Floribunda rose plant named `JACmebub`

Abstract

Floribunda rose plant having pure pink color; hard petal substance; production of large flowers in small clusters; being adaptable to greenhouse pot forcing; possessing a long shelf life; and dark green, semi-glossy, disease resistant foliage.

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 an unnamed seedling (unnamed seedling .times. Zorina, U.S. Plant Pat. No. 2,231), with the variety `POULnye`, U.S. Plant Pat. No. 8,942. The primary objective of this breeding was to produce a new floribunda rose variety having a pure pink color, hard petal substance, production of flowers in small clusters, adaptable to greenhouse pot forcing, possessing a long shelf life, and large flowers. 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. Pure pink color;

2. 21/2-3 inch flowers in small clusters;

3. Regularly producing flowers in small clusters;

4. Dark green, semi-glossy foliage;

5. Disease resistance;

6. Fragrance; and

7. Adaptable to greenhouse production

`JACmebub` was bred to be a rose that can be propagated by softwood cuttings, grown in pots in the greenhouse to produce a bud and bloom product for sale in 15-18 weeks time. It was also bred to grow well in the landscape, or as an outdoor pot plant. It achieves these goals quite well. Asexual reproduction of this new variety by cuttings, as performed at 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.
