Lemna (Latin Lemna) can be called as duckweed small, frog sackcloth, duck grass. Belongs to the Aroid family, a genus of flowering monocotyledonous plants. There is speculation that duckweed carpet clogs water, but this is not the case. Thanks to the production of oxygen, the plant enriches the surrounding space with it.
Where it grows and what duckweed looks like
This grass is found in any standing water bodies, especially with a variety of organic living creatures that provide duckweed with food. Thin sheet plates float on the surface of the water. The roots departing from them, acting as a keel, are under water. Depending on the type of duckweed, the leaf has a different shape and size. At its base, a small inflorescence may appear.
In the autumn, when the temperature drops to +6 degrees, the grass prepares for the formation of future sprouts, forming special buds. Then it sinks to the bottom, where it remains until spring.
The plant is very unpretentious and is characterized by rapid growth, especially in polluted water. It can tolerate very low temperatures and difficult climatic conditions, but prefers a temperate and tropical climate.
Common types of duckweed
There are many species of this flowering plant, but they all float freely in the water column or on its surface.
