1, water lily

Water lily (scientific name: Nymphaea? L.), perennial aquatic herb; rhizome fat. Petiole cylindrical, slender. Leaves elliptic, floating in the water, entire, leaf base cordate, leaf surface green, dark purple on the back. Leaves dimorphic: floating leaves rounded or ovate, base with curved notch, cordate or arrow-shaped, often without emergent leaves; submerged leaves thinly membranous, fragile. Flowers solitary, floating in or out of water.

2, the water hyacinth

Floating herb, 30-60 cm high. The fibrous roots are well-developed, brownish-black, up to 30 centimeters long. The stem is extremely short, with long stolons, stolons light green or purplish, separated from the mother plant grows into a new plant.

3, duckweed (Lemna minor), also known as: green pimpernel, pimpernel, pimpernel grass, water pimpernel, water pimpernel grass, is pimpernel family water surface floating plants. Prefer warm climate and humid environment, avoid cold.

Floating plants, also known as completely floating plants, is not born in the bottom of the mud, the whole plant body floating on the water surface of a class of floating plants; these plants are usually undeveloped roots, the body has a well-developed aeration organization, or with an expanded petiole (air sacs), to ensure gas exchange with the atmosphere. Such as locust leaf pimpernel (Salvinia natans), floating pimpernel, bromeliads and so on.

Floating aquatic plant species are less, this kind of plant's root is not born in the mud, the plant floats above the water surface, with the current, wind and waves around, most of the foliage-based, for the pool to provide decorative and green shade. And because they can both absorb minerals in the water. At the same time can shade the sunlight into the water, so also be able to inhibit the growth of algae in the water body.

Floating plants grow quickly and provide shade decoration on the water's surface more quickly. However, some species grow and multiply particularly rapidly and may become a nuisance in the water. That's why you need to fish some out with a net on a regular basis. Otherwise they can cover the entire surface of the water. Here are a few of the most common floating aquatic plants.
