Mimosa

Acacia dealbata (cây keo bạc) (Silver Wattle) is a species of Acacia, native to southeastern Australia in New South Wales, Victoria, Tasmania, and the Australian Capital Territory.^[1]
It is a fast growing evergreen tree or shrub growing up to 30 m tall, typically a pioneer species after fire. Trees generally do not live longer than 30 to 40 years, after which in the wild they are succeeded by other species where bushfires are excluded. In moist mountain areas, a white lichen can almost cover the bark, which may contribute to the descriptor "silver". In pure stands this creates a similar effect to a birch woodland and can be quite striking when discovered on foot.
The flowers and tip shoots are harvested for use as cut flowers, when it is known by florist trade as "mimosa". In Italy and Russia the flowers are also frequently given to women on International Women's Day.
