In the United States, pumpkins go hand in hand with the fall holidays of Halloween and Thanksgiving. An orange fruit harvested in October, this nutritious and versatile plant features flowers, seeds and flesh that are edible and rich in vitamins. Pumpkin is used to make soups, desserts and breads, and many Americans include pumpkin pie in their Thanksgiving meals. Carving pumpkins into jack-o’-lanterns is a popular Halloween tradition that originated hundreds of years ago in Ireland. Back then, however, jack-o’-lanterns were made out of turnips or potatoes; it wasn’t until Irish immigrants arrived in America and discovered the pumpkin that a new Halloween ritual was born.
