The Latin name means "the plant with the round leaves''. But this only applies to the marsh variety, which has circular leaves. Available in either a grown on rooted plant, or as a smaller Mini Pot that is grown in a coconut fibre casing, which can be planted directly into the aquarium.
Rotala rotundifolia from South-East Asia has long, thin leaves and 15-30 long stems, 2-3 cm wide including the leaves. Unlike other Rotala species it is relatively undemanding, although it needs good light to produce red leaves. It forms side shoots willingly, becoming compact and bushy. This also means that it is hard for light to reach the lower leaves, so the plant should be pruned frequently
