Completed on June 30, 2010, SEDUM TILE® with native California perennials incorporated was custom grown for the green roof on the City College San Francisco Joint-Use Classroom Building. Many other sustainable elements were designed into the project targeting a LEED Platinum rating.

The unique SEDUM TILE® grown for CCSF included Sedum divergens, Sedum cauticolum, Sedum oreganum, Sedum sexangulare, Sedum spurium 'Fuldaglut', Sedum spurium 'John Creech' as well as California Poppy, Lupine, Beach Grass, and Sand Strawberry.

SEDUM TILE® for the 20,000 sf green roof was delivered to the jobsite on 3 trucks. Pallets, 32 shipping trays high, were easily staged in the parking area while waiting to be conveyed to the roof.

SEDUM TILE® can be quickly planted as it is unpacked at roof level. Experienced landscape installers on this project planted TILE® over 2" of green roof media and drip irrigation at a rate of 1,000 sf/mh. (Planting only) At 3 weeks post installation, the Sedums are becoming very well established on the roof. Sedum spurium 'Fuldaglut' adds a striking red hue to the 'green roof'.

At 7 weeks post installation, the California natives are really starting to establish themselves. The native perennials will bloom and later die back until next season. The Sedums will continue to provide color year-round.
