Edible ground covers are a powerful tool for gardeners seeking to maximize productivity, improve soil health, and create beautiful, resilient spaces. Unlike traditional ornamental ground covers, edible varieties offer the dual benefit of providing food while protecting and enriching the soil. This comprehensive guide explores the best edible ground covers for vegetable gardens, their benefits, and practical tips for successful integration.
Edible ground covers serve multiple functions in the vegetable garden:
-
: Dense foliage shades out weeds, reducing competition for nutrients and water.
-
: They act as living mulch, protecting soil from harsh sun, wind, and heavy rain, thus preventing erosion and moisture loss4.
-
: Many attract pollinators and beneficial insects, supporting a healthy garden ecosystem47.
-
: Some fix nitrogen or drop nutrient-rich leaves, improving soil fertility over time4.
-
: They provide harvestable leaves, fruits, or flowers for culinary use.
Below are some of the best edible ground covers, chosen for their resilience, culinary value, and ecological benefits.
1.
Sweet potato is a vigorous, sprawling vine that forms a lush, dense mat over the soil. Both the tubers and young leaves are edible—the leaves can be used in salads, stir-fries, or as a spinach substitute. Sweet potato is highly effective at moisture retention and erosion control, and its thick foliage provides habitat for beneficial insects47.
: Warm climates, full sun
: Edible tubers and leaves, excellent weed suppression, easy to propagate
2.
Nasturtiums are fast-growing, low-maintenance annuals with round, lily pad-like leaves and vibrant edible flowers. The leaves and flowers have a peppery flavor, perfect for salads and garnishes, while the seed pods can be pickled as capers. Nasturtiums attract pollinators and can serve as a trap crop for pests like aphids and slugs427.
: Full sun to part shade, borders, or interplanting
: Edible leaves, flowers, and seeds; attracts pollinators; pest management
3.
Alpine strawberries produce small, sweet fruits and create a dense, attractive ground cover. The plants are drought-tolerant, adaptable to sun or partial shade, and their leaves can be dried for tea. Alpine strawberries are perennial, providing fruit and soil protection year after year451.
: Edging beds, sunny or partially shaded areas
: Edible fruit and leaves, drought tolerance, perennial ground cover
4.
Thyme is a perennial herb with aromatic leaves and delicate flowers that attract pollinators. It forms a low, dense mat that can tolerate some foot traffic, making it ideal for pathways or between vegetable rows. Both common and lemon thyme varieties are excellent for culinary use593.
: Sunny, well-drained spots, pathways
: Culinary herb, pollinator-friendly, drought tolerant
5.
Oregano is a robust, spreading herb that thrives in sun or part shade. It deters pests, pairs well with a wide range of vegetables (especially brassicas), and offers flavorful leaves for cooking. Regular harvesting keeps it compact and productive254.
: Sunny beds, borders, companion planting
: Edible leaves, pest deterrence, perennial growth
6.
Sweet violets are low-growing, shade-tolerant perennials with edible flowers and leaves. The flowers, in shades of purple, pink, or white, are often used as garnishes or in baking. Sweet violets thrive in moist, shady spots and help retain soil moisture41.
: Shady areas, under trees
: Edible flowers and leaves, attractive blooms, shade tolerance
7.
Roman chamomile is a fragrant, mat-forming perennial with daisy-like flowers used for herbal tea. It’s suitable for sunny spots and can be used as a lawn alternative or between stepping stones. Chamomile’s flowers attract pollinators and beneficial insects45.
: Sunny, well-drained areas, pathways
: Edible flowers, herbal tea, pollinator support
8.
Prostrate rosemary varieties spread horizontally, forming aromatic, evergreen mats. The leaves are a kitchen staple, and the flowers attract bees. Rosemary is drought-tolerant and thrives in poor, sandy soils43.
: Dry, sunny slopes or rocky areas
: Edible leaves, drought resistance, perennial
9.
Mint spreads rapidly to form dense ground cover, especially in moist, partially shaded areas. Corsican mint is particularly low-growing and aromatic. All mints are edible, but they can become invasive, so consider containing them in beds or pots213.
: Damp, semi-shaded spots, under trees
: Edible leaves, aromatic, attracts pollinators
10.
Cranberries form low, sprawling mats and produce tart, nutritious berries. They require acidic, moist soils and are best suited to low-lying or boggy areas. Once established, cranberries are long-lived and productive4.
: Acidic, moist soils, cool climates
: Edible fruit, perennial, soil stabilization
11.
New Zealand spinach is a heat-tolerant, spreading annual or short-lived perennial that produces succulent, edible leaves. It forms a thick ground cover and is ideal for coastal or sandy soils48.
: Warm climates, sandy soils
: Edible leaves, heat tolerance, soil protection
12.
Purslane is a succulent, low-growing annual with crunchy, lemony-flavored leaves. It thrives in poor soils and hot, dry conditions. Purslane is highly nutritious, rich in omega-3 fatty acids, and can be used raw or cooked18.
: Hot, dry spots, between vegetable rows
: Edible leaves and stems, drought tolerance, self-seeding
13.
Surprisingly, kale can function as an edible ground cover, especially when allowed to self-seed. Young kale plants create a leafy mat that shades soil and provides a steady harvest of greens. It performs well under partial shade, such as beneath fruit trees6.
: Partial shade, under trees
: Edible leaves, nutrient-dense, self-seeding
14.
Clovers are often used in vegetable gardens as living mulch. While not a traditional edible, clover leaves and flowers are technically edible and can be used in teas or salads. More importantly, clover fixes atmospheric nitrogen, enriching the soil for neighboring vegetables3.
: Pathways, between rows, soil improvement
: Nitrogen fixation, edible flowers and leaves, weed suppression
:
Select ground covers based on your climate, soil conditions, and the needs of your main crops. For example, sweet potato and New Zealand spinach excel in heat, while violets and mint thrive in shade.
:
Establish perennial ground covers in early spring or fall. Annuals like nasturtium and purslane can be direct-sown after frost.
:
Some edible ground covers, such as mint and sweet potato, can be vigorous. Regular harvesting and pruning keep them in check and productive.
:
Use a mix of ground covers for year-round protection and harvest. For example, alternate sweet potato (summer) with nasturtium (cooler months) for continuous coverage7.
:
Many edible ground covers double as companion plants, deterring pests or attracting pollinators. Oregano and thyme, for example, are excellent companions for a range of vegetables25.
Edible ground covers do more than provide food—they create a living mulch that:
-
: By shading the soil, ground covers significantly cut down on evaporation.
-
: Their roots help prevent compaction and increase organic matter.
-
: Many provide habitat and nectar for pollinators and beneficial insects, boosting garden resilience47.
-
: Their dense mats hold soil in place during heavy rains4.
-
: Some, like mint and sweet potato, can overrun small spaces. Use barriers or containers if needed.
-
: Dense ground covers may compete with young vegetable seedlings for light and nutrients. Plant after main crops are established or thin as needed.
-
: Not all ground covers thrive in every climate. Match species to your local conditions for best results.
Conclusion
Edible ground covers are a smart, sustainable choice for any vegetable garden. By selecting the right mix of species—such as sweet potato, nasturtium, alpine strawberry, thyme, oregano, and others—you can enjoy a garden that’s productive, beautiful, and resilient. These living mulches not only provide delicious harvests but also protect and enrich your soil, support pollinators, and reduce maintenance. With thoughtful planning and management, edible ground covers can transform your vegetable garden into a thriving, multifunctional ecosystem.
