There's a fruit tree native to North America that I had never heard of until recently, and that I suspect is not especially well known.
And it's weird.
It's called a pawpaw. It's unrelated to the papaya, although that's where the name probably comes from.
It's the largest edible fruit native to north america (more american than apple pie)
The trees grow in clone clusters, but they can't self-fertelize, which means that they are *frequently* found without fruit.
They are pollinated by flies and beetles, which is also rare in edible fruits.
Anyway, I found a cluster of the trees growing not far from here, but no fruit.
