Atlanta Botanical Garden has launched a new flower show, bringing back an old tradition to the city. “It’s been a five-year drought for Atlanta,” Mary Pat Matheson, Atlanta Botanical Garden president and CEO, said Thursday night at a preview party for the flower show. She was referring to the Southeastern Flower Show, which hosted its last show in 2013. “It is so wonderful to finally have rain on this city in the form of a beautiful flower show,” Matheson said. “I think we made some magic.” The flower show runs Feb. 23-25 at Atlanta Botanical Garden with a theme that salutes the state’s film industry. Attendees will see flower interpretations of classic films, such as “When Harry Met Sally” and “Shakespeare in Love.” The flower show includes competitions for artistic floral design, horticulture, photography and landscape design. Beautiful blooms are on display, from camellias to begonias. Pat Hartrampf, who resurrected the Atlanta Flower Show in 1988 that in 1994 became known as the Southeastern Flower Show, is the honorary chair for her contributions to the city’s floral scene. The show co-chairs are Mary Wayne Dixon and Mary Katherine Greene.
