Abstract:
A new and distinct variety of miniature rose with long lasting, novel pink flowers, and dark green and attractive foliage. It exhibits compact, uniform growth and flowering under greenhouse conditions when grown as a potted floral plant. The new variety propagates well from cuttings and by grafting. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Description:
Genus, species and variety denomination: The botanical classification of the new rose plant is  Rosa hybrida , variety denomination ‘KORcarill’. 
   BACKGROUND OF THE INVENTION 
   The new variety of miniature rose plant of the present invention originated from a controlled crossing in a breeding program between ‘KORlusma’, a non-patented rose and ‘KORkleiva’ described and illustrated in U.S. Plant Pat. No. 11,232 issued on Feb. 22, 2000. 
   The two parents were crossed and the resulting seeds were planted in a controlled greenhouse environment. The resulting seedlings exhibited distinctive physical and biological characteristics. The new rose plant was selected in June, 2000 as a single plant from the seedling beds due to its superior characteristics and asexually propagated for further evaluation. This new and distinctive miniature rose variety is named ‘KORcarill’. 
   SUMMARY OF THE INVENTION 
   The new rose plant may be distinguished from its seed parent, ‘KORlusma’, a variety by the same breeder, by the following combination of characteristics:
         1. The seed parent has flowers of Red Group 42A, while ‘KORcarill’ has hot pink colored flowers.   2. The flowers of ‘KORcarill’ are larger.       

   The new rose plant may be distinguished from its pollen parent, ‘KORkleiva’ by the following combination of characteristics:
         1. The pollen parent has cream white flowers while ‘KORcarill’ has hot pink colored flowers.   2. The flower diameter of ‘KORcarill’ is equal to or slightly larger.       

   The objective of the hybridization was to create a new and distinct rose plant with unique qualities, such as:
         1. Compact and uniform growth and flowering under greenhouse conditions when grown as a potted floral plant;   2. Abundant, long lasting, and attractive flowers on upright stems;   3. Resistance to diseases encountered in greenhouse and nursery culture; and   4. Suitability for production from softwood cuttings in floral and nursery containers;       

   This combination of traits is not present in prior rose cultivars. These objectives have been substantially achieved and distinguish ‘KORcarill’ from all other varieties of which we are aware. 
   As part of the rose development program, Tim-Hermann Kordes germinated the seeds from the aforementioned hybridization and conducted evaluations and observations on the resulting seedlings in a controlled environment in Sparrieshoop, Germany. Asexual reproduction of ‘KORcarill’ by softwood cuttings was first done Jul. 1, 2000 at the Rosa-Danica Nursery in Odense, Denmark. 
   This initial and other subsequent propagation conducted in controlled environments show that the foregoing and all other characteristics of ‘KORcarill’ come true to form and are transmitted through succeeding generations.

   DETAILED DESCRIPTION 
   The following is a description of ‘KORcarill’, as observed in its growth in glasshouses in Odense Denmark on plants of 12 weeks of age and in a field nursery in Sparrieshoop, Germany on plants of 1 year of age. 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 ‘KORmisso’, a rose variety from the same inventor described and illustrated in U.S. Plant Pat. No. 11,264 and issued on Mar. 7, 2000 are compared to ‘KORcarill’ in Chart 1.
