Narrowleaf Mountain Mint: Pycnanthemum tenuifolium
Narrowleaf Mountain Mint
Pycnanthemum tenuifolium
A delicate, aromatic native perennial with clusters of small white flowers that attract an incredible diversity of pollinators. Narrowleaf Mountain Mint is an excellent choice for sunny gardens, meadow plantings, pollinator gardens, and other areas with well-drained soil.
Its slender, needle-like leaves give the plant a fine-textured appearance, while its clusters of tiny white flowers provide a long-lasting source of nectar for native bees, butterflies, beneficial insects, and other pollinators. When crushed, the foliage releases a refreshing minty aroma. Narrowleaf Mountain Mint is a wonderful addition to native plantings designed to maximize wildlife value while adding texture and seasonal interest to the garden.

Don't Worry If It Doesn't Flower Right Away:
Native perennials don't always flower their first year, and that's completely normal! Young plants often put much of their energy into developing a strong root system and establishing themselves in their new environment. Depending on the species, you may see limited or no flowering during the first growing season, with more substantial flowering beginning in year two and beyond.
Watering for Establishment:
For the best results, water your new plants regularly during their first 6 weeks after planting, particularly during periods of hot or dry weather. Narrowleaf Mountain Mint prefers well-drained soil and can tolerate drier conditions once established. Avoid keeping the soil consistently saturated, as excessive moisture can lead to root problems.
Plant for the future: The first year is about putting down roots. Give your native plants time to establish, and you'll be rewarded with stronger, more resilient plants in the seasons ahead.
Garden Use:
Great for pollinator gardens, sunny borders, meadow plantings, prairie-style gardens, and other areas with well-drained soil. Its fine-textured foliage pairs beautifully with native grasses and bold-flowering perennials. Plant in groups of several individuals to create a noticeable display and provide a concentrated nectar resource for pollinators.
WNS Note:
Pycnanthemum tenuifolium is a native perennial with exceptional wildlife value. Mountain mints are widely recognized for attracting a remarkable diversity of insect visitors, making them especially valuable additions to pollinator-focused gardens. Narrowleaf Mountain Mint's airy growth habit and narrow foliage also provide a softer textural contrast to broader-leaved native plants.
