Lizard’s Tail (Saururus cernuus): Plant Description & Features
Product Description
Saururus cernuus (Lizard’s Tail) is a distinctive emergent wetland perennial prized for its heart-shaped leaves and gracefully arching white flower spikes that curve like a lizard’s tail from late spring into summer. The blooms are fragrant, drawing pollinators, and the dense rhizomatous clumps provide excellent shoreline cover and water-edge texture. Built for saturated soils and shallow water, Lizard’s Tail thrives on pond shelves, in rain-garden basins, and along slow-moving streams—delivering filtration, erosion control, and season-long ornamental value with minimal care.

Care & Growing Information
- Site & Light: Prefers part shade; tolerates full sun with consistent water. In deep shade, flowering is reduced.
- Water Depth: Set crowns at or just below the water surface; maintain 0–4″ of water above crowns on pond shelves. In rain gardens, site in zones that remain saturated after storms.
- Soil: Use organic-rich, heavy loam/muck; in lined ponds, plant in aquatic containers with loam (not potting mix) and top with gravel.
- Planting: Space 18–24″ for quick cover. Water newly installed plants until established if soils fluctuate.
- Maintenance: Low-care. Thin or edge expanding rhizomes to control spread; deadhead spent spikes if self-sowing is not desired; remove old foliage in late winter/early spring.
- Design Tips: Mass along shorelines for a lush, natural edge. Combines well with pickerelweed, soft rush, irises, and native sedges for layered wetland structure.
Key Features
- Showy, fragrant white “tail” blooms late spring–summer
- Native emergent that stabilizes banks and filters water
- Thrives in saturated soils and shallow standing water
- Dense cover for wildlife habitat; deer resistant
- Spreads to form naturalized colonies—easy to manage with edging
Problems
- Few significant issues. Can spread assertively in ideal conditions—use containers or edging where containment is needed. In low moisture or high heat without water, foliage can scorch—maintain saturation.
Uses in the Landscape
- Pond shelves and shorelines for color, cover, and filtration
- Rain-garden basins and bioswales with periodic standing water
- Constructed wetlands and stormwater features for stabilization
- Aquatic containers for naturalistic accents on patios/decks
Availability / Ordering
- Sizes Offered: #1 Gallon, 4″, DP-50 Plug
- Recommended Spacing: 18–24″ for cohesive drifts and quick bank coverage.
Why You’ll Love It
- Distinctive arching white blooms with gentle fragrance
