Tree Fern Pictures

New Zealand ponga fern plants


The tree fern pictures below show a selection of the amazing diversity of native tree ferns in New Zealand.

Tree ferns plants grow in a variety of habitats, although most are found in damp shady sites beneath tree canopies, growing in well drained rich loamy soils up the sides of gullies in New Zealand native bush.

Nearly all New Zealand tree ferns require shade and shelter. Exceptions include the black ponga (Cyathea medullaris) which will tolerate a more open sunny site and the fast-growing wheki tree fern (Dicksonia squarrosa) which can stand some wind and sun if soils are reliably moist. A minimum winter temperature of -2°c is advised for growing New Zealand tree fern species.

The New Zealand silver fern is especially well-known as New Zealand's emblem. The silver fern leaf underside is most striking.
