Asplenium oblongifolium

shining spleenwort

The shining spleenwort is a New Zealand endemic fern with glossy, dark green, once-divided fronds from 18 cm to 1 m long, growing from a stout rhizome. It grows on coastal cliffs and rock stacks and in lowland to montane forest, on the ground, on rocks or on trees. It is easy but slow to establish in cultivation and suits cool, shaded, humid conditions.

Where it grows wild

It occurs from coastal cliffs and rock stacks to deep forest, and is commonest in coastal and lowland areas. It grows on the ground, on rock, or as an epiphyte on trees. Plants on exposed coastal rock are tougher and more compact than those in forest shade.

It ranges from sea level to montane elevations, but is mostly coastal and lowland.
