What is Water hyacinth?

Water hyacinth also known as Eichhornia crassipes is really fucking up the US we need to get rid of this. A little about Water hyacinth, it is a free-floating perennial aquatic plant (or hydrophyte) native to tropical and sub-tropical South America. With broad, thick, glossy, ovate leaves, water hyacinth may rise above the surface of the water as much as 1 meter in height.
