How to create a drought-tolerant garden: Plants, tricks & tips
Lee Burkhill: Award Winning Designer & BBC 1's Garden Rescue Presenters Official Blog
With extreme weather now a common occurrence in our gardens, designing with plants for droughts or heat waves is on every gardeners mind. Rather than fighting against the rise in droughts or heat waves, planning a garden around it can be far better for the environment and help you stress less about your garden. This article will help guide you through the smart choices you have for a robust garden that doesn't reply on rainfall or additional maintenance with the weather.
Quick Answer
The best drought-tolerant plants for UK gardens are Mediterranean species such as lavender, rosemary, and sage alongside tough perennials like achillea, eryngium, and salvia. Once established, these plants need little or no supplementary watering and will thrive through hosepipe bans and long dry spells. Choose plants with silver or grey foliage, waxy leaves, or fleshy stems: all three are nature’s signals that a plant is built to handle drought.

With increasing concerns about water scarcity and the need for sustainable gardening practices, creating a drought-tolerant garden has become more crucial than ever. A drought-tolerant garden helps conserve water and offers a beautiful and resilient oasis in dry conditions. Whether we like it or not, the weather is changing along with global warming. Rainfall can be sporadic, plants are coming up earlier or later than ever each year, and the seasons are less predictable in terms of climate.

This article will explore effective strategies and practical tips for designing and maintaining a garden that thrives with minimal water requirements. By incorporating these techniques, you can transform your outdoor space into a sustainable haven that blooms even during the most challenging droughts.

Why drought-tolerant gardening matters in the UK
A Thompson and Morgan survey from 2025 found that over half of UK gardeners, 54%, now prioritise low-maintenance and drought-tolerant plants when making purchasing decisions. That figure tells you everything about how quickly the conversation has shifted. South-east England now receives less than 600mm of rain annually, with the driest months coinciding with peak growing season. Hosepipe bans are no longer rare events. They are a predictable part of the British summer calendar for many parts of the country.
I have designed gardens for over 20 years, and the questions I get asked most frequently have changed. Clients used to ask which plants had the most flowers. Now they ask which plants will survive a fortnight without rain while they are on holiday. Choosing drought-tolerant plants is not a compromise. It is the single most effective thing you can do to reduce garden maintenance and water bills simultaneously. The right plant in the right place will simply get on with it, rain or shine.

How to identify drought-tolerant plants
One of the most useful skills you can develop as a gardener is being able to spot a drought-tolerant plant at a glance, without needing to read the label. Plants have evolved extremely clever physical adaptations to cope with water stress, and once you know what to look for, you can make informed choices simply by looking at the foliage.
Silver or grey foliage is the most reliable signal. Plants like artemisia, lavender, and stachys have light-coloured leaves that reflect sunlight and reduce water loss through the leaf surface. If a plant is silver-leaved, it almost certainly handles drought. Waxy or leathery leaves create a waterproof coating that minimises evaporation. Rosemary, bay, and many evergreen shrubs use this approach. Fleshy or succulent leaves store water internally, allowing the plant to draw on reserves during dry spells. Sedum, sempervivum, and echeveria all work this way. Finally, deep root systems allow plants like ornamental grasses and prairie perennials to access moisture that shallow-rooted plants simply cannot reach, often drawing water from 60 to 90cm below the surface.
💡 Top Tip
When buying plants for a dry garden, avoid anything with large, lush, dark-green leaves. Big leafy plants transpire water rapidly and will need constant watering to survive a dry spell. Small, silver, waxy, or aromatic leaves are what you are looking for.
1. Choosing the right drought-tolerant plants
The foundation of a drought-tolerant garden lies in selecting the right plants that can withstand extended periods of dryness. By choosing plants that can cope with drought once established, you can save yourself the headache of needing irrigation, rain capture or extended periods of stress trying to water your plants and keep them hydrated.
My first tip is to look for native species of dry soil-loving plants, as they have evolved to thrive in your region’s specific climate conditions. These plants are naturally adapted to the available water resources, making them more drought-resistant.

