Abstract

A variety of rose plant of the shrub class, named ‘AUSwasher’. The ‘AUSwasher’ is a variety of cut-rose rose with an unusual characteristic of large, green pistils protruding from the center of the quartered blossoms, with a strong fragrance and long vase life.

Description

Classification: The present invention relates to a new Rosa hybrida shrub of the market class ‘English Rose’.
Variety denomination: The new plant has the varietal denomination ‘AUSwasher.’
ORIGIN OF INVENTION
This invention relates to a new and distinct variety of shrub rose plant named ‘AUSwasher’, which was originated from the cross-pollination of the two ‘unnamed’ seedlings of Rosa hybrida.
BACKGROUND OF THE INVENTION
The primary objective of this breeding was to produce a variety of cut-rose rose with an unusual characteristic of large, green pistils protruding from the center of the quartered blossoms, with a strong fragrance and long vase life.
SUMMARY OF THE INVENTION
Among the features which distinguish the new variety from others presently available and commercial rose cultivars known to the inventor is the following combination of characteristics: green pistils protruding from the center of the bloom, quartered blooms, a strong old rose fragrance that develops into myrrh as the flower ages, and long vase life.
Asexual reproduction of the new variety by budding as performed in greenhouses at Bowling Green Lane in Albrighton, Britain shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding asexual propagations. ‘AUSwasher’ may be asexually propagated by budding. The budding successfully occurred on the plant/rootstock Rosa ‘Natal Briar’ (not patented) for the observed plants.
COMPARISON WITH PARENTS
The seed and pollen parents of ‘AUSwasher’ are two unnamed seedlings. The new rose may be distinguished from its seed parent, by the following combination of characteristics: the parent has blooms that are deeply-cupped pink which are smaller in size and the pistil do not protrude from the center of the bloom. The new rose may be distinguished from its pollen parent, by the following combination of characteristics: the parent has blooms that are pale apricot cupped flowers, again with no pistils protruding from the center of the bloom.
COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR
The closest commercially available cultivars to the new variety are the ‘AUSimmon’ (U.S. Plant Pat. No. 17,267). The new rose may be distinguished from the ‘AUSimmon’ variety by the following combination of characteristics: the ‘AUSwasher’ has pistils that protrude from the center of the bloom, whereas ‘AUSimmon’ does not, and also bears double blooms of a slightly deeper pink and green outer petals. ‘AUSimmon’ although a double bloom has fewer petals than ‘AUSwasher’.
BRIEF DESCRIPTION OF ILLUSTRATION
The accompanying photograph illustrates the new variety and shows the flowering thereof from bud to full bloom depicted in color as nearly correct as it is possible to make in a color illustration of the character. Throughout this specification, color references and/or values are based upon The Colour Chart of The Royal Horticultural Society (2001) except where common terms of color definition are employed.
 DESCRIPTION OF THE NEW VARIETY
Observations of budded ‘AUSwasher’ specimens were made at the nursery at David Austin Roses Limited in Albrighton, Wolverhampton, United Kingdom. The following description is of 1 year-old rose plants of the new variety grown in a greenhouse environment in Albrighton, Britain in the month of September. Phenotypic expression may vary with environmental, cultural and climatic conditions, as well as differences in conditions of light and soil.
