The story of Water Hyacinth is similar in many countries. It occurs naturally in * sub-tropical and tropical America, in Venezuela being called "Ear of a Mule" or "little Boat." Plants were first introduced to the United States of America in 1884, and excited great admiration. Many visitors to the Floral Exposition in New Orleans carried away plants to their gardens and pools. Surplus material was thrown into creeks and within a short period Water Hyacinth was carried through the waterways of Florida. To quote Dr. P. W. Zimmerman—"The rapid spread of Water Hyacinth in the Southern States, with its adverse effects on agriculture, health and wild life and its interference with drainage and navigation has been an alarming problem for many years."
