Overview

Ludwigia sedoides is native to South America, primarily Venezuela, Panama, Columbia, and Brazil, and introduced to Lesser Sunda Island and Thailand. It is an ornamental aquatic plant recognized as a potential invasive plant in Sri Lanka. Genus epithet 'Ludwigia' is named after German botanist and professor of medicine, Christian Gottlieb Ludwig (1709-1773). Species epithet 'sedoides' means 'resembling sedum', a reference to the leaves which resemble those of certain Sedum species in terms of appearance and colour changes under strong light. It has environment benefits such as a natural source of filtration for your water, improving water clarity, quality, and health the safe, eco-friendly way. Floating leaves provide protection from predators and improve water clarity by limiting direct sunlight.

Agroecology

Mosaic plant found in standing pools of water with leaves floating on surface, or growing in very swampy wet soils. It needs pH to be below 8 to survive, as it does not tolerate water with high pH. It is a very unique water garden plant that will spread well in warm water.  It requires full sun to part shade and thrives in warm, sunny, damp conditions. Suitable for ponds or containers with 30-60 cm depth. Plant needs to be rooted in substrate below water surface. Avoid mixing with fish, as brittle stems make plant susceptible to being torn apart by fish.

Morphology

  • Roots - fibrous root.
  • Stems - reddish, brittle.
  • Leaves - mature leaves are smooth, glossy, simple, opposite, diamond-shaped with toothed margins, radiate outwards to form mosaic-like rosettes. Edges of central and older leaves turn bright red when plant is grown under bright light. Leaf rosettes are fully extended during daytime with gaps in between leaves. At night, the rosettes contract such that the leaves overlap one another.
  • Flowers - bisexual, bright yellow, cup-shaped, solitary, produced in leaf axils from June to August in native habitats.
  • Fruits - explosive capsules.

Cultivation

  • Generative propagation is by seed.
  • Vegetative propagation is by stem cutting, and division.
