Toxicity unknown
Lizard's-tail (Saururus cernuus) is not listed by the ASPCA Animal Poison Control Center (opens in new tab) or the other sources we check, so we have no verdict for it either way.

Lizard's-tail is a native perennial that thrives in moist, shady conditions with distinctive white, curved flower spikes that bloom through summer. This clumping plant produces heart-shaped leaves and works well in rain gardens or consistently wet areas where many other plants struggle.
Growing Lizard's-tail
Grow Lizard's-tail in part shade and high water. Mature plants reach 12 to 36 inches tall and spread 12 to 24 inches wide. Expect low maintenance to keep it looking intentional in a front yard.

Care guidance last updated: August 2026
Cross Timbers (includes Fort Worth, TX)
Year-round
Lizard's tail is a spreading, moisture-loving perennial that works well in a wet, shaded corner of a Fort Worth yard even though it is not confirmed native to this exact area.
- This plant needs soil that stays wet to muddy all the time, not just regular garden watering, so it belongs at a pond edge, in a rain garden low spot, or in a bog planter rather than a regular flower bed.
- Its confirmed Texas range centers on the Blackland Prairie and Gulf Coast wetlands to the east and south, not the Fort Worth Prairie itself, according to the Lady Bird Johnson Wildflower Center, so treat it here as a well-adapted wetland plant rather than a local native.
- Part shade to full shade works best. It can take more sun if the roots never dry out, but Fort Worth summer sun on drying soil will scorch the leaves.
- It spreads by underground rhizomes and slowly fills a wet area, so give it a contained spot or plan to thin it every year or two.
- It is winter hardy well beyond what Fort Worth sees in a normal cold snap, so the roots come back reliably each spring.
Fall
Fall is when the foliage starts to die back and a light cleanup keeps the planting looking tidy before frost.
- Growth slows as days shorten, and leaves begin to yellow ahead of Fort Worth's average first freeze around November 22, per the National Weather Service.
- Cutting back dead and yellowing stems in late fall keeps a front-yard water feature or bog bed looking neat through winter.
- Keep the soil from drying out completely even as watering needs drop, since the rhizomes are still active below the surface.
- This is a fine time to divide or relocate a spreading colony before winter dormancy sets in.
Cutting back the dead foliage in late fall keeps a visible water feature or bog bed tidy for the street view through winter.
Winter
Lizard's tail goes fully dormant in winter and the rhizomes handle typical Fort Worth cold without any special protection.
- The above-ground growth dies back completely after frost. This is normal, the plant is resting below the soil or waterline, not dead.
- Its hardiness range covers much colder winters than Fort Worth typically sees, so a normal cold snap will not kill the roots.
- Container plantings above ground are the exception. Move an above-ground pot to a sheltered spot or sink it into the ground so the root ball does not freeze solid during a hard freeze.
- No fertilizing or heavy watering is needed while it is dormant. Just keep the area from drying out completely.
A bare, cut-back bog bed over winter is expected and temporary, not something a neighbor or HOA would flag as neglect.
Spring
Spring is when lizard's tail wakes up and needs steady moisture as new shoots push through the mud.
- New leaf shoots usually appear once the soil warms after Fort Worth's average last freeze around March 12, per the National Weather Service.
- Keep the root zone wet through spring dry spells. Fort Worth's heavy clay holds water well, but a dry week can still stress new growth.
- If the colony is crowded from last year, spring before new growth is a good time to dig and divide clumps.
- White flower spikes typically begin by late spring and continue into summer.
Summer
Summer heat means lizard's tail needs consistent water and a break from full afternoon sun.
- Fort Worth summer afternoons regularly hit the upper 90s to 100s, so give this plant part shade if it is not sitting in standing water, to keep the leaves from scorching.
- Check pond edges, rain gardens, or bog containers often since heat speeds up evaporation and the soil must not dry out.
- White flower spikes keep blooming through summer. Snipping off spent spikes can encourage a second round of blooms.
- This is the season the rhizomes spread fastest, so thin the colony if it is crowding neighboring plants.

Texas Blackland Prairies (includes Dallas, TX)
Year-round
Lizard's tail is a spreading, moisture-loving perennial that fits naturally into wet, shaded corners of a Dallas yard.
- This plant needs soil that stays wet to muddy all the time, not just regular garden watering, so it belongs at a pond edge, in a rain garden low spot, or in a bog planter rather than a regular flower bed.
- It grows naturally in the Blackland Prairie region that runs through the Dallas area, in wet ditches and stream edges, according to the Lady Bird Johnson Wildflower Center.
- Part shade to full shade works best. It can take more sun if the roots never dry out, but Dallas summer sun on drying soil will scorch the leaves.
- It spreads by underground rhizomes and will slowly fill a wet area, so give it its own contained spot or plan to thin it every year or two.

In an HOA neighborhood
Lizard's-tail takes more care to keep looking intentional in a front yard. Maintenance level: low. Consider it for backyard or mid-zone beds rather than the street edge.
Works well in: backyard only.
- Requires consistently wet soil that's unusual in typical landscaping
- Informal wetland appearance may look out of place in manicured settings
- Can spread aggressively in ideal conditions
Wildlife value
The summer flowers attract native bees and beetles with their accessible nectar and pollen. The plant also provides habitat for moisture-loving insects in its preferred wetland settings.
