Would love to hear what you find if you get the chance to move it back into sunnier conditions. I have noticed things going both ways too, and was getting curious about one (Tooth) that is doing better on all points in a sunnier spot than its unimpressive performance last year in shade. And, it is surprising me with polys in the sun! A very interesting idea, and so far, the only polys I've gotten (on a number of cultivars) have been in the sunny beds. Hmm.
