Description

Mountain Mints are a group of plants in the mint family that are native to North America and all areas of NC. The leaves have a strong minty fragrance when crushed and can be used in cooking and making teas. The densely packed clusters of flowers come in white to shades of purple and attract many pollinators in July to Sept. Most have pleasing foliage when not in bloom and make a great addition to any pollinator garden.

They grow in moist to dry well-drained soils in sun to partial shade with the best flowering occurring in sun. They can spread by rhizomes but are easily control if spreading is not desired. Use in naturalized areas, native/pollinator gardens or edible gardens. Many varieties are available to choose from.
