| Abstract: |
A shrub rose variety having bright yellow flowers, quartered flowers, upright growth, and strong fragrance. |
| Claim: |
I claim:
1. A new and distinct variety of shrub rose plant of the Rosa hybrida class, substantially as herein shown and described, characterized particularly as to novelty by the uniquecombination of its bright yellow flowers, quartered flowers, upright growth, and strong fragrance. |
| Description: |
The present invention relates to a new and distinct variety of shrub rose plant of the Rosahybrida class which was originated by me by crossing the variety Graham Thomas, with the variety Yellow Button.
The primary objective of this breeding was to produce a new rose variety having yellow, quartered, scented flowers on a bushy plant which repeatedly flowers. The objective was substantially achieved along with other desirable improvements asevidenced 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. Bright yellow flowers;
2. Quartered flowers;
3. Upright growth; and
4. Strong fragrance.
Asexual reproduction of this new variety by budding, as performed at Albrighton, Wolverhampton, England, shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeedingpropagations.
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 acolor illustration of this character.
The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with the Methuen Handbook of Colour, except where ordinary dictionary significance ofcolor is indicated.
