Slender Mountain Mint
Pycnanthemum tenuifolium

Also known as: Narrowleaf Mountain Mint
Penn State and Mt. Cuba pollinator trials repeatedly ranked this #1 for insect diversity and abundance. Cloud of tiny white flowers over fine needle-like foliage all summer. Spreads by rhizomes — give it room. Like other mountain mints, the leaves brew into a refreshing tea.
