Title: Shrub rose plant named ‘POULoesy’

Description:
SUMMARY OF THE INVENTION 
     The present invention constitutes a new and distinct variety of shrub rose plant which originated from a controlled crossing between an unnamed seedling and ‘La Sevillana’ (U.S. Plant Pat. No. 6,384, issued on Nov. 8, 1988). The two parents were crossed and the resulting seeds were planted in a controlled environment. The new variety is named ‘POULoesy’. 
     The objective of the hybridization of this rose variety for commercial culture was to create a new and distinct variety with unique qualities, such as: 
     1. Uniform and abundant flowers; 
     2. Strong even growth with a free branching habit; 
     3. Flowers with a light rose scent. 
     4. Glossy and disease resistant foliage which requires limited maintenance, making it ideal for use in landscapes. 
     The combination of qualities of this variety represents significant improvement over previously available commercial cultivars of this type and distinguishes ‘POULoesy’ from all other varieties of which we are aware. 
     As part of their rose development program, L. Pernille Olesen and Mogens N. Olesen germinated the seeds from the aforementioned hybridization and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark. 
     ‘POULoesy’ was selected by the inventors as a single plant from the progeny of the hybridization in Fredensborg, Denmark, in May of 1991. Asexual reproduction of ‘POULoesy’ by cuttings and tradtional budding was first done by L. Pernille and Mogens N. Olesen in Fredensborg, Denmark in August of 1991. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULoesy’ are true to type and are transmitted from one generation to the next. 
    
    
     BRIEF DESCRIPTION OF THE DRAWING 
     The accompanying color illustration shows as true as is reasonably possible to obtain in color photographs of this type, the typical characteristics of the buds, flowers, leaves, and stems of ‘POULoesy’. Specifically illustrated in the drawing: 
     1. Stem showing branches and the attachment of leaves, buds, and peduncles; 
     2. Flower bud, partially opened bud, and open bloom; 
     3. Flower petals, detached; 
     4. Sepals, receptacle, and pedicel; 
     5. A bare stem exhibiting thorns; 
     6. Leaves. 
    
    
     DETAILED DESCRIPTION OF THE VARIETY 
     The following is a description of ‘POULoesy’, as observed in its growth in a nursery in Jackson County, Oreg., on plants aged one year. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 1995, except where common terms of color are used. 
     For a comparison, several physical characteristics of the rose variety ‘POULrijk’, a shrub rose variety from the same inventors described and illustrated in U.S. Plant Pat. No. 12,519, are compared to ‘POULoesy’ in Chart 1.
