Title: Pelargonium plant named ‘PECZ0026’

Description:
Latin name of the genus and species of the plant claimed:  Pelargonium  x  hortorum.    
     Varietal denomination: ‘PECZ0026’. 
     BACKGROUND OF THE NEW PLANT 
     The present invention comprises a new  Pelargonium,  botanically known as  Pelargonium  x  hortorum , and hereinafter referred to by the variety name ‘PECZ0026’. 
     ‘PECZ0026’ is a product of a planned breeding program. The new cultivar ‘PECZ0026’ has white colored inflorescences with single florets with fringed upper petals, held above medium green foliage, on an upright-mounding branched vigorous plant with fan-shaped leaves and very free flowering, sun and heat tolerant habit. 
     ‘PECZ0026’ originates from a self-pollination in a controlled breeding program made in July 2013, in a greenhouse in Enkhuizen, The Netherlands. The parent was an unpatented plant of  P.  x  hortorum  parentage identified as ‘PEL-AZ3241-01V’ with larger and rounder florets, as well as more petal pigmentation when compared to ‘PECZ0026’. 
     ‘PECZ0026’ was selected as one flowering plant within the progeny of the stated cross in May 2014 in a greenhouse in Enkhuizen, The Netherlands. 
     The first act of asexual reproduction of ‘PECZ0026’ was accomplished when vegetative cuttings were propagated from the initial selection in June 2014 in a greenhouse in Enkhuizen, The Netherlands. 
     BRIEF SUMMARY OF INVENTION 
     Horticultural examination of plants grown from cuttings of the plant initiated in May 2015 in Enkhuizen, The Netherlands and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘PECZ0026’ are firmly fixed and are retained through successive generations of asexual reproduction. 
     ‘PECZ0026’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, and day length. 
     A Plant Breeder&#39;s Right for this cultivar has not yet been applied for. ‘PECZ0026’ has not been made publicly available prior to the effective filing date of this application, notwithstanding any disclosure that may have been made less than one year prior to the effective filing date of this application by the inventor or another who obtained ‘PECZ0026’ directly from the inventor. 
     The following traits have been repeatedly observed and are determined to be the basic characteristics of the new variety. The combination of these characteristics distinguishes this  Pelargonium  as a new and distinct variety. 
    
    
     
       BRIEF DESCRIPTION OF THE PHOTOGRAPHS 
       The accompanying photographic drawings show typical flower and foliage characteristics of ‘PECZ0026’ with colors being as true as possible with an illustration of this type. 
       The photographic drawings show in  FIG. 1 , one flowering plant of the new variety and in 
         FIG. 2 , a close-up of an inflorescence. 
     
    
    
     DETAILED BOTANICAL DESCRIPTION 
     The plant descriptions and measurements were taken in Enkhuizen, The Netherlands in early June 2021 under natural light. These plants were approximately 16 weeks old and were grown in a 12 cm pot, in a greenhouse trial. The photographs were taken in June 2021. 
     Color references are made to The Royal Horticultural Society Colour Chart (RHS) 2001.
