Can anyone help? My neighbour, who is now in his seventies, moved down here many years ago from the Midlands, He often says to me he wishes he had brought some of his tree onions with him. He hasn't seen any in years, and I get the feeling he would love me to grow some in my lottie. However, I have never heard of them, have no idea where I could buy any or how big they get (trees?!), conditions.... you get the picture. I will send in big pic if I ever find any to grow. Thanks.
