What plant selection options are available with the GreenGrid® system?
Plants are one of the most vital components of a green roof. In traditional built-in-place green roof systems, plants are set in after the roof system is in place, a very labor-intensive process. With the GreenGrid® system, the modules are preplanted with plants of the color and type selected by clients. At the owner’s request GreenGrid modules can also be grown out at the nursery for a period of time before installation in order to have a more mature green roof at the time of installation. The 4-inch depth modules (Extensive systems) are generally composed of highly drought resistant ground covers, while the 8-inch modules (Intensive) will support a variety of larger ornamental plants. Plants are placed in the modules at the nursery and cared for until they are shipped to the green roof site for installation. A preset “palette” of plants, developed by staff horticulturists, is available to allow customers to select plant varieties according to plant hardiness zone, size, and color.
