Many popular garden cultivars have a native equivalent, and mint is no exception. Wild mint grows along rivers and creeks across the northern hemisphere, enjoying sunny open spots with plenty of moisture. Pipilo's wild mint is sourced from seed collected along the Missoula area's wild creeks.
The taste is sweet and the smell is seriously delightful. I had a small pile of drying flower heads in my office for a few days so I could extract seeds, and the relaxing mint aroma filled the whole room.
Mints can be garden bullies, but it helps to remember that they follow the water. So, if you have large swaths of irrigated garden, you may end up with some spreading mint. Limit your extra irrigation to where you want the mint to stay to help keep it in check. Planting with other rhizomatous species will also keep them all a little more balanced. I recommend indian hemp, streamside daisy, showy milkweed, fireweed, and chamisso sedge. Wild mint is also a great companion with sneezeweed and hairy evening primrose. This is also a good candidate for container cultivation.
