When I first planted this mint, it was supposed to cover just a small muddy area that wouldn't grow any grass - boy, has it taken over. If I didn't keep pulling a little from the outside, think my whole backyard would be covered in it. Smells good though.
Wow, that would be nice to have in the yard. Wonder if it would choke out ferns. Think I had one fern plant that got placed out in the back yard, and now it covers the whole wooded section outside of the yard.
