Questions
Boston Fern questions, answered straight.

Boston Fern is commonly eaten and isn't considered toxic, but "commonly eaten" isn't a guarantee for any particular person or animal — allergies, quantity, and which part you eat all matter. One caveat on this one: Safe for pets. Never eat a plant you haven't positively identified, and check with a vet before letting pets or livestock graze anything new.
