Brief SummaryRead full entry
The fig is a many-branched shrub or small tree, to 3 to 9 m (10 to 30 ft) tall, but rarely reaching diameters of more than 17.5 cm (7 in). The trunk and branches contain large amounts of milky white latex, like various other Ficus species, including F. elastica, which was formerly used as a source of latex for rubber. The leaves are alternate, thick, and palmately, with 3 to 7 deep dissections, each coarsely toothed. Leaves are up to 25 cm (10 long), with a scabrous (rough) upper surface, and pubescent (soft hairy) underneath. The synconium (fruiting structure) that grows in the axils (where leaf meets stem) may range in color from yellow to green to purple to bronze on the outside, with 30 to 1600 tiny flowers inside.
Some female fruits may develop without pollination, but others require pollination with male fig flowers, or cross-pollination, in order to develop. Pollination occurs in a tightly coevolved interaction with only one species of specialized fig wasp, which crawls inside a small hole in the tip of the syncomium. The female wasp lay eggs inside the receptacle then dies, but the offspring generally complete their lifecycles, hatching into larvae, pupating, and emerging as adults, that leave the syncomium as the fruit ripens. The seeds that develop are embedded in a fleshy wall, which turns sweet and juicy when the “fruit” is ripe.
Figs, which are high in carbohydrates, vitamin K, and are a good source of minerals including calcium, magnesium, potassium, and manganese, are eaten fresh or dried. They are used in numerous dessert and baked goods, as well as jams, and preserves, as well as in some savory and meat dishes.
FAO estimates that 2010 commercial production of figs was 1.1 million metric tons worldwide, harvested from 376,186 hectares. Turkey and Egypt are the leading producers, together accounting for around 40% of the total, followed by Algeria, Iran, and Morocco. The U.S. ranks 7th for production
F. carica has been known to escape cultivated plantings and gardens, and is considered introducted in several U.S. states, including California, Florida, North and South Carolina, and Massachusetts, and southeastern states ranging from Alabama to Texas. Although it may persist outside cultivation, it is not generally considered an aggressive invader.
