Saururus cernuus, commonly known as lizard's tail or water dragon, is a deciduous perennial plant native to wetlands and shallow water areas in eastern North America. Here are some key features and information about Saururus cernuus:

Habitat: Lizard's tail is typically found in wetlands, swamps, and along the edges of ponds and streams. It is well-adapted to growing in shallow water and is often partially submerged.

Appearance: The plant has distinctive, elongated flower spikes that resemble a lizard's tail, hence the common name. The flower spikes are usually white and grow in a cylindrical shape.

Leaves: The leaves are heart-shaped and have a distinctively textured surface. They are usually arranged alternately along the stems.

Flowers: The small, white flowers of Saururus cernuus are arranged in a spike that nods or hangs, giving the appearance of a lizard's tail. The flowering period typically occurs in late spring to early summer.

Fruit: The plant produces small, inconspicuous fruits after flowering. These fruits are not a prominent feature of the plant's ornamental value.

Size: Lizard's tail can reach a height of 1 to 3 feet (30 to 90 cm) and may spread to form dense colonies in suitable growing conditions.

Cultural Requirements: Saururus cernuus thrives in consistently moist to wet soils and is well-suited for planting in the margins of ponds, water gardens, or other areas with ample moisture. It can tolerate partial shade but can also grow in full sun.

Wildlife Attraction: The plant is known to attract butterflies and other pollinators. Its habitat in wetland areas also provides shelter and food for various aquatic and semi-aquatic species.
