Mule's Foot Fern (Angiopteris evecta): Massive, Primitive Fern with Huge Fronds

Overview

Mule's foot fern (Angiopteris evecta), also called Madagascar tree fern or Oriental vessel fern, is a colossal, primitive fern native to tropical Asia, Australia, and the Pacific. It produces the **largest fronds of any fern**—up to 20–30 feet long and 6–10 feet wide—arising from a massive, swollen, trunk-like rhizome (the "mule's foot") that can reach 3–4 feet tall and wide. The fronds are bipinnate, fleshy, and bright green, with a distinct, swollen base (pulvinus) at each pinna junction.

Primitive Grandeur

• Record Fronds: Among the largest leaves in the plant kingdom.
• Ancient Lineage: Family Marattiaceae dates back 300+ million years.
• Cultural Uses: Starchy rhizome eaten in some Pacific cultures.

Culture

Deep shade to filtered light. **Constantly wet, rich, deep soil**—often grown near water features. Requires vast space; not for small gardens. Frost tender; USDA zones 10–12 only. Botanical garden specimen.
