Answer: Low maintenance, low water requiring plants are those that are commonly suitable for xeriscapes. One way to tell if a plant is a good choice for a xeriscape is the color of its foliage. Plants with a silvery foliage such as many of the herbs, are almost always drought-tolerant. Some examples of these are the artemisias, catmint, and perovskia (Russian Sage). Other perennials that can also be included in your xeriscape are: Sunny Spots .
