Fast-growing evergreen tree or large shrub to 20-30’ tall and wide. This tough yet very attractive Australian native features gracefully weeping branches clothed with dense, narrow, billowing bright-green foliage that makes this durable species a visual standout in the landscape. Abundant, lightly-fragrant, powder-puff-like creamy-yellow flowers appear near the branch tips late-winter into spring, followed by small, bean-like seed pods that eventually mature to light-brown. With its beautiful weeping appearance, this selection is impressive in most any setting, but is especially well-suited as a bushy accent or background, as a patio, courtyard or entryway tree, or as an attractive large container specimen. Prefers a well-drained soil and while capable of surviving with little water once established, a more robust specimen is achieved with moderate watering. Tolerates coastal conditions where it can thrive in a full sun exposure, but prefers filtered sun to light shade in warmer inland climates.

USDA Zone: 9A-11
