Growing Mountain Mint: A Complete Profile
By Growing Home Greens Team · August 10, 2026
Mountain mint is a native perennial mint relative with an unusually strong mint flavor and aroma for its size, and it draws pollinators reliably whenever it’s in bloom.
Starting from seed, not runners
Transplanting is recommended, starting seed indoors 6 to 8 weeks before transplanting out in mid-to-late spring. Sprinkle the seed on the soil surface and tamp it in lightly rather than burying it, since it needs light to germinate. Space plants 12 inches apart in rows 18 inches apart. It’s hardy in zones 5-8.
More controlled than a running mint
Like other mints, mountain mint can spread if left unchecked, but starting it from seed rather than the running rootstock some mint-family plants spread by gives more control over where it ends up in the garden, at least initially.
Harvest for tea and dried arrangements
Leaves can be harvested throughout the growing season. For the best dried material, gather flowering tops and leaves in late summer, useful for tea, scenting potpourri, or as a fragrant addition to dried flower arrangements.
Mountain mint has no recorded companions or antagonists in our data. See the full companion guide for mountain mint for how it’s tracked. At 1 plant per square foot, it’s a good pollinator-support addition to the Garden Designer near flowering vegetables that benefit from extra pollinator traffic.
