Description

LATIN NAME OF GENUS AND SPECIES

Rosa hybrida.

VARIETY DENOMINATION

‘AUSverse’.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct shrub rose plant which was originated by me by crossing two unnamed seedlings.

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new rose variety that is a disease-resistant, rich, dark crimson red rose with beautiful, full-petalled blooms with a powerful, old rose fragrance, that repeat flowers throughout the summer.

BRIEF SUMMARY OF THE INVENTION

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. Rick, dark crimson blooms that turn to a shade of rich purple;

2. Strong, bushy rather upright growth;

3. Repeat flowering; and

4. Very good disease resistance.

Asexual reproduction of this new variety by budding, as performed at Wolverhampton, England, shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF THE ILLUSTRATION

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.
