Species of flowering plant

Mentha aquatica (water mint; syn. Mentha hirsuta Huds.) is a perennial flowering plant in the mint family Lamiaceae. It grows in moist places and is native to much of Europe, northwest Africa and southwest Asia.

Water mint is a herbaceous rhizomatous perennial plant growing to tall. The stems are square in cross section, green or purple, and variably hairy to almost hairless. The rhizomes are wide spreading, fleshy, and bear fibrous roots. The leaves are ovate to ovate lanceolate, long and broad, green (sometimes purplish), opposite, toothed, and vary from hairy to nearly hairless. The flowers of the watermint are tiny, densely crowded, purple, tubular, pinkish to lilac in colour and form a terminal hemispherical inflorescence; flowering is from mid to late summer. Water mint is visited by many types of insects, and can be characterized by a generalized pollination syndrome, but can also spread by underground rhizomes. All parts of the plant have a distinctly minty smell. Unbranched, hairless plants, with narrower leaves and paler flowers, native to areas of Sweden and Finland near the Baltic Sea, have been called Mentha aquatica var. litoralis. Mentha aquatica is a polyploid, with 2n = 8x = 96 chromosomes.

Mentha aquatica was first described by Carl Linnaeus in 1753. As with other Mentha species, it was subsequently re described under a variety of different names; as of 2019, Plants of the World Online listed 87 synonyms, including four forms or varieties that it does not recognize. The cultivated eau de Cologne mint (also known as bergamot mint) is considered to be a variety of this species. It is a component of purple moor grass and rush pastures – a type of Biodiversity ActPlan habitat in the UK.

It can be used as an edible herb (like spearmint or peppermint) and to make a herbal tea. (not to be confused with bergamot essential oil).
