Peppers, whether sweet bell types or fiery hot varieties, are one of the most rewarding crops a home gardener can grow, often producing steadily from midsummer until the first frost. A single healthy pepper plant can yield anywhere from 5 to 10 pounds of fruit over a season depending on the variety and growing conditions, which makes getting the surrounding plant community right well worth the effort. This is where companion plants for peppers become useful, since the right neighbors can help repel pests, draw in pollinators, improve soil structure, and make more efficient use of limited garden space, all without asking much extra from the gardener.
Peppers are somewhat particular in their needs, generally requiring soil temperatures above 65°F to grow well and at least 6 to 8 hours of direct sun each day to produce a strong fruit set. Because pepper plants are relatively compact and slow to establish compared to fast-growing vegetables like squash or beans, they benefit from companions that fill in surrounding space without shading them out or competing too aggressively for water and nutrients. Aromatic herbs are a particularly common choice, since compounds in their foliage are widely believed to disrupt the ability of pests such as aphids and flea beetles to locate host plants by scent, while flowering companions draw in bees and other pollinators that can improve fruit set by a noticeable margin.
Good companion planting around peppers also plays a role in disease and pest management more broadly. Certain nematode populations in soil, for instance, can be reduced significantly, in some studies by as much as 90 percent in the root zone, when marigolds are grown in the same bed over a full season. Other companions, particularly nitrogen-fixing legumes, can meaningfully boost the nitrogen available in the surrounding soil, supporting the fairly moderate but steady feeding needs of pepper plants throughout their long growing season. The fifty companions described below span herbs, flowers, vegetables, and alliums, each offering its own practical or ornamental benefit to a pepper bed.

Plants That Grow Well With Peppers
Basil
Basil is one of the most frequently recommended companions for peppers, its strong scent believed to help mask pepper foliage from aphids and certain moths. Its bushy, compact growth habit fits neatly around the base of pepper plants without competing much for light. Many gardeners also grow basil near peppers simply because the two are frequently used together in the kitchen.
Marigolds
Marigolds are planted near peppers largely for their root exudates, which have been shown in various studies to suppress harmful root-knot nematodes in the surrounding soil. Their bright orange and yellow flowers also attract pollinators and can serve as a decoy for certain pests. Marigolds are easy to grow from seed and typically bloom continuously from early summer through the first frost.
Nasturtium
Nasturtiums are a classic trap crop, drawing aphids toward their own leaves and away from tender pepper foliage. Their trailing habit and bright, edible flowers add color at the base of pepper plants. Because they thrive in poor, low-fertility soil, nasturtiums require very little extra care to perform well as a companion.
Chives
Chives are commonly grown near peppers for their mild pest-repellent scent, which is thought to deter aphids and certain beetles. Their narrow, grass-like foliage takes up very little space, making them easy to tuck along the front edge of a pepper bed. As a perennial herb, chives can remain in place for several years with minimal upkeep.
Garlic
Garlic’s strong sulfur compounds are widely believed to help repel aphids and spider mites when grown near peppers. It is typically planted in fall for a summer harvest, meaning it occupies the bed at a different point in the season than actively fruiting peppers. Its narrow, upright growth allows it to be planted between pepper plants without crowding them.
Onions
Onions are frequently interplanted with peppers, their pungent scent thought to help mask peppers from pests that locate host plants by smell. Onions typically mature in around 100 to 120 days, allowing many varieties to be harvested before pepper plants reach peak production. Their upright form means they take up relatively little lateral space in a mixed bed.
Oregano
Oregano’s low, spreading growth habit makes it a useful living mulch beneath pepper plants, helping retain soil moisture in the root zone. Its aromatic foliage is thought to help confuse pests that hunt by scent. As a hardy perennial in many climates, oregano can remain part of the same bed year after year.
Parsley
Parsley attracts a range of beneficial insects, including hoverflies and parasitic wasps, particularly once it’s allowed to flower in its second year. Its dense, ferny foliage helps shade the soil around pepper roots, reducing moisture loss. As a biennial, parsley may need occasional replanting to remain a consistent companion.
