Shrub rose plant named ‘AUSneil’

Abstract

Shrub rose plant suitable for cut flower production in greenhouse conditions having upright growth and white blooms with a hint of pink blush and strong myrrh fragrance.

Description

Genus and species: Rosa hybrida.

Variety denomination: ‘AUSneil’.

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of a shrub rose plant named ‘AUSneil’ 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 shrub rose plant suitable for year round cut flower production under standard greenhouse conditions having white blooms with a hint of blush, a strong myrrh fragrance and 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. White blooms with a pink blush.
  • 2. Upright growth.
  • 3. Strong myrrh 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

‘AUSneil’ has white blooms touched with a blush of pink and a strong myrrh fragrance which differs from the white blooms with no fragrance of the pollen parent and the pale pink blooms borne in small clusters of the seed parent.

Comparison with Similar Variety

‘AUSlevel’ (U.S. Plant Pat. No. 8,765) has a greater number of petals and is creamy white.

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.
