Casuarina equisetifolia

Casuarina equisetifolia: characteristics and care

The Casuarina equisetifolia, popularly known as casuarina or Australian pine, is an evergreen tree native to Australia, Southeast Asia and the Pacific Islands that stands out for its slender and elegant shape, with a light crown and feathery appearance similar to that of a horse’s tail, formed by articulated green branchlets that visually replace the leaves.

Its rapid growth and high tolerance to salinity and wind make it a highly valued choice for windbreaks and coastal screens, as well as for solitary specimens or rows in Mediterranean gardens. It tolerates drought well once established and adapts to poor, sandy soils, provided they have good drainage.

At Ornacom we cultivate each specimen directly, guaranteeing a balanced size and vigorous development from the first years of planting.
