Gallery review: Here comes summer

Summer has started early, judging from the number of group shows already under way in Philadelphia galleries. Nature, rendered in almost every form imaginable, is the chief subject. Sienna Freeman, Wexler Gallery’s director and an artist herself, is the curator behind Wexler’s “Wild Nature,” a gathering of four artists from across the country and Canada who envision nature through the lens of memory, dreams, and natural-history museum dioramas.
