Acacia siculiformis, commonly known as Dagger Wattle, is an evergreen shrub native to the dry sclerophyll forests and woodland areas of Southeastern Australia. It typically grows to a height of 2 to 3 meters (6.6 to 9.8 ft) and can exhibit a procumbent habit, meaning it sometimes grows flat along the ground. Dagger Wattle is characterized by its glabrous (smooth and hairless) foliage and its distinctive flowering season from August to November. The inflorescences are simple, occurring singly or in pairs in the axils, and are followed by the production of straight, flat, papery seed pods measuring 1.5 to 5 cm (0.59 to 1.97 in) in length and 4 to 7.5 mm (0.16 to 0.30 in) wide, with fine lateral veins near the margins.

Dagger Wattle is valued for its hardiness and low maintenance requirements, making it suitable for xeriscaping and as an ornamental plant in gardens that experience dry conditions. It thrives in full sun and is adaptable to a range of soil types, provided they offer medium to fast drainage. While it requires low to medium amounts of water, it can tolerate drought once established. This species is not commonly known for aggressive roots or significant disease problems, but like many Acacias, it may be susceptible to root rot in poorly drained soils.CC BY-SA 4.0
