    Avalon has a white trumpet on a yellow background. Simply stunning daffodil flower. New for me this past spring as I only planted them last fall. I can see that Avalon is going to be a favorite.
  • Posted by jmorth (central Illinois) on May 10, 2013 3:47 PM concerning plant:
    There are two entries for Avalon in the RHS's International Daffodil Register & Classified List.
    The other entry is a registered division 3 (small cup) daffodil w/ 1st flowering note of pre-1913 from England's A M Wilson. This second entry is described as a late season bloomer w/ a white perianth and a shallow, lightly frilled orange red corona (3 W - OOR).
