Tulips are such a beautiful herald of spring. Tulips are known for their bold colors and beautiful shape, and most varieties are indeed almost perfectly symmetrical. The blooms have three petals and three sepals, but since the sepals are almost the same size and shape as the petals, tulips appear to have six petals to a bulb. At one point in history, tulips were the most expensive flower. In fact, in the 1600s the flowers were more valuable than most people's homes, and cost almost 10 times what an average working-class man earned in a year. Tulips are a part of the Liliaceae family, which also contains lilies, onions, garlic and asparagus. They are an edible replacement for onions in many recipes and can even be used to make wine!
