The area around Lisse is covered in fields of tulips. They’re grown primarily for bulbs, but some gardens are of the pick-your-own variety. Keukenhof is probably the most popular tulip garden in the Netherlands, where 7 million tulip bulbs are planted each year, according to the office of tourism. The best time to see the tulips is in April and the beginning of May.

In Oregon, the Wooden Shoe Tulip Farm hosts an annual tulip festival from late March through April. More than 10 varieties of tulips are grown there.
Last year, a Dutch couple brought the Netherlands to Italy when they opened a pick-your-own tulip farm outside Milan. The farm, created by Edwin Koeman and his girlfriend Nitsuje Wolanios, covers about 2.5 acres, with 183 varieties of tulips, the Associated Press reported. The tulip season in Italy is only two to three weeks.
Despite the obvious beauty, large-scale flower cultivation has a downside, especially in the Netherlands — fertilizer runoff that infiltrates the ground water and oceans. A recent European Union directive attempted to limit the amount of nitrates used in agriculture, and although the amount of fertilizer decreased in the surrounding waters, the Netherlands was unable to meet its goal.
