Alisma Plantago-Aquatica, also known as European water-plantain, common water-plantain or mad-dog weed, is a perennial flowering aquatic plant widespread across most of Europe and Asia from Portugal and Morocco to Japan, Kamchatka and Vietnam. It is also regarded as native in northern and central Africa as far south as Tanzania. It is reportedly naturalised in southern Africa, Australia, New Zealand, Alaska, British Columbia, Washington State and Connecticut. Some sources maintain that the species is widespread across North America, but these reports appear to have been based on misidentified specimens. It is found on mud or in fresh waters.

Alisma plantago-aquatica is a hairless plant that grows in shallow water, consists of a fibrous root, several basal long stemmed leaves 15–30cm long, and a triangular stem up to 1 m tall. It has branched inflorescence bearing numerous small flowers, 1cm across, with three round or slightly jagged, white or pale purple petals. The flowers open in the afternoon. There are 3 blunt green sepals, and 6 stamens per flower. The carpels often exist as a flat single whorl. It flowers from June until August.

The word alisma is said to be a word of Celtic origin meaning "water", a reference to the habitat in which it grows. Early botanists named it after the Plantago because of the similarity of their leaves. Narrow leaved water plantain Alisma lanceolatum differs only in that the leaf tips are acuminate and shape is narrow lanceolate. According to Flora of the U.S.S.R. (1934, translated 1968), “A powder prepared from dried roots is used in popular medicine as a cure for rabies and crushed leaves are used against mammary congestion; fresh leaves are employed in homeopathy. [...] Since this species is often confounded or identified with others of the genus, the reported data may also refer to [Alisma orientale or Alisma lanceolatum].” Indeed, Alisma plantago-aquatica is also known as mad-dog weed, as if it could be used to cure rabies. Do not confuse this with Scutellaria lateriflora (mad-dog skullcap), which is also sometimes called mad-dog weed.

Alisma plantago-aquatica grows readily from seed and can be grown at any time.

Water Plantain -alisma plantago-aquaticagrows only in very wet soil at the edges of streams, ponds, and lakes. Plants can be grown in sun or shade and are ideal for a garden pond edge or bog garden where they will attract a wide range of insect life such as bees, dragonflies and damselflies. Water Plantain typically grow to about 2 foot high or more and produces tiny white flowers from June to September. It looks best growing amongst other wetland plants with similar flowering times for example Common Fleabane, Purple loosestrife, Hemp agrimony, Gypsywort and Water Mint. 

How to grow Water Plantain Seeds
Water Plantain seeds should be sown thinly in spring or autumn, either outside, where they are to flower, or in seed trays and covered lightly with compost. The soil or compost should not be allowed to dry out. Seedlings can be pricked out and grown on, for planting out later in the year. Once established Water Plantain will self seed readily”.
