A well-grown tree fern is a fast-growing plant, and will likely outgrow its space within a few years. The trunk of the Australian tree fern starts out as a low, wide clump and spreads as much as six feet in a year before growing upward into a single slender trunk covered in glossy ginger-brown hairs.
Fronds on mature specimens may reach 2m (6ft) or more in length. They should be planted in humus-rich, neutral to slightly acid soil. Extremely slow-growing, these desirable plants only increase by about 2.5cm (1in) a year.
