Title: Calibrachoa plant named ‘USCAL42202’

Description:
Botanical designation:  Calibrachoa  sp. 
     Cultivar denomination: ‘USCAL42202’. 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct cultivar of  Calibrachoa  plant, botanically known as  Calibrachoa  sp. and hereinafter referred to by the name ‘USCAL42202’. 
     The new  Calibrachoa  plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan and Bonsall, Calif. The objective of the breeding program is to create new uniform and freely-branching  Calibrachoa  plants with unique and attractive flower coloration and good garden performance. 
     The new  Calibrachoa  plant originated from a cross-pollination made by the Inventor on May 8, 2011 in Higashiomi, Shiga, Japan of a proprietary seedling selection of  Calibrachoa  sp. identified as code number 11CJ22-03, not patented, as the female, or seed, parent with a proprietary seedling selection of  Calibrachoa  sp. identified as code number 11CJ32-01, not patented, as the male, or pollen, parent. The new  Calibrachoa  plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Bonsall, Calif. on May 24, 2012. 
     Asexual reproduction of the new  Calibrachoa  plant by terminal cuttings in a controlled environment in Bonsall, Calif. since May 25, 2012 has shown that the unique features of this new  Calibrachoa  plant are stable and reproduced true to type in successive generations. 
     SUMMARY OF THE INVENTION 
     Plants of the new  Calibrachoa  have not been observed under all possible environmental conditions and various 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 ‘USCAL42202’. These characteristics in combination distinguish ‘USCAL42202’ as a new and distinct  Calibrachoa  plant:
         1. Compact, upright to outwardly spreading and mounding plant habit.   2. Freely branching habit; dense and bushy appearance.   3. Freely flowering habit.   4. Violet-colored flowers with central purple-colored star pattern and yellow-colored throats.   5. Good garden performance.       

     The new  Calibrachoa  plant can be compared to plants of the female parent selection. Plants of the new  Calibrachoa  differ primarily from plants of the female parent selection in flower color as plants of the female parent selection have purplish pink-colored flowers. 
     The new  Calibrachoa  plant can be compared to plants of the male parent selection. Plants of the new  Calibrachoa  differ primarily from plants of the male parent selection in flower color as plants of the male parent selection have brownish purple-colored flowers. 
     Plants of the new  Calibrachoa  can be compared to plants of the  Calibrachoa  sp. ‘USCAL91001’, disclosed in U.S. Plant Pat. No. 23,232. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new  Calibrachoa  differed primarily from plants of ‘USCAL91001’ in flower color as plants of ‘USCAL91001’ had red purple-colored flowers with yellow-colored star-shaped pattern and centers. 
     Plants of the new  Calibrachoa  can also be compared to plants of the  Calibrachoa  sp. ‘USCAL56501’, disclosed in U.S. Plant Pat. No. 21,628. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new  Calibrachoa  differed primarily from plants of ‘USCAL56501’ in flower color as plants of ‘USCAL56501’ had violet-colored flowers with darker violet-colored centers.

     DETAILED BOTANICAL DESCRIPTION 
     The aforementioned photographs and following observations, measurements and values describe plants grown during the spring in 11.5-cm containers in a polyethylene-covered greenhouse and subsequently in an outdoor nursery in Bonsall, Calif. During the production of the plants, day temperatures averaged 24° C. and night temperatures ranged from 13° C. to 16° C. Plants were pinched two times and were six weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
