You may get more responses if you post this on the NJ discussions page (toward the top of the NJ swap page look for switch to discussions), the Natives, or Edible Landscape forums, but off the top of my head I can tell you Pawpaw (Asimina triloba) and at least some blueberries (Vaccinium) are native here. If you use the link below, you can specify either US or Connecticut native, and check the box for Edible Fruit/Medicinal Value as a starting point.
