No mint is an evil plant. It smells wonderful, nice tea, easy to grow. But NEVER put it in a garden. The ************ grows as a weed eventually. Thick ropey vines underground. It spreads and snuffles out surrounding plants. Mint only in a pot unless you want a monster.
Fur, what kind of mint did that?? My grandmother always kept an herb grden with spearmint in it and I did too and never had a weed problem.
