Eucalyptus largiflorens, commonly known as Black Box, is a slow-growing, evergreen tree endemic to Australia, specifically adapted to grassy woodlands and floodplain ecosystems within the Murray-Darling basin across Queensland, New South Wales, Victoria, and South Australia. It typically reaches up to 66 feet (20 meters) in height and is characterized by its rough, fibrous bark and dense canopy of lance-shaped, dull green leaves. The tree is notable for its white flowers that appear mainly in autumn and spring, attracting a variety of pollinators, and its hemispherical fruit that follows the flowering period.

Black Box trees are valued for their drought tolerance and ability to withstand temporary flooding, making them suitable for cultivation in areas with similar challenging conditions. They are often used in reforestation projects and as windbreaks in rural landscapes. In gardens, they provide dense shade and habitat for wildlife. While they prefer full sun, they can tolerate a range of soil types, provided they are well-drained. Care should be taken when planting near structures or plumbing, as their roots can be invasive.CC BY-SA 4.0