Drought tolerant herbaceous plants
You will be amazed at just how many amazing plant types there are that will handle both drought and also dry shade in the garden. A drought-tolerant garden does not need to be a barren desert of spiky plants or cacti. There are plenty of flowering specimens to choose from.
Alongside the examples of drought-tolerant plants below, we also have an array of Mediterranean plants that are used to extended periods of dry hot weather, such as Lavender, Rosemary, and Sage, which are renowned for their ability to endure dry spells.
Lavenders (Lavandula)
Lavenders are Mediterranean plants that love both full sun and free-draining soil, making them excellent specimens for a drought garden. Their oily leaves are primed for heat waves and prevent too much moisture loss. They will also survive our English winters, provided they do not get waterlogged or experience frost below 5°C. English Lavender is hardier than French Lavender but does not flower as profusely. I have used lavender as pathway edging in dozens of client gardens and it never disappoints, rewarding every passer-by with a brush of fragrance in summer.

Mugwort (Artemisia)
Artemisia is a hidden secret in the garden design world, not often seen in garden centres and I am not entirely sure why. It is an edible herbaceous sub-shrub with wonderful silvery to white leaves that immediately signal drought-tolerance. Its flowers are tiny and not that noticeable, but the plant creates a lovely 1 to 1.5m tall and wide structure to give substance to a border. The aromatic leaves are great in cocktails or dried, and they may lose their leaves in cold winters but grow back reliably each year.

Molinia caerulea
This small mound-forming grass is pretty much indestructible and the flowers come in colours from green to dark purple. Once Molinia is established, it never needs watering. Even in months of drought, mine have always looked fantastic and required no attention whatsoever. The thin green leaves give great texture to a garden, followed by light airy seedheads that wave in the late summer breeze. Pruning Molinia grasses is super easy: cut back to the ground in late winter and that is it. No need to feed or fuss with these wonderful drought-tolerant grasses.

Lady’s Mantle (Alchemilla mollis)
Alchemilla mollis or Lady’s Mantle is a bulletproof plant that requires very little attention. It makes the top 10 of most plant groups across my site for the very reason that it fills out a border quickly, self-seeds everywhere, and is drought-tolerant once established. Its light green fan-like serrated leaves can pool the morning dew into beads that give it the name alchemilla or alchemy. Once you plant an Alchemilla you will end up always having Alchemilla, as it is so easy to self-seed and keep. Great for beginner or time-poor gardeners with dry gardens.

🛒 Buy alchemilla mollis from Amazon UK
Sea Holly (Eryngium)
Sea Holly or Eryngium is an arresting architectural herbaceous perennial plant. Its spiky flowers and sharply serrated leaves are not to be messed with. This coastal plant comes in colours from bright blue to silver, a really cool customer. Slugs and snails avoid it and it will cope in the hottest of heat waves, being used to living in dry sand dunes and battered by salty sea air. Its long tap root ventures deep into the soil in search of moisture, which is precisely why it laughs at a hosepipe ban.

🛒 Buy eryngium sea holly from Amazon UK
Blue Oat Grass (Helichtotrichon sempervirens)
Another grass that can cope when we turn up the heat is Blue Oat Grass. This steely blue grass is semi-evergreen, meaning in milder climates it keeps its colour all year round. It is one of the only genuinely blue grasses to hold its form through winter, which makes it extremely useful for year-round structure in a dry garden. Another coastal plant, it will cope with dry periods once established, and even when damaged by excess heat it can be cut back to regenerate the following year.

🛒 Buy blue oat grass from Amazon UK
Fennel (Foeniculum vulgare)
Fennel, the trusty aromatic liquorice-tasting herb, is also a wonderfully tough herbaceous perennial for garden borders. Like Lady’s Mantle, once you have it in your garden it self-seeds everywhere. Partial to growing in gravel in the most inhospitable places in full sun, this is a plant you need if your garden suffers from drought. The bronze variety in particular adds a stunning dark contrast to silver-leaved companions like artemisia and lavender.

Hyssop (Hyssopus officinalis)
Hyssop is a compact, semi-evergreen sub-shrub and a remarkable drought-tolerant plant that is often overlooked in UK garden centres. It loves being positioned in full sun and baked all summer long, and is also fantastic for bees. It rewards you with spikes of blue, purple, or pink flowers which are whorled, two-lipped, and tubular. It is these uniquely shaped flowers which will bring all the honey bees and pollinating insects to your garden. In milder climates it keeps its structure throughout winter, giving it genuine year-round value.

🛒 Buy hyssop plants from Amazon UK
Bearded Iris (Iris germanica)
If you are looking for something showy then look no further than the spectacular Bearded Iris, which loves to have its rhizome baked above ground. That is the bulge you see sticking out just above the soil surface. These plants hate being disturbed so once you plant them, leave them alone for a few years where they will happily multiply. Make sure the rhizome is not buried and gets full sun. That is how you get the most prolific blooms. Every 4 to 5 years you can lift and divide the iris with a sharp spade then replant to propagate these beautiful specimens for free.

