Cultivation Details

We do not have much information on this species but it has been seen growing in a number of gardens in Britain and would seem to be quite hardy. The following notes are based on the general needs of the genus. Succeeds in most soils and situations so long as the soil is not too dry[1, 16, 200]. Prefers a slightly acid soil[16]. Grows well in heavy clay soils. A sunny position is best for production of essential oils, but succeeds in partial shade. Most mints have fairly aggressive spreading roots and, unless you have the space to let them roam, they need to be restrained by some means such as planting them in containers that are buried in the soil[K]. Hybridizes freely with other members of this genus. The whole plant has a minty aroma. The flowers are very attractive to bees and butterflies[24]. A good companion plant for growing near cabbages and tomatoes, helping to deter insect pests. Members of this genus are rarely if ever troubled by browsing deer[233].

Medicinal Uses*

Medicinal Rating: 2/5
Asian mint, like many other members of this genus, is often used as a domestic herbal remedy, being valued especially for its antiseptic properties and its beneficial effect on the digestion. Like other members of the genus, it is best not used by pregnant women because large doses can cause an abortion. A tea made from the leaves of most mint species has traditionally been used in the treatment of fevers, headaches, digestive disorders and various minor ailments[222]. The leaves are harvested as the plant comes into flower and can be dried for later use[238]. The essential oil in the leaves is antiseptic, though it is toxic in large doses[222].

• Antiseptic - Preventing sepsis, decay or putrefaction, it destroys or arrests the growth of micro-organisms.
• Carminative - Reduces flatulence and expels gas from the intestines.
• Febrifuge - Reduces fevers.

Propagation

Seed - sow spring in a cold frame. Germination is usually fairly quick. Prick out the seedlings into individual pots when they are large enough to handle and plant them out in the summer. Mentha species are very prone to hybridisation and so the seed cannot be relied on to breed true. Even without hybridisation, seedlings will not be uniform and so the content of medicinal oils etc will vary. When growing plants with a particular aroma it is best to propagate them by division[K]. Division can be easily carried out at almost any time of the year, though it is probably best done in the spring or autumn to allow the plant to establish more quickly. Virtually any part of the root is capable of growing into a new plant. Larger divisions can be planted out direct into their permanent positions. However, for maximum increase it is possible to divide the roots up into sections no more than 3cm long and pot these up in light shade in a cold frame. They will quickly become established and can be planted out in the summer.

Known Hazards

Although no records of toxicity have been seen for this species, large quantities of some members of this genus, especially when taken in the form of the extracted essential oil, can cause abortions so some caution is advised.

Other Uses

An essential oil is obtained from the whole plant. Rats and mice intensely dislike the smell of mint. The plant was therefore used in homes as a strewing herb and has also been spread in granaries to keep the rodents off the grain[244].

• Essential - Essential oils that are used in perfumery, medicines, paint solvents, insect repellents etc.
• Repellent - Plants that are said to deter but not necessarily kill various mammals, birds, insects etc.
• Strewing - Plants, usually aromatic, that are strewn on the floor to give a nice smell, repel insects etc.
