Title: Calibrachoa plant named ‘KLECA22491’

Description:
Genus and species:  Calibrachoa  sp. 
     Variety denomination: ‘KLECA22491’. 
     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 ‘KLECA22491’. ‘KLECA22491’ originated from a controlled-cross between the proprietary female  Calibrachoa  variety ‘KLECA12235’ (U.S. Plant Pat. No. 25,287) and the male  Calibrachoa  variety ‘KLECA17002’ (unpatented). 
     In August 2015, two  Calibrachoa  parental lines, the female variety ‘KLECA12235’ and the male variety ‘KLECA17002’ were crossed via a controlled cross in Stuttgart, Germany and seeds were obtained. The seeds were sown and plants were grown for evaluation. A single plant was selected in May 2016 and subsequently named ‘KLECA22491’. In June 2016, ‘KLECA22491’ was first vegetatively propagated by cuttings. ‘KLECA22491’ was found to reproduce true to type in successive generations of asexual propagation via cuttings. 
     SUMMARY 
     The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Stuttgart, Germany.
         1. Large, single white flowers; and   2. Semi-trailing plant habit.       

    
    
     
       DESCRIPTION OF THE PHOTOGRAPH 
       This new  Calibrachoa  plant is illustrated by the accompanying photograph which shows a close-up of the whole plant. The photograph is of a 10-week-old-plant grown in in Stuttgart, Germany in May 2019. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. 
     
    
    
     DESCRIPTION OF THE NEW VARIETY 
     The following detailed descriptions set forth the distinctive characteristics of ‘KLECA22491’. The data which define these characteristics were collected from asexual reproductions carried out in Stuttgart, Germany. Data was collected on 8-week old plants after transplant in Stuttgart, Germany May 2022. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 5 th  edition (2007).
