Figs are harvested for both fresh consumption and processing. There are three main types of cultivated Ficus carica: Common, San Pedro and Smyrna. Common figs produce fruit parenthocarpically, without any pollination. Smyrna figs require pollen transfer from male trees that produce small caprifigs for fruit growth. Pollen transfer is obtained by the fig wasp (Blastophaga psenes L.), a species unable to survive the southern U.S. winter temperatures. San Pedro figs are intermediate between the two; a minor summer "breba" crop will set without fertilization but the later main crop requires pollination by the fig wasp. The common fig is the only type suggested for cultivation in the southern U.S.
