OOOHHHH SO JEALOUS , my gotta do list hasn't allowed me to get very far in the garden yet….Love the heat tape thought….next week says a bit colder….My peppermint is in a huge clump in a sunny but wet (not soggy) area most of the year…..have a different type same kind of area but half sunny, grows like a weed……Comfrey grows anywhere, even in ditches near water…BEST in a confined container…..roots go DEEP and SPREADING. Even a fingernail size piece of root can grow…..i will be attempting to eliminate it from my garden forever. So i guess i'm saying, don't plant it where you may not want it in the future….
