Acacia decurrens dealbata (Silver Acacia)

Acacia decurrens dealbata (Silver Acacia) is a fast-growing evergreen tree native to southeastern Australia. It belongs to the family Fabaceae and is a member of the genus Acacia.  The tree typically grows up to 30 meters in height, with a straight trunk and a dense, rounded crown.

The bark is smooth and grayish-brown in color. The leaves are feathery and bipinnate, with 4-10 pairs of pinnae, each bearing 10-30 pairs of leaflets that are 5-15 mm long and 0.5-1 mm wide. The leaves are a bright, silvery blue-green color, which gives the tree its common name. 

Silver Acacia produces fragrant, spherical, golden-yellow flowers in winter and early spring, which are held in tight, globular clusters at the ends of the branches. The flowers are followed by long, narrow, flattened seed pods that are up to 15 cm long. 

The tree is widely cultivated as an ornamental plant in many parts of the world, particularly in temperate regions. It is also grown for its wood, which is used for furniture, flooring, and pulp. In addition, the bark and leaves contain tannins and are used in the production of dyes and tanning agents.
