Typified by their sunny, well-drained conditions, gravel gardens are low-maintenance and require much less water than the average garden.
Given these growing requirements, it’s important to choose drought-tolerant plants. One of the world’s best known gravel gardens is that of Beth Chatto – bursting with life and colour, it has famously never been watered and relies solely on rain.
When choosing a site for a gravel garden, go for a sunny spot. That way you’ll be able to grow the sun-loving Mediterranean species that thrive in poor, dry conditions.
Consider the gravel colour and size you choose carefully. Self-binding gravels are comprised of varied stone sizes, so are ideal for creating a natural look.
Discover some of our favourite plants for a gravel garden.
Euphorbias are remarkably drought-tolerant, and different species can be used to perform different roles in a gravel garden. Euphorbia characias subsp. wulfenii is fantastic for providing shots of limey colour, while Euphorbia x pasteurii has sweetly scented blooms. Towards the front, try the sprawling Euphorbia myrsinites (pictured).
Catmints are a brilliant, pollinator-friendly addition to gravel gardens. For quick colour, try ‘Six Hills Giant’, which is hardy and vigorous. Nepeta x faassenii is a pretty choice for edging paths.
The airy stems of Verbena bonariensis are fantastic for the contrast they provide with other plants and the bright purple dots of colour from the flowers. Bees and butterflies love the blooms. Find out how to take cuttings from Verbena bonariensis.
Phlomis produce fantastic whorls of bee-friendly blooms at regular intervals on their stems. A brilliant architectural addition to the gravel garden, as it also provides winter interest in the form of pretty seedheads. For yellow flowers, grow Phlomis fruticosa (pictured) or Phlomis russeliana, and for icy pink blooms, try Phlomis tuberosa ‘Amazone’.
Most cistus are small evergreen shrubs, with a compact, domed shape and saucer-shaped flowers. They combine especially well with other Mediterranean plants like lavender and rosemary – both of which are at home in a gravel garden. Most cistus have white or pink flowers.
The silver, furry-leaved stachys like ‘Big Ears’ and ‘Silver Carpet’ are good for a number of reasons. They’re good for ground cover, provide flowers for pollinators and attract solitary wool carder bees, which use the ‘wool’ to line their nests. Another good gravel garden choice with furry leaves is Lychnis coronaria.
Lavender positively thrives in dry spots. For the the front of borders, try low-growing varieties like ‘Blue Cushion’ or ‘Nana Alba’. To fill larger gaps, go for ‘Grosso’ or ‘Sawyers’. Find out how to take lavender cuttings.
Evergreen grasses like Stipa gigantea and Stipa tenuissima are brilliant for the texture and movement they bring to planting schemes. As the name suggests, Stipa gigantea is much larger. They help plants with pompon flowers like alliums, echinops and eryngium to stand out – all of which are suited to a gravel garden.
Gauras are renowned for their drought-tolerance. They have a lovely relaxed quality about them, and tend to flower over a long period, starting in mid-spring and ending in autumn.
The key to growing agaves in the UK is keeping them dry over winter. In milder locations most can remain outdoors over winter, or move indoors in colder spots. They’re worth the effort, providing an unrivalled, exotic feel. Dasylirions and yuccas are other good picks for this role.
Leave space for seats
Don’t forget to leave some space to enjoy the fruits of your labour. A small, unplanted area will be enough for a bench or bistro set. Use garden lights to make the garden useable in the evening and enhance plants, particularly those with architectural leaves and stems. Try festoon lights or these glass jar lanterns.
