Acacia lasiocalyx, commonly known as Silver Wattle or Shaggy Wattle, is a deciduous shrub or small tree from the genus Acacia within the subgenus Juliflorae. It is native to arid and semi-arid regions, particularly in rocky or sandy soils of Western Australia. Silver Wattle typically grows to a height of 1.5 to 7 meters (5 to 23 ft), with some specimens reaching up to 25 meters in their natural habitat. The plant has a weeping habit with a sparse, open canopy. It produces bright yellow, rod-shaped flower clusters from July to October, which are highly attractive to pollinators. The linear seed pods that follow are distinctive, raised over the seeds, and can be up to 16 centimeters (6.3 in) long.

Silver Wattle is valued for its drought tolerance and ability to thrive in full sun with minimal water requirements, making it suitable for xeriscaping and as an ornamental in dry gardens. Its fast-draining soil preference and low water needs contribute to its ease of maintenance. The plant’s weeping form and vibrant yellow flowers make it a striking addition to landscapes. However, it can be prone to root rot if overwatered or planted in poorly drained soils. In regions outside its native range, care should be taken as it can become invasive.CC BY-SA 4.0
