Shrub rose plant named ‘AUStiger’

Abstract

Shrub rose plant having soft pink blooms, touched with apricot; flowers in the form of shallow, incurved cups; upright, bushy shrub growth; and light myrrh fragrance.

Description

Genus and species: Rosa hybrida.

Variety denomination: ‘AUStiger’.

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of a shrub rose plant named ‘AUStiger’ which was originated by me by crossing an unnamed, unpatented seedling and the variety ‘AUSpoly’ (CHARLOTTE™), U.S. Plant Pat. No. 9,008.

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a very free flowering and healthy rose variety, having soft pink, cupped blooms on a narrow bushy shrub.

BRIEF SUMMARY OF THE INVENTION

The objective was subsantially 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. Soft pink blooms, touched with apricot.
  • 2. Flowers in the form of shallow, incurved cups.
  • 3. Upright, bushy shrub.
  • 4. Light myrrh fragrance.

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

‘AUStiger’ has less petalage and more upright growth than the seed parent. The pollen parent ‘AUSpoly’ has large yellow blooms compared with the medium soft pink blooms of ‘AUStiger’.

COMPARISON WITH SIMILAR VARIETY

‘AUSland’ (U.S. Plant Pat. No. 10,969) has soft pink blooms with less petalage than the apricot tinted blooms of ‘AUStiger’. ‘AUSland’ has less upright growth than ‘AUStiger’.

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.
