Abstract

Shrub rose plant having blush pink blooms, touched with apricot; rosette shaped flowers, distinctly quartered; free and continuous flowering; arching branches, providing a wide, mounding shrub; and pleasing fruity fragrance.

Description

Genus and species: Rosa hybrida.

Variety denomination: ‘AUSbonny’.

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of a shrub rose plant named ‘AUSbonny’ which was originated by me by crossing an unnamed seedling (not patented), with the variety ‘AUSgold’ (Golden Celebration), (U.S. Plant Pat. No. 8,688).

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new rose variety being very robust and healthy, very free flowering, having blush pink blooms touched with apricot, and a pleasing fruity fragrance.

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. Blush pink blooms, touched with apricot;
- 2. Rosette shaped flowers, distinctly quartered;
- 3. Free and continuous flowering;
- 4. Arching branches, providing a wide, mounding shrub;
- 5. Pleasing fruity 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

The subject variety differs from its male parent ‘AUSgold’ (Golden Celebration) in flower color (golden-yellow for ‘AUSgold’, blush pink for ‘AUSbonny’), and the large, cupped size of flowers of ‘AUSgold’ compared to the medium sized flowers of ‘AUSbonny’.

Comparison with Similar Variety

The closest variety known to me is‘AUSecret’, U.S. Plant patent application Ser. No. 09/947,252, filed Sep. 5, 2001 for which has soft pink blooms with greater petalage than the blush pink blooms of‘AUSbonny’.

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.
