The water hyacinth Eichhornia crassipes (Mart.) Solms of the Pontederiaceae family is a free-floating perennial water-loving plant that grows as a weed in subtropical areas, but is extremely attractive in aquariums or other water bodies. His homeland is the Amazon Basin. It has a rosette of thick, leathery ovate leaves, and each flowering class usually has 8-15 flowers. One petal of each color has a yellow spot at the base. As an ornamental aquatic garden plant, water hyacinth provides attractive flowers and dense greenery that inhibits the growth of algae and helps keep water clean.
