Lilaeopsis brasiliensis is a short-stemmed plant that can be grown as a carpet in an aquarium. It is found throughout much of Brazil, and it grows both fully submersed and partially submersed on the banks of rivers and streams.It will grow to a maximum size of 3 inches (7.5 cm) in a home aquarium, and will form a dense and impressive carpet if it is provided the right mix of CO2, nutrients and lighting. This can be a somewhat difficult plant to grow, and should only be attempted by aquarists who have some experience with aquatic plants.
Lilaeopsis brasiliensis can grow very densely, but it only grows like a lawn under very intensive light. When planting, make small tufts and put them into the ground with a distance of only a few centimetres, as the plants form an uninterrupted lawn more easily this way. The planted area should be without shade so the plants get sufficient light. Also suitable for a garden pond, and it tolerates the low salinity of a brackish water aquarium.
