Native primarily to Australia. At first glance, these look something like pines; their thin, jointed, green branches look like long pine needles. True leaves are inconspicuous. These trees tolerate dry or wet soil, salinity, heat, and wind, and they’re hardy to 15°F (–9°C). Especially 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 1/4–1 in. long. Little pruning is required.Casuarina cunninghamiana
