A hardy and drought-tolerant evergreen tree, Eucalyptus microtheca, commonly known as the Coolibah Tree, is prized for its striking silvery-gray foliage, smooth, mottled bark, and ability to thrive in arid and semi-arid conditions. This fast-growing tree provides shade and beauty to desert landscapes and is well-suited for erosion control and windbreaks. Its resilience and adaptability make it a popular choice for low-water gardens and large spaces.
