Title: Calibrachoa plant named ‘Docalalnatropic’

Description:
Botanical designation:  Calibrachoa  X  hybrida.    
     Cultivar denomination: ‘DOCALALNATROPIC’. 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct cultivar of  Calibrachoa  plant, botanically known as  Calibrachoa  X  hybrida  and hereinafter referred to by the name ‘Docalalnatropic’. 
     The new  Calibrachoa  plant is a naturally-occurring whole plant mutation of a proprietary selection of  Calibrachoa  X  hybrida  identified as code number AA14-002732-006, not patented. The new  Calibrachoa  plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of the mutation parent selection in a controlled greenhouse environment in Rheinberg, Germany in May, 2018. 
     Asexual reproduction of the new  Calibrachoa  plant by vegetative terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2018 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 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 ‘Docalalnatropic’. These characteristics in combination distinguish ‘Docalalnatropic’ as a new and distinct  Calibrachoa  plant:
         1. Semi-upright to outwardly spreading, trailing and decumbent plant habit.   2. Vigorous growth habit.   3. Freely branching habit.   4. Early and freely flowering habit.   5. Large flowers with yellow-colored petals with random red purple-colored speckles.   6. Good garden performance.       

     The new  Calibrachoa  can be compared to plants of the mutation parent selection. Plants of the new  Calibrachoa  differ primarily from plants of the mutation parent selection in the flower color as plants of the mutation parent selection have red-colored flowers. 
     Plants of the new  Calibrachoa  can be compared to plants of  Calibrachoa  sp. ‘Docalalnarec’, not patented. In side-by-side comparisons, plants of the new  Calibrachoa  differ primarily from plants of ‘Docalalnarec’ in the following characteristics:
         1. Plants of the new  Calibrachoa  have slightly larger flowers than plants of ‘Docalalnarec’.   2. Plants of the new  Calibrachoa  and ‘Docalalnarec’ differ in flower color as plants of ‘Docalalnatropic’ have yellow-colored petals with random red purple-colored speckles whereas plants of ‘Docalalnarec’ have red purple-colored flowers with yellow-colored centers.   3. Plants of the new  Calibrachoa  have narrower sepals than plants of ‘Docalalnarec’.       

    
    
     
       BRIEF DESCRIPTION OF THE PHOTOGRAPHS 
       The accompanying colored photographs illustrate the overall appearance of the new  Calibrachoa  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 colors of the new  Calibrachoa  plant. 
       The photograph on the first sheet ( FIG. 1  of 2) is a side perspective view of a typical flowering plant of ‘Docalalnatropic’ grown in a container.

     DETAILED BOTANICAL DESCRIPTION 
     The aforementioned photographs and following observations, measurements and values describe plants grown during the spring in 13-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial  Calibrachoa  production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 1,500 lux. Rooted young plants were pinched one time three weeks after planting and were twelve weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Fifth Edition, except where general terms of ordinary dictionary significance are used.
