Mentha arvensis L.

English Name : Mint; Japanese Mint, Peppermint

Family : Lamiaceae

Origin : Europe to Indo-Malaysia

It is a branched, downy herb. From the low, spreading, quadrangular stems that lie near the ground, the flowering stems are each year thrown up, 6 to 12 inches high. The leaves, springing from the stems, in pairs, are stalked, their outlines freely toothed. The upper leaves are smaller than the lower, and the flowers are arranged in rings (whorls) in their axils. The flowers themselves are small individually, but the delicacy of their colour and the dense clusters in which they grow, give an importance collectively, as ring after ring of the blossoms form as a whole a conspicuous head.

Occasional by roadsides and on cultivated ground.

Parts Used : Flower and leaf
