Hi Teresa,
Not being one of my favorites, I haven't paid much attention to it, but suspect it is shade tolerant. The sun is off the pond it is in by noon this time of year, so at most it is getting four hrs sun now.
The problem is Tim, I really just don't like it and as it stands now I wouldn't want it getting out. My wife, the patient one, suggests I hold off on any decision concerning its fate until I see it bloom in the peak tropical months of the late summer.
