figures: BKD
The other bulb flowers are fairly stable: the daffodil decreases slightly, the hyacinth increases a bit, the rest remains about the same. Incidentally, none of these crops is in any relation to the tulip: daffodil and hyacinth amount to 1,200 to 1,300 hectares, crocus and allium fluctuate around 200 and 300, muscari between 150 and 200 and the remaining exclusive species on a few dozen hectares.
