Croton - tri color - bush on fire

I planted five of these in a sunny spot in my yard in zone 8b, south central Louisiana. Should I dig them up and keep indoors this winter or should they fair ok? I really like them and would hate to loose them.

I kept mine in a pot in my heated greenhouse and it STILL died - I'd suggest you take them inside your house for the winter.

eewwww... not good.
