False Bracken

False bracken is truly not bracken… it is a fern.

  • False bracken is a species of common fern, native to eastern forest areas of Australia.
  • ‘False brackens’ are also known as ‘rainbow ferns’, ‘soft brackens’ and ‘common ground ferns’.
  • The scientific name of false bracken is Calochlaena dubia, though it was previously listed as Culcita dubia, and it is from the family Dicksoniaceae, a family of various ferns.
  • False bracken leaves, or ‘fronds’ as they are known, reach a length of 0.4 to 1.5 metres (1.3 to 4.9 feet), and they tend to droop at the ends.
  • The false bracken scientific genus name ‘Calochlaena’ is said to come from Ancient Greek, meaning ‘beautiful cloak’, while ‘dubia’, or ‘dubious’ in English, is a Latin term and has the meaning ‘doubtful’.

  • The leaves of false bracken are lacy and range from green to yellow-green in colour, and are hairy and quite soft to touch.
  • False bracken plants do not produce flowers, and instead reproduce through the use of spores that grown on the underside of the leaves.
  • The false bracken plant grows from a rhizome, that spreads underground and can be divided to produce more plants, and the rhizomes are covered in brown hairs.
  • False brackens grow as understory plants that are easily cared for, and as such, are useful as a garden plant.
  • False bracken plants grow to heights from 50 cm to 2 metres (1.6 to 6.6 feet) and prefer well-drained soils that are moist, and partly shady conditions.
