Marsh seedbox (Ludwigia palustris)

The marsh seedbox (Ludwigia palustris) is an aquatic perennial herb that thrives in moist, waterlogged environments, such as wetlands and riverbanks. It is often used in aquariums due to its preference for submerged conditions. In Australia, it is deemed invasive because it can quickly dominate and overshadow native flora, disrupting local ecosystems. Its rapid growth and spread can also interfere with water flow and quality, posing a threat to aquatic habitats and biodiversity.
