Kochuripana or Water hyacinth (Eichhornia crassipes, family: Pontederiaceae) is an aquatic plant with short stem and is native to tropical and sub-tropical South America. It may rise above the surface of the water as much as 1 meter in height. The free-floating perennial is found in the rivers, canals and ditches in Bangladesh.

Common names: Water hyacinth, Floating water hyacinth, Lilac devil, Nile lily, Water orchid, Water violet.

Broad, thick, glossy leaves are ovate or rhomboid, glabrous, 10-20 cm across, that come out from the stem. Root is fibrous, freely hanging, purple-black in color.

Inflorescence is long and erect, bears of 8-15 conspicuously attractive flowers with six mauve or purple-colored petals (each up to 4 cm long), mostly painted with yellow and violet colors. 

In Bangladesh, it is regarded as the most troublesome aquatic weed to crops and water-transportation. Some parts of the plant, especially the green parts and flowers are eaten as vegetable in Southeast Asia. The aquatic plant is also used as animal feed.
