The previously dubbed Smithgall Woodland Garden is now called the Atlanta Botanical Garden, Gainesville. Mary Pat Matheson, president and CEO of the garden, said there were several reasons for the change, the biggest being the need for clarity. “When we started looking at branding the garden to the Atlanta Botanical Garden ... the more we tested the garden name, the more we realized there was going to be confusion over Smithgall Woods (State Park),” Matheson said.
