About Your New Bursaria spinosa

Bursaria spinosa, commonly known as Australian Blackthorn or Sweet Bursaria, is a hardy native shrub or small tree with dense, thorny branches ideal for natural hedging and habitat planting. Masses of fragrant white flowers bloom from late spring through summer, drawing in pollinators and butterflies, including the Eltham Copper butterfly.

Its fine, green foliage and upright, irregular form create both visual interest and protective structure. Looks excellent when planted as a low-maintenance wildlife hedge or used to frame native gardens with a naturalistic, textured edge.
