Why Mimosa is a symbol in this day?

According to the legend there was a tree of Mimosa near to the industry.

But the real reason of this choice is the low cost of this flowers and its bloom that is until March.

Italian women have chosen Mimosa as "women's plant" : every year is usual give one to every grandmother, aunt, daughter or mother. In short, every women has a Mimosa in the Women's day.

 Shortly after he was held an International Conference of Socialist Women, attended by 58 delegates from 13 countries, in which it was decided the creation of an Information Office of Socialist Women: Clara Zetkin was elected secretary and the magazine from her prepared became the organ of the International Socialist Women.

In the 1908 was the socialist Corinne Brown to chair the conference held every Sunday by the Socialist Party of Chicago: that conference, to which all women were invited, it was called "Woman's Day". They discussed about most important problems,for example, sex discrimination and the women's right to vote. Later the American Socialist Party urged all local branches to reserve the last Sunday in February 1909 in organizing a demonstration in favor of the right to vote for women. So the first official Women's Day was celebrated in USA on February 23, 1909.

This celebration takes place for the first time in the United State in 1909 , in some European countries in 1911 and in Italy in 1922 where he still plays today.
