Shrub rose plant named Auspoly

Abstract

A shrub rose having full, double, orange/yellow flowers, repeat flowering, and bushy growth.

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 seedling with the variety "Graham Thomas."

The primary objective of this breeding was to produce a new shrub rose variety that is repeat-flowering and has yellow, 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. Orange/yellow flowers;

2. Repeat flowering;

3. Full, double flowers; and

4. Bushy growth.

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.
