Echinodorus cordifolius 'Tropica Marble Queen'
is a number one choice for the place of honour in the aquarium. The colour
composition of the leaves is very special and goes from deep green over green
to yellowish to produce a marbled leaf surface. However, the marbled look is
usually lost at low light conditions and is therefore suitable for small open aquaria which in general receives enough light. Much
like Echinodorus cordifolius the growth is fast but Echinodorus
cordifolius 'Tropica Marble Queen' tends to stay in the aquatic
environment much longer before it sets emergent leaves. The plant benefits
very much from a nutrient rich substrate and from CO enrichment of the water. The origin of the plant is up to now
unknown but it comes from the Oriental Aquarium in Singapore where it may have
aroused from a hybridisation between Echinodorus cordifolius var. ovalis
and Echinodorus cordifolius 'Gelb'. Alternatively, we have here a
natural mutation.
