Title: Pelargonium plant named ‘Pacbluebe’

Description:
Botanical designation:  Pelargonium crispum.    
     Cultivar denomination: ‘PACBLUEBE’. 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct cultivar of  Pelargonium  plant, botanically known as  Pelargonium crispum , and hereinafter referred to by the name ‘Pacbluebe’. 
     The new  Pelargonium  plant is a product of a planned breeding program conducted by the Inventor in Dresden, Germany. The objective of the breeding program is to develop new early and freely flowering  Pelargonium  plants with attractive flowers. 
     The new  Pelargonium  plant originated from a cross-pollination made by the Inventor in Dresden, Germany during the summer of 2006 of two unnamed proprietary selections of  Pelargonium crispum , not patented. The new  Pelargonium  plant was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Dresden, Germany during the spring of 2007. 
     Asexual reproduction of the new  Pelargonium  plant by vegetative terminal cuttings in a controlled greenhouse environment in Dresden, Germany since October, 2007 has shown that the unique features of this new  Pelargonium  plant are stable and reproduced true to type in successive generations. 
     SUMMARY OF THE INVENTION 
     Plants of the new  Pelargonium  have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype. 
     The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Pacbluebe’. These characteristics in combination distinguish ‘Pacbluebe’ as a new and distinct  Pelargonium  plant:
         1. Upright and uniformly rounded plant habit.   2. Moderately vigorous growth habit.   3. Freely basal branching habit.   4. Early and freely flowering habit.   5. Dark and light purple bi-colored flowers that are held above the foliar plane on strong peduncles.   6. Does not require cooling treatment for flower development.   7. Long flowering period.       

     Plants of the new  Pelargonium  differ primarily from plants of the parent selections in flower coloration. In addition, plants of the new  Pelargonium  are more uniform than plants of the parent selections. 
     Plants of the new  Pelargonium  can be compared to plants of the  Pelargonium crispum  ‘Pacburg’, disclosed in U.S. Plant Pat. No. 14,862. In side-by-side comparisons conducted in Dresden, Germany, plants of the new  Pelargonium  differed from plants of ‘Pacburg’ in the following characteristics:
         1. Plants of the new  Pelargonium  had narrower leaves and leaf petioles than plants of ‘Pacburg’.   2. Plants of the new  Pelargonium  had broader leaves than plants of ‘Pacburg’.   3. Plants of the new  Pelargonium  and ‘Pacburg’ differed in flower color.   4. Plants of the new  Pelargonium  had longer peduncles (umbel stems) than plants of ‘Pacburg’.       

    
    
     
       BRIEF DESCRIPTION OF THE PHOTOGRAPH 
       The accompanying colored photograph illustrates the overall appearance of the new  Pelargonium  plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new  Pelargonium  plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Pacbluebe’ grown in a container. 
     
    
    
     DETAILED BOTANICAL DESCRIPTION 
     The aforementioned photograph and following observations, measurements and values describe plants grown in 19-cm containers during the winter, spring and summer in a glass-covered greenhouse in Dresden, Germany and under cultural practices typical of commercial  Pelargonium  production. During the production of the plants, day temperatures averaged 16° C., night temperatures averaged 14° C. and light levels ranged from 15 kilolux to 100 kilolux. Plants were pinched six weeks after planting and were four months old when the photograph was taken and nine months old when the detailed description was taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
