Short-toothed Mountain Mint

Pycnanthemum muticum

Silvery bracts crown flat clusters of tiny white flowers from midsummer into fall, over minty foliage on square stems. The standout pollinator magnet of the Penn State trials, drawing more insect visits and more species than almost anything else tested. Rhizomatous but far better behaved than common mountain mint.
