The plant grows at an astonishingly rapid rate; because it is asexual, it is able to reproduce without relying upon insect or wind pollination for fertilization.

Provided it has the correct conditions for growth, including a warm temperature and a high moisture level, the water hyacinth can reproduce almost constantly, covering huge areas, such as the surface of a lake. The leaves of the water hyacinth are another noticeable characteristic. The leaves of the plant contain air-filled tissue, which gives the plant its unusual buoyancy, allowing it to float completely unsupported.

The stems of the plant are filled with the same tissue, which allows the stems to support the leaves without dropping below the surface of the water. Leaves are 10 to 20 cm across, much larger than the flowers, and float above the water surface.
