Pycnanthemum muticum (Blunt Mountain Mint)
A perennial wildflower native to the Eastern United States. Dense, white flower clusters with powdery, silver bracts bloom in summer and attract butterflies and bees. Mint-scented foliage is used in traditional medicine. Unlike true mints (Mentha spp.), mountain mint is not an aggressive spreader and will not take over your yard. Deer resistant.
Requirements: Full sun to partial shade and well-draining soil. Drought tolerant.
Height: to 3 ft. Spread: to 3 ft.
