Q1) What is Water hyacinth?

Water hyacinth (Eichhornia crassipes) is a large aquatic plant native to the Amazon basin. Its thick, waxy, oval-shaped leaves are 4-8 inches across and branch out from the center of the plant on modified stems that may rise as much as 1 meter above the water surface. Water hyacinth is one of the most noxious weeds in tropical and subtropical regions.
