Spell Czech (of sorts) for
sallyg:
The excellent Pawpaw research is ongoing at
Kentucky State University (KSU) in Frankfort KY, just down the road from the University of Kentucky (my alma mater). It's all good...
I agree with what others have already mentioned, and would add
Aronia melanocarpa and some of the minor native plum species, like
Prunus americana,
Prunus munsoniana, and
Prunus angustifolia.
And where would I be if I didn't recommend planting a few Viburnum? Many have quite flavorful albeit modest sized fruit. Good choices would include
Viburnum prunifolium,
Viburnum rufidulum,
Viburnum lentago, and
Viburnum sieboldii, among others.
