Best Drought-Resistant Plants

Spring and summer droughts are becoming increasingly common across many parts of the UK. With temperatures rising and rainfall becoming less consistent, drought-resistant plants have never been more important to gardeners. A drought-tolerant garden can be more sustainable, saves you time and effort, and cuts back on the water bill. It’s also a great option if you’re away from home for long periods.

There are many garden plants that are well adapted to dry conditions, thriving on little water even in hot, sunny weather. Like all plants they will require watering for their first season after planting – make sure to install a water butt to collect rainwater if you don’t have one already! – but once established, these drought-resistant plants will pretty much look after themselves. Here we’ll take you through some of the best drought-tolerant plants to use for a garden that will look fantastic but let you leave the sprinkler in the shed.

There’s a place for salvias in every garden. They can be one of the most long-flowering of all perennials, are loved by pollinators, and come in an almost endless array of colours, sizes and flower shapes. On top of that, they thrive in dry conditions! For flowering duration there’s no beating the award-winning Salvia ‘Amistad’, a border hero that sends up spires of deep purple blooms continuously from June right through to November. For containers or smaller spaces, try the compact Salvia ‘Salvatore Deep Blue’, which packs a punch at only 35cm tall. If you’re looking to plant en masse, Salvia nemorosa ‘Caradonna’ is an ideal choice, providing low maintenance swathes of colour that will be abuzz with bees all summer long. Salvias don’t have to be purple, though! Try the pretty shell-pink Salvia ‘Dyson’s Joy’ for a pastel colour scheme, the elegant ‘Clotted Cream’ for a calming and refined white or ‘Hot Lips’ for adding a sizzling pop of colour to a hot border.


Low-maintenance, highly drought-tolerant and providing year-round interest with its attractive silvery foliage, lavender is an obvious choice for any dry, sunny spot. English lavender ‘Munstead’ is one of the best, producing masses of deep blue-purple heads on neat, compact plants. These are ideal for edging paths or borders or creating a low hedge.

Verbena bonariensis

Verbena bonariensis has become a key figure in dry borders and prairie planting schemes. Its slender, airy stems rise above other plants, creating height and texture. This reliable hardy perennial is incredibly easy to grow, requires little maintenance and will self-seed if allowed to create beautiful, naturalistic drifts.


Echinacea or coneflower is a hardworking perennial in any garden, providing valuable late summer colour with its nectar-rich blooms, standing up to dry conditions and needing little maintenance. It’s also a staple of prairie planting schemes. You can’t go wrong with the classic Echinacea purpurea, but if you’re looking for something a bit different, try the white version Echinacea purpurea ‘Alba’, the fiery bicolored red and yellow Echinacea ‘Parrot’, or the floriferous ‘Cheyenne Spirit’ in hot shades of red and orange for a superb addition to a hot border.


Grasses are some of the most useful drought-resistant plants of all. Image: Canva

Grasses are a staple of any low-maintenance, droughtproof garden. Stipa tenuissima is a fantastic choice: requiring very little water, it provides year-round interest, structure and movement to borders, whilst providing a matrix through which drought-tolerant herbaceous perennials such as salvias, verbena and echinacea can grow for a stunning combination. Pennisetum alopecuroides or fountain grass is a very decorative ornamental grass producing beautiful pink-tinged flowerheads like little squirrels’ tails. The tall, upright Calamagrostis x acutiflora ‘Karl Foerster’ has become very popular as a screening plant – a low-maintenance, airy alternative to a hedge.

Trees & Shrubs

A selection of drought-tolerant shrubs and small trees – rosemary, rock rose, olive and ceanothus.

A selection of well-placed trees and shrubs is key to creating structure, height and year-round interest in any garden or outdoor space. There are a variety of drought-resistant shrubs and small trees to choose from – with the bonus that many are evergreen!


