Rotala rotundifolia “green”
This small-leaved species has an attractive, delicate appearance and is ideal for planting in groups in the back or midground of the aquarium. Lighting should be relatively strong. Given bright light and sufficient nutrients, the leaves may change from olive green to pinkish color towards the top of the plant. Cuttings should be at least 4 in (10 cm) long to ensure good growth.
The plant is adaptable to moderate light and lower temperatures, although growth will be slowed. A few leaf shape varieties are available. Although the leaves are small and the distance between them (the nodes) is large, if planted in groups, this plant will appear quite dense.