Thyme
Creeping thyme forms a low, fragrant mat that suppresses weeds and helps retain soil moisture beneath pepper plants. Its small flowers are highly attractive to pollinating bees, which supports better fruit set on nearby peppers. Because it stays close to the ground, thyme rarely competes with peppers for sunlight.
Dill
Dill attracts beneficial predatory insects such as ladybugs and lacewings, both of which help keep aphid populations under control near pepper plants. It’s best kept a short distance from peppers, since mature, flowering dill can occasionally inhibit the growth of nearby nightshades. Its feathery foliage adds a soft textural element to a pepper bed.
Cilantro
Cilantro draws in a variety of small beneficial insects when allowed to flower, helping manage common pepper pests. It has a fairly short growing season, often bolting within 45 to 60 days in warm weather, so it tends to work best as an early or late-season companion. Its airy white flower clusters add a light textural contrast near peppers.
Sage
Sage’s woody, aromatic foliage is thought to help deter certain moths and beetles when grown near peppers. It prefers similarly well-draining soil, making it compatible with pepper growing conditions. Sage also draws in pollinators when it blooms, supporting the wider garden ecosystem.

Mint
Mint’s strong scent is believed to help repel aphids and certain moths, but it should be grown in a container even within a pepper bed, since its roots spread aggressively and can overtake nearby plants within a single season. When allowed to flower, mint attracts a wide range of pollinators. Careful containment is essential to using it successfully near peppers.
Lemon Balm
Lemon balm’s citrus scent is thought to help mask peppers from pests that rely on smell to locate host plants. It spreads readily, so many gardeners keep it contained or planted at a slight distance from peppers. Its small white flowers, when allowed to bloom, attract pollinators to the surrounding bed.
Rosemary
Rosemary’s evergreen, needle-like foliage adds structure to a pepper bed, particularly useful since peppers themselves are relatively compact and slow to fill out early in the season. Its pale blue flowers in late winter or early spring offer color before peppers are even in the ground. Both plants share a preference for full sun and well-draining soil.
Petunia
Petunias are often interplanted with peppers for their believed ability to deter certain beetles and aphids, along with a long season of colorful blooms. Their trailing, mounding habit fills bare soil around pepper plants, helping suppress weeds. They also attract pollinators, supporting fruit set on nearby pepper flowers.
Zinnia
Zinnias bring strong color and are highly attractive to pollinators and beneficial insects such as ladybugs, which prey on aphids. Their upright, sturdy stems add structural variety without shading out peppers. Zinnias are easy to start from seed and bloom reliably through the hottest part of summer.

Calendula
Calendula is planted near peppers both for its cheerful blooms and its ability to attract predatory insects that help manage aphid populations. It can also act as something of a trap crop, drawing aphids toward its own foliage. Calendula tolerates cooler temperatures well, extending color into the shoulder seasons of the pepper growing period.
Cosmos
Cosmos adds height and airy, feathery foliage to a pepper bed, along with daisy-like flowers that draw in pollinators and beneficial insects. Their tall, slender stems rarely compete significantly with peppers for light. Once established, cosmos is quite drought-tolerant, needing little extra water.
Alyssum
Sweet alyssum forms a low, dense carpet of tiny, fragrant flowers that attract pollinators and beneficial insects such as hoverflies. Its shallow root system draws moisture and nutrients from a different soil layer than peppers, minimizing competition. Alyssum’s spreading habit also helps shade the soil surface around pepper roots.
Geraniums
Geraniums, especially scented varieties, are sometimes grown near peppers for their believed ability to deter Japanese beetles and certain other pests. Their compact, mounding form fits easily along the edges of a pepper bed. Their long bloom season provides steady color through much of the growing period.
Yarrow
Yarrow’s flat clusters of small flowers attract ladybugs, lacewings, and other beneficial insects that help control aphid populations near peppers. Its fine, ferny foliage is quite drought-tolerant, requiring little supplemental water once established. Yarrow also contributes organic matter to the soil as its leaves break down over time.