Rosemary is a wonderfully hardworking shrub. As well as being drought-tolerant, it provides year-round interest, repeat flowers over a long period, and is a valuable culinary herb! Rosemary comes in different forms to suit different spaces. Upright shrub forms such as the lovely ‘Tuscan Blue’ are perfect for adding evergreen structure to borders, whilst prostrate or semi-trailing forms such as ‘Corsican’ look wonderful tumbling over a wall or in sun-drenched pots, hanging baskets or window boxes.

Rock rose

‘Rock rose’ is a name that is shared by two related but distinct groups of plants: Helianthemum and Cistus. Both are evergreen and thrive in free-draining and nutrient-poor soils, requiring plenty of sun and little water. Cistus grow into larger shrubs than the typically low-growing Helianthemum. For a good-size shrub (to 1m) consider Cistus x purpureus ‘Alan Fradd’, which bears lovely, large white flowers with yellow centres and an attractive splash of crimson to the base of each petal. Cistus x pulverulentus ‘Sunset’ is a great smaller shrub (to 60cm), producing deep rose-pink flowers all summer long. Though they are much smaller sub-shrubs, Helianthemum are too good to ignore, though: Helianthemum ‘Golden Queen’ forms neat, low clumps that become smothered in sunny golden yellow buttercup-shaped blooms from late spring to mid-summer. At only 20cm high, it is ideal for containers, rockeries and the front of borders.


Native to California, Ceanothus or Californian lilac knows a thing or two about heat and drought! This gorgeous evergreen shrub is perfect for adding height to a border or as a specimen plant. Larger varieties such as ‘Italian Skies’ can also be used as a small tree, developing an attractive bare trunk over time. In late spring or summer, the small, glossy deep green leaves become smothered in dense clusters of tiny blue flowers, which are an absolute magnet for bees.


Hailing from the Mediterranean, this elegant evergreen tree provides year-round interest with its narrow, silvery foliage. Our olive tree standard is ideal for patio pots and will happily overwinter outdoors in most parts of the UK providing it is in a sheltered spot; alternatively you can move it into a greenhouse or conservatory over winter.

Ground Cover

Thyme is another herb that is just as useful in the garden as it is in the kitchen. This mat-forming evergreen makes excellent dry ground cover as well as being a lovely addition to containers, rockeries and the front of borders. The pretty clusters of tiny flowers are also very attractive to pollinators. Thymus ‘Silver Posie’ is a particularly attractive variety, boasting a silver variegation to the leaf that intensifies in winter, making it a great addition to winter and spring container displays.


Forming a low, evergreen carpet, Lithodora is ideal for the front of borders, rockeries, gravel gardens and containers. Lithodora diffusa ‘Heavenly Blue’ is one of the best varieties, producing masses of vivid electric-blue flowers from late spring throughout summer.


Thriving in dry soils, walls and rockeries, this endlessly cheerful little daisy produces dainty white and pink flowers non-stop all spring, summer and autumn! It will readily self-seed to form a delightful carpet, making it ideal for ground cover. It also looks great as a gap-filler around taller plants in borders. Erigeron ‘Stallone’ is a floriferous variety with a lovely mix of white and pink flowers.


Surprisingly drought-tolerant once established, aubretia quickly spreads to form an evergreen mat which becomes smothered in four-petalled purple blooms throughout spring. As well as ground cover, it is perfect for rockeries, the front of borders and cascading over walls.

Best plants for low hedges

There are many situations that call for a low hedge. It could be a formal edging to a border or path, a way to divide up a small garden into separate areas without cramping the space, a structural backdrop to other planting or simply a way to separate your drive from your neighbour’s. The beauty of a low hedge is that it creates a divide whilst still maintaining an open and spacious feel.

Whilst the size of almost any hedge can be limited by how often and how hard you trim it, there are certain plants that lend themselves particularly well to low hedges without wearing out the hedgetrimmer. The ideal candidate is a compact, small-leafed evergreen shrub that is not too fast-growing. Here we’ve picked out some of the best plants for a low hedge – whether you’re looking something formal, informal, flowering or prickly, read on to find the best for you!


