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 `DICquiet`, (U.S. Plant Pat. No. 8,900), with the variety `KORfullwind`, (U.S. Plant Pat. No. 8,872).
The primary objective of this breeding was to produce a new rose variety having the disease resistance and well-branched habit of the female parent combined with the disease resistance, glossy foliage, and spreading habit of the male parent. This cross was primarily designed to produce a low growing, well-branched, spreading floribunda. The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:
1. Well-branched, low growing, upright but spreading habit;
2. Small, many petalled flowers, borne in clusters;
3. Small, dark green, semi-glossy foliage;
4. Resistance to rust and powdery mildew.
JACbabl is a small, compact spreading floribunda. As the flowers open on the terminal of a branch, there is rapid bud break behind the flowers producing new flowers on short branches very quickly.
Asexual reproduction of this new variety by softwood cuttings, as performed at Wasco and Somis, 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 color illustration 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 dictionary significance of color is indicated.
