We've all enjoyed the fruit of orange trees. They also have other value. The leaves and flowers are used for tea. The flowers, with their delightful scent, are used to make perfume. A few flowers added to a glass of water give it a delicate citrus flavor. Honey from the orange grove beehives is outstanding! Orange wood is used for small items, and rather obviously for orange crates. Maybe only we older folks remember those. These trees have been known as Citrus aurantium.