Buxus sempervirens is an absolutely classic low hedging plant and for good reason. A bushy habit with masses of small, densely packed deep green leaves makes box ideal for trimming into precise shapes and offsetting complex planting schemes. Box is often used to enclose formal beds, forming the backbone of parterres and knot gardens around the world. However, as almost anyone who has tried to maintain a pristine box hedge will know, it can suffer from blight and the increasingly common box caterpillar. If this is a risk you’d rather avoid, there are some great box alternatives out there – read on to discover some of the best.

Height: to 200cm (79in)
Type of hedge: formal
Great for: stepover hedges, topiary

Lonicera pileata

Lonicera pileata or box-leaved honeysuckle is one of the most convincing box lookalikes that can be used in many of the same situations, but won’t succumb to box blight or caterpillar. This tough, drought-tolerant evergreen will quickly fill out to form a dense, compact hedge, which can be easily kept to a desired shape and size by trimming in summer or autumn. The display is enhanced by creamy flowers in spring and purple berries in autumn.

Height: to 100cm (39in)
Type of hedge: formal
Great for: stepover hedges, topiary

A low-growing Euonymus such as ‘Emerald ‘n’ Gold’ is another great alternative to box without the risk of disease. ‘Emerald ‘n’ Gold’ is the variety of choice for edging small formal beds at renowned National Trust garden Hidcote Manor.

Height: to 60cm (24in)
Type of hedge: formal
Great for: stepover hedges, adding colour with variegated leaves

For a more informal hedge, Pittosporum tenuifolium ‘Tom Thumb’ is a great option for mild areas. Boasting attractive deep glossy purple foliage, ‘Tom Thumb’ forms a dense, rounded shrub that is ideal for a cloud-pruned hedge.

Height: to 100cm (39in)
Type of hedge: formal or informal
Great for: coastal gardens

Compact hebes such as ‘Red Edge’ make a great low hedge that requires virtually no maintenance. Year-round interest is provided by the small, pointed greyish-green leaves attractively edged with red. The display is enhanced in summer by conical clusters of pale lilac flowers, which are attractive to bees and butterflies.

Height: to 45cm (18in)
Type of hedge: informal, flowering
Great for: wildlife, low-maintenance gardens

Ilex crenata

Ilex crenata ‘Stokes’ is another great alternative to box for a low formal hedge, producing small, glossy dark green leaves with a gently scalloped edge. White flowers in May are followed by glossy black berries. Japanese holly is an extremely cold tolerant hedging plant that won’t scorch like box, while its compact habit and slow growth rate means it won’t need trimming very often.

Height: to 60cm (24in)
Type of hedge: formal
Great for: stepover hedges, topiary

Sarcococca confusa

This gorgeously scented winter-flowering evergreen makes a lovely informal or informal hedge, depending whether you allow it to take on its natural form or trim it into shape. Year-round interest is provided by the glossy deep green, spear-shaped leaves and shiny black berries, but the plant really excels in January when it fills the air with the most delicious, heady scent from its clusters of small cream flowers. This makes winter box the perfect plant for low hedges near paths, doorways and patios, where its fragrance can be enjoyed to the full.

Height: to 150cm (5ft)
Type of hedge: formal or informal, flowering, scented
Great for: wildlife, winter gardens

A row of lavender makes an attractive, drought-tolerant, fragrant divide that will attract bees and butterflies. Little maintenance is required other than a light shearing back after flowering to retain a compact shape and prevent legginess. Producing a haze of blue-purple flowers above attractive greyish evergreen foliage, lavenders such as ‘Munstead’ are a great low hedging choice for dry areas.

Height: to 45cm (18in)
Type of hedge: formal or informal, flowering, scented
Great for: wildlife, dry sites

This prickly hedging choice is ideal if you’re looking to discourage animals such as cats from passing through.

Type of hedge: informal, flowering
Great for: summer colour, deterring animals
