The Illinois Department of Agriculture put a new spin on Springfield’s green scene. In 2010, the department added Illinois’ first “green” roof to its building by planting more than 22,000 square feet of sedum, a small ornamental plant, in 2-by-2-foot trays.
Thanks to the sedum, the eco-friendly roof can retain as much as 75 percent of stormwater runoff.
