Pycnanthemum muticum
Short-toothed mountain mint
A clump-forming aromatic native perennial of eastern North America, grown as much for its silvery floral bracts as its bloom — the upper leaves below each flower head turn a frosted, dusty-mint color in summer. Dense flat-topped clusters of tiny two-lipped pinkish-white flowers cover the plant from mid to late summer and are a magnet for bees and butterflies. Unlike the true mints (Mentha), it spreads only modestly by rhizome and is not invasive.
