Origin and invasive character

Most varieties are native to Australia and Tasmania, up to 1000 m s. no. m..

In other parts of the world it has behaved like an invasive species. In Spain, due to its colonizing potential and constituting a serious threat to native species, habitats or ecosystems, this species has been included in the Spanish Catalog of Invasive Alien Species, regulated by Royal Decree 630/2013, of 2 August, being prohibited in Spain, except the Canary Islands and the Balearic Islands, their introduction into the natural environment, possession, transport, traffic and trade.

Subspecies

There are two subspecies:

• Acacia dealbata dealbata. Low to moderate altitudes. Trees up to 30 m; leaves mostly 5-12 cm long.
• Acacia dealbata subalpina Tindale & Kodela. High altitudes in Snowy Mountains. Bust up to 5 m (rarely 10 m) tall; leaves mainly between 1.5 and 8.5 cm long.

Uses

Planted in parks, streets, walks, although the most widespread use is gardening due to the color of its flowers and the number of them, offering sets of great beauty. It is cultivated as a soil fixer and for the gum that is obtained from its tannin-containing trunk.

Chemical products, fodder, domestic uses, environmental management, fiber, food, beverages, and wood are obtained.

In Italy the symbol of women's day is the mimosa, and it is customary to give a small bouquet of mimosa to women. In some jobs they give all the employees a bouquet, or a sweet called "mimosa", many bakeries prepare the yellow sweets (remembering the color of the mimosa) and in the streets there are many mimosa vendors.

Acacia dealbata was described by Johann Heinrich Friedrich Link and published in Enumeratio Plantarum Horti Regii Berolinensis Altera 2: 445. 1822.
