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
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.
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.
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.
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.
