Drought-tolerant planting is a must for zones that see little rainfall. But with climate change many of us now experience prolonged dry spells and record-breaking temperatures that make plants that can flourish in dry conditions a great choice.

Plants that are drought tolerant are naturally adapted to flourish when soil is dry. As long as a good root system is established, they require little water even when left directly under sunlight.

For flourishing flower bed ideas when rain is scarce, consider our favorite drought-tolerant planting – perfect for a dry garden.

Drought-tolerant planting: 10 top picks

Follow the lead of gardeners who live in the driest zones by opting for plants that can stand up to extreme conditions.

Whilst we may be able to escape to the shade indoors, our plants cannot. Choosing flowers and shrubs carefully is imperative if you want to achieve a flourishing flower bed throughout summer. By including some of the best drought-tolerant planting, you can ensure a blossoming garden all season long.

So, what types of plants do you need? The plants that can cope with hot, dry conditions usually originate from hot, dry and rocky areas of the world with a warmer climate, such as Florida, Texas and California. They have evolved to thrive in these conditions, which is why you’ll have more success with planting in dry conditions if you choose the right plants. For example, plants with silver foliage are typically from warm and dry regions, as the leaves are able to reflect the harshness of the sun's rays. 

Whatever your taste, you’ll find a plant to suit your style, whether it’s a gravel garden of flowering plants or more exotic varieties. There are a few ways to spot drought-tolerant plants – look at their leaves, as they tend to have one or more of the following attributes: spiky, needles, silver-colored foliage, tiny leaves or waxy leaves. All these characteristics help the plant deal with heat.

1. Verbena

With elegant, bowing flower stems and bell-shaped blooms, dierama is often referred to as ‘Angel’s fishing rod’ and is best planted in spring. Although they are part of our selection of drought-resistant planting, avoid putting them into the ground when the weather is hot or dry, as well as when it is cold.

To make space for the stems allocate plenty of space in borders to dieramas. A clump can reach 5ft (150cm) in height, and 20in (50cm) in width.

3. Iris

When established, iris is incredibly drought-tolerant planting, however newly planted must be watered on a regular basis in order to develop roots. 

To grow irises in your yard, plant in fall if you purchase bulbs. Rhizomes are also best  planted in fall, but if you buy them at a different time of year, plant them then rather than waiting.

Irises are perennials that can flower for many years, so they’re well worth including in borders.

4. Cape daisy

What does it mean for a plant to be drought tolerant

A plant that is drought tolerant is simply one that can tolerate dry conditions. There is actually a wide range of plants that are drought tolerant, including container and border favorites, grasses, perennials, climbers, shrubs, palms and trees.

‘There are many plants that can tolerate drought once they are established,’ says Teresa Conway, gardening writer, Homes & Gardens. ‘You might want to choose them for containers, too, as they’ll reduce the time you have to spend watering.’

What are the best drought tolerant plants?

Plants with silver foliage are able to reflect sun away from the plant, while plants with hairs can trap moisture and those with small or needle-like leaves lose less water through evaporation.

There are also ways to improve your soil conditions to help plants thrive. Many Mediterranean plants like free-draining soil and will not like sitting in waterlogged sites over winter, so it’s important to improve soil structure. 

Once established, you’ll have tough plants that won’t need much care. Drought-tolerant planting is an exciting opportunity to transform problem areas of the garden into a fantastic display – and you won’t have to worry about asking your neighbor to do holiday watering.
