Water Mint

Mentha aquatica

As the name suggests, Water Mint occurs in the shallow margins and channels of streams, rivers, boggy areas, ditches, canals, wet meadows, and marshes . If the plant grows in the water itself, it rises above the surface of the water.Plants can grow in water up to 15cm deep.  It is not neccessary to plant into water however, as it will grow very well in soil.

Water Mint is pollinated by insects, and also spreads by underground rhizomes, like other species of mint. All parts of the plant have a distinctly minty smell.

Succeeds in most soils and situations so long as the soil is not too dry. Grows well in heavy clay soils (high moisture content). A sunny position is best for production of essential oils, but it also 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. Hybridizes freely with other members of this genus. The whole plant, especially when bruised, has a pungent aroma of bergamot. The flowers are especially attractive to bees and butterflies like many in the Mentha genus. A good companion for brassicas, as it is said to repel pest insects. Leaves  can be eaten  raw or cooked and have a strong distinctive peppermint-like fragrance. Used as a flavouring in salads or cooked foods. Some people find this variety too strong to eat.  A herb tea can made from the leaves and can help relieve the symptoms of colds and flu.The plant has repellent qualities and is said to deter flies, mice and rats. It has a pleasant, fresh scent and was formerly used as a strewing herb and has been strewn in granaries to keep mice and rats off the grain.
