Donna, I have had the same experience with my acanthus and have wondered the same as you. I had one "Summer Beauty" which did fine for 2 seasons; well, it bloomed and grew a bit, but this year it's very puny and pale. The other two that I have are supposedly a "southern" variety, though I can't recall the name. They have struggled for 3 years. I have one in full shade, and the other two in part shade. All the same.
I've had better luck with Callas, though some varieties have done better than others. The ones doing best are in a very wet, boggy spot in soil with lots of clay. They get high shade in the morning, a little direct sun at mid day and heavy shade in the afternoon.
