Description and Ethnobotany

Others - Plant Morphology Aquatic herbaceous shrub. Found in standing pools of water with leaves floating on surface, or growing in very swampy wet soils. Stems reddish, brittle. Leaves 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 bright yellow, cup-shaped, solitary, produced in leaf axils from Jun to Aug in native habitats. Fruits are explosive capsules.Suitable for ponds or containers with 30-60cm 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.Genus epithet 'Ludwigia' is named after German botanist and professor of medicine, Christian Gottlieb Ludwig (1709-1773). Ludwig corresponded with Carl Linnaeus (father of modern botanical taxonomy) about plant classifications, and Linnaeus dedicated the genus 'Ludwigia' in honor of Ludwig. 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.
