Severity: Mild
Staghorn fern is an epiphyte grown for its antler-shaped fronds and its habit of mounting on wood or bark instead of growing in a pot of soil. The ASPCA lists Platycerium bifurcatum, the common staghorn fern, as non-toxic to both cats and dogs, making it a safe pick for households with curious pets.
In Florida, staghorn fern is more than a houseplant — it's a landscaping fixture. UF/IFAS Gardening Solutions notes that the plant "thrives in Florida's heat and humidity" and "grows quite well in South Florida," with Platycerium bifurcatum able to withstand temperatures as low as 30°F, letting it survive well outside the deep tropics with some frost protection. Because staghorn ferns naturally cling to tree trunks in the wild, Florida gardeners follow the same idea at home: UF/IFAS's guide describes mounting a young fern on "a slab of wood, some tree fern fiber, or even a rock," cushioned with sphagnum moss and tied down with "plastic strips, nylon hose, or wire (as long as it's not copper)."
Whether it ends up mounted on a board on a lanai or sitting in a hanging basket indoors, staghorn fern poses no poisoning risk to cats or dogs.
