"Norfolk Island Tree Fern"
This is regarded as the largest of all treeferns, though in cultivation its dimensions may be exceeded by other species such as C. medullaris, particularly in a cooler climate. A very robust, beautiful species, closely related to C. cooperi but far more spectacular in size and appearnace. It is not very common in cultivation outside of Australia. The fronds can reach up to 20' long and are held in a most attactive habit, and the trunk, which is quite thick under humid conditions, can in the wild reach an incredible height of 100'! As the fern ages, the trunk appears to look more woody and may also show some taper.
