Gardeners in the UK are being urged to stop watering three specific plants during heatwaves, as experts highlight their natural drought tolerance and ability to thrive with little to no irrigation. With climate change driving more frequent hot spells and prolonged dry periods, many homeowners struggle to keep gardens alive, but selecting the right plants can reduce maintenance and water use.
Echinacea: A Hardy Perennial for Dry Conditions
Echinacea, also known as coneflower, is a favourite among gardeners seeking colourful blooms with minimal upkeep. Available in a variety of vibrant shades, this hardy perennial is highly tolerant of dry conditions and performs well in most soil types. Its large flower heads attract butterflies and pollinators throughout the summer, while its ability to self-seed means new plants appear year after year without extra cost or effort.
A gardening expert on TikTok, known as @viewfromthepottingbench, recommended echinacea as one of three plants that require no watering during a heatwave. "The next one is one of my absolute favourite plants," the expert said.
Lavender: A Mediterranean Classic for Sun and Heat
Lavender remains one of the most reliable choices for low-maintenance gardens. The fragrant Mediterranean shrub is renowned for its long flowering season, drought tolerance, and ability to attract bees and other pollinating insects. Calling it "an absolute classic," the gardening expert said lavender is "a must-have in every garden." Adapted to hot, dry climates, lavender thrives in full sun and well-drained soil, making it particularly well suited to heatwave conditions.
Agapanthus: Striking Blooms with Strong Roots
The final recommendation is agapanthus, a striking South African plant known for its tall stems topped with clusters of blue, purple, or white flowers. The gardening expert described it as the standout choice, praising its impressive root system and resilience during hot weather. "Whether you've got a small garden or a sprawling estate, this is a plant for you," he said, recommending gardeners plant several together and repeat them throughout the garden for the best visual impact. Because agapanthus develops strong root systems, it can also be divided and replanted over time, allowing gardeners to expand their displays with little additional expense.
These three plants offer a practical solution for UK gardeners facing increasingly hot summers. By choosing drought-tolerant varieties, homeowners can maintain vibrant gardens while conserving water and reducing the time spent on maintenance.
