I think little CHARMANDER IS ADORABLE!!!
I personally stay with pothos, umbrella, and ficus, in that order. Before you use any of them in a cage if you want then to be safe for your chameleon & to survive in a cage here are the steps I use. Take the plant new home accompanied by some organic potting soil and kids play sand.When you get the plant home remove all the dirt you can. I save the dirt for my non-cham plants. Now use a bit of dish soap on your hands and wash all the leaves under running water. It really don't hurt the plant and removes any crap the stores have put on them. Next mix the sand & potting soil 1/2 & 1/2, repot the plant, making sure the pot has several holes in the bottom. Even after all that I still cover the top of my plants with rocks so the cham doesn't try to eat dirt. The mixture of sand & soil will allow the water to run out instead of dirt hopping it all in, that keeps the plants from dying. Also when you buy a ficus they will usual drop lots to all of their leaves, but they will come back, it is just what they often do when you move one of them. Good luck.
