It is not likely but I thought Redding Ca was the furthest north palm trees grew. There are new cultivars that grow much further north now.You’ve done research in this! I’ve just never heard of anyone growing pomegranates, here or in Massachusetts or Connecticut, where I’ve also lived. Seems it would take some special handling. Like maybe a greenhouse! Could happen, I suppose. I don’t know where she is in Maine.
Pomegranates are possible but not likely
