"corn plant" is a form of _Dracaena fragrans_, and is probably safe, but its not an ideal plant for lizard environments; it has fiberous foliage that could result in impaction if eaten in large amount, and the young leaves are so fragile that constant climbing on them would result in a ragged-looking plant.
Often, this plant is listed in books as _D. massangeana_ which is not botanically valid.
