Pycnanthemum verticillatum, commonly known as Whorled Mountainmint, is a deciduous perennial herb native to the open woodlands, grasslands, and along stream banks in the Eastern and Central United States. It typically grows to a height of 3-5 feet (0.9-1.5 meters) and a width of 1 foot (0.3 meters). The plant features a square stem and whorled leaves, which are highly aromatic when crushed. From mid to late summer, it produces dense clusters of small, tubular, two-lipped purple and white flowers that are highly attractive to pollinators.

Whorled Mountainmint is valued for its fragrant foliage and flowers, which are used in herbal teas and as a culinary herb. It is also appreciated for its ability to attract bees, butterflies, and other beneficial insects, making it a suitable choice for pollinator gardens. In cultivation, it is often used in borders, native plant gardens, and as part of naturalized areas. Whorled Mountainmint thrives in full sun to part shade and prefers medium to dry soils with good drainage. It is drought-tolerant once established and requires minimal maintenance. While generally disease-free, it can spread aggressively by rhizomes, so gardeners may need to manage its spread to prevent it from becoming invasive in a garden setting.CC BY-SA 4.0
