HISTORY
Picture by USDA
This South American native was introduced into Florida in the 1880s. It is believed that the water hyacinth was introduced first into the United States at the World's Industrial and Cotton Centennial Exposition of 1884-1885 in Louisiana. A Florida visitor to the Exposition apparently returned home with water hyacinth plants and subsequently released them into the St. Johns River. From there it spread rapidly spread to neighboring states. Water hyacinth has been in Africa, starting in the River Nile, since the 1870's . Today you can find it in all warm, tropical places. But, people have brought water hyacinth in colder regions too. Today some places, like Texas, do not allow you to have water hyacinths because they are afraid it will spread all over the lakes and rivers.
