Cyathea cooperi is commonly known as Australian tree fern, lacy tree fern, scaly tree fern or Cooper’s tree fern. Among leptosporangiate ferns (the class Polypodiopsida or Pteridopsida, whose spores originate from a single epidermal cell–most ferns), the tree ferns form their own order, the Cyatheales. In other words, the tree ferns form a distinct group, though not all members of the group have the trunk-like stem.
The plant in the photograph is likely young at perhaps a metre tall, as Cyathera cooperi can grow up to 30cm/a (12in/year), with a maximum height range of 10 to 15m, depending on what reference one reads. Ideal conditions for Cyathea cooperi include shade, protection from wind, little if any frost temperatures, and moist organic soils. Native to parts of eastern Australia, Cyathea cooperi has naturalized in other areas of Australia outside its range, as well as become an invasive species in Hawai’i and other Pacific Island ecosystems.
