Callistemon salignus, commonly known as Willow Bottlebrush, is an evergreen shrub or small tree native to the open woodlands and forest margins of Eastern Australia. It typically grows to 15 m (50 ft) in height, with a notable weeping habit resembling that of a willow. The foliage is soft, and the new growth emerges with a distinctive pink hue. The bark is white and papery, and the plant is known for its cylindrical spikes of white or creamy flowers that resemble a bottlebrush, which bloom in spring. These flowers are quite showy and are followed by woody capsules that contain the seeds.

Willow Bottlebrush is valued for its ornamental features, including its attractive bark and flowers, and its ability to attract birds with its nectar-rich blossoms. It is commonly used for screening and providing shelter due to its dense growth. It is also well-suited as a street tree or for planting in parks and gardens. While it can tolerate a range of soil types and moisture conditions, it is not frost-tolerant and should be protected from cold temperatures. In cultivation, it thrives in full sun and requires medium amounts of water, with best performance in soils with medium drainage. Care should be taken to avoid planting in areas with heavy frost, and it may require protection or suitable microclimate selection in cooler regions.CC BY-SA 4.0
