Abstract: A floribunda rose having a compact, upright and well branched growth habit. It has a high level of disease resistance and an early and rapid rebloom, and is easily propagated by budding and through softwood and hardwood cuttings.
Claim: I claim:

1. A new and distinct variety of rose plant of the floribunda class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination ofits compact, upright and well branched growth habit, its high level of disease resistance, its early and rapid rebloom and its ease of propagation both by traditional budding and by soft and hardwood cuttings.
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 JACjem, U.S. Plant Pat. No. 5,001, 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 compact growth habit and disease resistant foliage of JACjem, combined with the early and constant bloom of JACink. The objective was substantially achievedalong 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. Compact upright well branched habit of growth;

2. Resistance to common rose diseases powdery mildew and rust;

3. Early and rapid rebloom of pink flowers in large clusters;

4. Ease of propagation by softwood and hardwood cuttings.

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 descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except whereordinary dictionary significance of color is indicated.
