It succeeds grow best under cool conditions, most soils, humid localities and situations so long as the soil is not too dry. It tolerates much drier conditions than other members of the genus. Prefers a slightly acid soil, in heavy clay soils. Mints grow best in deep soils rich in humus, with a pH of 6-7.5. A sunny position is best for production of essential oils, its also grows in partial shade.
- Stem – prostrate, stoloniferous, pubescent with appressed hairs, cylindrical, much-branched, and ultimate ascending terminal branches.
- Leaves – elliptic to oblong-ovate, lanceolate to broadly lanceolate, 1.5 to 4 centimeters long, acute at apex, short-stalked with toothed margins, and rounded or blunt tipped, membranaceous, stipules absent, strongly aromatic herb.
- Flowers – bisexual, hairy and purplish to bluish, borne in axillary head-like whorls. Corolla funnel-shape and hairy, Calyx tubular-campanulate and pressed hairy.
- Fruit – nutlets ellipsoid, finely granular, about 1 mm long, often pointed at apex.
- Generative propagation is by seed. Without hybridisation, seedlings will not be uniform and so the content of medicinal oils will vary.
- Vegetative propagation is by division, can be easily carried out at almost any time of the year. Virtually any part of the root is capable of growing into a new plant. For maximum increase it is possible to divide the roots up into sections no more than 3 cm long.
