Eucalyptus bicolor, commonly known as Black-Box, is an evergreen tree endemic to the floodplains and adjacent woodlands of southeastern Australia. It can reach up to 20 meters (66 ft) in height and is characterized by its rough, fibrous or flaky bark that extends to the smallest branches. The foliage consists of dull greenish-grey, lance-shaped leaves that provide a stark contrast to the white flowers when they bloom. The flower buds are oval to club-shaped and transition from green to yellow as they mature. Flowering is most prolific in autumn and spring, and the resulting fruit is hemispherical, cup-shaped, or barrel-shaped.

Black-Box trees are valued for their drought tolerance and ability to thrive in a variety of soil conditions, making them suitable for xeriscaping and as windbreaks in rural landscapes. They are also used for habitat restoration projects due to their ecological role in native floodplain environments. While they are not commonly used in small gardens due to their size, they can be a striking addition to larger landscapes. They require full sun exposure and can tolerate both low and medium water conditions, preferring soils with medium to fast drainage.CC BY-SA 4.0
