Watermelon was grown by the ancient Egyptians and it’s still evolving today. More than 300 varieties of watermelon are cultivated in the United States and South America, where complementary growing seasons provide a year-round supply of watermelon in an array of shapes, colors and sizes. The development of seedless varieties revolutionized the watermelon market, making this age-old fruit appealing to today’s more discriminating consumers. Because there are so many varieties, they are often grouped according to characteristics, like fruit shape, rind color or pattern and size. Other varieties, like yellow and orange flesh watermelon, have also created additional intrigue and appeal, opening up the market to new consumers.
