Pumpkins are often associated with the Halloween celebration. Before people carved pumpkins for Halloweens, they often carved large turnips and potatoes. Pumpkins are so widespread, they grow on every continent except for Antarctica and there are over 45 different types of pumpkins. Most surprisingly, not all of them are orange with many growing in different colours like green, red and yellow. The largest pumpkin ever grown weighed over 1100kg and each pumpkin contains around 500 seeds.
