Lizard's Tail (//saururus cernuus//) usually grows in marshes and along the edges of streams and ponds. Above the water, the stem in hairy, and below there several stems that grow sideways and sprout new shoots. These stems are called rhizomes. The flowers are small and white. They grow in bunches called racemes along a narrow stem and hang over like a tail (hence, the name Lizard's Tail). The leaves are approximately 2 to 5 inches long. They are dark green and heart-shaped. The plant can grow up to 5 feet tall. However, most of it grows under the water. The roots under the water act as a shelter for many aquatic animals, such as turtles and frogs, which use the protected space to lay their eggs.

The plant is often seen growing in dense colonies, and many of the plants are growing from the same rhizomes underneath the water. It is a perennial plant that blooms from June to September.
