Title: Calibrachoa plant named ‘KLECA18501’

Description:
Genus and species:  Calibrachoa  sp. 
     Variety denomination: ‘KLECA18501’. 
     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 ‘KLECA18501’. ‘KLECA18501’ originated from a controlled cross between the proprietary female  Calibrachoa  parent ‘CA-2015-6360’, (unpatented) and the proprietary male  Calibrachoa  ‘CA-2015-6416’, (unpatented) in Stuttgart, Germany in August 2015. 
     ‘KLECA18501’ has been found to reproduce true to type in successive generations of asexual propagation in Stuttgart, Germany via vegetative stem cuttings. 
     SUMMARY 
     The following are the most outstanding and distinguishing characteristics of ‘KLECA18501’ when grown under normal horticultural practices in Stuttgart, Germany.
         1. Vivid orange-red flowers; and   2. A semi-upright 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, unless otherwise noted, 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 whole plant photo of ‘KLECA18501’, 10-weeks-old, taken in April 2017. 
     
    
    
     DESCRIPTION OF THE NEW VARIETY 
     The following detailed descriptions set forth the distinctive characteristics of ‘KLECA18501’. 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).

     COMPARISON OF ‘KLECA18501’ WITH PARENTAL LINES AND KNOWN VARIETY 
     ‘KLECA18501’ is distinguished from the parental lines as follows. Whereas ‘KLECA18501’ has a vivid orange-red main lobe color, the female parent ‘CA-2015-6360’ has a yellow with red veins and red transition to corolla tube color and the male parent ‘CA-2015-6416’ has yellow with a red transition to corolla tube color. 
     ‘KLECA18501’ can be compared to the commercial  Calibrachoa  variety COLIBRI ‘Orange’ (patent status unknown) as follows. ‘KLECA18501’ flowers earlier and is more vigorous than COLIBRI ‘Orange’. Additionally, ‘KLECA18501’ is resistant to mildew,  Podosphaera xanthii , whereas COLIBRI ‘Orange’ has low susceptibility.
