Featured in Feb/Mar 2013 issue of Organic Gardening Magazine, this Boston-area courtyard functions as an entryway, parking space, driveway turnaround, and outdoor room. New York bluestone planks set into a sea of pea gravel can bear the weight of vehicles while allowing rainwater to permeate the ground, preventing run-off. Curving 7-foot-high green walls of shade-loving native plants create privacy and beauty, while native birch trees (Betula papyrifera) in the entry planters provide a handsome complement to the four-story Silver LEED-certified house by Wolf Architects, Inc.
