Rotala 'Bonsai' is best described as a compact, moderate growing version of Bacopa caroliniana. Plant in small groups and trim often. Cuttings may be re-planted in the group to achieve a more dense group or carpet.
At high light may the tip of the stems become reddish, at lower light will the leaves become larger and the plant less compact.
Rotala ‘Bonsai’ are particularly suitable for nano-aquariums.
