Allocasuarina torulosa is a medium to tall tree, with a straight trunk and a narrow to spreading crown. It has dark, deeply fissured bark and graceful, drooping, needle-like branchlets with rich dark green to grey-green foliage, giving the tree a soft, weeping appearance. The true leaves are reduced to tiny teeth arranged in whorls along the branchlets. Small, woody cones develop after flowering and contain winged seeds that provide an important food source for seed-eating birds
Allocasuarina torulosa is native to eastern Australia, where it occurs in open forests and woodlands along coastal areas and mountain ranges. It is commonly found on well-drained soils derived from sandstone or shale and frequently grows in association with eucalypt forests. The species is adaptable to a wide range of soil types and conditions, showing good tolerance to drought, moderate frost, and urban environments, which makes it well suited to parks, streetscapes, and large gardens.
