Shrub rose plant named KORfullwind

Abstract

Shrub rose plant having dark green, glossy, disease-resistant foliage; a compact spreading habit, rapid repeat blooming and attractive pink blooms in clusters.

Description

The present invention relates to a new and distinct variety of rose plant of the shrub class which was originated by me by crossing the variety KORweirim with the variety KORfalt.

The primary objective of this breeding was to produce a new rose variety having the vigor, health and ground covering habit of KORweirim and the larger flower and deep yellow flower color of KORfalt, along with its rapid reblooming ability. Except for the flower color, 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. Dark green, glossy foliage;

2. Low growing, spreading habit of growth;

3. Rapid rebloom;

4. Resistance to most major rose diseases; and

5. Attractive pink flowers borne in clusters.

Asexual reproduction of this new variety by budding and softwood cuttings, as performed at Wasco, Calif., and Sparrieshoop, Germany, 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.
