R. rotundifolia is an easy red plant to grow in the aquarium. While it will grow in medium light, this plant really needs high light to show its true colors.

To propagate, simply snip off a healthy stem and replant into the substrate. Pruning off the top portions of this plant and leaving the rooted portions in the substrate promotes very bushy growth as the plant should produce a multitude of side shoots. Pruning can also be done by discarding the rooted portions and planting the top portions into the substrate. If allowed to grow on the surface, the plant will also produce many side shoots from each node along the stem.

In aquascaping, this versatile plant can be used in the mid ground and background positions as a focal point or reddish accent.
