With the UK set for another warm spell, gardening expert Chris Bonnett from GardeningExpress has shared six drought-tolerant plants that will add a splash of colour to any sunny garden. These plants thrive in full sunlight and are ideal for south-facing gardens, where intense heat and rapid moisture loss can challenge delicate species.
Why Choose Drought-Tolerant Plants?
Plants in full sun can suffer from scorching and moisture loss, but sun-loving, drought-tolerant varieties can create colour and interest even in bright, warm weather. Despite the UK's reputation for rain, there are many options for south-facing gardens, and planting now offers some real treats.
English Lavender
English Lavender, with its violet-blue flowers and unmistakable fragrance, is a top choice for sunny gardens. This heat-loving plant produces plenty of blooms during hot weather and prevents root-rot, which can occur in shady spots. Intense sunlight triggers oil production in the foliage, resulting in a stronger scent.
Mexican Giant Hyssop
This plant thrives in sunny borders, with dense spikes of flowers adding vertical interest. Once established, its root system makes it highly drought-tolerant, and it won't wilt in harsh, direct sun. Bright sunlight also releases a stronger scent.
Cosmos
Low-maintenance Cosmos is an ideal bedding plant for sunny gardens. It blooms from mid-summer to the first frosts and needs very little care, apart from occasional deadheading. Cosmos thrives in full sun and requires only moderate watering.
Verbena Bonariensis
This beautiful plant produces slender, tall flower stems with small purple flowers from June through to October. Verbena Bonariensis is a staple in sunny spots—it thrives in full sun and can withstand dry conditions. Bees and butterflies are also attracted to its pollen- and nectar-rich blooms.
Salad Leaves
Salad leaves are perfect for a sunny garden, growing fast and thriving in smaller spaces like containers or empty garden borders. However, too much baking sun can turn them bitter. If temperatures are very high, move pots and containers to a shadier spot.
Mediterranean Herbs
Rosemary, thyme, oregano, and sage all thrive in a sunny garden. Intense sunlight maximises their flavours and beautiful aromas. These herbs are drought-tolerant and do well in nutrient-poor soil, making them ideal for an easy-care, sunny garden.
