Highlights
If you want to see pollinators in action, plant native mountain mints. These tall perennials burst into white and green blooms for over a month in summer, and when they’re flowering, they’re absolutely covered in bees, butterflies, and even the occasional hummingbird. Brush against the leaves, and you’ll catch a whiff of minty freshness. Easy to grow, deer-resistant, and at home in sun or part sun, mountain mints are one of the most rewarding natives you can add to your garden. Scroll on to meet some native species.

Mountain mint is one of those native plants that makes you look like a pro, even if you’re new to gardening.
Where mountain mint shines in your yard
Mountain mint looks best when planted in clusters, where its foliage and white flowers can create a soft backdrop for brighter natives like coneflowers or blazing stars. Use it in pollinator gardens, meadow plantings, or mixed borders — anywhere you want movement, height, and a constant buzz of pollinators.
FAQs
Is mountain mint aggressive?
Mountain mint can grow quickly and take over a garden—this is called being ‘aggressive’—if given its preferred rich soil AND allowed to spread unchecked. Here are two ways to keep mountain mint in check:
- Pull up the edges of its rhizome roots so they don’t spread. (In my front yard garden, pulling up rhizome roots that spread too far in the spring can take 15 minutes.)
- Grab a shovel and dig up a clump in the spring. Plant this clump elsewhere, or give it away! (I’ve had success halving it every year after its third growing year.)
Aggressive plants are not always “bad.” If you have a large area to cover, picking plants that spread quickly helps fill out an area much faster than slower-growing plants. At the same time, if you have a smaller garden, aggressive plants like mountain mint will need spring-time vigilance, especially after their third year.
How to grow mountain mint
Mountain mint is one of those native plants that makes you look like a pro, even if you’re new to gardening. Plant it in full to part sun and give it average soil—nothing fancy needed. Once established, it can handle dry spells but does best with consistent moisture.
Most mountain mint species grow between 3 and 5 feet tall, making them perfect for the middle or back of a garden bed. In the fall, you can cut the stems back or leave them standing for winter interest and extra wildlife cover. Either way, mountain mint will come back strong each spring—no special care required.
Here’s a quick growing overview from NC State Extension:
Plant nerd fact
Want to support pollinators? This is your plant.
Mountain mint might just be the heavyweight champion of native plants for pollinators.
In a three-year Penn State study tracking which native flowers attracted the most pollinator visits, clustered mountain mint (Pycnanthemum muticum) came out on top—every single year.
As the researchers put it:
“The plant that was most attractive to pollinators was Pycnanthemun muticum [clustered mountain mint]…When it was in flower the plant seemed alive with activity. “
Native plants to pair with mountain mints
These native plants all thrive in the same full sun to part sun as mountain mint. Plant them together and enjoy flowers and pollinators throughout the growing season.
