Rotala sp. 'Nanjenshan' and the R. sp. 'Green' hang over. The R. mexicana 'Goias' grows prostrate.
Most of the rest grow pretty much like the colorata. R. mexicana 'green' and ramosior are more erect and less branchy. You could also use Pogostemon erectum, which looks a lot like some Rotalas, and was passed around as one for a while.
