Beautiful! I would just love to see one of these flower fields sometine, they must look just wonderful in "real life" (so to speak) ;-) Unfortunately I didn´t happen to see any when I was in Holland a few years ago. Maybe it wasn´t the right time? (September). Or maybe I just should have tried exploring more. (I drove through Holland with my car on my way northwards from Germany to Denmark).
Of course you can Gunilla. Friends of us have a tulip farm and they export all sorts of tulips and colours to Sweden, and they are not the only ones! So you should be able to buy them in Sweden!
Karl, for the bulb fields you have to visit Holland in the period March until early May. You will find plenty of fields in the western part of the Netherlands in an about 30 km broad strip along the North Sea between The Hague and Den Helder.
