DEB'S WILD CRABAPPLE (Malus)
  9/13/2012 Greenville, VA.  Deb sent pictures. There are at least 35 species of Crabapple and they hybridize easily.  Experts are not in agreement as to existing species.  A picture of the flowers in Spring would be nice but, I think, wouldn't help me much in taking it further. If this turns out to be something else than a Malus, I'd love to know.
