USPP9010P - Shrub rose plant named Auswith - Google Patents

Abstract

A shrub rose having large, fully double rosette flowers that are repeat flowering, generally pale pink in color, the color of the petals varying on each flower.

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 AUSmary with an unnamed seedling.

The primary objective of this breeding was to produce a new shrub rose variety that is repeat flowering and has pink, old-fashioned-shaped 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. Paler pink flowers than either parent;

2. Fully double rosette flowers;

3. Large blooms; and

4. Petals varying in color on each flower.

Asexual reproduction of this new variety by budding, as performed at Albrighton, Wolverhampton, England, 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.

Claims (1)

I claim:

1. A new and distinct variety of rose plant of the shrub class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of its repeat flowering, large, fully double rosette flowers that are generally pale pink in color, the color of the petals varying on each flower.
