Pteris Ensiformis

The Silver Ribbon Fern

What Is Pteris ensiformis?

Pteris ensiformis, commonly known as the Silver Ribbon Fern, is a tropical fern admired for its slender fronds and light variegation. The name ensiformis means “sword-shaped,” describing its narrow, pointed leaf segments.

It grows naturally in warm, humid forest environments, often on the ground or in rocky, shaded areas. It is not an aquatic plant and should never be submerged.

This fern is popular as an indoor ornamental plant because of its elegant shape and soft silver-green tones.

Light and graceful, Pteris ensiformis adds gentle texture to indoor tropical collections.
