| Abstract: |
Hybrid tea rose plant having strong, vigorous, upright growth habit; distinctive red and yellow bicolor flowers; dark green, glossy foliage, and free-flowering ability. |
| Claim: |
I claim:
1. A new and distinct variety of rose plant of the hybrid tea class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination ofits strong, vigorous, upright, grown habit; its distinctive bicolor flowers; its dark green, glossy foliage, and its free-flowering ability. |
| Description: |
The present invention relates to a new anddistinct variety of rose plant of the Hybrid tea class which was originated by the inventor by crossing the variety JAColite, U.S. Plant Pat. No. 4,167, with the variety Madras, U.S. Plant Pat. No. 4,460.
The primary objective of this breeding was to produce a new rose variety having the upright vigorous growth and excellent flower form of JAColite combined with the free-flowering ability of Madras and its rose pink color. The objective wassubstantially achieved along 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 ofwhich I am aware:
1. Vigorous upright growth habit;
2. Distinct bicolor flower;
3. Dark green glossy foliage;
4. Very free flowering.
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 descriptions using termninology in accordance with the Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of coloris indicated.
