Carolina Gardening: Calla lilies...sun or shade?, 1 by DebinSC

Last year I planted some Callas in the "wet" bed that I have that is part sun. I say wet, because it is pretty moist most of the time and ferns and colocasia and cannas and cardinal flowers all love it there. Everything I read about them said full sun so I put them at the sunniest part of the bed -about 4 hours of mid-day sun. They stopped blooming almost immediately, disappeared by late summer, and were not seen again.

Ii gave into temptation today and brought home a "Fire Glow" zantedeschia. Too beautiful to resist. They are labelled "part sun". So here's my question. Anyone growing these down this way, and if so, I'm wondering if 4 hours of sun is too much. I'm tempted to put this one into mostly shade.

Any thoughts appreciated!
