It is a native of Central and South America that was introduced into the southern United States in the 1920’s or 1930’s. One, Salvinia collada, is a great plant if you’re looking for slower growth. The species continued to be introduced to other warm regions of the world intentionally as an aquarium and water garden plant, and unintentionally as a contaminant in shipments of other aquatic plants (Oliver 1993; Nelson 1984). http://www.calflora.org/.

Cytologia 31(3):330-338. Salvinia's growth, expressed as frond production and plant fresh weight doubling time, was significantly increased with increasing nitrogen concentration from 1.0 mg/1 to 100.0 mg/1 in the growth media. 3rd edition. 1975.

Johnson, D. 1995. Salvinia minima produces excessive surface growth, which can impede waterways and restrict boating. Salvinia molesta belongs to a group of closely related Neotropical species that share the feature of eggbeater type hairs (Mitchell 1972; Mitchell 1979). Four hairs are joined at the tips and resemble a wisk. Mitchell, D.S. The Journal of Applied Ecology 12(1):213-225. and N.M. Tur. Sam Rayburn catches case of giant salvinia. Accessed on 11/20/2015. Inter- and intraspecific interference within cultures of Lemna spp. and P.A. Aqueous extracts of cattail plants (roots, stems, and leaves) as well as two of its phenolic compounds (2-chlorophenol and salicylaldehyde) were found to inhibit the growth of Salvinia when incorporated in the growth medium. Madsen, J.D, R.M. It is a small, rapidly growing species that can become a nuisance due to its explo-sive growth rates and its ability to shade underwater life (Oliver 1993).
