This attractive plant variety from Brazil is called Staurogyne repens, a member of the acanthus family. It looks a bit like a miniature Hygrophila but is an outstanding plant for the foreground. It grows very slowly and, under good conditions, will crawl across the substrate. Staurogyne demands intense light and a good supply of nutrients via the substrate. Regularly trimming the shoot tips will force the plant to push out a lot of new horizontal shoots, and will eventually give you a very nice, thick stand of plants. For aquascaping purposes, these beauties mix well with Hemianthus callitrichoides.
