Not everyone has time to water their garden every day in summer. Between holidays, weekend trips, and long evenings away from home, the watering can often gets left behind. The good news? These seven plants genuinely don't mind — and some of them actually prefer it that way.
1. Daylily – stunning and surprisingly tough
Daylilies are a gardener's best friend for good reason. Their long, arching leaves and vibrant blooms last for weeks, and they hold up beautifully even when watering is irregular. They're not fussy about soil type or light conditions either, which means they'll thrive in almost any garden without much fuss. If you want reliable colour with minimal effort, daylilies deliver.
2. Lavender – the fragrant survivor
Lavender doesn't just tolerate heat and drought — it genuinely loves them. Native to the sun-baked hillsides of the Mediterranean, this aromatic plant thrives in full sun and dry conditions that would stress most other plants. Once it's established in your garden, it asks for almost nothing in return and rewards you with weeks of fragrant purple blooms. Forget to water it? It'll thank you for it.
3. Thyme – a kitchen hero that earns its place in the garden too
Thyme is one of those rare plants that works just as hard outdoors as it does in your cooking. Its compact, aromatic foliage looks wonderful along garden borders or tucked between rocks, and it handles sunny, warm spots with ease. It needs very little water and practically looks after itself through summer. Harvest a few sprigs for dinner and let the rest get on with it.
4. Rosemary – a Mediterranean classic that loves to be left alone
Rosemary is built for heat. As a true Mediterranean plant, it thrives in dry, nutrient-poor soil and barely notices when watering is skipped. Its silvery-green needles bring a beautiful, sun-drenched atmosphere to any garden, and of course, it's endlessly useful in the kitchen too. Neglect it a little and it will reward you all the more.
Looking to create a low-maintenance garden that looks great all season? These cottage-style garden ideas are a great place to start.
5. Sedum – the drought-tolerant showstopper
Sedums are among the most striking succulents you can grow in a garden, and their extremely low water needs make them one of the most practical choices for summer. Whether you choose a ground-covering variety or a taller, upright type, sedums hold their colour and structure even through the hottest weeks of the year. They're nearly impossible to neglect to death.
6. Yarrow – the wildflower that never gives up
Yarrow brings a relaxed, wildflower charm to garden beds while being one of the toughest perennials you can plant. It blooms for a long time, handles full sun without complaint, and asks for almost no watering once it's settled in. It suits a wide range of garden styles and looks effortlessly natural whether planted in drifts or mixed borders.
7. Sage – beautiful, aromatic, and low-maintenance
Sage earns its place in any summer garden with its distinctive silvery leaves and eye-catching flower spikes. Its low water requirements make it ideal for gardeners who want beauty without daily commitment. It doubles up as a culinary herb and a calming tea, so you get both looks and practicality from a single plant.
The common thread running through all of these plants is simple: they've evolved to handle heat, dry spells, and a little neglect. Choosing drought-tolerant plants doesn't mean settling for a dull garden — it means spending less time worrying and more time enjoying it. Fill your borders with these seven and your garden will look after itself, even on the busiest summer days.
