Ground cover plants offer a host of benefits in the garden, but perhaps most important is their ability to suppress weed growth. But what are the best ground cover plants to prevent weeds?
From flowering varieties to evergreen stalwarts, there are options for all garden ideas – and besides knowing how to trim ground cover plants, you'll be able to enjoy attractive, low-maintenance borders.
‘Ground cover plants form a dense mat over the soil by spreading low,’ says Jane Dobbs, Team Lead for Gardening at Allan’s Gardeners. ‘Gardeners love these plants because they prevent weeds, reduce soil erosion, and make gardens look great.’
We asked the experts for their top picks for the best ground cover plants to prevent weeds.
1. Bugleweed
First on the list of best ground cover plants to prevent weeds is bugleweed.
'Also known as Ajuga, bugleweed is a fast-spreading ground cover with attractive foliage and blue flower spikes,' says Jane from Allan's Gardeners. 'Sun and partial shade are both suitable for it.'
There are a couple of factors to consider before planting. 'Bugle requires moisture so it doesn't always do well beneath trees and shrubs as the ground can be too rooty and dry,' says Annelise, horticultural expert for Thompson & Morgan. 'In moist conditions, Ajuga spreads rapidly, creating a loose mat of creeping stolons. Simply cut off sections and replant them to spread it around the garden.'

- Gardening Express: Stave off weeds with this range of bugle plants.
2. Creeping thyme
Creeping thyme is an attractive feature to consider when brainstorming garden border ideas, so we're glad to see it make the list of the best ground cover plants to prevent weeds.
'With its small purple flowers and fragrant leaves, creeping thyme is a low-growing perennial,' says Jane from Allan's Gardeners. 'Well-drained soil and sunshine are best for this plant.'
Creeping thyme is also a popular low-maintenance lawn alternative, and it's drought-tolerant, too.
Where to buy creeping thyme:
- Crocus: creeping thyme plants available in several colours.
- Amazon: a wide selection of creeping thyme plants for your garden.
3. Lesser periwinkle
There are ground cover plants to suit every soil type, meaning you'll find at least one match even in more challenging conditions.
'For drier soils in trickier, shadier locations such as under trees or on slopes and banks I would choose the lesser periwinkle, Vinca minor 'Variegata Alba',' says Kate Turner, gardening guru at Miracle-Gro. 'They have pretty, evergreen glossy leaves that have white edges and star-shaped white flowers.
'Unlike its cousin, the major periwinkle, this is easier to control and prettier, and it's one of the best ground cover plants to prevent weeds.'
Where to buy lesser periwinkle:
- Gardening Express: classic blue lesser periwinkle plants to add to your border.
- J Parker's: white lesser periwinkle ground cover plants are available.
4. Hardy geraniums
Hardy geraniums don't just look good in a garden border or raised flower bed – they're also one of the best ground cover plants to prevent weeds.
'For gorgeous spring to late summer flowering cover, go for cottage garden geraniums,' says Kate, for whom hardy geraniums are a number one choice.
'Not the big blowsy Mediterranean types used in containers and hanging baskets, but the lower growing, pinks, whites and blues of the perennial geranium such as Geranium Clarkeii 'Kashmir White' or Geranium Sanguineum. Pretty cup-shaped flowers on delicate foliage belies their toughness and these spread beautifully without becoming invasive.'
Annelise from Thompson & Morgan also recommends hardy geraniums as one of the best ground cover plants to prevent weeds: 'Geranium ‘Rozanne’ is the longest flowering ground cover geranium I know. It’s a vigorous and resilient plant, capable of bouncing back from the summer droughts we have been having while also coping well with winter wet.
'It has fairly lax, wiry stems, flopping nicely over edges or propping itself up against adjacent plants. Its flowering period is astounding and – provided it has sufficient moisture, sun and food – it will keep pumping out blooms from May to October.'
Where to buy hardy geraniums:
- J Parker's: a huge selection of hardy geraniums to choose from.
- Suttons: add a stunning hardy geranium collection to your garden.
5. Lady's mantle
Lady's mantle is a popular choice for garden borders, and it also makes the list of the best ground cover plants to prevent weeds – especially when coupled with catmint.
'Alchemilla mollis, or lady's mantle, is especially effective when partnered with varieties of catmint (Nepeta),' says Annelise.
'Both make excellent ground cover for border edges, are drought tolerant and enjoy free-draining, sunny sites. They have nicely contrasting foliage and flower in perfect unison with the lime-green frothy flowers of the Alchemilla, beautifully highlighting the blue spikes of the Nepeta.
'Once flowering is over, both can be cut right down to the ground and fed and watered, producing fresh foliage and hopefully a second flush of flowers.'
Where to buy lady's mantle and catmint:
- Thompson & Morgan: several varieties of lady's mantle to choose from.
- Sarah Raven: purple varieties of catmint to add to your garden border.
6. Heucheras
Heuchera are another popular ground cover plant that helps to prevent weeds. Not only do they make stunning winter flowers for hanging baskets and shade-loving plants for pots, but they also thrive in the ground.
‘Heucheras are excellent at any time of year, bringing unusual colour and stunning low mounds of foliage to borders and beds,’ says Stephanie Harrod, founder of Harrod Horticultural.

'With its evergreen foliage, it offers year-round greenery.'

FAQs
Do ground cover plants suppress weeds?
If you're wondering if ground cover plants will stop weeds growing in your garden, you'll be pleased to know it's one of several advantages they offer.
'Ground cover plants are traditionally used as weed cover and to help bind soil, especially on a slope,' says Kate Turner from Miracle-Gro. 'They are generally easy to maintain as well as being starters in their own right.
'Try not to choose anything too vigorous such as a low, fast-growing bamboo, which will take over your garden, or the classic Cotoneaster horizontalis, as this can look straggly very quickly and weeds always seem to find a way through!'
What is the best low maintenance ground cover?
'Creeping thyme, sedums, bugleweed, creeping Jenny, lesser periwinkle and Pachysandra are great examples of low-maintenance groundcovers,' says Jane from Allan's Gardeners.
'These fast-growing plants all provide unique benefits, like easily tolerating foot traffic, and can thrive with little care, making them excellent ground covers for low-maintenance gardens.'
