Mentha aquatica (Water Mint)
Water Mint, Fish Mint
Highly aromatic, Mentha aquatica (Water Mint) is a vigorous herbaceous perennial with purple stems bearing crossed pairs of ovate, dark green leaves, 1-2 in. long (2-5 cm), with serrated margins. Often tinged with purple, the foliage is fragrant when crushed and can be used in cooking or for making tea. In mid to late summer, tiny pinkish-purple flowers are produced in rounded terminal spikes. Rich with a minty aroma, they are pollinated by insects and are attractive to butterflies. Native to Eurasia, Water Mint occurs in the shallow margins and channels of streams, rivers, pools, dykes, ditches, canals, wet meadows, marshes, and fens.
