Common questions

Aren’t some ferns dangerous?

Yes — asparagus fern (a relative of asparagus, not a true fern) causes vomiting and skin irritation, and bracken fern is toxic to grazing animals. Maidenhair itself is safe.

Why does my cat shred the fronds if they are not tasty?

Fine, wispy fronds trigger play behavior. The plant is safe but fragile, so a hanging spot protects both the fern and your floor.
