budding and by softwood cuttings, as performed at Wasco, Calif., shows that the foregoing characteristics and distinctions come true to form and areestablished and transmitted through succeeding propagations.
The accompanying 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 itis 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 descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of color isindicated.
