There are ten species of salvinia in the world and the water fern, Salvinia minima, is the species that occurs in Florida. Current practice is to leave the wet plants on shore to dry and then bury the dessicated plants. It can grow in semi-shade (light woodland) or no shade. Medicinal plants are under cultivation and cultured world over. It spreads aggressively by vegetative fragments. Mitchell) growing in three outdoor research ponds survived two north Texas winters during 1999-2000 and 2000-2001. aquatic … And, while the leaves of young plants lie flat on the water’s surface, the leaves of mature plants grow to be between 1/2 and 1 1/2 inches long (1.27 Google Privacy Policy | Salvinia molesta invasions can alter wetland ecosystems and cause wetland habitat loss. S. molesta exhibited the highest antioxidant activity. Exhibits great variation in form and structure depending on habitat conditions such as space and nutrient availability. Botanically, say a thousand years ago, these were wild and many of them were weeds. There are 10 species of Salvinia in the world, none of which are native to the United States.
