Actiniopteris australis

Eyelash Fern, Mini Fan Fern

Moderate careLithophyteNon-toxic10–20 cm

A tiny fern endemic to Mauritius and Réunion, with delicate fan-shaped fronds that radiate outward like a miniature palm. It grows only 10–15 cm tall and does best in the stable warmth and humidity of a closed terrarium, where its glossy fronds stay green indefinitely. Despite its small size, it is moderately demanding — sensitive to humidity drops and prone to root rot — so it suits experienced terrarium keepers.
