About Elephant Ear Staghorn Fern

Platycerium elephantotis · also called Elephant Ear Staghorn Fern, Angola Staghorn · houseplant

Platycerium elephantotis, from tropical Africa, is the staghorn that breaks the antler mould: its broad, rounded, undivided fertile fronds look like elephant ears rather than horns, paired with wavy upright shield fronds. An epiphyte grown mounted or in a basket, it likes warmth, bright indirect light, good airflow, and a soak-and-dry watering cycle.

Preferred mix: Soilless epiphyte substrate