🛒 Buy bearded iris from Amazon UK
Pinks (Dianthus)
Pinks are one of my favourite retro garden flowers as they remind me of my grandad and his front garden. Dianthus, commonly called pinks, have a bluey-grey stem and usually bright pink flowers. Once established, they require no feeding, no real attention, and make great cut flowers. The flowers have a very pungent clove-like scent, and they love to grow in full sun. Many years back, they were a favourite of the rockery garden and are easy to divide to propagate. That is precisely why they were found in everyone’s gardens back in the 1970s here in the UK.

🛒 Buy dianthus pinks from Amazon UK
Fleabane (Erigeron karvinskianus)
These little beauties are picture-perfect tiny daisies that will grow anywhere. Erigeron or Fleabane used to be part of the Old World asters and the true daisy family but now live in the Erigeron genus. Super easy to grow from seed if you have a greenhouse, these plants will colonise anywhere and everywhere in full sun. They seed in gravel gardens, sunny borders, and poor drought-weathered soil. My advice is to buy a few and then let them self-seed everywhere so they fill the gaps that other plants cannot.

🛒 Buy erigeron fleabane from Amazon UK
Rosemary (Salvia rosmarinus)
It is no surprise that like lavender, other Mediterranean plants such as Rosemary are also drought tolerant. They are native to warmer climates and have a number of clever tricks up their sleeve meaning they require little to no watering once established. Rosemary is an evergreen shrub with a number of defences against drought and hot weather. The first is that the leaves are rolled under to reduce transpiration, and the second is that the plant’s leaves are oily, helping to conserve even more water. Rosemary likes free-draining soil and full sun. The hotter the better.

🛒 Buy rosemary plants from Amazon UK
Sage (Salvia officinalis)
Sage is another fantastic drought-tolerant plant that can also be eaten. This easy-to-grow herb can be bought from supermarkets in pots as a living herb and then planted out in the sunniest parts of your garden. The aromatic leaves smell delicious when crushed and can be used in salads and cooking. Sage should be treated as an annual in colder parts of the UK, as severe winters and frost will kill it off. Alternatively, you can overwinter plants in a greenhouse or cold frame.

More drought-tolerant perennials worth knowing
The plants above are a solid foundation for any drought-tolerant garden, but there are several more perennials that competitors consistently recommend and that I have used successfully in my own garden designs. These are the plants that fill the spaces between your key specimens and keep the garden looking alive and interesting from late spring right through to the first frosts.
Hardy Salvia (Salvia nemorosa)
Hardy salvias are among the hardest-working plants in a dry garden. They flower prolifically from early summer into autumn, tolerate neglect with remarkable good humour, and attract bees and butterflies in huge numbers. Salvia nemorosa ‘Caradonna’ in particular is one I return to again and again in my garden designs, with its upright purple-black stems and vivid violet-blue flowers. Cut it back hard after the first flush and it will flower again. Salvias want full sun and free-draining soil and will sulk in heavy clay or shade, but give them those conditions and they are very nearly unkillable.

🛒 Buy hardy salvia from Amazon UK
Yarrow (Achillea millefolium)
Achillea, or yarrow, is a plant that drought-tolerant gardeners simply cannot do without. Its flat-topped flower heads come in an extraordinary range of colours from creamy white and soft yellow through to terracotta, deep red, and cerise pink. It flowers from June right through to September, provides exceptional structure in a border even when not in bloom, and develops a deep root system that accesses moisture other plants simply cannot reach. I have grown Achillea in some of the most baked, poor-soiled conditions imaginable, and it has never let me down. The dried seedheads provide interest well into winter.

🛒 Buy achillea yarrow plants from Amazon UK
Verbena bonariensis
Verbena bonariensis is one of those plants that earns its place in practically every garden I design. The tall, wiry stems carry clusters of tiny purple flowers from July right through to the first hard frosts, and the whole plant is transparent enough to sit in front of other plants without blocking them. Bees and butterflies absolutely adore it. It tolerates drought well once established, requires no staking despite reaching 1.5m, and self-seeds so freely that you will only ever need to buy it once. The only thing it dislikes is waterlogged soil in winter.

🛒 Buy verbena bonariensis from Amazon UK
Agapanthus (Agapanthus africanus)
Agapanthus, or African lily, is one of the most striking plants you can grow in a sunny border or large container, and it is far more drought-tolerant than its exotic looks might suggest. Originally from South Africa, it produces bold spherical flower heads in shades of deep blue, violet, and white on tall stems above its strap-like leaves. It needs watering in its first season to establish, but once its root system is in place it becomes remarkably self-sufficient through dry spells. In colder parts of the UK, it is best grown in a pot that can be moved under glass in winter.

