We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
I would suspect that these would naturalize well, given the right damp, acidic and sunny location. (The cultivated blueberrys do not seem to naturalize.) In fact, I have a spot that might work well for them, but whether the soil there is acidic enough I do not know.
Come to think of it, if it were just right for them, they would probably be there already.
Up north, we have half a meadow of the lowbush kind naturalized for a hundred years, and many of the wild highbush, but the highbush ones have been sickly in the last couple of years. Not sure if it is acid rain (our part of the state gets the Midwestern industrial airborne ) or some new pest or what. This summer I plan to feed and fuss over them all and see if that helps.
Back home, in our more southerly former salt marsh, have just planted one of the scorned hybrid type as the wild ones do not produce enough in a small area. WE have damp, acid soil here, but the first ones I planted were in the lowest spot which got salt water flooding from a tidal pond which killed them. I fully expect to raise even more fat and healthy birds and squirrels on these blueberries....The squirrels get into the nets, but unfortunately do not strangle in them.
