Shrub rose plant named `Aussal`

Abstract

A shrub rose having medium, old-fashioned-shaped flowers that are repeat flowering, generally rich, clear 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 an unnamed variety with another unnamed variety.

The primary objective of this breeding was to produce a new repeat flowering shrub rose with 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. Very full, old-fashioned-shaped flowers.

2. Rich, clear pink flowers.

3. Bushy growth.

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