MENTHA ARVENSIS / PUTHINA are aromatic, almost exclusively perennial herbs. They have wide-spreading underground and overground stolons[8] and erect, square,[9] branched stems. The leaves are arranged in opposite pairs, from oblong to lanceolate, often downy, and with a serrated margin. Leaf colors range from dark green and gray-green to purple, blue, and sometimes pale yellow.[6] The flowers are white to purple and produced in false whorls called verticillasters. The corolla is two-lipped with four subequal lobes, the upper lobe usually the largest. The fruit is a nutlet, containing one to four seeds.
