Oh they do definitely grow here. Almost any of them, I just don't know enough about them to know if they would thrive out of a cultivated/cared for spot. I can do clay...oh my yes ...sand is out of the question unless I have it trucked in lol. We have clay with big rocks and an occasional patch of gravel, but the hillside in question is clay, mostly without rocks. It always makes me wonder what the heck was going on geologically to create this piece of land.