🛒 Buy agapanthus plants from Amazon UK
Golden Oat Grass (Stipa gigantea)
Stipa gigantea, or golden oat grass, is one of the most architecturally impressive grasses you can grow in a UK garden. It forms a basal evergreen clump of fine, dark-green leaves, but what makes it unmistakable is the extraordinary display of tall, airy, golden-bronze oat-like seedheads that appear in early summer and persist through autumn, catching the light beautifully on warm evenings. It is deeply drought-tolerant once established and sends roots down to considerable depth in search of water. Plant it where the low evening sun can light up the seedheads from behind.

🛒 Buy stipa gigantea from Amazon UK
Hardy Geranium (Geranium spp.)
Hardy geraniums, or cranesbills, are without question one of the most reliable and adaptable groups of plants available to UK gardeners. They are amazingly floriferous, unfussy on soil conditions, drought-tolerant once established, excellent as ground cover, attractive to bees, and genuinely pest-resistant. Geranium ‘Rozanne’ is among my favourites, flowering from June right through to October in shades of violet-blue. Geranium macrorrhizum handles both drought and shade, making it particularly useful for difficult corners. Cut them back after the first flush for a second wave of flowers later in the season.

🛒 Buy hardy geranium plants from Amazon UK
Russian Sage (Perovskia atriplicifolia)
Russian sage is a plant that photographs beautifully, performs brilliantly in dry conditions, and is almost completely ignored in mainstream UK garden centres. That is a shame, because it is genuinely one of the best drought-tolerant shrubby perennials available. The silver-white stems carry clouds of tiny lavender-blue flowers from July to September, creating a hazy, billowing effect that looks spectacular combined with ornamental grasses, salvia, and achillea. It has all the hallmarks of a drought-tolerant plant: silver stems, deeply aromatic foliage, and Mediterranean origins. Cut back hard to the base in early spring each year.

🛒 Buy Russian sage perovskia from Amazon UK
Drought-tolerant succulents for gardens
Succulents and cacti can also be a wise choice for super hot gardens, especially in warmer countries where dry arid conditions are commonplace. In the UK, succulents usually are fine, but cacti can struggle unless under glass or covered from heavy rain. Cacti hate having soggy roots and will quickly keel over in boggy clay-like soil. Succulents are far better adapted for the occasional damp period, though.
Consider succulents and cacti, which store water in their leaves or stems, minimising moisture loss. In heat waves, they already have enough moisture to survive, unlike plants that transpire water quickly such as cut flowers and other ornamentals. Heavy winter frost is the biggest killer of both succulents and cacti, so unless you live somewhere with temperate, mild winters, always move these two genera under cover for the winter, such as in a conservatory or greenhouse.

Sedum (Stonecrop)
Sedum is a fantastic low-growing ground cover succulent that can cope with both extremes and high temperatures. A staple plant that will grow where many plants simply will not. Once established this plant seeds and spreads itself into every nook and cranny. Often used on green roof installations given how tough it is, sedum is great to help cover open ground and suppress weeds. It also provides nectar for late-season pollinators when many other plants have finished flowering.

🛒 Buy sedum stonecrop from Amazon UK
Hylotelephium telephium ‘Herbstfreude’ (Sedum ‘Autumn Joy’)
The classic border sedum has recently been reclassified to the Hylotelephium genus. This autumn-flowering succulent brings a blast of pink colour to the garden in September and October when other plants have gone over. Other than watering to establish, it thrives on neglect and can bulk up to make a lovely tall plant once it has been around for five to ten years in the same spot. In mild winters it keeps its leaves but can survive frost by losing its leaves and reemerging the following year. Great for bees visiting the garden late in the season.

🛒 Buy hylotelephium autumn joy from Amazon UK
Euphorbia characias
For a touch of the exotic that is both hardy and arresting, choose Euphorbia characias. A large species in the Euphorbia family, known for its acid green and bright yellow alien-like flowers. These plants are super tough in both droughts and extremes of weather and add a bright pop to any garden. Care should be taken when pruning, though, as the sap is a skin irritant, so always wear gloves and avoid touching your face. The statuesque form and year-round structural presence make it one of the most design-useful drought-tolerant plants available.

