Rose plant named `Ausclub`

Abstract

Rose plant of the shrub type having pink flowers paler than those of Mary Rose but darker than those of Chaucer and having glossy foliage.

Description

The present invention relates to a new and distinct variety of shrub rose plant of the Rosa hybrida class which was originated by me by crossing the variety Mary Rose, with the variety Chaucer.

The primary objective of this breeding was to produce a new shrub rose variety having pale, pink, quartered, scented flowers on a bushy plant and which repeat flowers. The objective was substantially achieved along with other desirable improvements as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents, as well as from all other varieties of which I am aware:

1. Paler pink flowers than Mary Rose;

2. Darker flowers than Chaucer; and

3. Glossy foliage.

Asexual reproduction of this new variety by budding, as performed at Albrighton, 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 Methuen Handbook of Colour, except where ordinary dictionary significance of color is indicated.
