Acacia cognata, commonly known as Narrow-Leaf Bower Wattle, is an evergreen shrub or small tree native to the open woodlands and forest margins of Southwestern Australia. It exhibits a variable habit, typically ranging from 0.6 to 10 meters (2 feet to 32 feet 10 inches) in height, with an erect to spreading form. The bark on the trunk and larger branches is smooth and colored in shades of grey to grey-brown. Its foliage consists of narrow, pendulous leaves that contribute to its graceful appearance. The pale yellow, globular flower heads are small, about 3 to 6 mm (0.12 to 0.24 inches) in diameter, and contain 10 to 25 individual flowers. These blooms appear singly or in pairs in the leaf axils and are most prolific from July to October in its native habitat, offering subtle ornamental value.

Narrow-Leaf Bower Wattle is appreciated for its weeping foliage and textural interest in the landscape. It is often used in ornamental plantings, urban gardens, and as a feature or screen plant. This species is drought-tolerant once established, making it suitable for low-water landscapes. It thrives in full sun and requires well-drained soils, preferably with a neutral to slightly acidic pH. While generally low-maintenance, it can be susceptible to root rot in poorly drained conditions and may be affected by pests such as aphids or borers. Pruning can be done to maintain shape and encourage denser growth.CC BY-SA 4.0
