they are some in hatchie bottom, chaney lake, very few though, the deer will almost stand in front of them and wait for the fruit to get ripe, the first time that i saw one, i thought it was a pear.
We have them on a property i hunt in Grainger County. I have tried to transplant some with no luck. These grow on a shady creek bank. I also brought some fruit to a friend who after eating the fruit, dried the pit and planted them in buckets. They grew to about 6 inches but died. Not sure about buying them from a tree suplly.
Neat-sounding plant, although I don't recall ever seeing that type of fruit laying on the forest floor. I suppose that makes sense, because it sounds like something tasty!
I don't think I'd have the determination to get a plant like that established anywhere. The article claims that the Native Americans transplanted them. They were evidently a lot better at it than most folks nowadays, because it seems that no one else can move them around much.
