Pycnanthemum muticum (Mountain Mint) QT

Beloved by bees and butterflies, clustered mountain mint blooms from midsummer into autumn, with eye-catching silver bracts surrounding bunches of tiny tubular flowers in a very light pink. These unique flowers sit atop upright stems that reach two to three feet tall. Deer- and rabbit-resistant, mint-scented leaves line the stems, which rise from rhizomes that spread through the soil to create a dense ground cover. 2025 Perennial Plant of the Year.
