Description

Wild mint is a herbaceous perennial plant generally growing to 10–50 cm. It has a creeping rootstock from which grow erect or semi-sprawling squarish stems. The leaves are in opposite pairs, simple, 2–6.5 cm long and 1–2 cm broad, hairy, and with a coarsely serrated margin. The flowers are pale purple (occasionally white or pink), in whorls on the stem at the bases of the leaves. Each flower is 3 to 4 mm long and has a five-lobed hairy calyx, a four-lobed corolla with the uppermost lobe larger than the others and four stamens. The fruit is a two-chambered carpel.
