Pycnanthemum incanum, commonly known as hoary mountainmint, is a perennial herbaceous plant in the Lamiaceae family. It is native to the eastern United States, where it is typically found in dry, open woodlands, fields, and along roadsides.

Description

Pycnanthemum incanum grows to a height of 1 to 3 feet (30 to 90 cm). The plant has square stems, which is characteristic of the Lamiaceae family. The leaves are opposite, lanceolate to ovate, and have a distinctive hoary (grayish-white) appearance due to the presence of fine hairs. The leaves are aromatic when crushed, emitting a minty fragrance.

The flowers of Pycnanthemum incanum are small, tubular, and white to pale lavender in color. They are arranged in dense, terminal clusters. The blooming period extends from mid-summer to early fall. The flowers are highly attractive to a variety of pollinators, including bees, butterflies, and other insects.
