Keukenhof is known worldwide for its tulips. Each year, over 7 million flower bulbs are planted across the gardens' 32 acres by gardeners who work year-round, resulting in a stunning display of spring flowers. Gardeners employ techniques such as "lasagne planting," where bulbs are layered according to their blooming period to ensure a continuous display of flowers throughout the garden's opening season. The riotous colors created by the tulips, daffodils, lilies, roses, carnations, and hyacinths are truly a once-in-a-lifetime experience.
Keukenhof also hosts an annual Tulip Festival between March and May, which features flower shows, parades, musical events, and more. It attracts over a million visitors yearly and is a Dutch calendar highlight.
