Abstract

A shrub rose having a vigorous, well-branched and upright habit of growth; dark green, glossy, disease-resistant foliage and attractive pink flowers; and being easily propagated from softwood cuttings.

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 KORmarie with an unnamed seedling.

The primary objective of this breeding was to produce a new rose variety having the shrub-like characteristics and healthy foliage of KORmarie combined with the very healthy foliage of the unnamed seedling. Flower color could be anything between the yellow-pink flowers of KORmarie and the red of the unnamed seedling. 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. A vigorous, upright, well-branched growth habit;

2. Dark green, glossy and healthy foliage;

3. Dark pink, lightly scented flowers; and

4. Ease of propagation from softwood cuttings.

Asexual reproduction of this new variety by 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.
