Visiting a flower market is one of the best ways to get to know Dutch culture. Some of the best flower markets in Holland have been in operation for centuries. The floating market in the Singel canal in Amsterdam is unique and it is still located on barges in the canal. This stems from the days when flowers were brought to the city over the canals. While the flowers now arrive by truck, the market still floats. Utrecht also has a large flower market on Janskerkhof and on the Oudegracht, and the flower auction in Aalsmeer is first on the list for wholesale buyers from all over the world.
