Intruder alert?

       In case there was ever any doubt.  For most of my life there were two types of  Snowdrop - single & double.
      Just don't ask how/when/where I discovered there were multiseveral more, even the double variety is varieties.  Al might have known.
      This is a clumps of variety S. J. Taylor.  Well most of them; but I fancy the single interloper will indicate how much difference there is without even adding colours.
