More SUN, I would ink.

Thank you papnnana for your reply. The side of the falls that I have the new thalia on actually gets more sun than the other side where the previous thalia was located (the one that bloomed). It's hard to see now but I have annual cannas planted in a pot on the top of the falls and they are blooming. They're just overwhelmed by the elephant ears in the bog at the moment. When the picture was taken the thalia was in full sun. To me the thalia doesn't look spindly at all as it might in less light.
