There are seven species of water hyacinths which make up the genus Eichhornia. They are free-floating perennial aquatic plants which are native to tropical South America. The leaves are 10-20 cm across and to keep the plant floating they produce bulbous stalks. The roots are freely hanging roots and looks like feathers. Beautiful flowers are born on a single spike which consist of 8-15 flowers.
Water Hyacinths are not very popular since they hold the honor of being one of the fastest growing plants known. These plants reproduce two ways by runners and seeds. The water hyacinth (Eichhornia crassipes) is a vigorous grower known to double its population in two weeks.It has been widely introduced throughout North America, Asia, Australia and Africa. This pernicious invasive species was known to once choked Florida’s waterways. If this plant is not controlled it will cover lakes and ponds entirely.
