Once a popular basket and rockery plant because of its ability to withstand low light and neglect, this plant is naturalised throughout a large proportion of the NSW coast.

  • Origin North Eastern Australia
  • Habit Terrestrial fern that forms dense clumps of upright, arching fronds that resemble fish bones with erect rhizome and slender stolons.
  • Leaves Compound fronds with opposite or alternate leaflets, often over lapping at base, to 1m. Leaflets to 6cm long.
  • Flowers Nil.
  • Fruit Spores carried in round, brown clusters (sori) that form in two rows on underside of frond.
  • Roots Erect, branching rhizomes above or below ground level, with wiry stolons bearing rounded, hairy tubers.
  • Dispersal Spores carried by water, wind and contaminated soil (tyres, earth works, people‚Äôs shoes, green waste dumping). Problematic in any damp, shady areas, where it will completely dominate ground cover layer.
