R. pusilla is R. sp. 'Araguia'. Mine grows straight up, and low NO3/PO4 does indeed make the stems appear a bit darker.Cavan Allen said:How big do your stems get Aaron? I just got some recently, and it's roughly the size of rotundifolia. I'm sure I've seen pictures of it larger, so I'm hoping to get some more size to it. It's a very nice plant in any case.
Have you been able to grow stands of it like with rotundifolia?
I'm pretty sure this is one of the two Rotalas called "Rotala sp. Araguaia".
