Tree Fern: Tasmanian or Soft Tree Fern Dicksonia antarctica
FAMILY: DICKSONIACEAE (Ferns)
Tasmanian tree ferns Dicksonia antarctica, like other tree ferns, are survivors from the fossil age and don't grow naturally anywhere but the Southern Hemisphere. Also known as the soft tree fern, this Australian species is found in moist, shady areas called fern gullies from northern Queensland to Tasmania. Amazingly, old, well-established plants can reach heights of almost 50 feet (15 meters), with massive trunks covered in furry brown roots.
