Hyacinth is a free-floating perennial aquatic native to tropical climates. Hyacinths have broad thick, glossy ovate leaves, which have long, spongy bulbous stems. These stems provide a highly durable & flexible fibre. Strings of dried fibres are woven or interlinked together to form a cord. Water Hyacinth plants have many economic uses including bio gas and are ideal for waste water treatment as they have an ability to tolerate high levels of pollution & grow rapidly.
