Giant Salvinia
Giant Salvinia
Salvinia molesta
Floating
16 -28 °C (60.8-82.4°F)
Max Height
20 cm (7.9")
Max Width
50.8cm (20 ")
Alternative Names[edit]
- Giant Salvinia
Origin[edit]
- This is native to South-Eastern Brazil.
Environment Specifics[edit]
- The Giant Salvinia is a tough floating plant that is mainly found in still pools and rivers.
Identification[edit]
- It is a free floating plant that does not attach to the soil, but instead remains buoyant on the surface of a body of water. The fronds are 0.5-4cm (0.2-1.6") long and broad, with a bristly surface, and produced in pairs also with a third modified root-like frond that hangs in the water.
- It reproduces by asexual reproduction only, but it is capable of growing extremely quickly, starting from small fragments and doubling in population size every few days, with the result that the surface of ponds, reservoirs, and lakes are covered by a floating mat 10-20 cm (in some rare cases up to 60 cm) thick. As a consequence, it has sometimes considered an invasive weed in some parts of the world. The plant's growth blocks sunlight needed by other aquatic plants and especially algae to oxygenate the water.
- A tiny weevil, Cyrtobagous salviniae, found in the native distribution of S. molesta, is currently being studied as a biological pest control.
