Casuarina cones come from the Casuarina tree, which is a genus of evergreen trees and shrubs native to Australia, Southeast Asia, and other parts of the Pacific. The cones are the fruiting structures of the tree and are often called “she-oak cones” because the tree is also known as the she-oak.
Casuarina cones are small, woody, and cone-shaped. They contain small, winged seeds that are dispersed by the wind. The cones are typically found on the tree throughout the year, and can often be seen on the ground under the tree.
The Casuarina tree is widely cultivated for its fast-growing and hardy nature, and it is often used in reforestation and erosion control projects. The tree also has many uses in traditional medicine, as well as for its timber, which is valued for its strength and durability.
