How to grow

Grow in full sun or part shade with at least 6 hours of direct sun to keep stems sturdy and upright. Plants tolerate a wide variety of soil types from dry to wet. To prevent plants from expanding outside their allotted space, avoid planting in fertile soil.

Care and maintenance

While clustered mountain mint is vigorous, it can easily be kept in bounds by annually taking a spade and digging around the perimeter of the plant. The pieces outside the perimeter are at or just below the soil level and are easy to pull up.

Where to plant

Perfect for those tough spots that are too demanding for other plants to grow. Grow in meadows, on steep banks, and at the edge of woods, where less-than-ideal conditions will keep a check on its vigor.

When to plant

Spring and the fall are the best times, but they can be planted in the summer if plants are watered until they get established.


Depending on how fast you want plants to fill in, space plants between 2 to 5 feet apart.

When will my plant flower?

Plants shipped in winter and spring will flower in the summer.

Native habitat and range

Low meadows and in moist open woodlands. Native in scattered locations throughout most of the eastern United States.

Source and origin

Dormant plants can safely be kept in a basement, garage, or cool room until you are ready to plant in late winter or early spring.
