Worry has given way to a “nice rooted phase” for artist Ginny Parsons. Her mixed-media paintings of oil spills and endangered birds were infused not only with beeswax, stain remover, and detergent—“the materials of motherhood” —but also “some inescapable evidence of a world bigger than the happy ending.” Rather than a warning or lamentation, her current work celebrates a local microcosm of nature: Lincoln Park, so close to her home studio that it is practically an extension of her backyard.
