What could I use with a corn snake???

[Xyon]

Hey, With any animal I keep I strive for for natural settings, its beautiful for us and (in my mind) essential to stimulate the animal in the same way it would be naturally.. its how they've evolved after all!

Here's the question! With my corn, what would you suggest I could use plant wise? I would most likely be inclined to use wood and bark chips as apposed to sand or sphagum. So i was hoping for alot of greenery to counteract this. What kind of greenery would they naturally encounter??
Thanks, Maya
