Greenwich's history of elaborate gardens takes the spotlight in new exhibit Rosemarie T. Anner FacebookTwitterEmail Maggie Dimock places a finger on a sheet of paper torn from a pocket-size notebook. Her very precise cursive script on the paper, appropriately small for the page, identifies the pamphlet beneath it as describing The Orchards, later known as Seabury House off Round Hill Road in Greenwich. Dimock touches the notepaper with such reverence as if she were caressing a rare jewel. Curator of exhibitions and collections at the Greenwich Historical Society, Dimock mounted an impressive exposition on the exuberant gardens of Greenwich that flourished when mansion-building transformed the town into a Gold Coast suburb. “Beautiful Work: The Art of Greenwich Gardens and Landscapes” runs through Sept. 5. She spent weeks gathering material that will “celebrate the ambition, industry and delight” of gardens that characterized the great estates of Greenwich,” she said.
