Black Tree Fern

The Black Tree Fern (Cyathea medullaris) is a striking evergreen fern native to several Pacific Islands including Chatham Island, Fiji, Marquesas, New Zealand North and South Islands, Pitcairn Island, Society Islands, Tubuai Island, and Vanuatu. This tree-like fern can grow up to 9 meters tall and thrives in partial sun to shade with moist, wet conditions and light to heavy soil types. It belongs to the Cyatheaceae family and is known for its edible leaves and stems, which are often used in local cuisine. The Black Tree Fern's distinctive feature lies in its ability to form a trunk-like stem, giving it a tree-like appearance while still being classified as a fern. The plant can be propagated through spores or by dividing established plants. It thrives in zones 8-11 and is hardy in these warmer temperate regions. For optimal growth, keep the soil consistently moist to support its partial sun/shade requirements. The Black Tree Fern's edible parts include leaves and stems, which can be prepared in various ways—raw or cooked—and used in salads or as a vegetable side dish. Its introduction into Madeira highlights its adaptability beyond its native range. While not medicinal, the plant is of significant culinary importance to local communities due to its versatile use in traditional dishes.
