We didn't need to worry. It is true that it was on the late side, but the Keukenhof planters know what they are doing. The practice "lasagne" style planting, which basically means that they plant bulbs at three different depths according to when they bloom. The result is continuous blooms for weeks.
It was interesting to compare these gardens with the Japanese garden we had visited in France. A similar effect resulted from banking swaths of flowers to paint masses of color using thousands of individual flowers.
One section of the garden is planted in a more traditional style with pruned shrubs and cascading fountains reminding us that tulips have been grown in the Netherlands for four hundred years since they were first brought from Turkey.
The vast fields that lie around the gardens where tulips bloom in multicolored stripes were largely bare. This was the part that we were too late too see. But he rest of the gardens were so beautiful that we left satisfied and pleased.
We headed to Amsterdam where we dropped our bags at our apartment and returned the rental car. Then we walked along until we found a restaurant for dinner. We sat at a window with the Rijksmuseum on one side and the Concertgebouw on the other.
