Common questions

Can I keep a button fern in a dog-accessible spot?

Yes, safety-wise. Practically, ferns dislike rough handling, so a hanging planter keeps both dog and plant happier.

What ferns should I avoid with a dog in the house?

Skip asparagus fern (vomiting, skin irritation) and anything sold as a fern that is really a cycad, like sago palm — which is lethal. True ferns including button fern are safe.
