8 drought-tolerant plants for front garden pots that barely need watering – experts say these low-maintenance picks will stay lush without the upkeep

While the warmer weather has been fabulous, keeping pots and planters well-watered has been a challenge. For me, the front garden has been particularly tricky, as it's in constant sun and I have lots of containers, so it’s got me thinking about what I can plant in front garden pots that won’t require too much watering.

Aside from the heat drying out container plants more quickly, one of the problems with front garden ideas is often access to water. I live in a terraced house, so there’s no outdoor tap at the front, which means me carrying hefty watering cans through the house, so choosing fairly drought-tolerant plants is key.

‘Containers and hanging baskets are usually the first to suffer in sudden heat because they dry out much faster than plants growing in the ground,’ says David Denyer, flower and garden expert at eflorist. ‘Newly planted flowers and young bedding plants can also struggle, as their roots are still fairly shallow and haven’t had time to properly establish themselves yet.’ But by timing your watering schedule right and choosing low-maintenance plants, you can still keep your front garden and containers looking vibrant in the heat.

1. Lavender

‘Lavender is one of the best all-round choices as it can withstand extreme heat and dry weather conditions,’ suggests David. ‘It will also produce flowers that are long-lasting and react nicely to being pruned, keeping a nice, neat shape. They’re also great at attracting bees.

To get the best out of your Lavender, I’d advise planting it in a large pot with free-draining compost, exposed to full sunlight.’

Shelley Davis, plant expert at Flying Flowers, agrees: ‘Native to the sun-drenched landscapes of the Mediterranean and Middle East, lavender has earned its place as a staple in English gardens for its incredible scent and effortless beauty. The trick to keeping it low-maintenance is mimicking its home climate with plenty of sunlight and very well-draining soil, like Miracle-Gro's premium compost, £5 from Amazon. When potting lavender, try mixing in some perlite (you can buy 10L for £8.79 from Amazon) or coarse sand to keep the soil loose.’

‘To avoid the dreaded root rot, the most common killer of potted lavender, only water when the soil feels dry an inch deep,’ adds Shelley. ‘Remember, this plant prefers a ‘soak and dry’ and an annual pruning approach over constant moisture and regular maintenance.’

• Gardeners Dream: Add fragrance and colour with this pretty French Lavender stoechas. from £16.99.

2. Rosemary

‘Rosemary is far more than just a kitchen staple,’ says Shelley. ‘It’s a rugged, woody herb that brings effortless beauty to any garden. Because it actually despises overwatering and handles the cold with ease, it is remarkably easy to keep alive. Like its Mediterranean cousin, lavender, rosemary craves sunlight and sandy, free-draining soil.

‘Potted rosemary trees (like these Rosemary Lollipop trees, £18.99 from B&Q) look fabulous either side of a front door, and planting rosemary near an entranceway doesn’t just give you a low-maintenance evergreen; it also greets your guests with a wonderful, fresh aroma every time they visit, so it is a great fragrant plant for a front porch.’

Where to buy rosemary plants:

• Amazon: Easy to grow, try these Gardeners Dream Rosemary Bush Plants, from £9.49.
• Crocus: Or try this pretty trailing Rosemary Blue Cascade 'Lowros', £21.99.

3. Olive trees

‘Like most Mediterranean-style plants, olive trees will handle the hot, dry weather no problem,’ says David. ‘They also look great in modern front gardens. I’d recommend placing them in a sunny spot, deep watering occasionally when they have established, and remember to keep them in a large container.’ These deep watering spikes, £7.99 at Amazon will help reduce evaporation loss and targeted hydration for potted plants.

'One of the biggest mistakes people make is watering little and often once the heat arrives,’ adds David. ‘While it feels like you’re helping, shallow watering can actually encourage weaker roots because the moisture never reaches deeper into the soil. A much better approach is to water thoroughly either early in the morning or later in the evening so plants can properly absorb what they need before the heat of the day.’

