A wonderful, unique, and interesting plant the origins of Dicksonia antarctica go back tens of thousands of years. The dramatic look when this tree fern is in its full pomp is nothing short of magnificent. Find any shaded spot to grow a Dicksonia and you will never be disappointed. In their natural environment this tree fern grows under a forest canopy, so enjoys sheltered, shaded, moist environments. Dicksonia antarctica feed and drink from the top of the plant, just like it has a mouth! There is a hole at the top of the trunk which leads directly to the crown, or heart, of the tree fern. In their forest habitat, this hole fills with decaying leaf matter which has fallen from the canopy above. This helps the plant retain moisture, protects the crown of the tree fern from cold in winter and provides nutrient as the leaf matter decomposes. The nitrogen released by the decaying leaves is the food on which a Dicksonia antarctica thrives. The upper trunk is an exoskeleton made up of old frond bases and the lowest part of the trunk consists of a thread like substance which is used to anchor the plant to the ground. This is one of nature's true marvels and a 'must-have' for your garden. So glorious is this tree fern, the Royal Horticultural Society bestowed this plant with their Award of Garden Merit. A protected species, these Tree Ferns have been harvested under strict License, and the Australian government only allows so many to be exported each year, each one with its own permit and ID number. A tree fern takes around 10 years to grow 30cm, but even when bought as a dry 30cm log, once planted either in a border or a large pot, once the centre has been moist for a while, fronds of up to 1m in length will unfurl in the first year with you.
