| Abstract: |
Hybrid tea rose characterized by excellent exhibition flower form, very vigorous upright growth habit, high garden flower production, photosensitivity in the flowers, sepals, receptacles and peduncles, and a light fruity fragrance. |
| 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 deep coral pink color on petal margins that softens in the flower center, its vigorous and high flower production, light fruity fragrance, reddish-maroon peduncles, sepals and receptacle, wherever these have been exposed to sunlight. |
| Description: |
This present invention relates to a new and distinct variety of rose plant of the hybrid tea class which was originated by me by crossing the variety Pristine, U.S. Plant Pat. No. 3,997, with thevariety Antigua, U.S. Plant Pat. No. 3,431.
The primary objective of this breeding was to produce a new rose variety having the bud and flower form of Pristine coupled with the increased flower production of Antigua. The objective was substantially achieved along with other desirableimprovements 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. Excellent exhibition flower form.
2. Very vigorous upright growth.
3. High garden flower production.
4. Photosensitivity in the flowers, sepals, receptacle, and peduncle.
5. A light fruity fragrance.
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.
