Title: Begonia plant named ‘Have02’

Description:
Latin name of the genus and species:  Begonia elatior.    
     Variety denomination: ‘Have02’. 
     BACKGROUND OF THE INVENTION 
     The new cultivar is the result of a chance discovery in an existing population of  Begonia elatior  plants. The new variety originated as a naturally occurring, whole plant mutation of the parent variety, the unpatented commercial variety,  Begonia elatior  ‘Netja’. The new variety was discovered by the inventor in the Fall of 2007 at a commercial greenhouse in Maasland, the Netherlands. 
     After selecting and isolating the new cultivar, asexual reproduction of the new cultivar ‘Have02’ was first performed in the same commercial greenhouse by vegetative cuttings in the winter of 2008. ‘Have02’ has since produced several generations and has shown that the unique features of this cultivar are stable and reproduced true to type. 
     SUMMARY OF THE INVENTION 
     The cultivar ‘Have02’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. 
     The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Have02’. These characteristics in combination distinguish ‘Have02’ as a new and distinct  Begonia  cultivar:
         1. Large foliage, with an undulating margin.   2. Large flower size.   3. Distinctive light pink flower color.   4. Vigorous plants, growing to a large size.       

     PARENTAL COMPARISON 
     Plants of the new cultivar ‘Have02’ are similar to the parent ‘Netja’ in most horticultural characteristics. However, ‘Have02’ differs in producing larger foliage with an undulating margin and lighter pink flowers. Additionally, ‘Have02’ produces a larger overall plant size than ‘Netja’. 
     COMMERCIAL COMPARISON 
     Plants of the new cultivar ‘Have02’ are best compared to the parent variety. 
    
    
     
       BRIEF DESCRIPTION OF THE PHOTOGRAPH 
       The accompanying photograph in  FIG. 1  illustrates in full color a typical plant of ‘Have02’ grown in a greenhouse in Maasland, the Netherlands. This plant is approximately 10 weeks old, shown in a 10 cm pot. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
