Overview
Platycerium bifurcatum is the staghorn fern, growing 24-36 inches (60-90 cm) when mounted. The species produces two distinct frond types: (1) gray-green, thick, forked (bifurcating) fertile fronds that project outward, resembling deer antlers (the species name 'bifurcatum' means 'twice-forked'); and (2) flat, round basal shield fronds that press against the mounting surface, collecting water and organic debris. Shield fronds turn brown as they age and are replaced by new green shields growing over them; the brown shields are living tissue and must not be removed. Epiphytic: grows on tree trunks in nature, not in soil. Typically mounted on wooden boards, bark slabs, or hung in wire baskets lined with sphagnum moss. Watered by soaking the entire mount in a bucket or running under a shower for several minutes, then allowed to drain completely. More drought-tolerant than thin-fronded ferns; the thick fertile fronds and shield structure reduce water loss. Non-toxic to cats and dogs. Native to Australia, Southeast Asia, and Polynesia. The mounting requirement and two-frond-type structure separate the species from other commonly grown ferns.
