Perennial Drought-Tolerant Ground Covers

A preferred turfgrass often does not grow very well in dry soil, but most types of weeds do not have this problem. Regrettably, weeds will quickly invade a bare patch and take it over. This is why it is important to know about perennial drought-tolerant ground covers.

If you have ruled out turfgrass as an option or simply wish to grow perennials in a dry location because they are more attractive or more interesting than grass, a drought-tolerant ground cover is likely perfect. These perennials offer an alternative to bare ground or weeds. The suggested plants and tips for growing them will help you get started with drought-tolerant ground covers.

    Angelina Sedum

    Angelina sedum or "stonecrop" is a flowering ground cover. In this case, however, the blossoms take a backseat to the foliage. Gardeners value Angelina as a low-growing plant with chartreuse foliage. As a bonus, this perennial drought-tolerant ground cover spreads quickly, effectively filling in your problem area, with a little help from you (in the form of laying down mulch). Like many succulents, it will root where its leaves come into contact with the soil, permitting it to multiply.

    Yellow Alyssum

    You are probably familiar with sweet alyssum, which is treated as an annual plant in the North. It is very popular in the U.S. as the white element in July 4th plantings, where a red-white-and-blue color scheme is called for. But in this entry, we are talking about a different kind of alyssum.

    Yellow alyssum (Aurinia saxatilis) is a hardy perennial. Like Angelina sedum, it sports attractive leaves -- in this case, leaves of a blue-gray or gray-green color. But unlike Angelina, Aurinia saxatilis is grown more for the display created by its flowers. It looks especially nice tumbling over stone walls.​

    Pictured here is purple ice plant (Delosperma cooperi). Like Angelina sedum, this plant is a hardy perennial. Like Angelina sedum, it (Delosperma cooperi). Like Angelina sedum, this plant has succulent leaves and is suitable for xeriscaping.

    Not only is this a drought-tolerant ground cover, but it positively does not like for its roots to be sitting in moisture. For that reason, ice plant can be challenging for someone experimenting with it for the first time. So unlike the other plants listed here, one would not classify this plant as easy to grow.

    Still, its flowers are gorgeous, so why not give it a try? Its unusual foliage (the look of which gives it its common plant name) is moderately attractive, as well.

    Candytuft may be the favorite perennial, hands down, especially among those who love intensely white flowers. Unlike the other plants featured here, though, it does not bear attractive leaves. No, it is all about the flowers with candytuft. But oh, what flowers! Not only are they breathtaking when massed together, but each individual bloom will merit close study if you enjoy intricate patterns.

    Vinca Minor

    With Vinca minor, we come to a plant that is somewhat problematic. That is because this viny plant, which features glossy leaves and blue flowers, and which is often grown in shade-covered areas, has made many a list of invasive plants for North America.

    The fact that some drought-tolerant ground covers are at least mildly invasive should not surprise us very much. After all, plants such as Vinca minor and Japanese pachysandra need to be tough to survive in dry soils. And they do not turn that toughness on and off to please us. A tough plant will, in many cases, out-compete its competition for available resources, including water. Another example that is tempting to plant but definitely invasive is lily-of-the-valley, famous for its great-smelling blooms that resemble little bells.

    You will have to make up your own mind as to whether you wish to grow plants such as Vinca minor. Using this background about the plant, you can make an informed decision.

    Bugleweed or Ajuga

    Bugleweed (Ajuga) is another invasive plant. It is more difficult to control than Vinca minor, so this article is certainly not urging you to grow it. You likely will grow tired of pulling it out of places where it does not belong in your landscaping, frankly.

    Nonetheless, some folks might consider growing this drought-tolerant ground cover under certain conditions. Its proponents point to its spiky flowers and (in the case of some cultivars) attractive leaves as selling points, although anyone who has had to battle this aggressive plant for years would be unlikely to be among those "sold" on bugleweed.
