Are any of your plants poisonous to children?

Some are. Many popular houseplants, including most aroids such as Monstera, Philodendron and Alocasia, contain calcium oxalate crystals that cause a burning mouth and stomach upset if chewed. They are not pleasant but are rarely dangerous. A few, such as Euphorbia, have an irritant sap.

Where a plant is known to be toxic we say so on its page, and our Pet safe collection is a good place to start for homes with small children too. If a child eats part of a plant, rinse the mouth, offer water and call NHS 111 with the plant name.
