Maidenhair Fern vs Boston Fern
Adiantum raddianum vs Nephrolepis exaltata
Two pet-safe ferns at opposite ends of the difficulty scale — Maidenhair is famously fussy, Boston Fern is forgiving.
Maidenhair Fern (Adiantum raddianum) and Boston Fern (Nephrolepis exaltata) are both non-toxic to cats and dogs per the ASPCA, and both want high humidity. The similarity ends there. Maidenhair Fern is one of the most challenging houseplants you can buy — it crisps within hours if humidity drops below 60%, demands constant moisture, and forgives nothing.
