About
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.
Where it grows
Water mint is native to much of Europe, northern Africa and western Asia. It has been introduced to North and South America, Australia and some Atlantic islands.
Uses
It can be used as an edible herb (like spearmint or peppermint) and to make a herbal tea. The cultivated variety known as eau de Cologne mint or bergamot mint is used to produce mentha citrata oil, also known as bergamot mint oil, an ingredient used in perfumery (not to be confused with bergamot essential oil).
