Houttuynia cordata

OrnamentalPet-Friendly

Houttuynia cordata is a colorful and vigorous herbaceous perennial, loved for its striking foliage and wetland tolerance. With heart-shaped, aromatic leaves and bright red stems, this plant adds bold contrast to pond edges and shady borders. Often called Chameleon Plant, it thrives in moist soil or shallow water and spreads quickly by underground rhizomes.

Care Instructions:

This fast-spreading plant forms dense mats of foliage with bright, metallic-blue-green leaves that may flush with red. Upright stems bear small white flower spikes in summer, each with four showy white bracts. Popular varieties like ‘Variegata’ boast dramatic multicolored leaves, while ‘Plena’ produces rare double blooms. Though beautiful, it can be invasive in ideal conditions.

Light

Prefers partial shade or dappled light. Too much sun can scorch the leaves, especially variegated types. In cooler areas, it tolerates full sun if soil stays moist.

Water

Needs consistently moist soil or shallow water (2.5–5 cm deep). Ideal for bog gardens and pond margins. Never let the soil dry out; standing water is tolerated.

Soil

Rich, loamy, or clay soil holds moisture well. It adapts to ordinary garden soil if kept damp. Plant rhizomes horizontally 7.5 cm deep, or container-grown plants at pot depth.

Temperature

Hardy down to at least –15 °C (5 °F). Dies back in winter and regrows from underground rhizomes in spring.

Humidity

Thrives in high humidity. Natural bog or water-edge conditions provide the ideal environment. Protect from dry winds or drying out.

Fertilizer

Not heavy feeders. Add organic compost or a general-purpose fertilizer in spring to support growth and coloration in variegated types.

Best Placement Ideas

  • Margins of small ponds or water features
  • Shady bog gardens or moist woodland edges
  • Containers with submerged trays
  • Underplanting for taller marginal plants

Common Issues

  • Invasive spreading via rhizomes
  • Leaf scorch in strong sun
  • Loss of variegation in low light
  • Weak color if planted in nutrient-poor soil

Things to Watch Out For

  • Use barriers or containers to control spread
  • Strong scent when leaves are bruised
  • Prune back in spring to manage vigor
  • Variegated types may revert to green

Propagation Tips

Divide rhizomes in early to mid-spring. Cut into sections with visible shoots or buds, and pot up in loamy compost. Grow on until well rooted, then transplant to moist beds or shallow water areas. Self-seeding is rare but may occur in ideal spots.

Maintenance Tips

Trim old foliage in early spring. Remove stray rhizomes or shoots to control spread. In containers, refresh soil and divide every 2–3 years. Deadheading is not needed due to insignificant flowers, but regular thinning helps maintain form.

Did You Know?

Did you know that Houttuynia cordata is edible and used in some Asian cuisines for its fishy flavor? Its common name, Fish Mint, comes from this unusual aroma. Variegated forms add brilliant red, gold, and green tones to water gardens and damp shade beds.
