Title: Calibrachoa plant named ‘Docalhure’

Description:
Botanical designation:  Calibrachoa parviflora.    
     Cultivar denomination: ‘DOCALHURE’. 
     STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR AND APPLICANT 
     The Inventor and Applicant assert that no sales, publications or advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor and/or the Applicant. Inventor and Applicant claim a prior art exemption under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date. 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct cultivar of  Calibrachoa  plant, botanically known as  Calibrachoa parviflora  and hereinafter referred to by the name ‘Docalhure’. 
     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 large and attractive flowers. 
     The new  Calibrachoa  plant originated from a cross-pollination made by the Inventor in July, 2017 in Rheinberg, Germany of a proprietary selection of  Calibrachoa parviflora  identified as code number AA16-079056-004, not patented, as the female, or seed, parent with a proprietary selection of  Calibrachoa parviflora  identified as code number AA16-101068-001, 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, 2019. 
     Asexual reproduction of the new  Calibrachoa  plant by vegetative terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2019 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 ‘Docalhure’. These characteristics in combination distinguish ‘Docalhure’ as a new and distinct  Calibrachoa  plant:
         1. 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 red-colored petals with deep purplish red-colored centers and greenish yellow-colored throats.   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 flower color as plants of the new  Calibrachoa  have red-colored petals with deep purplish red-colored centers and greenish yellow-colored throats whereas plants of the female parent selection have dark red-colored flowers. 
     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 flower color as plants of the new  Calibrachoa  have red-colored petals with deep purplish red-colored centers and greenish yellow-colored throats whereas plants of the male parent selection have red-colored flowers. 
     Plants of the new  Calibrachoa  can be compared to plants of  Calibrachoa  sp. ‘USCAL08501’, disclosed in U.S. Plant Pat. No. 24,503. In side-by-side comparisons, plants of the new  Calibrachoa  differ primarily from plants of ‘USCAL08501’ in the following characteristics:
         1. Plants of the new  Calibrachoa  are more compact than and not as vigorous as plants of ‘USCAL08501’.   2. Plants of the new  Calibrachoa  are more freely flowering than plants of ‘USCAL08501’.   3. Plants of the new  Calibrachoa  differ primarily from plants of ‘USCAL08501’ in flower color as plants of the new  Calibrachoa  have red-colored petals with deep purplish red-colored centers and greenish yellow-colored throats whereas plants of ‘USCAL08501’ have dark red-colored flowers with large dark purple-colored centers and venation and yellow green-colored throats.

     DETAILED BOTANICAL DESCRIPTION 
     The aforementioned photographs and following observations, measurements and values describe plants grown during the spring and summer in 22-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 4,500 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, 2007, except where general terms of ordinary dictionary significance are used.
