Microsorum — 13 species

Microsorum is a genus of tropical ferns — including the popular Crocodile Fern, Giant Wart Fern, Commutatum Fern, and Hound's Tongue Fern — known for their textured, glossy fronds that range from deeply ridged to broadly strap-shaped. They grow best in bright to moderate indirect light and prefer consistently moist but never waterlogged soil; water when the top inch feels barely dry. Toxicity varies across Microsorum species: while many, including the Crocodile Fern, are considered non-toxic to pets, not all species have been individually assessed, so check the safety status of each specific species before purchasing for a home with cats or dogs.
