Native primarily to Australia; Casuarina equisetifolia is also a Pacific Island native. Long, thin, jointed, green branches look like long pine needles; true leaves are inconspicuous. Tolerate many tough conditions: dry or wet soil, salinity, heat, wind. Hardy to 15°F/–9°C. Particularly useful in desert areas, where they are often confused with Athel tamarisk (Tamarix aphylla) because of similar foliage—but the casuarinas have conelike fruit. Cones range from 1/4 to 1 in. long in species described here; those of Casuarina stricta are largest. Little pruning required.Casuarina cunninghamiana
