Johns personal favorite aquarium plant. The Latin name means "the plant with the round leaves'', but this only applies to the marsh variety, which has circular leaves. Rotala rotundifolia from South-East Asia has 6-12 inch long stems (3/4-1 inch wide) and long, narrow 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. Also known as Rotala indica.

Pots are brimming with plants and have lots of mass and healthy,
well-developed roots.
Most pots can be divided into several portions or individual plants which are planted separately.
