Not all the flowers at Keukenhof are outside: the pavilions are also packed with flowering bulbs, cut flowers, pot plants and shrubs. In the Orange Nassau Pavilion you can enjoy colourful floral displays that change every week. The Willem-Alexander Pavilion shows many thousands of tulips and during the last twelve days of the season it is home to the world's largest lily show, a true spectacle. For eight weeks long the Beatrix Pavilion gives you the chance to enjoy a mass of orchids, anthuriums and bromelias. The Keukenhof flower shows offer a unique experience. As many as 500 growers present their prize blooms for leading flower arrangers to use in their unique shows.
