PYCNANTHEMUM tenuifolium (Mountain Mint, Slender) is a herbaceous perennial plant native to eastern North America. It is a member of the mint family (Lamiaceae) and shares some characteristics with other mountain mint species, including aromatic foliage and attractive clusters of flowers.
Slender Mountain Mint is a clump-forming perennial that typically grows to a height of 2 to 3 feet (60 to 90 cm) and has a spread of about 1 to 2 feet (30 to 60 cm). It has square stems and narrow, lance-shaped leaves that are green to grayish-green. The leaves emit a minty fragrance when crushed. This species is commonly found in open woodlands, meadows, and prairies. It prefers well-drained soils and is adaptable to a range of light conditions, from full sun to partial shade.
The flowers of Pycnanthemum tenuifolium are small and white, arranged in dense clusters at the top of the stems. The clusters form a rounded or flat-topped inflorescence similar to other mountain mint species. The flowers attract various pollinators, including bees, butterflies, and beneficial insects. Slender Mountain Mint typically blooms from mid- to late summer, with the flowering period lasting several weeks. The flowers provide a nectar source for pollinators during this time.
Slender Mountain Mint is highly valued for its ecological benefits. The nectar-rich flowers attract a wide variety of pollinators, including bees, butterflies, and other beneficial insects. It serves as an important food source and habitat for native insects.
Slender Mountain Mint is often used in native plant gardens, wildflower meadows, or naturalistic landscapes. It is suitable for attracting pollinators and beneficial insects. It can also be used in herb gardens or fragrance gardens due to its minty aroma.
