Water hyacinth (Eichhornia crassipes)
Family: Pontederiaceae
The water hyacinth is one of the world's most problematic invasive plants. With incredibly fast growth, colonies of Eichhornia can double in size in under two weeks. The plants float freely, allowing them to spread by wind and current. Native to South America, they have infested the waterways of nearly all subtropical and tropical regions. Cultivation of water hyacinth is prohibited in many locations. Nevertheless, they are attractive summer pond plants that are suitable for areas too cold for them to overwinter.
