Sorry, no pics, but wait, there's more. Don't leave yet!
Long ago before the time of digital cameras in our pockets, there was this bush growing near Wrights Ferry Baptist Church in Knoxville, TN.
Every year it produced giant round fruit that looked like Breadfruit. I have no clue whether or not it was edible and never tried one. However, the local hillbillies gave it assorted names like "the pineapple tree," "hillbilly handgrenade fruit," "prickly pawpaw," etc.
It is obviously not breadfruit since the leaves were small and they get snow there. It is obviously cold tolerant.
The bush was cut down many years ago. Wasn't any more than 8' height.
Really wish I knew what it was. I only have childhood memories of it.
