Lizard's Tail

Saururus cernuus

The Story

Plant Bio

Saururus cernuus, lizard's tail, is a spreading aquatic perennial native to eastern North America, growing one to four feet tall in shallow water and saturated ground. Bright green heart-shaped leaves are carried on arching stems, and in early summer slender white flower spikes emerge opposite a leaf, nodding over at the tip. The flowers are fragrant, which is unusual among marginal aquatics.

The drooping, tapering flower spike is what gives it its name, and it is the easiest way to identify the plant at a glance. It colonises quickly by rhizome in mud or standing water, forming dense stands that shelter wood ducks and other wetland wildlife, so it wants a pond margin rather than a mixed border.

Uses & Benefits:

Ornamental UsesFragrant nodding white spikes over bright heart-shaped foliage at the water's edge.
Practical UsesColonises shallow margins fast, binding mud and softening hard pond edges.
Ecological BenefitsDense stands provide cover for wood ducks and other wetland wildlife.

Planting

How to Grow

  1. Plant in spring in mud or shallow standing water.
  2. Choose full sun to partial shade.
  3. Set crowns just below the water surface or in saturated soil.
  4. Keep permanently wet; it will not tolerate drying out.
  5. Contain it in a basket if you need to limit its spread.
  6. Cut spent stems back in late winter.

Pro Tip

Plant it in a submerged basket rather than open mud unless you want a colony — it runs fast once its roots are in warm wet ground.
