Limes are native to Southeast Asia, and originated in Indonesia or Malaysia. They made their way to the eastern Mediterranean with the Arabs, and to the western Mediterranean, with returning Crusaders, and eventually to the West Indies, when Columbus introduced citrus fruits there on his second voyage. These limes, used in most of the world, are what we call Key Limes.

Propagation:
By seeds. Also by grafting, with which trees tend to produce fruit a bit faster (3-4 years, vs. 4-7 for seedlings). Note on seeds: Seeds are harvested fresh, but to successfully germinate citrus seeds, a constant soil temperature at 75-85F is a must. Water moderately, only when the surface begins to dry. Over-watering can lead to rot. Sprout in shade, greenhouse or filtered sun.

Key Limes are used for key lime pie, beverages, sorbets, and jams. They are excellent in marinades for fish (seviche) or meats and chicken, and used in fish and meat stews.
