Clustered Mountain Mint

Clustered Mountain Mint (Pycnanthemum muticum)

Clustered Mountain Mint, or Pycnanthemum muticum, is a standout among Mountain Mints due to its large, showy, silver-tinged bracts that create a striking contrast with the small pinkish flowers. This perennial herb is native to the eastern United States and is well-known for its exceptional pollinator-attracting abilities, drawing in a wide range of bees, butterflies, and beneficial insects. Clustered Mountain Mint has a vigorous, spreading habit, making it a robust choice for naturalized areas, meadows, and pollinator gardens. It prefers moist, well-drained soils but is adaptable to a variety of conditions. Its aromatic leaves, which carry a strong minty scent, have been traditionally used for medicinal purposes, including digestive and respiratory relief.

Key Characteristics

• Showy Silver-Tinged Bracts
  Clustered Mountain Mint’s most distinguishing feature is its large, silvery bracts that surround small clusters of pinkish-white flowers. This makes it one of the more ornamental Mountain Mint species, providing visual interest throughout its long blooming period.

• Aggressive Spreader
  Of all the Mountain Mint species, Clustered Mountain Mint is one of the most aggressive spreaders. It forms dense colonies through its rhizomes, making it ideal for naturalized landscapes, erosion control, and meadow plantings, though it may require management in smaller gardens.

• Exceptional Pollinator Plant
  Like its relatives, Clustered Mountain Mint attracts a wide variety of pollinators, including bees, butterflies, and beneficial insects like parasitic wasps. Its long-lasting blooms provide critical nectar throughout summer, and its dense foliage offers shelter for insects.

• Medicinal Uses
  It is considered one of the most minty of the Mountain Mint species. Its leaves have a strong, minty aroma, more intense than many of its relatives like Slender Mountain Mint or Virginia Mountain Mint. This potent minty scent makes it particularly effective at repelling pests and also useful in herbal teas and remedies.
  

• Thrives in Moist Soils
  While many Mountain Mints are drought-tolerant, Clustered Mountain Mint thrives best in medium to moist, well-drained soils, making it a good choice for rain gardens, wet meadows, and streambank restoration projects.
