Name - Dicksonia squarrosa otherwise known as brown tree fern or Wheki (Maori), is one of New Zealand's national tree ferns.
The word Dicksonia is taken from James Dickson, a Scottish botanist (1738-1822).
Care Tips - As a general rule ferns thrive well in a cool, bright lit area and in high humidity, with a minimum temperature of 10ºC/50ºF. They also need frequent watering and plenty of light, but should be kept away from direct sunlight and draughts.

In the wild it inhabits moist mountain areas in Victoria, New South Wales, and Queensland, and is often found growing in the company of Dicksonia antarctica but preferring more sunny open spots.

In the colder parts of Ireland winter protection of the trunk is recommended and as with all Tree Ferns the crown should be filled with straw, leaves or as in my case pine needles.
