In contrast to "standard" R. rotundifolia, R. sp. "Green" never turns reddish but keeps its fresh green colour even under very strong light. The plant has an attractive bushy elegantly overhanging growth habit. Occasional thorough trimming is recommendable, as this plant is a very fast grower. Amano masterfully uses the characteristic overhanging growth habit of this Rotala in many of his aquascapes. This plant that entered the aquarium plant trade as Rotala sp. "Green" is apparently a form of the very variable species Rotala rotundifolia. The characteristics of the submersed form of R. rotundifolia "Green" are: - purely green colour of leaves as well as stems, - a weeping habit (at first, the shoots grow upright, but then bow down), and - always only 2 (not 3 or more) leaves per node.
