The Common Water-plantain (Alisma plantago-aquatica), also known as Mad-dog weed, is a perennial flowering plant native to most of the Northern Hemisphere, in Europe, northern Asia, and North America. It is found on mud or in fresh waters.
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.
It is a hairless plant that grows in shallow water, consists of a fibrous root, several basal long stemmed leaves 15-30 cm 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 whorle. It flowers from June until August.
