Silver Tree Fern, Cyathea dealbata
The Silver Tree Fern (Cyathea dealbata), is a species of medium-sized tree fern, endemic to New Zealand.
This fern is known to grow to heights of 32 feet or more (though it occasionally takes a rare creeping form). The crown is dense, and the fronds tend to be about 13 feet long and have a silver-white coloration on the undersides. This distinctive silver coloration has made them useful for laying along tracks for night walking. The scales are a dark brown and are often twisted and glossy.
The Silver Fern occurs on the main islands of New Zealand east to the Chatham Islands, mostly in the sub canopy areas of drier forests and in open scrub. It is known to grow well in well-drained humus, and once established, it will tolerate drier conditions. It does best when sheltered from winds and should be protected from frost. It does not grow under the dense canopy of mature forests.
