Figs can be a great addition to a Northwest fruit garden, as long as they have a very warm spot- south facing wall or sun trap.  They can grow up to 12 feet or more but respond wll to pruning.  We prune ours short enough to harvest fruits easily.  Some winters they will get some die back but they usually sprout back vigorously the next spring.  Fig shrubs are elegant and beautiful with open branching.
