Lemons are one of the important citrus fruits.
Young lemon trees grow rapidly, and tend to be more spreading than oranges or grapefruit. Trees are slightly less hardy than oranges. Fruits are generally oval in shape, about 2.5 inches in diameter and 2.5 to 3 inches long. Most are picked when they reach a certain size and are still green in color. They may be stored up to several months prior to marketing.
