Saururus cernuus (Lizards tail) - Marginal Pond Plants - MP105

Saururus cernuus, commonly known as Lizard's Tail, is a perennial aquatic plant native to North America. It is often found growing in wetland areas, along pond edges, and in shallow, slow-moving streams. Lizard's Tail is admired for its attractive white flowers, striking foliage, and unique growth habit, making it an excellent addition to water gardens, bog gardens, and natural wetland landscapes.

Description

Saururus cernuus typically grows to a height of 60–90 cm (24–36 inches), with erect stems that bear large, heart-shaped leaves. The leaves are glossy green and have a distinct pointed tip, resembling a lizard's tail, which gives the plant its common name. The leaves are arranged alternately along the stems and provide a lush, tropical look to water features.

In late spring to early summer (typically from May to July), Lizard's Tail produces a distinctive, long, and slender inflorescence that resembles a tail, hence the name. The flowers are small and white, arranged in dense, spike-like clusters along the stem. The plant's flowers are not highly showy but are fragrant, attracting pollinators such as bees and butterflies. The unique flower structure and long, trailing nature of the inflorescences create an eye-catching effect in the garden.

Growing Conditions

Saururus cernuus thrives in full sun to partial shade and prefers consistently moist or wet soil. It is ideal for planting along the edges of ponds, in shallow water up to 30 cm (12 inches) deep, or in bog gardens with nutrient-rich soil. The plant does well in slightly acidic to neutral pH soils and can tolerate a variety of soil types, including clay, loam, or sandy soils.

The plant performs best in consistently moist environments but can also tolerate short periods of drought once established. It is hardy in the UK and can survive frost, reemerging in the spring after the winter dormancy period.

Propagation and Care

Saururus cernuus can be propagated by division, which is typically done in early spring or autumn. The plant spreads by rhizomes, and division allows gardeners to control its spread while encouraging fresh growth. The rhizomes can be divided into smaller sections and replanted in moist or submerged conditions.

Once established, Lizard's Tail is relatively low-maintenance. It requires regular watering and should be grown in consistently moist soil or shallow water. The plant benefits from occasional thinning to prevent overcrowding and maintain its shape. Deadheading spent flowers and trimming damaged or yellowing leaves will help keep the plant looking tidy.

Uses

Saururus cernuus is primarily used for ornamental purposes in water gardens, pond edges, and wetland landscapes. Its unique, lizard-tail-like flower spikes and heart-shaped leaves add texture and vertical interest to aquatic settings. It works well in naturalized plantings, where it can blend with other water-loving plants or be used as a specimen plant in a feature.

The plant is also used in wetland restoration and in areas where soil stabilization is needed. Its dense root system helps prevent erosion along water margins, making it a great plant for creating naturalistic water features that need to be protected from soil loss.

Ecological Value

Lizard's Tail offers several ecological benefits. Its dense foliage provides shelter for small aquatic creatures, insects, and amphibians, contributing to the overall biodiversity of wetland areas. The plant’s flowers attract pollinators, such as bees and butterflies, supporting the local ecosystem. Additionally, its dense root system helps stabilize soil, preventing erosion along water margins and improving the overall health of aquatic ecosystems.

The plant also plays a role in improving water quality by filtering excess nutrients and reducing algae growth, which can enhance the health of ponds and streams.

Considerations

While Saururus cernuus is a low-maintenance and hardy plant, it can spread rapidly by rhizomes, so it may need to be controlled in smaller garden spaces. It is best planted in an area where it has room to grow or in containers to prevent it from overtaking other plants. Regular division helps manage its growth and maintain a healthy, compact plant.

With its distinctive lizard-tail-like flower spikes, heart-shaped leaves, and ecological benefits, Saururus cernuus is an excellent choice for water gardens, ponds, and wetland landscapes. Its ability to thrive in wet conditions, provide shelter for wildlife, and improve water quality makes it a valuable plant for any aquatic garden setting.
