Title: Rose plant named ‘POULcs010’

Description:
Botanical classification:  Rosa hybrida.    
   Variety denomination: ‘POULcs010’. 
   SUMMARY OF THE INVENTION 
   The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing between the female seed parent, an unnamed seedling, and the male parent named ‘Deltogo’, non-patented. The two parents were crossed during the summer of 1992 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘POULcs010’. 
   The new variety may be distinguished from its unnamed seed parent by the following combination of characteristics:
         1. The seed parent has salmon pink flowers while ‘POULcs010’ has a orange red flower color.   2. The seed parent is a more upright in growth habit while ‘POULcs010’ is low growing, compact floribunda.       

   The new variety may be distinguished from its pollen parent, ‘Deltogo’ by the following combination of characterictics:
         1. The pollen parent has an apricot blend flower color while flowers of ‘POULcs010’ are orange red.   2. ‘POULcs010’ is more compact than the pollen parent.       

   The objective of the hybridization of this rose variety was to create a new and distinct variety for garden use with unique qualities, such as:
         1. Uniform and abundant orange red flowers;   2. Vigorous, but compact growth when propagated both as a budded rose and on its own roots;   3. Disease resistance;   4. Attractive, dark colored foliage.       

   This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventors, and distinguish ‘POULcs010’ 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 during winter 1992-1993 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark. 
   ‘POULcs010’ was selected in the spring 1993 by the inventors as a single plant from the progeny of the aforementioned hybridization. 
   Asexual reproduction of ‘POULcs010’ by traditional budding and rooted cuttings was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in June 1993. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULcs010’ are true to type and are transmitted from one generation to the next.

   DETAILED DESCRIPTION OF THE VARIETY 
   The following is a description of ‘POULcs010’, as observed in its growth in a field nursery in Jackson County, Oreg. Observed plants are 2 years of age and were budded on to  Rosa multiflora  rootstock. 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 ‘POULac006’, a rose variety from the same inventors described and illustrated in U.S. Plant Patent application Ser. No. 10/342,702 (now abandoned) are compared to ‘POULcs010’ in Chart 1.
