Cyathea Australis


Imagine the trunk of a Dicksonia combined with the fronds of a Cyathea. This pretty much sums up the Cyathea Australis. It is a curious fern with its main identifying feature being the slimness of the frond stems. Loads of these spring out from the centre of the trunk in all directions during the Summer. The fronds do tend to dry up easily around the edges though for some reason no matter where I try and place them. Not sure why yet?

This fern is supposed to be Winter hardy to -7c. I have not tested this yet, though I know they do remain undamaged at -4c. Some suppliers (usually online ones) tend to sell these as severed trunks. Try to avoid these as they will last that year and not recover for the next year. This applies to all Cyatheas and some Dicksonia species. Also, some Cyathea require the nutrients stored within exiting fronds to create new fronds.
Again frondless Cyathea will usually struggle to survive kicking out one or two fronds in the first year and then perishing due to starvation. Fortnately C. Australis doesn’t mind being frondless. However watch you don’t get conned !!!
