USPP16763P2 - Shrub rose plant named ‘AUSintense’ - Google Patents

Abstract

Shrub rose plant having large, cupped blooms of dark pink having a fruity fragrance with Old Rose and shiny foliage on arching growth.

Description

Genus and species: Rosa hybrida.

Variety denomination:‘AUSintense’.

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of a shrub rose plant named ‘AUSintense’ which was originated by me by crossing an unnamed, unpatented seedling 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 very free-flowering, healthy rose plant with dark pink blooms on a bushy, branching 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. Large cupped blooms of deep pink.
  • 2. Fruity fragrance with Old Rose.
  • 3. Shiny foliage on arching growth.

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

‘AUSintense’ has dark pink blooms on a taller shrub as compared with the apricot blooms of the unnamed seedling. ‘AUSintense’ has a fruit and Old Rose fragrance as compared to ‘AUSgold’ (U.S. Plant Pat. No. 8,688) which has yellow blooms with a tea fragrance.

Comparison with Similar Variety

‘AUSintense’ has rich, shiny green foliage and dark pink, large-cupped blooms as compared to ‘AUSguard’ (unpatented) which has paler foliage and shallow-cupped, paler blooms.

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.
