Rotala sp. colorata

This plant was introduced with the name Rotala sp. 'Colorata' and is apparently a form of the very variable species R. rotundifolia. There are several forms of R. rotundifolia in trade that attain a more or less intensive red colour when cultivated submersed, e.g. the plants erroneously sold under the name "Rotala indica". R. rotundifolia 'Colorata' turns a reddish hue even under moderate light. Under strong light it develops a pretty red coloration.
