Acacia melanoxylon is more commonly known as Australian blackwood. Other names include Blackwood, Blackwood acacia, and Tasmanian lightwood.
This tree is native to Australia, where it mostly grows along the southern and eastern coast. It has become natutralised to Africa, Brazil, and New Zealand.
It usually grows to a height of about 65 feet (20 m), but its size and shape can be pretty variable.

In its native environment, Acacia melanoxylon has small blooms from July to December.
The growing of Acacia melanoxylon requires a lot of space due to its large size.
A large specimen can grow up to 80 feet (25 m) tall and have a sprawl as wide as 40 feet (12 m).
Because of the size of this tree, it should not be planted near sidewalks, pavement, or underground plumbing.
Full sun is required. This plant is not frost resistant so this tropical plant should only be grown in the warmer USDA zones, nine through eleven.

Well-drained soil with medium moisture tends to give the best results.
In proper conditions, the tree will grow quickly so be sure that it is directly planted somewhere that can accommodate a large tree instead of transplanting it at a later date.
Acacia melanoxylon is typically disease-free but may attract pesty weevils. It can help to attract avian pollinators to the area.
