PLANT PROFILE
Xanthorrhoea species, commonly known as Grass Trees or Black Boy Tree, look excellent when used as striking focal points in native and xeriscape gardens. Their thick, woody trunks topped with dense tufts of grass-like foliage add a sculptural, architectural element that commands attention. The dramatic flower spikes, reaching up to 2 meters, attract nectar-feeding birds and insects, enhancing garden biodiversity.
These evergreen plants tolerate poor soils, drought, and fire, thriving in full sun with minimal maintenance once established. They are perfect for low-water gardens and rockeries. For added landscape impact, Grass Trees can be underplanted with low-growing native shrubs or succulents, creating a layered effect and varied texture that complements their bold form.
