Hi,
I ordered Susquehana and Prolific last year. Received them as bareroot twigs, actually, just twigs as they didn't have any roots to speak of.
Anyways, after a few months and they both sprouted, I'm pretty happy about it. Comparing the leaves of both, the Susquehana definitely looks like a paw paw. However, the leaves of the Prolific look different.
Thanks for your opinions,
