albizia julibrissin silk tree

Features and Garden Uses

The albizia julibrissin silk tree is a fast-growing deciduous tree, reaching between 5–8 metres tall. During summer, its canopy is filled with sweetly scented, fluffy pink blooms, which attract bees, butterflies, and native birds. The soft, bipinnate leaves close at night, adding movement and interest to your landscape—perfect for informal garden designs, driveway borders, or as a dramatic centrepiece. This silk tree is often used to create dappled shade, and its airy growth makes it ideal for light, bright gardens. If you’re a fan of low-maintenance gardening, the albizia julibrissin silk tree is well-suited, requiring minimal pruning outside of initial shaping and tolerant of both heat and light frosts.
