Marubium vulgare L.

Lamiaceae (Mint family)


An erect perennial in the Mint family, horehound grows to 2› feet tall. It is a native of Europe and considered invasive and generally unwanted. The stems are woolly white, have the characteristic four edges of the mint family and are somewhat woody at the base.

The leaves appear wrinkled, are coarsely toothed along the margins and are arranged in opposite pairs on the stem. Small, white flowers and bur-like fruits develop in clusters in the leaf axils. The clusters of fruits are a severe nuisance in sheep wool.

The plant has fair value for wildlife and poor for livestock.


Horehound is found along roadsides, dry waste areas and disturbed areas in most soil types across the state.
