I understand there are both European and North American species of crabapples. What popularly available varieties of crabapple are New England natives?
Ed, I don't know that any of these is popular, let alone available in N.E. but the three Malus species considered to be native to N. America are M. coronaria, M. fusca, and M. ionensis.
Now what has gone on, in terms of genetic material from any of these being used in the development of modern cultivars, that's well beyond my expertise.
Don't forget Malus angustifolia.
I am not aware of any named cultivars of native crabapples.
Forestfarm offers two of the above
Malus fusca - Pacific Crabapple
Malus coronaria - Wild Sweet Crabapple
Coronaria seems the more promising of the two. No thorns and not "thicket" forming. Then again anything which can compete with the honeysuckle under the walnuts would be welcome. Both seem reasonably attractive.
Malus coronaria is an attractive tree. The fruits also smell sweet (hence the name) but are not palatable.
Malus ioensis var texana , or Blanco crabapple is a good one for down in Texas. It is indigenous to the Central Texas area.
