Arts and Sciences Mall Display Garden This mall area connects Speakers Circle and Rollins Street. The Hydrangea Collection is along the East side against the Arts and Sciences Building. A series of planters down the middle are planted with Littleleaf Lindens (Tillia cordata), Boxwoods (Buxus sempervirens 'Green Velvet') and many varieties of shade-loving perennials and also annual flower display areas. A fountain adds sound to the area. Red Oak (Quercus rubra) shows its fall color in the background. Tulips add bright spring color.
