Cyathea cooperi

Cyatheas are the tallest of the ferns and can provide a microclimate for other ferns and moisture loving plants in the garden.

Their lacy bright green fronds add a tropical feel and the architectural crosiers provide a long-lasting focus as they unfurl.

They grow best in high humidity and high soil moisture conditions so planting them in a protected area is a good idea. Regular applications of mulch will help keep the soil moist and also provide nutrients to the shallow root system. Treeferns usually respond well to organic fertilizers and well-rotted animal manures.

Because of their weed potential, care should be taken to avoid planting this species near moist bushland areas.

Aboriginal people split the trunk and ate the starchy pith raw or roasted. In many areas the unopened fronds were roasted to remove the shikimic acid - then eaten.
