This sedum, a herbaceous perennial, is a staple green roof plant. Growing best in zones 3-9, this succulent is drought tolerant and loves residing in full sun. Small rounded succulent leaves start as a slamon color changing to a bright green and then eventually a rich red color in winter. They bloom small white flowers in early summer. Easily propagated, plant parts that have been cut and spread out will take root with little effort. Growing about 4-6 inches high, this sedum spreads fairly well, creating sufficient ground cover for extensive green roofs.

The coral carpet variety attracts butterflies and seems to be a favorite of pigeons. Jörg and I recently visited ABC's Carpet warehouse in the Brox, complete with green roof space. The pigeons have been pulling apart the coral carpet, leaving small cuttings behind. This isn't necessarily a bad habit, considering these small plant parts will root themselves, creating even more ground cover.
