I just saw photos from the 2012 Bloemencorso Zundert flower parade in Zundert Netherlands. To say the least.. mind blown!
Bloemencorso Zundert is the largest flower parade in the world entirely made by volunteers. The parade takes place on the first Sunday of September. Foats are large artworks made of steel wire, cardboard, papier-mâché and flowers.
In the Bloemencorso Zundert, only dahlias are used to decorate the objects, and it takes thousands of them just to cover one float. The huge floats are made by twenty different hamlets and each of them consists of hundreds of builders, aged 1 to 100, who are all equally crazy about the bloemencorso.
The older members of the hamlet are often responsible for planting and growing the dahlias, while the younger ones build the float in large temporary tents that are built exclusively for the event. The bloemencorso is also a competition. A professional and independent jury decides which float is the most beautiful and which hamlet will be crowned the winner of that year.
