Tulips have been cultivated since at least the tenth century in Persia. Tulip production has two main markets: cut flowers and bulb. The latter are used, in turn, to meet the demand for bulbs for parks, gardens and home use and, secondly, to provide the necessary bulbs for cut flower production. International trade in cut flowers has an approximate total value of 11 billion euros, which provides an indication of the economic importance of this activity. The main producer of tulip bulbs is the Netherlands, a country that accounts for 87% of the global cultivated area, with approximately 12,000 hectares. Other leading producers include Japan, France and Poland. Approximately ten other countries produce commercial tulips, largely for the domestic market. By contrast, the Netherlands is the leading international producer, to the extent of 4 billion bulbs per annum. Of these, 53% are used for the cut flower market and the remainder for the dry bulb market. Of the cut flowers, 57% are used for the domestic market in the Netherlands and the remainder exported.
