Mentha aquatica citrata
(Ehrh.) W.C.Werner
Lamiaceae
This hybrid species is sometimes treated as Mentha piperita citrata (Ehrh.) Briq., whilst at other times as a cultivated form Mentha aquatica 'Citrata'
Mentha × piperita citrata (Ehrh.) Briq.
Mentha citrata Ehrh.
Common Name: Eau De Cologne Mint
General Information
Mentha aquatica citrata is a perennial plant that can grow up to 0.30 metres tall.
It is harvested from the wild for local use as a food, medicine and source of materials.
The plant is cultivated on a commercial scale in some countries, and is often planted in home-gardens, especially in Europe, Mexico, Guatemala and Cuba, as an aromatic plant or for the preparation of herbal tea[
].
Known Hazards
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.

Mentha species are very prone to hybridisation and so the seed cannot be relied on to breed true. Even without hybridisation, seedlings will often 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[

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[

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.
