Flower Bulbs: It's difficult to choose from the incredible variety of bulb shapes and colors offered in Holland. Some bulbs flower early in January; others wait until the warmer months of May or June. Knowing this, choose bulbs with different flowering times, so you'll enjoy their blooming over a long period in spring. Check before buying, however, as not all bulbs are certified for entry into the United States. Packages must have a numbered phytosanitary certificate attached to the label, allowing you to import the bulbs. In Amsterdam, buy them from the Floating Flower market on the Singel canal.
Delftware: Originally, the pottery made in the factories at Delft was white, imitating tin-glazed products from Italy and Spain. But during the 16th century, blue Chinese porcelain was imported to Holland, and this was soon recognized to be of superior quality. So the Delftware factories started using a white tin glaze to cover the red clay and decorating the pottery in blue. This Delft Blue became famous the world over, along with Makkumware, which is pottery produced in the Dutch town of Makkum. Delftware and Makkumware are for sale in specialized stores all over the country, but it's far more interesting to go to one of the workshops in the towns themselves and see how it's made. Little has changed over the centuries, and all the decorating is still done by hand.
