Looking for a hardy, evergreen tree that produces sweet and nutritious pods? The Ceratonia siliqua, also known as the carob tree, St. John's Bread, or locust bean, is a great choice. Native to the Mediterranean region, this xerophytic species is well-adapted to warm temperate and subtropical areas, and can even tolerate hot and humid coastal regions. The tree's pods are filled with a saccharine pulp that can be eaten green or dried. Because of their high sugar content, carob pods are sweet-tasting and mildly laxative. They are also packed with nutrients. In fact, some Christians believe that St. John the Baptist subsisted on them in the wilderness. The carob tree is not just useful for its edible pods, but also for its ornamental value. Its rounded habit and evergreen compound leaves make it great for landscaping. No wonder it is widely cultivated!
