Description

The present invention relates to a new and distinct variety of rose plant of the floribunda class which was originated by me by crossing the variety TANweieke, U.S. Plant Pat. No. 4,844, with an unnamed seedling.

The primary objective of this breeding was to produce a new rose variety having low, dwarf growth; rich flowering; red color, and good resistance against disease. The objective was substantially 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 of which I am aware:

1. Very bright red flowers borne in large clusters;

2. Very glossy, dark green, disease-resistant foliage;

3. Vigorous, upright, well-branched growth habit;

4. Abundance of small thorns on all branches; and

5. Presence of heavily appendaged sepals.

Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., and Uetersen, Germany, shows that the foregoing 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 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 where ordinary dictionary significance of color is indicated.
