| Abstract: |
A hybrid tea rose variety having a vigorous, upright plant, petals which change in color from near white to dark red as blooms open, and little or no 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 vigorous, upright plant, photosensitive pigments aging from near white to dark red, and little to no fragrance. |
| Description: |
This present invention relates to a new and distinct variety of rose plant ofthe hybrid tea class which was originated by me by crossing the variety Sunfire, U.S. Plant Pat. No. 3,510, with the variety Spellbinder, U.S. Plant Pat. No. 3,571.
The primary objective of this breeding was to produce a new rose variety combining the photosensitive pigment characteristic of Spellbinder with more floriferous characteristic of the variety Sunfire. This 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. A vigorous, upright, hybrid tea plant.
2. Photosensitive pigment in the petals, changing from near white to dark red as the blooms open.
3. Little or no 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.
