pierced-leaved pondweed

The pierced-leaved pondweed, the scientific name is Potamogeton perfoliatus. The plant is widespread on almost all continents (with the exception of South America and Antarctica) in the temperate climate zone. Found in Europe and Asia. It grows in lakes, swamps and other reservoirs with stagnant water, rich in nutrients, at depths of up to several meters.

It is a completely aquatic plant. Forms a creeping rhizome from which grow long erect stems with linear blunt leaves located singly on each whorl. The leaf blade is translucent, 2.5–6 cm long and from 1 to 3.5 cm wide. In nature, Pompus piercedis can grow up to 6 meters in height. When reaching the surface, it forms a short spikelet about 3 cm in length. Unlike other closely related species, there are no floating leaves.

Due to its size, it is primarily considered a pond plant rather than an aquarium plant. Applicable only in very large tanks for placement in the background. Unpretentious, perfectly adapts to various hydrochemical conditions and water temperatures. For healthy growth, nutrient soil of sufficient depth (20–30 cm) is required.
