About Xanthorrhoea quadrangulata F.Muell.
Xanthorrhoea quadrangulata F.Muell. is a very slow growing plant with a thick, rough trunk and blue-green foliage. In the wild, its trunk is often burnt black by wildfires. Trunks can reach 2 meters or more in length, and are frequently branched. As is typical for trunked Xanthorrhoea species, this species grows extremely slowly, increasing in height by an average of only 2–3 cm per year. Flowering occurs irregularly from winter to spring, producing flower spikes between 1 and 3 meters tall. These spikes hold small, nectar-rich flowers that serve as a food source for nectar-eating birds and butterflies. This plant is distributed broadly across the Mount Lofty Ranges, and its range extends into the Flinders Ranges. It often grows on rocky sites and ridges, and shows particular tolerance for clay soil.
