Abstract

Shrub rose plant suitable for cut flower production under greenhouse conditions, substantially as herein shown and described, characterized particularly by its upright growth, medium pink shallow cupped blooms having long vase life and moderate fruity fragrance.

Description

Genus and species: Rosa hybrida.
Variety denomination: ‘AUSimmon’.
ORIGIN OF THE INVENTION
The present invention relates to a new and distinct variety of a shrub rose plant named ‘AUSimmon’ 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 rose plant suitable for year round cut flower production under standard greenhouse conditions having medium pink, fragrant blooms with a long vase life, produced on strong, upright stems.
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. Medium pink, shallow cupped blooms having long vase life.
    • 2. Upright growth.
    • 3. Moderate fruity fragrance.
    • 4. Suitable for cut flower production under greenhouse conditions.
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
‘AUSimmon’ has large, medium pink blooms which differ from the smaller, cerise pink blooms of the seed parent and the bright crimson blooms and weaker fragrance of the pollen parent.
COMPARISON WITH SIMILAR VARIETY
‘AUSwith’ (U.S. Plant Pat. No. 9,010) has more petals and is pink with a tint of apricot, ‘AUSimmon’ is medium pink in color.
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
