Water Hyacinth consists of seven species types which are all native to South America. It is one of the fastest known growing plants. It can double it's population in 2 weeks. They can become a major problem when not properly controlled creating breeding grounds for mosquitoes and using up valuable natural resources.
i have tried to grow a couple of species of floating Eichornia. i would not say that their aquarium culture is "easy". the plants that i had all declined over time. i think that it is difficult to provide the bright light that they require in a tank.
