Floribunda rose plant named `JACextra`

Abstract

Floribunda rose plant having long stems, high greenhouse cut flower production, flowers presented in clusters, good vase life, and a flower color in the light pink range.

Description

The present invention relates to a new and distinct variety of rose plant of the floribunda rose class which was originated by me by crossing the variety `INTERprince`, (U.S. Plant Pat. No. 8,102), with an unnamed seedling.

The primary objective of this breeding was to produce a new rose variety having long stems, high greenhouse cut flower production, flowers presented in clusters, good vase life, and a flower color in the light pink range. 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. Flowers presented in clusters of three to seven blooms;

2. Cut flower production of 160-170 stems/m.sup.2 of greenhouse;

3. Stems are long and strong, averaging 18-22 inches long;

4. Vase life is good at 11-12 days, and;

5. Flower color is an attractive, very pure pink.

Asexual reproduction of this new variety by budding, as performed at Wasco, 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.
