The LiveWall planted wall system is simple to install and easy to maintain, the company says, with planter modules that slide into mounting tracks that hold built-in nozzles for integrated mist irrigation. The plants grow upward instead of sideways as in many living wall systems for hearty, long-lasting growth, the firm says. The system is available in six colors: beige, cool gray, wheat, cedar, sage, and salsa. 877.554.4065. www.livewall.com.
