Low-Water Garden Plants

Many home gardeners choose low-water garden plants for their landscape, especially if they live in a hot, dry climate. Supplemental watering is often difficult and expensive in such areas, so drought-tolerant plants are a necessity. Choosing plants that require little water to thrive is not only a responsible thing to do, but it is also rewarding.

Blanket Flower

Blanket flowers (Gaillardia pulchella) are low-growing, mounding perennials treated as annuals in freezing climates. Desirable for their brightly colored, two-toned flowers, these plants reach a maximum height of 2 feet and spread of 12 inches, according to Floridata. Blanket flowers bloom in the summer and thrive in hot, sunny locations and dry areas such as rock gardens. They do not like overly wet soil, which will rot the roots of the plant. Blanket flowers grow best in USDA Hardiness Zones 5 to 10.

Globe Amaranth

Globe amaranths (Gomphrena globosa) are annuals that come in a wide variety of flower colors. Their round flower heads are shaped like those of clovers. The plant can grow to a maximum height and width of 20 inches. The long-lasting blooms make excellent cut flowers, according to Washington State University Extension. Globe amaranths thrive in full sun and USDA zones 7 to 10.

Pink Evening Primrose

Pink evening primrose (Oenothera speciosa) produces delicate, baby-pink flowers that are not indicative of the plant's hardy nature. The flowers bloom in early spring and are about 2 inches in diameter. This tender perennial plant spreads on runners and can reach 24 inches tall and 15 inches wide. Pink evening primrose thrives even in poor soils but will die if the soil is too wet, according to Floridata. It grows best in USDA zones 5 through 9.

Butterfly Bush

The butterfly bush (Buddleja davidii), which attracts hordes of butterflies, is very hardy and drought-tolerant. Considered an invasive plant or weed in many states, including Oregon and California, butterfly bush will spread unchecked in natural areas. Home gardeners can keep them in check by easily removing or mowing over young seedlings. Clusters of bright purple, red, pink or creamy white flowers appear in the spring and continue to bloom all summer long. The clusters can reach 18 inches long and also attract other nectar-loving insects and birds. The butterfly bush can grow to 12 feet tall and 15 feet wide. It grows best in full sun or partial shade on dry, well-draining soils in USDA zones 5 to 10.