Where to buy olive trees:

4. Agave

‘For a dramatic, sculptural look that requires almost zero effort, agaves are the ultimate choice for potted gardens,’ says Shelley. ‘Known as ‘century plants’ because of the many years they take to bloom, these outdoor succulents are incredibly drought-tolerant. While the main plant dies after its rare flowering, it thoughtfully leaves behind shoots to take its place.’

‘For a thriving, statement-making plant, use a terracotta pot with a dedicated succulent potting mix (Westland's cacti and succulent potting mix is a great, budget buy, £5, Amazon) and only water when the soil is bone-dry.’

Where to buy agave plants:

• Gardening Express: Make a statement with this Agave Americana Variegata - American Aloe - Century Plant, £15.99.
• Dobies: Or try the subtle blue tones of this Dianella revoluta 'Blue Stream', from £14.99.

5. Geraniums

‘Geraniums will tolerate dry compost well, and when it comes to how often you should water in hot weather, geraniums can even cope with a few missed waterings,’ suggests David. ‘And their colour makes them a great addition in the summer. If you deadhead geraniums, you might be able to keep them blooming for months.’

‘When it comes to sunny front gardens, moisture-loving plants, like hydrangeas and ferns, are especially prone to drooping or scorching in sudden heat, particularly if they’re sitting in full afternoon sun. If possible, move vulnerable pots somewhere slightly more sheltered when it is going to be particularly hot, even if it’s just somewhere that avoids the hottest part of the afternoon.’

Where to buy geranium plants:

• Suttons: Buy these garden-ready Geranium 'Best Red' F1, from £4.99.
• Thompson & Morgan: Enjoy a blaze of bright colour with these Geranium 'Jackpot Candyfloss' Mix, from £12.99.

6. Sedums

‘Sedum, often called stonecrop, is a gardener’s dream because it truly is a plant that thrives on benign neglect,’ advises Shelley. ‘These hardy succulents require almost no pruning, feeding, or watering to look their best. In fact, once they are settled in an outdoor pot, they can usually survive on UK rainfall alone.’

‘With so many varieties to choose from, sedums are as stylish as they are easy. You can use trailing types like 'Burro's Tail' sedum, £21.99, from Amazon, a beautiful texture and colour, or choose upright varieties like ‘Autumn Joy’, £7.99 from Gardening Express, to create a stunning focal point that draws in pollinators late in the season.’

Where to buy sedum plants:

• Crocus: For pots or sun-drenched borders, try these Hylotelephium × mottramianum 'Herbstfreude' stonecrop, from £9.99.
• Gardeners Dream: Enjoy a variety of colours with this Sedum Mix, £20.99.

7. Salvia

‘Salvia copes far better with heat than many traditional bedding plants,’ suggests David. ‘Salvia is one of the best perennial plants for attracting pollinators like bees, moths and butterflies. And they also look great when paired with other Mediterranean-style plants like lavender.’

Choose a roomy pot with drainage holes at the bottom and fill it with multi-purpose compost with a little perlite or sand added for extra drainage. Standing the container on pot feet will also help with drainage.

Where to buy salvia plants:

• B&Q: For stunning purple colour in pots or borders, try these Salvia Love and Wishes 3 plug plants perennial plants, £11.99.
• Amazon: Or try this multicoloured selection - Salvia Vista Mixed, £13.59.

8. Phormium

‘Phormium is perfect if you want a low-maintenance option for front gardens,’ suggests David. ‘They have a great contemporary look which lasts all year round, and the foliage will cope well come wind, sun, or dry spells.’

Ensure you choose a large enough container to accommodate the growing size of your plant (check the plant label for height and spread). A plant 1.5m tall will usually need a container at least 50cm wide and the same deep. And ensure the container is weighty enough not to topple over. Alternatively, try phormium in a front garden border or raised bed for a striking look.

Where to buy phormium plants:

• Gardeners Dream: Add wow with this dramatic dark-toned Phormium 'Bronze Baby' from £11.90 each.
• Primrose: With arching, sword-shapes leaves and a pink-toned leaves, try this Phormium Sundowner | New Zealand Flax, £38.99.
