If you are dealing with water restrictions, have a lackluster irrigation system or simply want to conserve resources, adding plants that don’t get thirsty is a smart way to green up your outdoor space. Yes, you heard that right; I said “green.” Because while replacing lawns with gravel and hardscape may look natural in arid climates, some areas beg for lush, colorful plantings without a cactus in sight. Dry conditions don’t have to mean sacrificing your lawn. Zoysia, a warm-climate grass native to China, Japan and other areas of Southeast Asia, provides a lush, green carpet without adding an extra digit to your water bill. While this species will eventually yellow in the driest conditions, it is extremely hardy and will bounce back with the first soaking rain. Plus: no mowing required.
