Giant Salvinia (aquatic nuisance plant)

Giant salvinia (Salvinia molesta) is also known as Kariba weed, African pyle, aquarium watermoss, koi kandy. This plant is one of the worlds most noxious aquatic weeds and is notorious for dominating slow moving or quiet freshwaters. Its rapid growth, vegetative reproduction and tolerance to environmental stress make it an aggressive, competitive species known to impact aquatic environments, water use and local economies.

Giant salvinia is native to South America and has been introduced to several countries around the world (including the US). Giant salvinia has been found in Georgia at four locations since 1999.
