I know you were probably looking for live plants, but I thought I would offer that medium size fake shrubbery can be found at places like hobby lobby. I found them really convenient because not only do they look pretty realistic, but you can maneuver the bendable branches how you like and they really fill the larger enclosures nicely. They also seem to offer better support than the live plant I tried (my cham avoided it.) I washed mine really well, removed the decorative basket base, and actually submerged the tree in the tub for a long while to make sure the leaves had no potential dye seepage. I also have live pothos in there but mostly the small tree gets used for basking and climbing. I will add the disclaimer that I'm new to all this and I can't tell you if there are any bad sides to having fake trees. I'm sure someone will chime in if they have had bad experiences.
Oh, and best of all, they don't drop leaves or die, or get overwatered.
