Welcome to the forums!
I will admit I have not had a chance to look over the book, but am quite interested.
I planted a row of elderberries, serviceberries and pawpaws along one of my fences, and while waiting for the pawpaws to mature, we were still able to enjoy yummy pies and such from the copious elderberry production. Great plants to have around. And almost impossible to kill, so that’s a plus for me! 😜
Hope you enjoy your time here!
