Edible ground covers are a crucial element in any permaculture or food forest garden. They serve as living mulch, protect and feed the soil, suppress weeds, and give you more food in less space. Whether you’re growing sweet potatoes for stir-fries or nasturtiums for a colorful salad, there are so many ways to make your ground layer both beautiful and functional.
Tired of weeding and bare soil? These low-growing edible plants cover the ground, feed your soil, and you!
By layering your garden with diversity in plant heights, root systems, and edible yields, you’ll create a more balanced, resilient system that supports you and the ecosystem around you. Let your mulch work to feed your soil and your family at the same time!
Welcome back to my garden! Today, we’re diving into edible ground covers that I use in my urban permaculture garden as living mulch. Creating layers in a food forest system helps you grow more diversity (and food) in a small space. Edible ground covers help suppress weeds to create a low-maintenance, sustainable garden that feeds us year-round and doesn’t demand daily upkeep.
We love to go camping, and that means I often leave my garden for days at a time. While I still love growing annuals like tomatoes and cucumbers, they require more hands-on care and come with a higher risk if I’m away. I’ll still grow them, but I want to shift the balance toward a more resilient garden using perennial plants and edible ground covers that do more of the heavy lifting while I’m off exploring.

Top 10 Edible Ground Covers for Living Mulch
So, what exactly are edible ground covers? These are low-growing plants that serve multiple functions: they protect the soil, retain moisture, reduce weeds, prevent erosion, and provide food for both humans and beneficial wildlife. In a food forest-style garden, ground covers are just one layer in a multi-tiered system that also includes tall trees, shrubs, flowers, and root crops.
Below are 10 of my favorite edible ground covers that are beautiful, functional, and delicious!
1. Sweet Potato
Sweet potato is hands-down my favorite edible ground cover. Its thick, lush vines protect the soil from the harsh sun and help retain moisture. The leaves are edible and can be used like spinach—sautéed with garlic, tossed in soups and curries, or even made into green wraps. And of course, the roots themselves are a delicious, substantial food source for both sweet and savory dishes. Sweet potatoes are also a haven for beneficial insects and frogs (yes, frogs!). I often find them nesting among the vines, even without a pond nearby. They’re super easy to propagate, making them perfect for sharing, selling, or expanding your patch.
2. Nasturtium
Nasturtiums are another edible ground cover that, once you plant them, you will have forever! Their bright flowers and peppery leaves are both edible and beautiful. I use the leaves in salads and as mini wraps, and the flowers as edible garnishes or pesto ingredients. They self-seed prolifically, meaning once you plant them, they often come back on their own every year. This means they can easily take over parts of your garden, so it’s important to keep them pruned if you want them to remain in one area.
Nasturtiums attract beneficial pollinators and act as a trap crop, luring pests like slugs and snails away from other plants. You can prune back areas to feed to your chickens as a natural pest management system. Even their seed pods are edible—you can pickle them to make homemade capers!
Naturtiums die off during the hot summer months, and so I pair these with sweet potato, which has an opposite growth pattern. Sweet potatoes thrive in summer and die back in the cooler months. These two work well to keep the soil covered all year round.
3. New Zealand Spinach (Tetragonia tetragonioides)
New Zealand Spinach is one of my go-to ground covers, especially in warmer weather when traditional leafy greens struggle. It spreads beautifully and creates dense, weed-suppressing coverage. The leaves are succulent and can be eaten cooked, much like regular spinach. It’s drought-tolerant, hardy, and perfect for low-maintenance edible landscaping. Due to its ability to self-seed easily, it can be a good idea to keep it contained.
4. Sweet Violet
Sweet violets (Viola odorata) make a lovely ground cover for shady areas, which become more common as fruit trees mature and cast more shade. They have heart-shaped edible leaves and delicate purple flowers that make beautiful decorations for cakes and salads. While I usually use the flowers more than the leaves, the entire plant helps retain soil moisture and suppress weeds, making it an excellent living mulch.
5. Strawberries
Strawberries are a classic edible ground cover that needs little introduction. They spread easily, especially alpine varieties, and can handle partial shade. While their leaves and flowers are edible, the fruit is the real star. Just note they do better in sunnier patches of your garden.
6. Prostrate Rosemary
This low-trailing form of rosemary hugs the ground and is well-suited to hot, dry, sandy, or rocky soils. It’s evergreen, hardy, and incredibly useful in the kitchen. I love having rosemary nearby to flavor dishes, and the edible flowers are great for attracting bees. It also has a host of medicinal benefits—anti-inflammatory, digestive support, and calming properties.
7. Thyme & Oregano
Thyme and oregano are aromatic culinary herbs that make wonderful low-growing ground covers in sunny areas. Their spreading habit helps protect the soil, and both are drought-tolerant and resilient. These herbs can be used fresh or dried for flavoring food, making teas, and for natural remedies. Their tiny flowers also attract pollinators to your garden.
8. Yarrow
Yarrow is a powerhouse plant often overlooked as an edible. While the leaves can be used in teas or medicinally (always research before consuming), their greatest strengths in the garden are as a soil protector with dense fern-like leaves and a pollinator magnet. It has deep roots that help break up compacted soil and draw nutrients up to the surface, improving fertility over time. It sends runners underground, so it’s a good idea to treat this plant like you would mint and keep it contained to one area.
9. Chamomile
Chamomile creates a fragrant, low-growing cover that’s sometimes used as a lawn substitute. It’s most well-known for its daisy-like flowers, which are harvested for calming teas that support sleep and digestion. It thrives in sunny areas and adds a beautiful, soft texture to garden beds.
10. Red Clover
Red clover is one of those quiet achievers in the garden, it’s beautiful, useful, and so easy to grow. I love using it as a living mulch in my food forest because it grows low to the ground, helps suppress weeds, and is constantly feeding the soil with nitrogen through its roots. The bees absolutely adore the flowers, and if you’re into herbal teas, the blossoms are edible and can be harvested and dried too! It’s the kind of plant that gives so much without asking for much in return—perfect for filling in those bare spots while still being productive and pretty.
Bonus: Edible Weeds (e.g. Purslane, Chickweed, Dandelion)
Many common weeds are edible and make great opportunistic ground covers. Purslane, for example, has succulent leaves rich in omega-3 fatty acids and grows rapidly to fill bare spots. Chickweed and dandelion also have edible and medicinal parts. While these can spread quickly, learning to identify and harvest them helps you turn a problem into a resource.
Living Mulch: Edible Ground Covers That Feed You and Your Garden
Start small by adding one or two edible ground covers to your garden beds or under fruit trees, and watch how quickly they transform the space. These hardworking plants not only fill gaps and reduce maintenance, but they also invite more life into your garden, as a wildlife habitat. Whether you’re building a full food forest or just looking to get more out of your patch, edible ground covers are one of the simplest ways to grow smarter, not harder.
