Title: Antirrhinum plant named ‘AACOR01’

Description:
Latin name of the genus and species:  Antirrhinum majus.    
     Variety denomination: ‘AACOR01’. 
     BACKGROUND OF THE INVENTION 
     The new cultivar is a product of a planned breeding program. The new variety originated from a cross pollination of the seed parent, an unnamed, unpatented proprietary selection of  Antirrhinum majus  with the pollen parent a different unnamed, unpatented  Antirrhinum majus . The crossing was made during November of 2005, at a commercial greenhouse in New South Wales Australia. ‘AACOR01’ was discovered by the inventor, Graham Brown, a citizen of Australia, in New South Wales, at a commercial greenhouse during November of 2007. 
     Asexual reproduction of the new cultivar ‘AACOR01’ was first performed in New South Wales, Australia, at a commercial greenhouse by vegetative cuttings in November 2007. ‘AACOR01’ 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 ‘AACOR01’ 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 ‘AACOR01.’ These characteristics in combination distinguish ‘AACOR01’ as a new and distinct  Antirrhinum  cultivar:
         1. Compact, mounded plant habit.   2. Early flowering.   3. Flexible, non-brittle stems.       

     PARENTAL COMPARISON 
     Plants of the new cultivar ‘AACOR01’ are similar to the female parent in most horticultural characteristics. However, ‘AACOR01’ differs in producing a compact, mounding plant, whereas the seed parent has a trailing plant habit. Additionally, the seed parent flowers three weeks later than the new variety. 
     Plants of the new cultivar ‘AACOR01’ are similar to the male parent in most horticultural characteristics. However, ‘AACOR01’ differs in having a compact, mounded plant habit, whereas the pollen has a distinctively upright plant habit. 
     COMMERCIAL COMPARISON 
     ‘AACOR01’ can be compared to the commercial variety  Antirrhinum majus  ‘Balumdepur’ U.S. Plant Pat. No. 13,097. Plants of ‘Balumdepur’ are similar to plants of ‘AACOR01’ in most horticultural characteristics, however, ‘AACOR01’ produces a flower with a lighter color, and stems that are less brittle. 
    
    
     
       BRIEF DESCRIPTION OF THE PHOTOGRAPH 
       The accompanying photograph in  FIG. 1  illustrates in full color a typical plant of ‘AACOR01’ grown outdoors in Lompoc, Calif. This plant is approximately 6 months old, shown in a 6 inch 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.
