$10.00

Slender Mountain Mint is a native perennial wildflower in the mint family known for its fine, airy foliage and dense clusters of small white flowers. It is one of the more delicate-looking mountain mints but still extremely valuable for pollinators. All plants come in 1.5 quart pots.

Key facts:

  • Scientific name:Pycnanthemum tenuifolium

  • Family: Lamiaceae 

  • Height: Typically 2–3 feet (0.6–0.9 m) 

  • Bloom time: Mid to late summer 

  • Flower color: Small white flowers with subtle purple or pink speckling 

  • Habitat: Dry to medium-moist prairies, meadows, open woods, and roadsides 

  • Growing conditions: Full sun; tolerates dry, poor, and rocky soils very well 

Ecological importance:

  • Produces abundant nectar that attracts bees, butterflies, wasps, and other beneficial insects. 

  • Supports a wide diversity of pollinators during peak summer bloom. 

  • Helps maintain native insect populations in open habitats. 

Distinctive features:

  • Very narrow, almost thread-like leaves (hence “slender”). 

  • Upright, branching stems with a soft, wispy appearance. 

  • Dense clusters of tiny white flowers that can look like a light haze over the plant. 

  • Strong minty fragrance when leaves are crushed. 

Garden value:

  • Excellent for native meadows, pollinator gardens, and naturalistic plantings. 

  • More restrained spread than some other mountain mints, making it easier to manage. 

  • Drought tolerant and low maintenance once established. 

Summary:
Slender mountain mint is a fine-textured native wildflower that combines delicate, airy foliage with powerful pollinator appeal. Its adaptability to dry sites and strong ecological value make it a standout choice for native plant gardens in much of eastern North America.
