CROSS-REFERENCE TO RELATED APPLICATION
The present application claims priority to European CPVO 2016/2374, filed Sep. 29, 2016.
ORIGIN OF INVENTION
This invention relates to a new and distinct variety of shrub rose plant named ‘AUSapply’, 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 variety suitable for cut-flower production with large flowers having around 100 petals and having an intense deep pink color.
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 blooms with around 100 petals and an even and intense shade of deep pink coloring.
Asexual reproduction of the new variety by budding as performed 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. ‘AUSapply’ may be asexually propagated by budding. The budding successfully occurred on the plant/rootstock Rosa Inermis for the observed plants.
COMPARISON WITH PARENTS
The maternal and paternal parents of ‘AUSapply’ are two unnamed seedlings. The new rose may be distinguished from its maternal parent, by the following combination of characteristics: the maternal parent is of a paler pink color with a smaller, more cupped bloom. The new rose may be distinguished from its pollen parent, by the following combination of characteristics: the paternal parent has a Hybrid Tea bloom formed of a brighter pink and no fragrance.
COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR
The closest commercially available cultivars to the new variety are the ‘AUSchris’ (U.S. Plant Pat. No. 24,462). The new rose may be distinguished from the ‘AUSchris’ based on the number of petals, which are far fewer in number (˜65 petals). It may also be distinguished by the fact that the ‘AUSchris’ bloom has a darker pink and the petals are of a uniform color on both sides, whereas the petals of ‘AUSapply’ are slightly paler on the reverse. Finally, the base petals of ‘AUSchris’ have a yellow spot, whereas the ‘AUSapply’ has a white spot.
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 ‘AUSapply’ specimens were made at the nursery at David Austin Roses Limited in Albrighton, Wolverhampton, United Kingdom. The following description is of 5 year-old rose plants of the new variety grown in a garden environment in Albrighton, Britain in the month of May. Phenotypic expression may vary with environmental, cultural and climatic conditions, as well as differences in conditions of light and soil.
