Echinodorus

Most echinodorus are paludal plants, but they can also survive underwater. The shape of the leaves depends on the conditions under which they are cultivated, which can range from slightly acid to neutral water, and low to moderate hardness. These plants turn yellow when they lack iron, so you must ensure that there is an adequate supply. You can reproduce them by taking a cutting of a rhizome on which seedlings have appeared.

Echinodorus amazonicus

Under good conditions (moderate to strong lighting), the Amazon grows to 40 cm. If the water is too hard it is markedly smaller and appears to stop growing.

Echinodorus maior

The giant echinodorus reaches the same height as its Amazonian cousin and, like it, is worth highlighting in a large aquarium if it is the only representative of its species. Size: 30-40 cm.

Echinodorus maior

Echinodorus quadricostatus

The dwarf Amazon serves to decorate the foreground of an aquarium. It prefers a moderately rich soil, and tolerates temperatures under 20°C. The shape of the leaves varies according to the lighting. Size: 10 cm.

Echinodorus tenellus

The pygmy Amazon, the smallest of the genus, prefers soft water. It can rapidly accumulate an extensive covering of runners. It does not like too many fine muddy particles round its base. Size: 10 cm.
