Water mint. A native European mint, a vigorous spreading perennial growing 60 cm (2 ft) high. The leaves (and the oil extracted from them) have a good minty flavour and are used as kitchen herbs. An excellent bee and butterfly plant. When growing in or near flowing water it purifies the water, so is a good plant to used in reed bed sewage systems. Likes a moist or wet site in sun or part shade; hardy to -20°C.
