| Abstract: |
A miniature class rose plant having low compact dwarf spreading habit of growth, profusion of small white flowers in large clusters, dark green glossy foliage, resistance to rust and powdery mildew, ease of propagation by softwood cuttings and pleasant scent. |
| 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 itslow compact dwarf and spreading habit of growth, its constant and abundant production of pure white flowers, its dark green, glossy and very healthy foliage, its ease of propagation by softwood cuttings and its pleasant fragrance. |
| 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 the variety Petticoat, U.S. Plant Pat. No. 5,039, with the variety OrangeHoney, U.S. Plant Pat. No. 4,496.
The primary objective of this breeding was to produce a new rose variety having the spreading low growing habit of both Petticoat and Orange Honey but with the superior dark green, disease-resistant foliage of Petticoat, the fragrance of OrangeHoney and the flower size of Petticoat. The objective was substantially achieved along with other desirable improvements as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguishit from its parents, as well as from all other varieties of which I am aware:
1. Low, compact dwarf spreading habit of growth.
2. Profusion of small white flowers in large clusters.
3. Dark green, glossy foliage.
4. Resistance to rust and powdery mildew.
5. Ease of propagation by softwood cuttings.
6. Pleasant scent.
Asexual reproduction of this new variety by softwood cuttings, as performed at Wasco, Calif., shows that the foregoing characteristics and distinctions come true to form and are established 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 it is reasonably possible to make the same in a colorillustration 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 dictionarysignificance of color is indicated.
