Cyathea cooperi (Australian Tree Fern) - This is a fast growing tree fern that grows to 20 feet and spreads up to about 8 to 12 feet. The finely divided fronds rise out of the trunk and arch down as they get older. Fuzzy brown and white scales cover the trunk and leaf stems. Plant in bright light (even tolerates full sun in coastal areas) in a well-drained soil and provide regular irrigation. Irrigation can be applied to the trunk as well as the surrounding soil but avoid watering the crown as this enhances conditions that promote diseases such as Rhizoctonia or Tip Blight (Phyllosticta). Tip blight has become a more prevalent disease of tree ferns in southern California and seriously disfigures the new growth and older foliage. Given optimum conditions this plant can grow several feet per year and reach 20 feet tall. It is hardy to about 20 degrees F.  This description is based on research and observations made of this plant as it grows in our nursery, in our nursery garden and in other gardens that we have visited. We also try to incorporate comments received from others and appreciate getting feedback of any kind from those who have any additional information about this plant, particularly if they disagree with what we have written or if they have additional cultural tips that would aid others in growing Cyathea cooperi.
