Dicksonia antarctica

These ferns can grow several metres over many decades. They are very hairy at the base of the stipe (trunk). It has large, dark green, dramatic fronds that spread in a canopy of 2–6 metres in diameter. The shapes of the stems vary as some grow curved and there are multi-headed ones. D. antarctica is an evergreen tree fern, but deciduous in colder areas such as Ireland, where new fronds grow out again after winter.
