Allocasuarina littoralis
Black Sheoak
The Allocasuarina littoralis, or Black Sheoak, is a medium-sized evergreen tree native to Australia, valued for its fine, needle-like foliage and adaptability. Growing up to 8–15 meters, it features dark, furrowed bark and a graceful, upright form. Its foliage, made up of thin, jointed branchlets, creates a soft, wispy appearance. In winter and spring, it produces small, red male flowers and woody cones that add seasonal interest.
This hardy and drought-tolerant tree thrives in challenging environments, making it ideal for windbreaks, erosion control, and native gardens.
