Water plantain (Alisma plantago-aquatica) is a perennial plant belonging to the Alismaceae family. This flowering plant is found growing naturally in regions ranging from Portugal and Morocco to Japan, Vietnam and Kamchatka in Asia. It is believed that this aquatic species has its origin in the northern and central regions of Africa, extending northwards up to Tanzania. Generally this species is found in fresh waters or on mud. According to reports, over the years this plant has been naturalized in various regions, including Australia, New Zealand, Africa, British Columbia and Alaska. However, it appears that these reports are based on specimens that have not been identified correctly.
A hairless plant found growing in shallow water, Alisma plantago-aquatica comprises a fiber-like root, many long-stemmed leaves at the base (each leaf measuring anything between 15 cm and 30 cm in length) and a 1-meter-long triangular stem. This plant produces branched inflorescence comprising several small blooms. Each flower of water plantain has three rounded or serrated, white or pale purple hued petals and measure roughly 1 cm in diameter. Interestingly, these flowers open only in the afternoon. Each water plantain flower has three blunt green-hued sepals and six stamens. The carpels of this flower generally occur in the form of a flat solitary whorl. The flowers of water plantain are hermaphrodite in nature having both male as well as female reproductive organs. Usually, flies pollinate these flowers.
The term alisma is believed to have its origin in Celtic and this word denotes “water”, having reference to the plant’s natural habitat. In the initial days, botanists named this species after Plantago owing to the comparison of its leaves.

Habitat and cultivation
As the name of the plant suggests, water plantain is found growing in boggy grounds, on the periphery of shallow ponds, damp ditches as well as the edges of similar water bodies. This herb blooms during the period between June and August, while the seeds become mature from July to September.
Water plantain thrives well when grown in sunlit position in swampy ground or shallow water bodies having a maximum depth of 25 cm. These plants have the ability to self-sow very aggressively, provided they are grown in suitable locations. Water plantain attracts many slugs.
Water plantain is generally propagated by its seeds, which are ideally sown in cold frames immediately after they become ripe. In order to keep the soil in the pot wet, you should always position the pots in water having a depth of roughly 3 cm. When the seedlings have grown large enough so that they can be handled properly, you need to keep growing them in a cold frame, at least for the first winter for their existence. The young water plantains can be planted outdoors towards the end of spring.
Water plantain can also be propagated by means of root division, ideally undertaken in spring or autumn. Propagating the plant via division is rather simple. You can plant the divisions directly in their permanent positions outdoors.
Side effects and cautions
Water plantain should be used with caution, as the fresh leaves as well as the roots of the plant are somewhat toxic. However, when you dry or heat the plant, its toxic compounds are destroyed.
