Common Ground Fern
Calochlaena dubia
Calochlaena dubia, commonly known as soft bracken, false bracken, common ground fern or rainbow fern, is a small Australian fern in the treefern family Dicksoniaceae. It is very common within its range, and often seen growing under eucalyptus forest, often on the poorer quality soils. It is an easy plant to grow in the garden.

Description
The fronds arise from the thick brown haired rhizomes and are anywhere from 0.4 to 1.5 m in height. The foliage is a more yellow green colour, in contrast to the darker shiny green of bracken (Pteridium esculentum). The stipe changes from dark brown, through reddish- to yellow brown, and is covered with soft brown hairs. The fronds are triangular overall and tripinnate-pinnatifid in shape. The sori occur near the margin.
Range & habitat
Calochlaena dubia is found as an understory plant in open forests and rainforests in eastern Australia, from Queensland, through New South Wales and Victoria into Tasmania. It can form large banks or swathes.

How it is grown
Well suited to the garden, Calochlaena dubia is an easy plant to grow. In fact, it must be kept in check by cutting the rhizomes and given plenty of room. It does well on clay soils.
