Our Top Picks for the Best Drought Tolerant Plants

Drought Happens

At any given time, parts of the country experience drought-like conditions. It can range from abnormally dry to extreme drought that may be a short-term occurrence or one for the long haul. Over 1.5 billion people around the world have been affected by drought between 1980 and 2014. Drought costs money and lives. Each year it costs the global economy over $2 billion.

One way to prepare for it is by planting drought tolerant plants in your yard. They can help keep the soil intact when a lack of rain can increase the risk of erosion. Recognizing its impact, scientists and horticulturists have worked to develop plants that can handle dry conditions to offset the economic burden of drought. Fortunately, that includes drought resistant plants for your garden.

 

What You Need to Know about Drought Tolerant Plants

In areas where drought happens often, you’ll find plants that have evolved strategies for coping. Some are nothing short of amazing. Some involve changes to the structure of plants. Others include taking advantage of the timing to minimize water loss. Whatever the strategy, these plants manage to survive in conditions that would break many other plants.

Native Plants

Good examples of drought tolerant plants exist with native varieties. These plants know what it takes to survive in their native climates. They’ve stood the test of time. They can give you a head start for finding the right drought tolerant plant for you. You’ll likely find different cultivars of native plants that capitalize on some of their outstanding features. The other advantage is maintenance.

Native plants often need less maintenance than exotic varieties. They may cope better with the occasional dry spell that is typical for your area. Some plants like prairie grasses thrive better if you don’t have to water or fertilize them. If you’re looking for a quick solution, you may want to consider plants that are perennials, native to your area, or at least from places with similar conditions.

How Plants Cope

Plants in dry areas face two challenges. They must minimize water loss and maximize the use of the moisture they find. One way they do this is with smaller leaves or needles. Plants exchange gases and water with openings in their leaves called stomata. The smaller the surface area of the leaves means a reduction in water loss. The needles of cacti are very small leaves.

You’ll find plants with thick fleshy leaves like cacti and succulents that allow them to retain water. Some plants take it one step further with a waxy coating that helps keeps water in the plant. The white fir is one example of this strategy. Prairie plants like big bluestem have deep root systems that can reach down over 10 feet. That keeps them close to water even if it’s hot.

Plants even change their day-to-day rhythms to cope. Some plants, for example, have a different way of undergoing photosynthesis so they can maximize the amount of resources they have and minimize losses. Other plants like cacti take advantage of the cooler evening hours to carry out respiration. During the hot day hours, their stomata remain closed to prevent excess water loss.

Benefits of Drought Tolerant Plants

The clear advantage for gardeners of plants adapted to dry conditions is that they can survive. They have some coping strategy to withstand long periods without precipitation. That’s one cost-saving factor. The other one lies with maintenance. A drought tolerant plant won’t need extra watering during dry spells. You’ll save money and time with plants that don’t need extra care.

Choosing drought-tolerant plants is also the eco-friendly choice. If you live in a drought-prone area, you likely have watering restrictions. But that doesn’t mean you must give up your dream of a garden. We found many beautiful plants that can handle dry conditions. You can feel good about choosing plants that have less of a negative environmental impact.

Choosing Drought Tolerant Plants

Picking the right plant for your location begins with the ones rated for your site’s USDA Hardiness Zone. While you may associate drought with heat that’s not always the case. Cool, dry conditions can challenge plants just as much as warmer temperatures. As a general rule of thumb for all plants in your garden, make the type match your local conditions.

Perennial plants will need some time to get established. The move from the nursery to your garden is stressful. They must set down roots to tap into nutrient and water resources. During this time, it’s a smart plan to help tolerant perennials along before their own coping strategies take over. That may mean watering or mulching plants to help them minimize moisture loss.

Your plants will also fare better if you group plants based on their needs. Place plants with similar requirements for sun and moisture close together. That will make your task much easier when it comes to maintenance. It’ll also benefit the plants. With similar patterns of photosynthesis and respiration, they can cope better during trying times.
