Pycnanthemum incanum is native to Eastern United States and into Ontario, Canada. It prefers to grow on rocky, gravelly or sandy soil, and typically grows in woods, thickets, fields, and hills.

Pycnanthemum incanum is an erect, many-branched perennial plant. It grows to 2 to 4 feet (0.6 to 1.2 m) high by 4 feet (1.2 m) wide. The stems are covered with a soft, whitish down. A vigorous and often aggressive grower, this plant spreads by long rhizomes. The plant is called Hoary mountain-mint because of the hoary/white appearance of the upper leaves and bracts beneath its flower clusters. White blooms appear from July to September.

The species is hermaphrodite (has both male and female organs) and is pollinated by Insects. Pycnanthemum means “dense flower-clusters” in Greek, and the flowers are favored by butterflies, moths, honeybees, and some species of wasps.


Cultivation: Succeeds in most soils but prefers a rich loamy soil in full sun or partial shade with plenty of moisture in the growing season.

Edible Uses: The fresh or dried leaves are brewed into an aromatic mint-like tea.
