RaleighIn this episode we visit three gardens in Raleigh, North Carolina. In nearby Durham, a tree-covered lane draws visitors into a 55-acre haven located at Duke University. Sarah P. Duke donated $20,000 in 1935 to start this garden. Features include a terrace garden, native garden and an Asiatic arboretum designed around a 1.5-acre lake. The town the next garden is located in is so small it's not even on the map! When this garden was started in 1987, it was just a sandy tobacco field with an arched oak that now serves as a portal to the garden. A path leads to a secret waterfall that simulates a mountain waterfall. Montrose, the third garden, is hidden by ivy-covered walls and a gate; this was the home of a 19th-century governor. Old oaks grace the front of the home and have been there since the garden began almost 200 years ago. Finally, we visit an old-fashioned garden. A fence atop a hill hides this private garden. A stone path leads from the patio garden into a woodland paradise with garden sculptures. The steep slope gives the garden its character and allows garden treasures to be tucked into hillside coves.
