Ground cover plants are naturally low-growing plants that form attractive mounds or carpets. They cover the ground quickly, covering bare soil. They are often low-maintenance and often evergreen.
Ground cover plants are used to fill in gaps at the front of a border, as well as those tricky spots at the bases of shrubs that are difficult to plant. They can also help cover the bare 'legs' of roses, complementing their flowers. Ground cover plants are also great for covering tricky sites, such as slopes, which are difficult to access and plant. Some can also be grown as an alternative to a lawn.
As they cover the soil, ground cover plants are great for suppressing weeds. They act like a mulch, so they can help to lock in soil moisture and nutrients. Some can even help with soil erosion on slopes, their roots holding everything together when it rains.
When choosing ground cover plants, choose varieties that suit the soil and aspect of your garden. Weed the area thoroughly before you plant, as it will be difficult to remove weeds once the plants are in.
There are many types of ground cover plant, grown for their evergreen foliage or flowers, and sometimes both. Here are 20 of the best.
Hardy geraniums are incredibly versatile plants, as they thrive in sun or shade and in most soil types. They look good in almost all styles of planting, from cottage gardens to a more contemporary schemes. They're great for growing at the front of the border and under shrubs and roses. They come in a wide range of colours, from white to pink and blue. They're not evergreen, so their foliage dies back in winter, but they flower for months, from late spring to early autumn, and are popular with bees. One of the best hardy geraniums is Geranium 'Rozanne' ('Gerwat') – its vivid blue flowers light up the garden for months on end in summer.

'Flower Carpet' roses
'Flower Carpet' roses are a group of roses that are grown as ground cover, creating a carpet of flowers, as their name suggests. They have semi-double flowers and semi-evergreen foliage. They can be used as an unusual addition to the front of the border, or for covering a slope. They come in a range of colours, including white, coral, pink and red. They need a sheltered, sunny spot and well-drained soil.

Bright clumps of aubretias – mostly in shades of blue and purple, but also red or pink – are a sign that spring has arrived. They thrive on well drained soil (they especially like alkaline soil) in full sun, and are ideal for growing along the top of walls, where they can spill over the edge, or on a stony slope. They are also great for gravel gardens and rockeries. Cut back after flowering and they may reward you with a second flush in summer. Aubretias aren't evergreen so will die back in winter.

If you have a large area to cover quickly, especially one that is on poor soil or is tricky to plant, why not consider a wildflower meadow? There are many seed mixes available, for all kinds of soils and aspects, with either a mix of annuals, perennials or both. You can also buy ready-sown wildflower turf, which you lay over a prepared area as you would a carpet. The palette will develop as the seasons change, and the flowers are, of course, fantastic for wildlife. Meadows are relatively low maintenance, just requiring a cut or two a year. You could even consider replacing all or part of your lawn with a wildflower meadow – this is especially useful if part of your lawn which is tricky to mow – on a slope, for example.

Low growing, spreading herbs are perfect for covering the ground or replacing an area of lawn, and have the added bonus of providing delicious flavour for cooking. Their flowers are incredibly popular with bees, too. In a sunny spot, try thyme, oregano, camomile, or prostrate rosemary, which is evergreen and has bright blue flowers in early spring. It also has deep roots and can therefore help with soil erosion on a sloping site. In a shady spot, try sweet woodruff (Galium odoratum) which is good for growing under inhospitable spots under trees, bearing starry, white flowers in spring. It is also known as the hay plant, as its flowers and leaves smell of hay and can be dried for use in pot pourri or as an insect repellent. Or try wintergreen, Gaultheria procumbens, a low growing, evergreen shrub with minty leaves that be dried and made into a tea. It bears red berries in winter and likes acidic soil.

Mexican daisy, Erigeron karviskianus
Erigeron karviskianus, Mexican daisy or fleabane, may hail from Mexico but it is more than happy spreading in sunny gardens in the UK, where it will grow at the front of a border, creep down the sides of stone or brick steps, tuck itself into wall crevices and establish between paving slabs. It spreads slowly via its roots and also self seeds. It flowers from May to November and is very low maintenance. The daisy-like flowers often become pink with age, and different shades of flower will be found on one plant.
