Elephant Ears Cold Hardy?
I have several elephant ears. Black magic, Illustrious, Black Runner, Green runner, etc. and live in zone 7. I've read that they are cold hardy to zone 7 and I've also read that they are not. Does anybody have the real scoop please?? I'd hate to leave them in the ground with mulch and loose them if they are not cold hardy here in NC
Thanks for any information you can give me.
