Floribunda rose plant named `JACout`

Abstract

A floribunda rose having a strong flower fragrance; ease of production by softwood and hardwood cuttings and by budding; vigorous, upright and well-branched growth habit; and distinctive, deep pink flower color.

Description

The present invention relates to a new and distinct variety of rose plant of the floribunda class which was originated by the inventor by crossing the variety JACum, U.S. Plant Pat. No. 5,002, with the variety JACdew, U.S. Plant Pat. No. 5,122.

The primary objective of this breeding was to produce a new rose variety having the fragrance and growth habit of the female parent combined with the disease resistance and vigor of the male parent. 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:

1. Upright, vigorous, well-branched growth habit;

2. Strong, sweet fragrance;

3. Distinctive, deep pink flower color; and

4. Ease of propagation by hardwood and softwood cuttings, as well as by budding.

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 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.
