White horehound is a grey-leaved, downy perennial herb in the mint family, 25 to 45 cm tall, with white flower clusters on the upper stems. It thrives in hot, dry, sunny spots with lean soil and is grown mostly as a medicinal and culinary herb.
Marrubium vulgare (white horehound or common horehound) is a flowering plant in the mint family (Lamiaceae), native to Europe, northern Africa, and southwestern and central Asia. Specifically, it emerged in the region between the Mediterranean Sea and Central Asia and now inhabits all continents save Antarctica. It is also widely naturalized in many places, including most of North and South America.
It is a grey-leaved herbaceous perennial plant, and grows to 25–45 centimetres (10–18 in) tall. The leaves are 2–5 cm (0.8–2.0 in) long with a densely crinkled surface, and are covered in downy hairs. The flowers are white, borne in clusters on the upper part of the main stem.
