A large evergreen banyan-type fig tree from eastern Australia, best known for massive buttress roots and a strangler habit that starts as an epiphyte on a host tree. It is grown mainly in large parks and gardens in frost-free or lightly frosted climates, as its huge size suits only big sites.

About
Ficus macrophylla, commonly known as the Moreton Bay fig or Australian banyan, is a large evergreen banyan tree of the mulberry and fig family Moraceae. It is native to eastern Australia, from the Wide Bay–Burnett region of Queensland in the north to the Illawarra region of New South Wales. The infraspecies Ficus macrophylla f. columnaris is endemic to Lord Howe Island. Its common name refers to Moreton Bay in Queensland. It is best known for its imposing buttress roots.
Ficus macrophylla is called a strangler fig because seed germination usually takes place in the canopy of a host tree, where the seedling lives as an epiphyte until its roots establish contact with the ground, when it enlarges and strangles its host, eventually becoming a freestanding tree by itself. Individuals may reach 60 m (200 ft) in height. The greatest exact height to be reported is 70.6 m (232 ft).
How to grow it
The Moreton Bay fig has been widely used in public parks in frost-free areas, and was popular with early settlers of Australia. Around the beginning of the 20th century, the director of the Royal Botanic Gardens in Sydney, Joseph Maiden, advocated the planting of street trees, generally uniform rows of the one species. He recommended Moreton Bay figs be spaced at 30 m (100 ft) intervals—far enough to avoid crowding as the trees matured, but close enough so that their branches would eventually interlock. Specimens can reach massive proportions, and have thrived in drier climates; impressive specimen trees have been grown in the Waring Gardens in Deniliquin, and Hay. They can withstand light frosts and can cope with salt-laden spray in coastal situations, and their fruit is beneficial for urban wildlife. However, their huge size precludes use in all but the largest gardens, and their roots are highly invasive and can damage piping and disrupt footpaths and roadways; the vast quantities of crushed fruit can be messy on the ground.
Where it grows
The Moreton Bay fig is a native of eastern coastal Australia, from the Wide Bay–Burnett region in central Queensland, to the Shoalhaven River on the New South Wales south coast. It is found in subtropical, warm temperate, and dry rainforest, where, as an emergent tree, its crown may tower above the canopy, particularly along watercourses on alluvial soils. In the Sydney region, F. macrophylla grows from sea level to 300 metres (980 feet) altitude, in areas with an average yearly rainfall of 1,200–1,800 mm (47–71 in).
Uses
The soft light timber has a wavy texture and is used for cases. Aboriginal people traditionally use the fibres for fishing nets. The fruits are edible and taste like other fig varieties.
