Abstract: A rose plant from the shrub class having upright free-flowering habit of growth, continuous flowering, dark green, semi-glossy foliage, ease of rooting as a softwood or hardwood cutting and profusion of glands on sepals, receptacle, and rachis.
Claim: I claim:

1. A new and distinct variety of rose plant of the shrub class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of itsvigorous upright habit of growth, its continuous production during the growing season of light red flowers, its dark green, semi-glossy foliage, its ease of production from softwood or hardwood cuttings and its profusion of glands on sepals, receptacle,and rachis.
Description: The present invention relates to a new and distinct variety of rose plant of the shrub class which was originated by me by crossing the variety Tanweieke, U.S. Plant Pat. No.4,844, with the variety Jacink U.S. Plant Pat. No. 4,089.

The primary objective of this breeding was to produce a new rose variety having the upright free flowering habit of growth of variety of Jacink of with the dark, glossy green foliage and orange-red flower color of Tanweieke. The objective wassubstantially achieved along 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 ofwhich I am aware:

1. Upright free-flowering habit of growth.

2. Continuous flowering.

3. Dark green, semi-glossy foliage.

4. Ease of rooting as a softwood or hardwood cutting.

5. Profusion of glands on sepals, receptacle and rachis.

Asexual reproduction of this new variety by budding and by softwood and hardwood cuttings, as performed at Wasco, Calif., shows that the foregoing 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 with color description using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except whereordinary dictionary significance of color is indicated.
