The Golden Wreath Wattle tree (Acacia saligna) is another one of the Australian trees that are common in Southern Spain. Planted, in some cases along freeway medians and as a wind break this tree species can now be found growing wild in broad areas of Andalucia.
Although this tree is often quite scraggly with multiple stems it is a beautiful tree when in bloom. Its flowers are bright yellow little balls that grow along the ends of the new branches with the adult leaves interspersed (see image below).
The leaves are long and pointy becoming thinner and more pointy on the adult leaves. The juvenile leaves are broader and generally larger than their adult counterparts (the bottom picture is of new juvenile leaves).
