How invasive is horehound?
My mum really wants me to grow some horehound (Marrubium) for her. I hear different things about the invasiveness factor. Apparently it is a noxious weed in TX- not sure about anywhere else. I don't want to plant it if it is terribly invasive- not after the difficult time I've had dealing with oregano-gone-wild, lol.
Do you grow it and has it been a problem for you? Spread by both seed and rhizome I assume?
