Description
Casuarina (often Casuarina equisetifolia, known locally and used widely in Thailand) is a striking evergreen tree native to coastal areas in Southeast Asia. In Bangkok, it’s frequently sculpted into elegant topiary forms—such as tiered spheres or spirals—creating living sculptures that blend artistic flair with natural appeal. The tree’s needle-like branchlets resemble soft foliage, giving the forms a refined texture without being overly dense .
Beyond aesthetics, Casuarina topiary serves important practical functions. Its extensive root system stabilizes soil and prevents erosion, especially useful in urban landscapes and park settings . These trees tolerate full sun, well-drained or sandy soils, and even salty coastal air. Once established, they require minimal water, are drought-tolerant, and need only occasional pruning to retain their shaped form.
