About

She-Oaks — the genus Casuarina and its close Australian relative Allocasuarina — are among the most distinctive and ecologically important native trees in the Australian landscape. Despite their common name, She-Oaks are not true oaks: the name comes from the attractive, ray-patterned timber that resembles European oak, but weaker. They are not even closely related to oaks. What they are is uniquely Australian: trees and shrubs that have evolved extraordinary adaptations to thrive in the continent's harshest conditions — coastal sand dunes, rocky ridgelines, dry inland plains, and exposed windy headlands — where most other trees would fail. The most striking visual feature of Casuarina and Allocasuarina is the foliage. What appear to be needle-like leaves are actually jointed, photosynthetic branchlets — the true leaves have been reduced to tiny scales along the branchlet joints. This adaptation reduces water loss to an absolute minimum, which is why She-Oaks handle drought, coastal salt spray, and exposed wind conditions with a composure that few other native trees match. The result is an airy, soft texture — somewhere between a conifer and a weeping willow — that creates a distinctive visual effect utterly unlike any other Australian native. Our collection spans seven varieties covering an extraordinary range of garden and landscape applications — from the extraordinary Cousin It groundcover (one of the most conversation-starting plants in any garden) to the towering River She-Oak for large-scale screens and windbreaks, and the ornamental Rose She-Oak with its rusty bronze flowering display. Each variety has been selected by our horticultural team for proven performance and clear garden utility in Australian conditions. An important note on Casuarina vs Allocasuarina You will notice that some plants in this collection are labelled Casuarina and others Allocasuarina. This reflects a taxonomic revision made in the 1980s that split the original Casuarina genus — all
