Celtis australis, commonly known as the European Hackberry, Mediterranean Hackberry, or Nettle Tree, is a medium to large deciduous tree native to Southern Europe and parts of Western Asia. It is highly valued for its hardiness, tolerance to urban pollution and drought, and its broad, arching canopy that provides excellent shade.

This species features smooth grey bark, serrated, ovate leaves, and produces small, sweet, dark purple fruits that are attractive to birds. Its elegant form and environmental resilience make it a preferred choice for urban landscaping, avenue planting, and ecological restoration.
