Eichhornia crassipes
Water Hyacinth
The Eichhornia crassipes, or Water Hyacinth, is a free-floating aquatic perennial from the Amazon basin. Rounded glossy leaves sit on inflated spongy stalks that work as floats, and the plant sends up short spikes of showy lavender-blue flowers, each marked with a yellow blotch on the upper petal.
It is one of the fastest-multiplying plants in cultivation. Specify it only for fully contained water features, and confirm the destination's import position before it is scheduled, because many countries prohibit it outright.
