Mountain mint is a NC native perennial in the mint family found primarily in the coastal and Piedmont areas of the state. The fragrant leaves and flowers attract pollinators including bees, butterflies and wasps. It is resistant to browsing by rabbits and deer. In late summer it is topped by rounded clusters of white to lavender tubular flowers.
Mountain Mint prefers rich loamy moist soil with good drainage in full sun to partial shade. It will tolerate drier conditions once established. Use in the pollinator/native garden, naturalized areas, meadows, or along ponds or streams.
