Boston Fern
Nephrolepis exaltata
Family Nephrolepidaceae
A Boston fern in a porch basket is instant Southern-veranda atmosphere: three feet of arching, feathery fronds that move with every breeze. Few plants soften a room or an entry so completely, and fewer still have been doing it since your great-grandmother's day.
Summer on the shaded porch, winter in a bright bathroom where it drinks the shower steam — that's its happy annual commute. Completely pet-safe, honest about shedding a leaflet or two. Hang one where you sit in the evening and let it do the decorating.

Questions
Boston Fern questions, answered straight.
Is boston fern safe for kids and pets?
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.
