Festivals

Cucurbita fruits including pumpkins and marrows are celebrated in festivals in countries such as Argentina, Austria, Bolivia, Britain, Canada, Croatia, France, Germany, India, Italy, Japan, Peru, Portugal, Spain, Switzerland, and the United States. Argentina holds an annual nationwide pumpkin festival Fiesta Nacional del Zapallo (lit. ' Squashes and Pumpkins National Festival '), in Ceres, Santa Fe, on the last day of which a Reina Nacional del Zapallo (lit. ' National Queen of the Pumpkin ') is chosen. In Portugal the Festival da Abóbora de Lourinhã e Atalaia ("Squashes and Pumpkins Festival in Lourinhã and Atalaia ") is held in Lourinhã city, called the Capital Nacional da Abóbora (the "National Capital of Squashes and Pumpkins"). Ludwigsburg, Germany annually hosts the world's largest pumpkin festival. In Britain a giant marrow (zucchini) weighing 54.3177 kilograms (119 lb 12 oz) was displayed in the Harrogate Autumn Flower Show in 2012. In the US, pumpkin chucking is practiced competitively, with machines such as trebuchets and air cannons designed to throw intact pumpkins as far as possible. The Keene Pumpkin Fest is held annually in New Hampshire; in 2013 it held the world record for the most jack-o-lanterns lit in one place, 30,581 on October 19, 2013.

Halloween is widely celebrated with jack-o-lanterns made of large orange pumpkins carved with ghoulish faces and illuminated from inside with candles. The pumpkins used for jack-o-lanterns are C. pepo, not to be confused with the ones typically used for pumpkin pie in the United States, which are C. moschata. Kew Gardens marked Halloween in 2013 with a display of pumpkins, including a towering pyramid made of many varieties of squash, in the Waterlily House during its "IncrEdibles" festival.
