Mountain Mint, Slender

Slender Mountain Mint (Pycnanthemum tenuifolium)

Slender Mountain Mint, or Pycnanthemum tenuifolium, is a delicate and aromatic perennial herb native to the eastern United States. Compared to its more robust relatives, this species is known for its fine, narrow leaves and slightly milder minty scent. It produces clusters of small white to pale pink flowers that attract a variety of pollinators, especially native bees and butterflies. Slender Mountain Mint is a great addition to pollinator gardens, meadows, and naturalized landscapes due to its more controlled spreading habit. This species thrives in dry to medium soils, making it an excellent choice for low-maintenance gardens, xeriscaping, or areas with poor water retention. Its medicinal properties, particularly for digestive support and respiratory relief, have been appreciated for centuries.

Key Characteristics

• Narrow, Slender Foliage
  True to its name, Slender Mountain Mint features fine, narrow leaves that are lighter and airier than other Mountain Mint species. This gives the plant a delicate, wispy appearance, making it perfect for softening the look of garden borders or filling in meadows.
• Milder Spreading Habit
  While some Mountain Mints spread aggressively, Slender Mountain Mint has a more moderate growth habit. It forms clumps over time without the tendency to overtake other plants, making it easier to manage in smaller gardens compared to species like Pycnanthemum muticum (Clustered Mountain Mint).
• Attracts Pollinators and Beneficial Insects
  Slender Mountain Mint is a valuable pollinator plant, drawing native bees, butterflies, and beneficial predatory insects. Its long bloom period from mid-summer through fall ensures nectar availability for insects late in the season.
• Medicinal Uses
  Traditionally, the leaves of Slender Mountain Mint have been used in teas for digestive support, respiratory issues, and colds. The plant also possesses mild antibacterial and anti-inflammatory properties, making it useful for minor health ailments.
• Thrives in Dry to Medium Soils
  This species is highly adaptable to dry, well-drained soils, performing well even in drought conditions. It’s an excellent candidate for xeriscaping, meadows, and low-maintenance gardens where water conservation is a priority.
