Pycnanthemum muticum

Mountain Mint-Short Toothed

This popular wildflower is one of the very best for pollinators, supporting a diverse group of native bees and butterflies. It is showiest in late summer when the entire plant appears to be covered in silver dust due to the showy bracts. Its dark green, mint-scented foliage spreads slowly by rhizomes but is easily controlled. Tolerates clay soil, heat and mild drought.
