Later this month, one of Newport’s most spectacular Gilded Age mansions, Rosecliff, which was modeled after the Grand Trianon of Versailles by architect Stanford White for a silver heiress, will host the Newport Flower Show. The historic home’s rolling front lawn will be transformed into a majestic public park with garden displays designed around this year’s theme, Gilded-Artful Living. Along with lunchtime lectures by interior design and garden expert Bunny Williams and floral designer Bruno Duarte, there will be demonstrations, a marketplace, a jazz brunch, and more. The Newport Flower Show, June 24-26 at Rosecliff, 548 Bellevue Ave., Newport, R.I., www.newportflowershow.org
