BOTANICAL DESIGNATION 
     
       Rosa hybrid  
     
     VARIETY DENOMINATION ‘Poulpah042’ 
     SUMMARY OF THE INVENTION 
     The present invention constitutes a new and distinct variety of miniature rose plant which originated from a controlled crossing between the female seed parent, an unnamed seedling, and the male pollen parent ‘Poulhi013’, U.S. Plant Pat. No. 15,044. 
     The two parents were crossed during the summer of 2003 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety, named ‘Poulpah042’, originated as a single seedling from the stated cross. 
     The new variety may be distinguished from its female seed parent primarily by flower color. ‘Poulpah042’ has salmon pink flowers while the seed parent has pink flowers. 
     The new variety may be distinguished from its male pollen parent primarily by flower color. ‘Poulpah042’ has salmon pink flowers while ‘Poulhi013’ has orange flowers. 
     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 salmon pink flowers;   2. Vigorous and compact growth;   3. Year-round flowering under glasshouse conditions;   4. Suitability for production from softwood cuttings in pots;   5. Durable flowers and foliage which make a variety suitable for distribution in the floral industry.       

     This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventor, and distinguish ‘Poulpah042’ from all other varieties of which we are aware. 
     As part of the rose development program, Mogens N. Olesen germinated the seeds from the aforementioned hybridization and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark. ‘Poulpah042’ was selected by the inventor as a single plant from the progeny of the hybridization in 2003. 
     Asexual reproduction of ‘Poulpah042’ by cuttings and traditional budding was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in 2004. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulpah042’ are true to type and are transmitted from one generation to the next. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWING 
       The accompanying color illustrations show, 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 ‘Poulpah042’. 
     
    
    
     DETAILED DESCRIPTION OF THE VARIETY 
     The following is a description of ‘Poulpah042’, as observed in its growth in glasshouses in Fredensborg, Denmark. Observed plants are 3 months of age and were cultivated in 12 cm pots. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 2001, except where common terms of color are used. 
     For a comparison, several physical characteristics of the rose variety ‘Poulpah037’, U.S. Plant Pat. No. 17,377. are compared to ‘Poulpah042’ in Chart 1.
