caprifig

Caprifig refers to the wild or non-edible form of the common fig tree, scientifically known as Ficus carica var. caprificus. Caprifigs produce small, inedible syconia that exist primarily to host the life cycle of the fig wasp Blastophaga psenes. The term is often used to distinguish these trees from the cultivated, edible fig varieties that bear large, sweet fruit.

The biology of caprifigs is central to the fig-wasp symbiosis. In spring, caprifig trees produce syconia that harbor developing wasp larvae. Female wasps emerge, carrying pollen from the caprifig’s male flowers, and seek out receptive flowers in nearby edible fig syconia. The female enters the edible fig through the narrow ostiole, pollinates the flowers inside, and then, after mating with any male wasps that may be present, dies. The pollinated edible figs can develop seeds, and the life cycle continues when new wasps emerge from the caprifig and repeat the process.

Caprification, the traditional practice of using caprifigs to pollinate cultivated figs, has historically been important in Mediterranean agriculture, particularly for Smyrna-type and other seed-containing fig cultivars. This method often involved placing or allowing caprifigs near or within orchards during the pollination window to ensure wasp transfer. In modern horticulture, many edible fig varieties are grown without caprification, especially seedless types, but caprifigs and caprification remain culturally and historically significant in regions where pollinated figs are valued.
