Report an issue with this species

Casuarina species are fast-growing evergreen trees with slender, pendulous branches resembling pine needles and a weeping canopy. They produce cone-like fruits and are highly tolerant of various soil conditions and salty coastal winds, making them suitable for windbreaks and erosion control. However, some species are considered weedy and can aggressively outcompete other plants.
