Landscaping activities at the Fair included the planting of over two million flowers and trees. And this figure did not include the plants and gardens found around the state and foreign buildings.
A favorite area was the Sunken Garden between the Palaces of Liberal Arts and Mines and Metallurgy. Here outdoor seats for hundreds of people were available providing visitors a few minutes rest while they enjoyed floral displays that changed with the seasons. Visitors then went to the Cascade gardens to see more colorful blossoms.
Exceptional gardens surrounded the Italian, French, German, Japanese, Arizona and California buildings. Visitors marveled at transplanted trees from Japan and exotic plants from far-away states and countries with climates very different from St. Louis.
