Title: Rosa hybrida shrub named &#39;ausbreeze&#39;

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     The current application claims priority to a United Kingdom Breeder&#39;s Right Certificate Application No. AFP 5/2106 filed Nov. 18, 2008, the disclosure of which is incorporated herein by reference. 
     CLASSIFICATION 
     The present invention relates to a new  Rosa hybrida  shrub. 
     VARIETY DENOMINATION 
     The new plant has the varietal denomination ‘AUSbreeze’. 
     ORIGIN OF INVENTION 
     This invention relates to a new and distinct variety of shrub rose plant named ‘AUSbreeze’, which was originated by crossing two unnamed, unpatented varieties of  Rosa hybrida.    
     BACKGROUND OF THE INVENTION 
     The primary objective of this breeding was to produce a flowering variety having medium soft pink blooms in a rosette formation with strong arching growth and a fruity fragrance. 
     SUMMARY OF THE INVENTION 
     Among the features which distinguish the new variety from other presently available and commercial rose cultivars known to the inventor is the following combination of characteristics: blooms that are a very pure soft pink in a perfect rosette formation having a fresh, fruity fragrance with hints of raspberry and tea. In addition, the growth is vigorous, tall and elegant with flowers produced along the stem. 
     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. ‘AUSbreeze’ may be asexually propagated by budding and grafting. The budding and grafting successfully occurred on the plant/rootstock  Rosa  cv. ‘Dr. Huey’ in the United States and on the plant/rootstock  Rosa dumetorum  cv. ‘Laxa’ in the United Kingdom. 
     COMPARISON WITH PARENTS 
     The new rose may be distinguished from its seed parent, by the following combination of characteristics: whereas the seed parent has yellow blooms with few petals, ‘AUSbreeze’ produces a pure soft pink bloom. The new variety is classified as a  hybrida  rose and has a vigorous, elegant arching growth. 
     The new variety may be distinguished from its pollen parent, by the following combination of characteristics: whereas the pollen parent bears small yellow blooms with few petals, ‘AUSbreeze’ bears larger blooms having many petals with a pure soft pink color. 
     COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR 
     The closest commercially available cultivar to the new variety is the ‘AUSgrab’ (unpatented variety). The new rose may be distinguished from the ‘AUSgrab’ variety by the following combination of characteristics: the ‘AUSgrab’ has a shorter growth and a deeper pink color compared to ‘AUSbreeze’, which has a taller growth and a paler pink color. In addition, the ‘AUSgrab’ variety has an Old Rose fragrance, while the ‘AUSbreeze’ has a fruity fragrance. 
    
    
     
       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.
