The most important thing about spring in Holland is, of course, flowers - and there will be flowers galore. We will visit the world famous gardens of Keukenhof, the bulb grower's magnificent display of all the different tulip, daffodil and hyacinth varieties - over 6 million bulbs are planted annually and Dutch horticulturalist Piet Oudolph's Nursery. The grand gardens of Het Loo Palace are now recognised as one of Europe's finest formal gardens, a late Dutch interpretation of the Italian-French garden dating from the first quarter of the seventeenth century.
