Didiplis diandra is a delicate and difficult
but also very beautiful aquarium plant with opposite leaves in rows of two.
In its' natural habitat of Northeast America
it occupies the banks of rivers and lakes where it develops both submerged,
floating and emergent shoots. It does not resemble any other aquarium plant,
and thus it creates a very conspicuous contrast when planted in groups of 3-5
shoots in the foreground or in the middle of the aquarium. On the other hand,
they should not be planted too close to each other since the lower leaves are
then lost due to light deficiency. As a rule of thumb, D. diandra is
offered enough light only when the leaf apex is coloured red. D. diandra
prefers a fine-grained substrate and CO
enrichment of the soft and acid water is absolutely necessary to assure
optimum growth. D. diandra may be reproduced by cuttings.
