Peppermint will spread! I just learned from Rosemary Gladstar’s book that you should keep your different types of mint separate because they will intermingle and you will wind up with all kinds of mutt mints and they won’t be as medicinal. I have a mint bed with multiple mints. I’ll be changing that up this year!

You can grow peppermint in pots to keep it from spreading, but I’ve found that in my zone 5 climate, it doesn’t always come back the next year when grown in a pot.

One of my favorite things to do in the summer is put a sprig of peppermint – bruising the leaves by twisting them – into a pitcher of water in the refrigerator. So refreshing!
