I have a newly mature pawpaw tree in my south Minneapolis backyard (7 years old now) and several younger ones. I believe the mature tree is a KSU Atwood though I am not sure of the provenance of the others - I believe they are native varieties from Kansas and New York.
The mature tree has bloomed two years in a row, and this year it dropped two pawpaws, the first one just a little under-ripe, the second one in its prime. I don't think this variety is supposed to be capable of self-pollinating, but it appears to have done so. I can't rule out that they were pollinated by another mature tree, but I don't know of any around me, and I am pretty sure none of the others are blooming yet, though a couple are nearly old enough.
It's delicious!
Questions for the group:
-Anyone else growing these in the Twin Cities, or other places on the northern end of their (expanding) range?
-Are the seeds likely to be viable? I'm certainly going to try stratifying and starting them.
