Where are the green roofs located?
The Morris Arboretum Horticulture Center has two green roofs constructed on the top of two sloped garage roofs. Visitors can see these two roofs from the walking path to the entrance of the office building. Both roofs visitor’s can view from ground level along the walking path. No access is permitted on the top of the roof where the plants are located. The 4-Bay Garage is designed with a 4″ soil depth that allows mainly sedums to be planted. The 6-Bay Garage has an 8″ soil depth that allows a more diverse group of plants and native grasses to grow. These two roofs will serve as an educational exhibit for visitors and be part of an ongoing research study at the Arboretum. Two green roofs are planted atop the Horticulture Center’s four and six bay garages will serve as examples of “extensive” and “intensive” green roofs. What are the differences between the Intensive and Extensive Green Roofs at the Morris Arboretum?
