The black tree fern, scientifically known as Cyathea medullaris, is a large, evergreen fern species belonging to the family Cyatheaceae. It is native to New Zealand and is also commonly found in parts of Australia, particularly in the eastern coastal regions.
The black tree fern is characterized by its tall and striking appearance, with a trunk that can grow up to 20 meters (65 feet) in height. The trunk is covered in a dark brown to black, fibrous material, hence its common name "black" tree fern. This fibrous covering, known as "pulaka," is made up of dead fronds and serves to protect the trunk from external elements.
The fronds of the black tree fern are large and feathery, reaching lengths of up to 5 meters (16 feet) and forming an attractive, airy canopy. The fronds are dark green in color with a glossy appearance, contrasting beautifully with the black trunk. This fern is a popular ornamental plant in gardens and landscapes due to its unique and visually striking aesthetic.
In its natural habitat, the black tree fern thrives in moist, shaded areas such as forests and gorges. It requires well-drained soil and moderate rainfall for optimal growth. The fern reproduces through spores, which are released from the undersides of mature fronds.
Overall, the black tree fern is a magnificent and decorative plant known for its towering height, striking black trunk, and large, elegant fronds.
