Title: Petunia plant named ‘PEHY0042’

Description:
Latin name of the genus and species of the plant claimed:  Petunia hybrida.    
     Varietal denomination: ‘PEHY0042’. 
     BACKGROUND OF THE NEW PLANT 
     The present invention comprises a new  Petunia , botanically known as  Petunia hybrida , and hereinafter referred to by the variety name ‘PEHY0042’. 
     ‘PEHY0042’ is a product of a planned breeding program. The new cultivar has small sized, blue with violet shade colored flowers, is medium, early to flower and has a trailing to semi trailing plant habit. 
     ‘PEHY0042’ originated from a hybridization made in October 2014 in a controlled breeding environment in Enkhuizen, The Netherlands. The female parent was the proprietary line ‘N4358-1’ (not patented). Compared to ‘PEHY0042’, it has a more upright plant habit, earlier flowering and a blue flower color with deep blue veins. 
     The male parent of ‘PEHY0042’ was the unpatented proprietary line ‘N4621-1’ (not patented), a plant with a similar plant habit, bit later flowering and a deep rose flower color. 
     The resulting seeds were sown in August 2015. ‘PEHY0042’ was selected as one flowering plant within the progeny of the stated cross in December 2015 in a controlled environment in Enkhuizen, The Netherlands. 
     The first act of asexual reproduction of ‘PEHY0042’ was accomplished when vegetative cuttings were propagated from the initial selection in January 2016 in a controlled environment in Enkhuizen, The Netherlands. 
     BRIEF SUMMARY OF INVENTION 
     Horticultural examination of plants grown from cuttings of the plant initiated in January 2016 and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘PEHY0042’ are firmly fixed and are retained through successive generations of asexual reproduction. 
     ‘PEHY0042’ 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. ‘PEHY0042’ 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 ‘PEHY0042’ directly from the inventor. 
     The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this  Petunia  as a new and distinct variety. 
    
    
     
       BRIEF DESCRIPTION OF THE PHOTOGRAPHS 
       The accompanying photographic drawings show typical flower and foliage characteristics of ‘PEHY0042’ with colors being as true as possible with an illustration of this type. The photographic drawings show in  FIG. 1  a flowering plant of the new variety and in  FIG. 2  a close-up of the flower. 
     
    
    
     DETAILED BOTANICAL DESCRIPTION 
     The aforementioned photographs were taken in April 2018 from plants growing indoor in 12 cm pots in Andijk, The Netherlands. These plants were approximately 11 weeks of age. 
     The plant descriptions and measurements were taken in September 2018 in Andijk, The Netherlands on approximately 20 week old plants that were growing in containers. 
     Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.
