Dicksonia antarctica Tree fern Evergreen fern (1 Page of 5) The Dicksonia antarctica plant species is found in Australia - New South Wales, Tasmania, Victoria. It is a member of the Dicksoniaceae family. Common gardeners may know the plant as Tree fern. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Dicksonia antarctica Common Name: Tree fern Family: Dicksoniaceae Author: Labill. Known Hazards: Although we have found no reports of toxicity for this species, a number of ferns contain carcinogens so some caution is advisable[200].
Many ferns also contain thiaminase, an enzyme that robs the body of its vitamin B complex. In small quantities this enzyme will do no harm to people eating an adequate diet that is rich in vitamin B, though large quantities can cause severe health problems. The enzyme is destroyed by heat or thorough drying, so cooking the plant will remove the thiaminase[172]. Mature Height: 9 Mature Width: 4 Habitat: Damp sheltered woodland slopes and moist gullies[144].
Edible Uses: The pith in the upper part of the trunk just below the growing point is eaten raw or roasted[46, 61, 154, 193]. It is rich in starch[105, 144] but also contains tannin and is astringent[154]. Descriptions of the taste vary from bitter to sweet, astringent and like a bad turnip[193]. The core of the plant near the growing tip is used[193]. Harvesting the stem kills the plant so this use cannot normally be condoned[193]. The stem contains about 61 kilocalories per 100g[193].
Young leaves - cooked. Harvested just before they unfurl, they are juicy and slimy, tasting like bitter celery[193].