Drought-tolerant shrubs for structure and year-round interest
A drought-tolerant planting scheme needs structural plants, not just herbaceous perennials. Evergreen and deciduous shrubs provide the backbone of the garden through winter when perennials have died back, and many of the best drought-tolerant shrubs are among the most architectural and visually striking plants available. Here are the shrubs I reach for most often in dry garden designs.
Rock Rose (Cistus spp.)
Cistus or rock rose is one of the most reliably drought-tolerant evergreen shrubs available to UK gardeners. Native to the Mediterranean and Middle East, it produces an almost continuous display of papery, rose-like flowers from late spring through to midsummer, in white, pink, or magenta, often with a contrasting boss of golden stamens at the centre. Cistus thrives on neglect in poor, dry, alkaline soil and will actively resent being overfed or overwatered. Give it a warm, sheltered spot with sharp drainage and it will reward you for years. It dislikes being hard-pruned, so deadhead lightly and resist the urge to cut back heavily.

🛒 Buy cistus rock rose from Amazon UK
Yucca (Yucca gloriosa)
Yucca is genuinely one of the most dramatic and drought-tolerant plants you can grow in a UK garden, and it is remarkably hardier than its exotic appearance suggests. Yucca gloriosa forms a bold rosette of stiff, sword-like leaves and, once mature, produces a spectacular spike of creamy white bell-shaped flowers that can reach 2m tall in midsummer. It requires no supplementary watering once established and positively thrives in hot, dry, exposed positions. The only real management required is removing the spent flower spike. Do wear thick gloves when working around it, as the leaf tips are needle-sharp.

💡 Top Tip
When planting any drought-tolerant shrub or perennial, water it thoroughly for the first growing season. Drought tolerance kicks in once the root system is established. The most common mistake is planting a drought-tolerant plant and then not watering it at all in its first summer. Give it a good start and it will look after itself thereafter.
2. Efficient irrigation techniques for drought gardens
After choosing drought-tolerant plants, the next thing to consider is efficient irrigation for new gardens or newly planted flower beds.
To ensure your garden receives the necessary water whilst minimising waste, implementing efficient irrigation techniques is essential. This is especially so when you are planting up a new garden and the plants need help establishing their root system.
When I install irrigation in my garden designs it is only ever temporary. I would never design a garden that needed year-round irrigation, as it is incredibly wasteful. It also shows that the wrong plants have been chosen if they need year-round babysitting to survive.

However, for a new garden, a temporary seep hose or drip irrigation is best to get the plants started and make the most efficient use of precious water.
Drip irrigation systems are highly recommended for drought-tolerant gardens. They deliver water directly to the plant’s root zone, reducing evaporation and runoff. The same applies to a seep hose which seeps water out slowly so plants can take it up, rather than a sprinkler which is vastly inefficient and wastes water. Make sure you install a timer or moisture sensor to automate watering schedules and prevent overwatering.
Mulching is another valuable technique when dealing with dry or drought-ridden gardens. A mulch is a layer of organic matter, usually compost or bark, to help retain existing moisture. Applying a layer of organic mulch around plants helps retain moisture, suppress weeds, and moderate soil temperature. The best materials to use for a garden mulch are peat-free compost, wood chips, or gravel to cover the soil surface, ensuring the roots stay cool and moist.
3. Soil preparation and conservation for dry gardens
Preparing your garden’s soil is crucial for creating a drought-tolerant environment. If you have poor soil that is low in nutrients and struggles to retain moisture, any new plants you put in will struggle to establish. It is always better to improve your soil before planting even in a drought garden.
Work organic matter, such as compost or well-rotted manure, into the soil before planting. This improves soil structure, increases water-holding capacity, and promotes root development. Leaf mould is also an excellent soil improver and is easy to make at home in the autumn with fallen leaves. Furthermore, implement soil conservation practices to minimise moisture loss. Apply a layer of organic mulch to reduce evaporation and slow down weed growth. Consider using cover crops during periods of non-use, as they help prevent soil erosion and improve soil fertility.

💡 Top Tip
One of the most common mistakes with drought-tolerant plants is actually improving the soil too much. Rich, fertile, moisture-retentive soil encourages soft, lush growth that is more vulnerable to drought and frost. Mediterranean plants in particular prefer lean conditions. Improve drainage, but do not over-feed.
4. Water-smart garden design
When it comes to planning a drought garden, let us consider the layout of your plants and how you can group them to reduce watering. Microclimates and en-masse planting can work strongly in your favour. The top tips for a water-smart garden are: group plants with similar water requirements together to create microclimates; use water capture methods like water butts or soakaways; and make use of natural shade from trees for plants less tolerant to heat.

