Title: Campanula plant named ‘BKPCMPNN’

Description:
Botanical designation:  Campanula portenschlagiana.    
     Cultivar denomination: ‘BKPCMPNN’. 
     PLANT BREEDER&#39;S RIGHTS APPLICATION INFORMATION 
     An European Community Plant Breeder&#39;s Rights application for the instant plant was filed by the Applicant/Assignee, Beekenkamp Plants B.V. of Maasdijk, The Netherlands on Mar. 8, 2021, application number 2021/0687. Foreign priority is not claimed to this application. 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct  Campanula  plant, botanically known as  Campanula portenschlagiana  and hereinafter referred to by the cultivar name ‘BKPCMPNN’. 
     The new  Campanula  plant is a product of a planned breeding program conducted by the Inventor in Kudelstaart, The Netherlands. The objective of the breeding program is to create new compact and freely-flowering  Campanula  plants with attractive flowers and good garden performance. 
     The new  Campanula  plant originated from an open-pollination in May, 2018 of  Campanula portenschlagiana  ‘Get Mee Purple’, not patented, as the female, or seed, parent with an unknown selection of  Campanula portenschlagiana  as the male, or pollen, parent. The new  Campanula  plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination grown in a controlled greenhouse environment in Kudelstaart, The Netherlands in May, 2019. 
     Asexual reproduction of the new  Campanula  plant by terminal vegetative cuttings in a controlled greenhouse environment in Kudelstaart, The Netherlands, since August, 2020, has shown that the unique features of the new  Campanula  plant are stable and reproduced true to type in successive generations. 
     SUMMARY OF THE INVENTION 
     Plants of the new  Campanula  plant have not been observed under all possible combinations of 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 ‘BKPCMPNN’. These characteristics in combination distinguish ‘BKPCMPNN’ as a new and distinct  Campanula  plant:
         1. Compact, upright to spreading and uniformly mounding plant habit.   2. Freely branching habit.   3. Freely flowering habit.   4. Purple-colored flowers.   5. Good container and garden performance.       

     Plants of the new  Campanula  differ primarily from plants of the female parent, ‘Get Mee Purple’, in the following characteristics:
         1. Leaves of plants of the new  Campanula  are more greyed green in color than leaves of plants of ‘Get Mee Purple’.   2. Flowers of plants of the new  Campanula  are positioned above the foliar plane whereas flowers of plants of ‘Get Mee Purple’ are positioned within and above the foliar plane.       

     Plants of the new  Campanula  can be compared to plants of  Campanula portenschlagiana  ‘Ambella’, not patented. In side-by-side comparisons, plants of the new  Campanula  differ primarily from plants of ‘Ambella’ in the following characteristics:
         1. Plants of the new  Campanula  are more compact and narrower than plants of ‘Ambella’.   2. Leaves of plants of the new  Campanula  are more greyed green in color than leaves of plants of ‘Ambella’.   3. Flowers of plants of the new  Campanula  are positioned above the foliar plane whereas flowers of plants of ‘Ambella’ are positioned within and above the foliar plane.       

    
    
     
       BRIEF DESCRIPTION OF THE PHOTOGRAPHS 
       The accompanying colored photographs illustrate the overall appearance of the new  Campanula  plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new  Campanula  plant. 
       The photograph on the first sheet ( FIG. 1 ) is a side perspective view of a typical flowering plant of ‘BKPCMPNN’ grown in a container.

     DETAILED BOTANICAL DESCRIPTION 
     Plants used for the aforementioned photographs and following description were grown in 10.5-cm containers during the spring in a heated glass-covered greenhouse in Maasdijk, The Netherlands and under cultural practices typical of commercial  Campanula  production. During the production of the plants, day temperatures ranged from 15° C. to 19° C. and night temperatures ranged from 13° C. to 15° C. Plants were ten weeks from planting rooted young plants when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
