Abstract: A new and distinct variety of shrub rose plant having a unique combination of beautifully full flowers with petals arranged in perfect formation; flowers of deep magenta crimson; short, upright growth; strong fragrance; and resistance to disease.
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 beautifully full flowers with petals arranged in perfect formation; flowers of deep magenta crimson; short, upright growth; strong fragrance; and resistance to disease.
Description: The present invention relates to a new and distinct variety of shrub rose plant of the rosa hybrida class which was originated by me by crossing unnamed seedlings. The primary objective of this breeding was to produce a new shrub rose varietyhaving repeat flowering with old fashioned flowers of a crimson color. The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the newvariety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

1. Beautifully full flowers;

2. Petals arranged in perfect formation;

3. Flowers of a beautiful, deep magenta crimson;

4. Short, upright growth;

5. Strong fragrance; and

6. Disease resistance.

Asexual reproduction of this new variety by budding, as performed at Albrighton, Wolverhampton, England, shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted throughsucceeding propagations.

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 thesame in a color illustration of this character.

The following is a detailed description of my new rose cultivar color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinarydictionary significance of color is indicated.
