Title: Rose plant-- Auswhite

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct variety of shrub rose, seedling resulting from a definite effort to produce an improvement in this class of roses. 
     BRIEF SUMMARY OF THE INVENTION 
     Primary features of this new variety which connote a distinctive advance over existing types are the gross abundant and continual blooming taken with the perfection of the fully double flowers of an old-fashioned, more particularly apparent in the accompanying illustration of a specimen thereof. 
    
    
     BRIEF DESCRIPTION OF THE DRAWING 
     The drawing is a colour photographic representation of a new variety of flush of bloom taken substantially in side view and showing inflorescence in various stages, stems and foliage of the plant. 
    
    
     DETAILED BOTANICAL DESCRIPTION 
     The following is a detailed description of the new variety, colour terminology being in accordance with the &#34;Methuen Handbook of Colour&#34; published by Eyre Methuen Ltd (1963). 
     Variety denomination (in accordance with the UPOV Convention): Auswhite (Trade name The Swan). 
     Type: Hardy: bush; outdoor; seedling; for cut flowers and garden decoration. 
     Class: Shrub. 
     Propagation: Holds its distinguishing characteristics through succeeding propagations by budding. 
     The rose plant was grown at Albrighton, Nr. Wolverhampton, England and was derived as follows: 
     Female parent (Seed parent): Charles Austin. 
     Male parent (Pollen parent): Seedling×Iceberg. 
     The operation of the artificial pollination is therefore expressed by the following (Charles Austin×seedling×Iceberg). 
     The following observations are made of specimens grown outdoors in England.
