Comfry, comfry, comfry. I love this aspect to any fruit guild. I recently acquire some root stock online, and they have all taking and are awaiting planting at the farm. My only direct experience with a fruit guild was in KC, where I planted comfry, purple chive, daffodil and some crimson clover. Good luck and send me some cherries where producing!
