I voted for fake since this is a corn board, and it is much easier to take out the fake plants and wash them off/sterilize them as needed. I don't use any real plants with my corns.
Having said that, in enclosures where I need to keep the humidity up such as with our chameleon, anoles, frogs and toads, as well as our MHD we do use real plants. Mostly pothos as it is safe and sturdy, but a few others too like ficus with the chameleon.
