Orange trees are a popular selection for gardeners in citrus-friendly climates. While grapefruits, mandarins, and acid fruits are also favored, sweet and juicy oranges are the most popular. In addition to producing tasty fruit, the trees have ornamental value, too. When in bloom they will perfume a landscape and a well-maintained tree makes a striking focal point. Plant an orange tree where it can be enjoyed from outdoor living spaces but far enough removed that any falling fruit will not create a messy problem.
