The exhibit, which runs through Oct. 30, features nearly 100 miniature buildings made from natural materials like bark, acorns and gourds. While the models are touched up annually, this year the exhibit got an overhaul, replacing all 26 of the garden's willow bridges and other aging structures and adding several new buildings and trains.
The garden's theme is landmarks of America, and the buildings are scaled to match the size of the 17 model trains that run through it. Horticulturists work hard to keep the garden's 5,000 plants in scale.
