Accession Data:
Eichhornia crassipes (Mart.) Solms
- Common Name: Water Hyacinth
- Family: Pontederiaceae Kunth.
- Country of Origin: Amazon basin; widespread invasive elsewhere
- Habitat: free-floating perennial aquatic plant (or hydrophyte)
- Description: One of the fastest growing plants known, water hyacinth reproduces primarily by way of runners or stolons, which eventually form daughter plants. Each plant can produce thousands of seeds each year, and these seeds can remain viable for more than 28 years. Some water hyacinths were found to grow up to 2 to 5 metres a day in some sites in Southeast Asia.3
Azotobacter chroococcum, an N-fixing bacteria, may be concentrated around the bases of the petioles but doesn't fix N unless the plant is suffering extreme N-deficiency (Matai and Bagchi, 1980).
