Mentha x piperita citrata is a perennial found in areas such as Britain. A member of the Labiatae family, Mentha x piperita citrata (Ehrh.)Briq is also known by its common name of Eau De Cologne Mint. The perennial can grow to a height of 0.3 meters and up to 1 meters wide. The preferred habitat of A natural hybrid, M. aquatica x M. spicata found in moist soils on the sides of ditches, roadsides etc in S. England[5, 17]., with LMH soil and SN moisture levels. .

Eau De Cologne Mint is a zone 3 hardy plant that has medicinal uses - the medicinal usage rating of Eau De Cologne Mint is 2Eau de Cologne 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. The leaves and flowering plant are anodyne, antiseptic, antispasmodic, carminative, cholagogue, diaphoretic, refrigerant, stomachic, tonic, vasodilator[4, 9, 21, 165]. A tea made from the leaves has traditionally been used in the treatment of fevers, headaches, digestive disorders and various minor ailments[222]. The medicinal uses of this herb are more akin to lavender (Lavandula spp) than the mints. It is used to treat infertility, rapid heartbeat, nervous exhaustion etc[238]. 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].

Mentha x piperita citrata is 1 plant, whose flowers bloom typically in 8 - 10, and which is pollinated by Insects.

Known hazards of the plant: Although no specific mention has been seen for this sub-species, it should be noted that, in large quantities, the closely allied M. x piperita vulgaris can cause abortions, especially when used in the form of the extracted essential oil, so it should not be used by pregnant women.

The plant has an edibility rating of 3Leaves - raw or cooked. Used as a flavouring in salads or cooked foods[5]. A very pungent flavour, the leaves of the true eau-de-cologne mint are too aromatic for most tastes, though the cultivar 'Basil' has an excellent flavour and makes a very good substitute for basil in pesto[K]. A herb tea is made from the fresh or dried leaves[21, 183].

Cultivation tips: A very easily grown plant, it succeeds in most soils and situations so long as the soil is not too dry[1, 200]. Grows well in heavy clay soils. A sunny position is best for the production of essential oils, but . The plant also succeeds in partial shade. The plant prefers a slightly acid soil[16]. Plants are very tolerant of neglect, succeeding in long grass[K]. Hybridizes freely with other members of this genus. 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]. The flowers are very attractive to bees and butterflies[24]. A good companion for growing near cabbages and tomatoes, helping to keep them free of insect pests[14, 20]. The mint will need to be grown in containers to prevent it spreading too aggressively into the other plants. The whole plant has a strong minty aroma with a hint of ginger[245]. . The plant produces a better quality essential oil if . The plant is grown in dry ground[115]. Members of this genus are rarely if ever troubled by browsing deer[233].

. The plant should best be propagated by 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 3 centimeters 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.
