They don't eat plants and are no more likely to be poisoned by a house plant then we are. Reptiles in general are not necessarily affected by the same thing we are. Box turtles for instance prefer mushrooms that would be toxic to us, and Green Iguana's love plants high in calcium Citrate, which if you have ever been temped to see what skunk cabbage taste like, its like eating thousand of little needles, trust me, it sucks! Anyway the point is that our knowledge of dangerous plants is based on human responses not reptiles, so there are no guarantees. In general stay away from anything with a strong scent, or that produces pollen. I keep many ivys, ficus trees and other such plants with mine and are just fine.
