Cyathea dealbata, also known as the silver tree fern or silver fern is a species of medium-sized tree ferns, endemic and symbolic to New Zealand. It can grow to heights of 10 m or more with a dense crown of long (4m) fronds that have a silver-white colouration on the undersides. This distinctive silver colouration has made them useful for laying along tracks for night walking. Once established, it will tolerate drier conditions but it does best when sheltered from strong winds and frost in a well drained shady damp position. For the UK it needs to be kept pot grown (which will also contain its ultimate size) and brought under cover for winter, unless in a very mild sheltered microclimate..
