peace lily and bamboo are fine, you can also use silver queen, diffenbachia, philodendron, pothos, arum, ivy, ferns, spider plant, etc. most types of tropical house plants and succlents (without spines) are fine to use in vivariums. you can check Black Jungle terrarium supply for a list of what they sell. most garden centers will be able to help you out, just tell them you need non sapping, non toxic house plants with broad leaves and strong stems.
