The pancake-flat fields stretching north from Leiden towards Haarlem are the heart of the Dutch bulbfields, whose bulbs and blooms support a billion-euro industry and some ten thousand growers, as well as attracting tourists in their droves. Bulbs have flourished here since the late sixteenth century, when one Carolus Clusius, a Dutch botanist and one-time gardener to the Habsburg emperor, brought the first tulip bulb over from Vienna, where it had – in its turn – been brought from Asia Minor by an Austrian aristocrat. The tulip flourished in Holland’s sandy soil and was so highly prized that it fuelled a massive speculative bubble. At the height of the boom – in the mid-1630s – bulbs were commanding extraordinary prices: the artist Jan van Goyen paid 1900 guilders and two paintings for ten rare bulbs, while a bag of one hundred bulbs was swapped for a coach and horses. When the government finally intervened in 1636, the industry returned to reality with a bang, leaving hundreds of investors ruined – much to the satisfaction of the country’s Calvinist ministers, who had long railed against such excesses.
Other types of bulbs apart from the tulip have also been introduced, and nowadays the spring flowering season begins in mid-March with crocuses, followed by daffodils and yellow narcissi in late March, hyacinths and tulips from mid-April through to May, and irises and gladioli in August. The views of the bulbfields from any of the trains heading southwest from Schiphol airport can often be sufficient in themselves, the fields divided into stark geometric blocks of pure colour, but, with your own transport – either bicycle or car – you can take in their particular beauty by way of special routes marked by hexagonal signposts; local tourist offices sell pamphlets describing the routes in detail. You could also drop by the bulb growers’ showpiece, the Keukenhof gardens. Bear in mind also that there are any number of local flower festivals and parades in mid- to late April; every local VVV has the details of these too.
