Frequently Asked Questions
No, it is not a true pine. While it is commonly called 'Australian pine', it belongs to a completely different family (Casuarinaceae) and its 'pine-like' appearance is due to convergent evolution.
They are native to Australia, Southeast Asia, and the Pacific Islands. They have been introduced to other tropical and subtropical coastal regions worldwide, such as Florida and the Mediterranean, for erosion control.
Its most distinctive feature is its drooping, jointed, needle-like branchlets (called cladodes) that look like long, green feathers or pine needles. The true leaves are reduced to tiny scales at the joints.
They are pioneer species that can grow in nutrient-poor, sandy soil. Their roots form a symbiotic relationship with bacteria that fix atmospheric nitrogen, thereby enriching the soil. This makes them valuable for reclaiming degraded land and stabilizing coastal dunes.
