High Quality Content by WIKIPEDIA articles! The Tulip Festivals are held in several North American cities, most often ones with Dutch heritage, including Albany, New York; Ottawa, Ontario; Holland, Michigan; Orange City, Iowa; Pella, Iowa; Mount Vernon, Washington; and Woodburn, Oregon. The tulips are considered a welcome harbinger of spring, and a tulip festival permits residents to see them at their best advantage. The festivals are also popular tourist attractions. The tulips are displayed throughout the cities. In certain years the peak of tulips does not coincide with the actual festival due to climatic conditions. The tulip-festivals are being held in honour of the Dutch-American immigrants who brought the (then highly expensive) tulips to the Americas.
