Pycnanthemum loomisii, commonly known as Loomis’ Mountainmint, is a deciduous perennial herb native to wet meadows and stream banks in the Southeastern United States. It typically grows to a height of 3-5 feet (0.9-1.5 meters) and a width of 3-4 feet (0.9-1.2 meters). This plant features narrow, lance-shaped leaves and dense clusters of small, tubular pink and white flowers that bloom in the summer and are highly attractive to pollinators such as bees and butterflies.

Loomis’ Mountainmint is valued for its aromatic foliage and flowers, which can be used for culinary purposes or to make herbal teas. It is often used in naturalized plantings, pollinator gardens, and as a border plant. It thrives in full sun to part shade and prefers moist, well-drained soils. While it is drought-tolerant once established, it benefits from regular watering during prolonged dry spells. It is not known to have significant disease or pest problems, but care should be taken to avoid overly wet conditions, which can lead to root rot.CC BY-SA 4.0
