This British native species is an attractive and useful plant for covering the pond edge. Like other mints, it spreads by runners which creep over the top of the pot but these are not fast or invasive. It produces rounded leaves which have a pleasant minty scent when disturbed, and are a lovely purplish colour when grown in a sunny spot. In contrast to some of the other native pond plants which are up early in spring, Water Mint is fairly late up, and late to flower, making it useful for extending the growing season of the pond. Whorls of pretty lilac blooms on tall stems appear in late summer to autumn, which are attractive to bees (the plant is on the RHS 'Perfect For Pollinators' list). Cut off the foliage after the flowers have finished; the plant will sprout the following year from new runners at the base.
We recommend starting your Mentha aquatica off in a pot of 1 litre capacity. Read more on how to pot and care for your plant here.
