Mountain Mint (Short-toothed)

Pycnanthemum muticum

Perennial flower

Silvery-green bracts flare around clusters of tiny pale-lavender flowers, making the whole plant look frosted from a distance. Xerces Society's darling — few native perennials support more diversity of beneficial insects per square foot.

Notes on growing

Spreads politely by rhizome, easy to divide. Aromatic foliage smells minty-thyme — brush it as you walk by. Not a true mint (Mentha), so it won't take over the garden.
