Thank you. I think this German fig is as you describe. I live in the Northeast United States in the state of Maine. We have typically had winter low temperatures of about -20F (-29C), though our lows keep getting warmer and warmer, with this past winter being only about 0F (-18C). We typically get snow before Christmas that lasts until early spring, though this year we started with 28" of snow which melted away completely and so our plants went into winter without snow.
If you can grow figs then I suspect that you can grow pawpaws and encourage you to do it. They can handle cold well, but if your growing season is at all short then seek out varieties that ripen quickly. Mine just barely ripen before the first frosts come.
