I agree - last year I grafted a Morello type sour cherry on P.
pennsylvanica - it had a good take and continued good growth this year. I
also made grafts of the same cherry on P. virginiana that didn't take at all.

I also agree that P. pennsylvanica might not be the ideal rootstock for a
cultivated cherry, but it can be an adequate temporary support to keep the
variety alive - and there are so many of them at my place, difficult not to
give it a try.
