The Silver Wattle or Mimosa (Acacia dealbata)is native to some parts of southeastern Australia. In some countries, the mimosa is the symbol of celebration of International Women’s Day (on March 8 every year). In countries such as Albania, Georgia, Italy, and Russia, women are presented with the flowers of this plant on the occasion.

Acacia dealbata is a fast growing evergreen ornamental tree that can grow up to a height of 30 meters. The trees have mostly blue-green bi-pinnate leaves. They bloom in large bright yellow inflorescences made up of numerous smaller globular flower heads of 13 to 42 small individual flowers.

The flowers are harvested and sold as cut flowers (mimosa flowers) by florists. The essence of mimosa flowers can be extracted and used to make excellent perfumes.

The timber of the silver wattle looks similar to Blackwood and has honey color. Its timber is used for indoor woodwork and to make furniture and often used for building temporary wooden structures and low-cost dwelling units like huts.

These trees have been introduced and naturalized in Albania, Chile, southwestern China, Georgia, Italy, New Zealand, Norfolk Island, Russia, the United Sates (California), as well as some areas around the Mediterranean.

The Acacia dealbata, mostly cultivated as ornamental plants or garden trees and for shade, are best suited for warm temperate regions. They cannot survive in very cold regions as they do not survive in prolonged frosts.
