I have grown Rotala sp. 'green' in a lot of set-ups, some with extreemely high light intensity and plant reaching surface - but have never yet seen this plant turn red or red-ish.Once mine reached the surface nearly the top leaves went red
May be true . ...... but I'm hopelessly incapable of doing link's (even the ones with my own hands in'em *s*)Mick obviously types faster
There is another cultivar of R. rotundifolia that is mostly orange, but is often erroneously labeled R. indica.Tropica Rotala ‘Green’ has never been anything but green
Tropica Rotala rotundifolia can vary from decidedly green and then pinks/red as it nears the surface ... or it can remain stubbornly green (Mark Evans journal)
