Sphaeropteris cooperi is a medium-to-large fast growing tree fern, to 15 metres (49 ft) in height with a 12-inch (30 cm) thick trunk.

The apex of the trunk and unfurling crosiers are particularly attractive, covered as they are with conspicuous long, silky, straw colored scales.

The crown is widely spread and the light green fronds may reach a length of 4–6 metres (13–20 ft).

[citation needed] Sphaeropteris cooperi is one of the most commonly cultivated tree ferns as an ornamental plant.

It has also naturalized in New Zealand, South Africa, Tanzania, the Mascarene Islands, the Azores, Madeira and Hawaii, where it is classified as an invasive species.
