Cyathea is a genus of tree ferns, the type genus of the fern order Cyatheales. They are mostly terrestrial ferns, usually with a single tall stem. Rarely, the trunk may be branched or creeping. Many species also develop a fibrous mass of roots at the base of the trunk. The genus has a pantropical distribution, with 230-240 species. They grow in habitats ranging from tropical rain forests to temperate woodlands. Tree Fern refers to any fern that grows with a trunk elevating the fronds above ground level. ...

Although Cyathea cooperi has been overwintered successfully in England and other cool climates, I do not generally tend to recommend it to gardeners in such locations unless they really want it for their collection, or it is the only species they can get hold of.
It is, in fact, the least hardy species of Cyathea to which I have given a sub-page of its own (and I've done this only because it is such a well-known species).
