Rian and Melissa Jorgensen’s Menlo Park, California, home boasts the usual components of green design: energy-efficient lighting, good insulation, renewable material finishes, radiant heat, and a roof that’s prewired for future PV panels. Still, one of the homeowners’ favorite aspects of the residence is the living roof by Lauren Schneider of Wonderland Garden, which is planted with succulents, aloe, viviums, and ice plants that flower in swaths of white and purple.
