Title: Calibrachoa plant named ‘Docalhusopin 19’

Description:
Botanical designation:  Calibrachoa  X  hybrida.    
     Cultivar denomination: ‘DOCALHUSOPIN 19’. 
     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 ‘Docalhusopin 19’. 
     The new  Calibrachoa  plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new freely branching and early-flowering  Calibrachoa  plants with numerous attractive flowers. 
     The new  Calibrachoa  plant originated from a cross-pollination made by the Inventor in July, 2016 in Rheinberg, Germany of a proprietary selection of  Calibrachoa  X  hybrida  identified as code number AA15-005956-002, not patented, as the female, or seed, parent with a proprietary selection of  Calibrachoa  X  hybrida  identified as code number AA14-007028-003, not patented, as the male, or pollen, parent. The new  Calibrachoa  plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination 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 ‘Docalhusopin 19’. These characteristics in combination distinguish ‘Docalhusopin 19’ 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 light red purple-colored petals with dark red purple-colored centers.   6. Good garden performance.       

     The new  Calibrachoa  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 the following characteristics:
         1. Plants of the new  Calibrachoa  have larger flowers than plants of the female parent selection.   2. Flowers of plants of the new  Calibrachoa  are lighter red purple in color than flowers of plants of the female parent selection.       

     The new  Calibrachoa  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 the following characteristics:
         1. Plants of the new  Calibrachoa  have larger flowers than plants of the male parent selection.   2. Flowers of plants of the new  Calibrachoa  are light red purple and dark red purple in color whereas flowers of plants of the male parent selection have red-colored flowers.       

     Plants of the new  Calibrachoa  can be compared to plants of  Calibrachoa  sp. ‘Mini Famous Red+Pink Eye’, not patented. In side-by-side comparisons, plants of the new  Calibrachoa  differ primarily from plants of ‘Mini Famous Red+Pink Eye’ in the following characteristics:
         1. Plants of the new  Calibrachoa  have thicker lateral branches than plants of ‘Mini Famous Red+Pink Eye’.   2. Plants of the new  Calibrachoa  have longer and darker green-colored leaves than plants of ‘Mini Famous Red+Pink Eye’.   3. Plants of the new  Calibrachoa  are more freely flowering than plants of ‘Mini Famous Red+Pink Eye’.   4. Plants of the new  Calibrachoa  have larger flowers than plants of ‘Mini Famous Red+Pink Eye’.   5. Plants of the new  Calibrachoa  and ‘Mini Famous Red+Pink Eye’ differ in flower color as plants of ‘Mini Famous Red+Pink Eye’ have lighter-colored flowers.   6. Plants of the new  Calibrachoa  have larger sepals than plants of ‘Mini Famous Red+Pink Eye’.

     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.
