The Netherlands does not have an official national flower, but the tulip is regarded as the unofficial national flower of the Netherlands. The Netherlands produces roughly 9 million flower bulbs a year, and the tulip is the most popular.
There are various tulip-producing regions in the Netherlands, but the most well-known of these is found between the town of Harleem in North Holland and Sassenheim in South Holland. Keukenhof Gardens, in South Holland, is one of the most picturesque planned gardens in the world and over seven million blooming bulbs are grown there each year. This garden is only open two months out of the year, typically between March and May.
