Ornamental Features
Australian Tree Fern has attractive green foliage which emerges chartreuse in spring. The large ferny bipinnately compound leaves are highly ornamental and remain green throughout the winter. Neither the flowers nor the fruit are ornamentally significant. The rough brown bark adds an interesting dimension to the landscape.

Planting and Growing
Australian Tree Fern will grow to be about 20 feet tall at maturity, with a spread of 12 feet. It has a high canopy of foliage that sits well above the ground, and is suitable for planting under power lines. As it matures, the lower branches of this tree can be strategically removed to create a high enough canopy to support unobstructed human traffic underneath. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 30 years.
This tree does best in full sun to partial shade. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil pH, but grows best in rich soils. It is somewhat tolerant of urban pollution. Consider applying a thick mulch around the root zone in both summer and winter to conserve soil moisture and protect it in exposed locations or colder microclimates. This species is not originally from North America.
Australian Tree Fern is a fine choice for the yard, but it is also a good selection for planting in outdoor pots and containers. Because of its height, it is often used as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. It is even sizeable enough that it can be grown alone in a suitable container. Note that when grown in a container, it may not perform exactly as indicated on the tag - this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
