There's no such thing as a little patch of applemint! It gets about 4 feet tall in my patch and has crowded out all its buddies over the last few years. It is so great for butterflies and bugs and the birds eat the tiny seeds in the fall.
I would be happy to send you some, except it is buried in snow and ice now. Let me know in April when it is coming up and it will ship safely without getting frozen.
