I have property in zone 4a. It's in WI about thirty minutes south of Lake Superior. I had read that they have pawpaw at UW Madison so I bought five seedlings as an experiment. The first year two survived the winter. The next year one of them was hit by a mower and died. The survivor is still alive after five years.

Pawpaw reproduce sexually so this year I bought five more plants from a farm in Michigan. These were older than seedlings and not cheap. Anything to wed my lone pawpaw.

Ilk know in the spring if any survived the winter.
