Title: Calibrachoa plant named ‘KLECA19545’

Description:
Genus and species:  Calibrachoa  sp. 
     Variety denomination: ‘KLECA19545’. 
     BACKGROUND OF THE NEW PLANT 
     The present invention comprises a new and distinct variety of  Calibrachoa , botanically known as  Calibrachoa  sp., and hereinafter referred to by the variety name ‘KLECA19545’. ‘KLECA19545’ originated from a controlled cross in August 2016 in Stuttgart, Germany between the proprietary female  Calibrachoa  parent ‘CA-2015-6388’, (unpatented) and the proprietary male  Calibrachoa  ‘KLECA17003’, (unpatented). Progeny from the cross were planted and a single plant was selected in May 2017 in Stuttgart, Germany. 
     ‘KLECA19545’ has been found to reproduce true to type in successive generations of asexual propagation in Stuttgart, Germany via vegetative tip cuttings. 
     SUMMARY 
     The following are the most outstanding and distinguishing characteristics of ‘KLECA19545’ when grown under normal horticultural practices in Stuttgart, Germany.
         1. Orange-reddish flowers; and   2. A semi-upright plant habit.       

    
    
     
       DESCRIPTION OF THE PHOTOGRAPH 
       This new  Calibrachoa  plant is illustrated by the accompanying photograph of a plant grown outdoors in Stuttgart, Germany. The photograph shows the whole plant, including the flowers and foliage and buds. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photograph is of a plant that is 14-weeks-old, taken outdoors on Jun. 4, 2019 in Stuttgart, Germany. 
     
    
    
     DESCRIPTION OF THE NEW VARIETY 
     The following detailed descriptions set forth the distinctive characteristics of ‘KLECA19545’. The data which define these characteristics were collected from asexual reproductions carried out in Stuttgart, Germany. Data was collected on plants grown 18-weeks since potting in a greenhouse with no pinching or growth regulators. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 5 th  edition (2007).
