Nenuphar (yellow lily, kubyshka, nuphar lutea  is a perennial aquatic plant known since ancient times. The kubyshka belongs to the Nymphaeaceae family. In common parlance, the plant is often called a water lily. 

Its unique ability to develop simultaneously in three environments: soil, water, and air has fascinated us with its nature. It has a long creeping rhizome, colored yellowish-green. 

The flower itself appears in late spring or early summer. It is attached to a long, thick stem and often rises slightly above the water. In some regions, flowering continues throughout the warm season. After flowering, a fruit is formed, which really resembles a small jug in shape, hence one of the names of the people is yellow jugs or cubushka. It contains seeds. When the seed box is opened, the seeds drift on the water or are eaten by birds. Thus, the plant reproduces and conquers new territories.
