Heteranthera holly

Heteranthera holly, scientific name Heteranthera zosterifolia. It comes from the Amazon River in Brazil, grows in swamps and other bodies of water with stagnant water. It has been used in aquaristics for a long time and has established itself as an unpretentious and hardy plant. Previously widely used in Dutch, now in Nature aquariums. Depending on the size of the tank, it can be used both in the foreground and in the background, contrasting favorably with other plants.

Heteranthera holly serves as an excellent indicator of the composition of water. With a lack of nitrogenous compounds (nitrates), foxes become translucent, lose color. In the “old” water with an abundance of phosphorus, a plant from light green becomes dark.

Not demanding on the mineral composition of substrates and other growing conditions. However, under bright light, additional introduction of carbon dioxide and the introduction of special fertilizers, it acquires large leaves, growth accelerates, and blue flowers may form when it reaches the surface.
