Lizard’s tail is a perennial plant that grows up to 3’ tall, branching occasionally native in most of Illinois but largely absent from the driftless NW section of the state.

Habitats include soggy ��һ�Թ�openings in floodplain and bottomland woodlands, shallow vernal pools in wooded areas, swamps, seeps and springs in semi-shaded areas, shallow slow-moving streams, and ditches along wooded areas. Lizard's Tail is usually found in higher quality wetland habitats where there is some shade. It thrives along many reaches of the Chicago River system including in the North Shore Channel where a Friends’ partnership with the Illinois Department of Natural Resources established new colonies. This effort continues with the Shedd Aquarium.

The leaves of Lizard’s Tail are heart shaped, 3-6’ long on opposite branches. The flowers of Lizard’s Tail are a defining feature of the plant, as they form a 4-7’ long semi-cylindrical shaped spike of dense whorls of tiny fragrant white flowers. They typically bloom June to September in the Chicago region. The flowers then give way to small green fruits.

The genus name comes from the Greek words sauros meaning lizard and oura meaning tail.
