About blooming time: All those April showers brought plenty of May flowers to the gardens at Monticello. Peggy Cornett, the estate’s curator of plants, leads the annual Spring Wildflower Walk at TJ’s place. And if the rigorous five-mile hike gave you pause in the past, you’re in luck: This year’s event is virtual, which means you can enjoy the beauty of the grounds from the comfort of home during a 35-minute tour that features Cornett’s extensive knowledge of spring botanicals, and a live Q&A.
