Abstract

Shrub rose plant substantially as herein shown and described, characterized particularly by blooms which start as peachy-pink cupped rosettes and which become domed, creamy-white blooms; a vigorous, well balanced and rounded shrub; and a light fragrance with strong notes of clove.

Description

Genus and species: Rosa hybrida.

Variety denomination: ‘AUSrelate’.

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of a shrub rose plant named ‘AUSrelate’ which was originated by me by crossing an unnamed, unpatented seedling with an unnamed, unpatented seedling.

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a repeat flowering healthy variety with creamy white blooms on a vigorous shrub.

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. Blooms which start as peachy-pink cupped rosettes and which become domed, creamy-white blooms.
- 2. A vigorous, well balanced and rounded shrub.
- 3. A light fragrance with strong notes of clove.

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

Comparison with Parents

The seed parent has single blooms and grey-green foliage compared with the double blooms and dark green foliage of ‘AUSrelate’. The pollen parent has apricot-orange blooms compared with the creamy-white blooms of ‘AUSrelate’.

Comparison with Similar Variety

‘AUSlevel’ (U.S. Plant Pat. No. 8,765) has more petals per bloom than ‘AUSrelate’ and has larger, less glossy foliage. ‘AUSrelate’ has a touch of apricot in its creamy-white blooms whereas ‘AUSlevel’ does not.

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.

DETAILED BOTANICAL DESCRIPTION

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 (2001), except where ordinary dictionary significance of color is indicated.
