Will figs grow in Delaware?

Last week, the revised USDA Har­di­ness Zone Map was released. The revi­sion is the first change since 1990. Most loca­tions were moved one-half of a zone higher. The USDA attribute the changes to these cri­te­ria: They used data mea­sured at weather sta­tions over a 30 year period (1976–2005), while the 1990 map used data from a 13-year period (1974–1986).
