Abstract

A variety of rose plant of the shrub class, named ‘AUScrowd’. The ‘AUScrowd’ is a variety of a rose shrub having vigorous roses on a broad, rounded shrub with dark green foliage. The shrub bears large, many-petalled rosette blooms of a deep pink and outer petals of each bloom that pale slightly over time and have a strong fruity fragrance.

Description

Genus and species: 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 ‘AUScrowd’.
ORIGIN OF INVENTION
This invention relates to a new and distinct variety of shrub rose plant named ‘AUScrowd’, which was originated from the cross-pollination of the two ‘unnamed’ and unpatented seedlings of Rosa hybrida.
BACKGROUND OF THE INVENTION
The primary objective of this breeding was to produce a rose shrub that bears vigorous roses on a broad, rounded shrub with dark green foliage. The shrub bears large, many-petalled rosette blooms of a deep pink and outer petals of each bloom that pale slightly over time and have a strong fruity fragrance.
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: large, many petalled blooms of deep pink, outer petals that pale over time, a strong fruity fragrance, a shapely, broad and rounded shrub having dark green foliage.
Asexual reproduction of the new variety by budding as performed in Albrighton, Britain shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding asexual propagations. ‘AUScrowd’ may be asexually propagated by budding. The budding successfully occurred on an unpatented plant/rootstock Rosa dumetorum ‘Laxa’ for the observed plants.
COMPARISON WITH PARENTS
The maternal and paternal parents of ‘AUScrowd’ are two unnamed seedlings. The new rose may be distinguished from its seed parent, by the following combination of characteristics: the seed parent has smaller, pale pink open-cupped blooms compared to the large, deep-pink, many petalled rosettes of ‘AUScrowd’. The new rose may be distinguished from its pollen parent, by the following combination of characteristics: the pollen parent has smaller, yellow open-cupped blooms, compared to the large, deep-pink, many petalled rosettes of ‘AUScrowd’.
COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR
The closest commercially available cultivar to the new variety are ‘AUSpike’ (U.S. Plant Pat. No. 30,924) and ‘AUSvibrant’ (U.S. Plant Pat. No. 20,960). Both ‘AUSpike’ and ‘AUSvibrant’ have a petallage of around 90, whereas the petallage of ‘AUScrowd’ is approximately 125. Also, when viewed from above, the shape of the bloom of both ‘AUSpike’ and ‘AUSvibrant’ is irregularly rounded, whereas the blooms of ‘AUScrowd’ are round. ‘AUSpike’ has a depth of bloom of 3.5 cm compared with 6 cm for ‘AUScrowd’. The petals of ‘AUSvibrant’ have a reverse which is paler than the inner side, whereas the petal reverse on ‘AUScrowd’ is the same shade as the inner side.
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 ‘AUScrowd’ specimens were made at the nursery in Albrighton, Wolverhampton, United Kingdom. The following description is of 1 year-old rose plants of the new variety grown in a garden environment in Albrighton, Britain in the month of July. Phenotypic expression may vary with environmental, cultural and climatic conditions, as well as differences in conditions of light and soil.
