No need to don your Aunt Cordelia’s jewels or fake an upper-crust Oxbridge accent for this garden party—Art in the Park is open to the hoi polloi. As its name suggests, this event presents botanical-themed art among the lush plantings of the Washington Park Arboretum, along with a samplings from local vintners Nota Bene Cellars, Ott & Murphy Wines, and OS Winery. But unlike the garden parties of 19th-century Brit lit, admission tonight doesn’t require an old-money pedigree—or, indeed, any money at all. It’s classy without being classist. If you’ve got the means, however, feel free to splurge on some aesthetic additions for the manor. Works on display will include the elaborate paper cuttings of Alisa Lahti, the nature photography of Lee Rentz, and the organic-looking pottery of Maria Root. A portion of artists’ sales benefits the Arboretum Foundation. ($25 suggested for wine tasting.) REBECCA COHEN
