Although the concept of a flower parade is certainly not limited to Holland, it is fair to say that nowhere else in the world are you able to watch so many floral street processions. Each parade - called a 'corso' - has its own history and is typically Dutch. 

'Bollenstreek' flower parade
The 'Bollenstreek' (bulb-growing area) Flower Parade is the first and biggest parade held in Holland every year. 50 years ago, the organizers of various small parades which were held in the villages of the Bollenstreek decided to join forces and created one big parade. It was to become the calling card of the flower bulb culture.

The floats
The floats are created with 1.5 million hyacinths and thousands of narcissus and other flowers. In certain parts of the country, only dahlias are used to decorate the floats. Hundreds of volunteers are busy for months making the floats as beautiful and as striking as possible. 
Spectacular flower parades throughout Holland can be seen from April through to September every year.
