Bursaria spinosa

Size: 40cm/45L
Sale price$300.00

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.

Please note, as living products, our trees naturally vary in size and appearance throughout the seasons.

For up-to-date sizing, please refer to our current height guide. If you’d like to see photos of our current stock, just let us know—we’re happy to send them!
