Kaffir Lime Tree

[Dave]

The Key lime also known as a Mexican lime, West Indian lime, Bartender's lime, or common lime; has a globose fruit, 2.5-5 cm in diameter (1-2 in), that is greenish-yellow when ripe but usually picked green and valued for its sourness and flavor. The Key lime, along with the larger but less flavorful Persian lime, is one of two citrus fruits identified as sour or acid limes, and often sold generically as a "lime".

Key lime is a shrubby tree, to 5 m (16 ft), with many thorns. Dwarf varieties are popular with home growers and can be grown indoors in winter in colder climates. The trunk rarely grows straight, with many branches that often originate quite far down on the trunk. The leaves are ovate 2.5–9 cm (1–3.5 in) long, resembling orange leaves (the scientific name aurantifolia refers to the leaves' resemblance). The flowers are 2.5 cm (1 in) in diameter, are yellowish white with a light purple tinge on the margins. Flowers and fruit appear throughout the year but are most abundant from May to September.

The Kaffir Lime s native to Southeast Asia. Its apparent path of introduction was through the Middle East to North Africa and Europe during the Crusades, via Spanish explorers to the West Indies (at some point including the Florida Keys) contemporaneously with Columbus, then tropical and sub-tropical North America including Mexico, Florida, and later California. The English name "lime" was derived from the Persian name لیمو Limu in this course. "Key" would seem to have been added some time after the Persian lime cultivar gained prominence commercially in the United States following the hurricane of 1926 that destroyed the bulk of U.S. C. aurantifolia agriculture, leaving it to grow mostly casually in the Keys . Since the North American Free Trade Agreement came into effect, many key limes are grown in Mexico and Central America. They are also grown in Texas and California.

The fruit is smaller, seedier, and less hardy than that of the Persian lime, but has a stronger aroma and acidity, as well as a thinner rind. It is perhaps most distinguished as an ingredient in the eponymous Key lime pie. It is also favored in drinks such as the margarita.
