| Abstract: |
A shrub rose variety having large flowers, bushy plant, and distinctive yellow flowers. |
| 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 large flowers, bushy plant, and distinctive yellow flowers. |
| Description: |
The present invention relates to a new and distinct variety of shrub rose plant of the Rosa hybrida class whichwas originated by me by crossing the variety Charles Austin, with the variety Abraham Darby.
The primary objective of this breeding was to produce a new shrub rose variety having yellow, quartered, scented flower on a bushy plant which repeatedly flowers. The objective was substantially achieved along with other desirable improvementsas 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. Large flowers,
2. Bushy plant; and
3. Distinctive yellow flowers.
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. In one instance, color is noted in accordance with the R.H.S. Colour Chart of The Royal Horticultural Society, London, England.
