The verdant colors of spring and summer can live all year long with greenery walls. This trend brings the outdoors in — framed as art, erected as room dividers and positioned to enliven forgotten corners. Greenery walls — also called plant walls, living walls or vertical gardens — allow urban dwellers to incorporate nature into their environments, satisfying their need to embrace the natural world and providing much-needed health benefits, including improved air quality. Some greenery walls, such as vertical planters that create organic separation between room or border conversation areas, make use of live plants when it’s convenient to provide the essentials of water, food and sunlight. Other décor choices, like framed gardens above fireplace mantels, rely on natural elements that don’t require much care, such as moss and cacti.
