Abstract: A new and distinct variety of rose plant of the hybrid tea class, characterized particularly by its red-purple color; vigorous, upright, well-branched growth; strong, damask rose like fragrance; dark green, glossy foliage; and good disease resistance.
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 by its red-purple color; vigorous, upright,well-branched growth; strong, damask rose like fragrance; dark green, glossy foliage; and good disease
Description: The present invention relates to a new and distinct variety of rose plant of the hybridtea class which was originated by me by crossing the variety `JACum` (U.S. Plant Pat. No. 5,002), with an unnamed seedling (not patented).

The primary objective of this breeding was to produce a new rose variety combining the strong fragrance of the female parent with the glossy foliage and good disease resistance of the male parent. Flower color was expected to be somewherebetween the deep plum of the female and the light lavender of the male. The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in thenew variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

1. Vigorous, upright, well branched growth;

2. Dark green, glossy foliage;

3. Good disease resistance; and

4. Strong, damask rose like fragrance.

Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding 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 the same in a colorillustration of this character.

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