Pronunciation

When I was a kid, I'd look up words to see if I was saying it wrong or the person on television or wherever I'd heard it. I still do that. Today I looked up "peony" because everybody around here calls it "pea ON ee). I wanted to know if that is an accepted pronunciation according to the dictionary. It wasn't listed as an acceptable pronunciation in the online dictionary I used. If it had been listed, I would have tried to say it that way. But it wasn't. So, of course, I then had to decide if I should mispronounce it to avoid sounding like I'm "different." Can't quite get there. They are just going to have to think I'm wrong since obviously if all of them say it that way, I'm the wrong one.
