It's surprising how many toxic or poisonous plants are kept in the home for ornamental value, from delicate peace lilies and calla lilies to many species of succulent euphorbias. Luckily there are many non poisonous indoor plants that can be kept inside the home without causing potential harm to kids and pets.
