The best drought-tolerant plants will take the guesswork out of planting up your backyard if you live in a climate where it doesn't rain much during the summer. Different plants have different tolerance levels for dry spells and some will easily do fine for weeks without water, while others will start wilting after only a few days. Knowing what to plant in a drought-prone backyard is key to enjoying an outdoor space that still thrives even during intense heat.

Many of these are naturally full sun plants, and the best part is that you won't have to worry so much about watering them; plus, at the most they may need – like most plants – some light pruning with good secateurs. Needless to say, creating a drought-tolerant planting scheme is also great for wildlife and for water conservation so they make no-brainer additions to every modern outdoor space.

Introducing drought-tolerant plants to your backyard can start with selecting a few species to begin with. Karen Musgrave, a gardening expert from Hicks Nurseries, recommends sedum, which is 'drought tolerant and looks great in garden beds, along sunny walkways and in planters. There are several types from tall, upright varieties down to low-growing groundcovers. A perennial, sedum comes back every year and requires very little maintenance.'

Next, as part of updating your garden ideas, consider introducing a few flowering varieties such as coneflower - 'the perfect option for a sunny garden and requires little maintenance once established' - and yarrow, 'a great option for hot, dry gardens. It has flat-topped flowers that bloom late spring to late summer and is a known favorite of butterflies.'

Yes. Sedum, is a succulent and most other varieties of succulents are drought resistant as they store water in their leaves. The same goes for cacti; both types of plants are highly suitable for xeriscaping and desert climates where these plants come from.
