|I took this photo whilst visiting Wittunga Botanical Gardens with a friend. It is of an Acacia tree in flower. These would have to be one of my favourite Australian natives, the blossom is glorious!!|
ACACIA: is a genus of around 1200 species, 954 of which are currently recognised as occurring in Australia. The next largest occurrence is in Africa. The plants occur in all Australian states from coastal zones to mountains to the dry inland. Collectively the Australian species are known as "wattles" and one of them, Acacia pycnantha, is the national floral emblem. The green and gold colours of the foliage and flowers has provided Australia's official colours.
The derivation of the term "wattle" for Australian Acacias is interesting. "Wattle" is an old English word meaning interlaced rods and twigs. In the early years of the European settlement in Australia, shelters were constructed of flexible sticks woven together and plastered with mud, a technique known as "wattle and daub" and the wood most commonly used came from a plant now called Callicoma serratifolia which became known as "Black wattle". Callicoma has Acacia-like flowers but is not closely related to Acacia. However, because of the similarity in flowers, the term "wattle" eventually became associated with all Australian acacias and, even more confusingly, "Black wattle" is also applied to some Acacia species.
Australian acacias are generally small to large shrubs but there are a few which become large trees. The individual flowers are very small but are arranged into rod-like or globular heads of a large number of flowers. The colour is almost invariably in the range between white and bright yellow but one solitary species (A.purpureapetala) has mauve flowers and a recently discovered form of the normally yellow-flowered Acacia leprosa has deep pink flowers. This form has been given the cultivar name "Scarlet Blaze"
Many Australians regard the flowering of wattles as signalling the coming of spring and it's true that many commonly grown species flower in late winter. However, it's equally true that a wattle can be found in flower somewhere at any time of the year. Following flowering, seeds develop in pods (legumes) which vary in shape between species and may be flat, short, elongated or cylindrical.
Many Acacia species occur in areas where bushfires are common, such as dry forests and woodlands. In these habitats they are often "pioneer" species, quickly recolonizing burnt-out areas and then being gradually replaced by other species in the plant community. They are often helped in this role by ants which store the seeds underground. The seeds themselves usually have a very long viability.

These flowers are just so attractive. It is a stunning tree, and grows in NZ too - it's not a native tree here though!
Well shown Tina, and TFS,