Clustering plants with taller species in the centre and shorter ones around the edges creates a natural windbreak, reducing evaporation caused by strong winds. Install water butts on downpipes or a water catchment system in your garden to collect and store rainwater for garden use. Use this harvested water during dry spells, reducing the reliance on freshwater sources. A single 200-litre water butt connected to a downpipe can collect enough rainfall in a typical UK spring to cover a significant proportion of your summer watering needs.
5. Hard landscaping and permeable options for paving
Consider hard landscaping features such as paths, patios, and rocks. These elements reduce the amount of lawn and planting beds, which typically require more water. By reducing your lawn you immediately reduce the watering required to keep the garden looking its best in the summer. It also means you can put in its place more drought-tolerant flower beds.
Replace some areas with permeable surfaces like gravel or permeable pavers, allowing rainwater to infiltrate the ground. Gravel is particularly useful in a drought garden as it also acts as a mulch, reducing evaporation from the soil surface while allowing rain to pass straight through to the root zone below. A gravel garden planted with drought-tolerant species is one of the lowest-maintenance garden styles possible and can look stunning from late spring to the first frosts.

Frequently asked questions about drought-tolerant plants
What are the most drought-tolerant plants for UK gardens?
The most drought-tolerant plants for UK gardens include lavender, rosemary, sage, eryngium (sea holly), achillea (yarrow), salvia, verbena bonariensis, erigeron, artemisia, agapanthus, stipa gigantea, sedum, and cistus. Mediterranean plants with silver or grey foliage, waxy leaves, or aromatic oils are almost universally drought-tolerant. Once established, these plants need little or no supplementary watering.
How do I know if a plant is drought-tolerant?
Look for silver or grey leaves, which reflect sunlight and reduce water loss. Waxy or leathery leaves create a waterproof barrier against evaporation. Fleshy, succulent leaves store water internally. Aromatic foliage often indicates Mediterranean origin, which almost always means drought-tolerance. Plants with deep tap roots or fine, grassy foliage also tend to handle dry conditions well. If a plant is native to the Mediterranean, South Africa, or a coastal environment, it is almost certainly drought-tolerant.
Do drought-tolerant plants need watering?
Yes, but only in their first growing season. All drought-tolerant plants need regular watering when first planted to help establish their root systems. Once those roots are in place, typically after the first full growing season, most drought-tolerant plants can cope with extended dry periods without supplementary watering. The most common mistake is planting a drought-tolerant plant and then not watering it at all in year one, which kills it before it has the chance to prove its resilience.
What soil is best for drought-tolerant plants?
Most drought-tolerant plants, particularly Mediterranean species, prefer free-draining soil rather than rich, fertile, moisture-retentive ground. Sandy or gritty soil is ideal. If your soil is heavy clay, improve drainage by incorporating grit, coarse sand, or fine gravel before planting. Raised beds and gravel gardens are excellent solutions for gardens with naturally poor drainage. Avoid adding too much rich compost or fertiliser, as this encourages soft, lush growth that is more vulnerable to drought.
Can I grow drought-tolerant plants in pots?
Yes, many drought-tolerant plants grow very well in containers, particularly agapanthus, sedum, sempervivum, lavender, rosemary, and yucca. Use a free-draining compost mixed with grit, ensure the pot has drainage holes, and raise it on feet to prevent waterlogging. Pots dry out faster than open ground, so even drought-tolerant plants in containers will need some watering during prolonged hot spells, though far less frequently than thirstier plants.
Which drought-tolerant plants are best for pollinators?
Many drought-tolerant plants are outstanding for bees and butterflies. Lavender, salvia, hyssop, erigeron, achillea, verbena bonariensis, agapanthus, and sedum are all pollinator favourites. The combination of drought-tolerance and pollinator value makes many of these plants an ideal choice for wildlife-friendly, low-water gardening. Planting a sequence of drought-tolerant species that flower from spring through to autumn will support pollinators throughout the entire season.
Are drought-tolerant plants suitable for coastal gardens?
Absolutely. Many drought-tolerant plants originate from coastal environments and are also salt-tolerant, making them excellent choices for seaside gardens. Eryngium, erigeron, blue oat grass, stipa, cistus, and lavender all handle coastal exposure well. Their deep roots, waxy leaves, or silver foliage evolved partly as a response to the harsh, exposed conditions found on coastlines, making them naturally well-suited to the British seaside garden.