Sunflower
Tall sunflower varieties can provide a natural windbreak for pepper plants, which are often vulnerable to wind damage due to their relatively brittle stems. Sunflowers attract pollinators and can act as a trap crop for certain stink bugs, drawing them away from developing pepper fruit. Adequate spacing helps prevent sunflowers’ extensive root systems from competing too heavily with peppers.
Bee Balm
Bee balm’s tubular flowers are a strong draw for bees and hummingbirds, which can meaningfully improve pollination rates for nearby pepper flowers. Its aromatic foliage may also help deter some pests. Bee balm prefers slightly more consistent moisture than peppers, so it works best at the moister edges of a bed.
Sweet William
Sweet William offers fragrant, colorful blooms that attract pollinators to a pepper bed. As a biennial, it typically flowers in its second year, providing a different bloom cycle than many annual companions. Its compact size allows it to be planted along the front of a pepper row without shading the plants.
Daisies
Shasta daisies and similar daisy-type flowers attract a wide range of pollinators and beneficial insects to a pepper bed, supporting improved fruit set overall. Their simple white and yellow blooms contrast nicely with the deep green of pepper foliage. Most daisies tolerate the same well-draining soil conditions peppers prefer.
Verbena
Verbena’s clusters of small, colorful flowers form a low, spreading groundcover beneath taller pepper plants, helping fill bare soil and suppress weeds. It blooms nearly continuously through the warm season and is highly attractive to pollinators. Its trailing habit is useful along bed edges or between pepper rows.
Carrots
Carrots grow well beneath pepper plants since their root systems occupy a different soil depth, allowing efficient use of the same bed. The loose, well-draining soil carrots prefer is broadly compatible with pepper growing conditions. Carrots also benefit from the light afternoon shade cast by taller pepper foliage in the height of summer.
Beets
Beets share similar soil preferences with peppers, favoring loose, fertile, well-draining ground. Their relatively shallow root systems allow them to be planted between pepper rows without major competition for deeper soil resources. Beet greens also help cover bare soil, reducing moisture loss and weed pressure.
Radish
Radishes mature quickly, often within 3 to 4 weeks, making them a useful early companion planted around young pepper transplants before the peppers fill out. Some gardeners use radishes as a trap crop for flea beetles, which may target radish foliage over young pepper leaves. Their compact size means they don’t interfere with developing pepper roots.
Green Beans
Bush beans fix nitrogen in the soil through bacteria in their root nodules, which can meaningfully benefit the moderate but steady feeding needs of nearby pepper plants. Their compact, bushy growth fits well into the lower layer of a pepper bed. Beans are typically spaced to avoid excessive shading of pepper plants, which can be sensitive to reduced light in their early growth.
Peas
Like beans, peas are nitrogen-fixing legumes that can improve soil fertility ahead of a pepper crop. Because peas are a cool-season plant, they are usually grown and harvested earlier in spring, finishing before peppers require the bulk of the bed’s space. Their vining habit can be trained onto simple supports at the edge of a pepper patch.

Lettuce
Lettuce makes an efficient early-season companion for peppers, since it can be harvested and cleared out before pepper plants grow large enough to need the full bed. Its shallow root system draws moisture and nutrients from a different soil layer than peppers, minimizing competition. Lettuce also helps cover bare soil early in the season, reducing weed pressure around young pepper transplants.
Spinach
Spinach is a cool-season crop that can share a bed with peppers during the early part of the year, before peppers mature and require more space and light. Its low, spreading rosettes help retain soil moisture and suppress early weeds. Spinach is typically finished and harvested well before peppers reach peak production.
Cucumbers
Cucumbers share similar warm-season growing requirements with peppers, including full sun and consistently moist, fertile soil. Vertical trellising for cucumbers helps maximize space in a bed that also includes pepper plants. Both crops benefit from good airflow, since both can be somewhat prone to fungal disease in humid conditions.
Eggplant
Eggplant, a close relative of peppers in the nightshade family, shares similar cultural requirements and can be grown in the same bed with little adjustment in care. Its broad leaves add visual variety among more compact pepper plants. Crop rotation is recommended for both, since nightshade relatives can share certain soilborne diseases.
Tomatoes
Tomatoes and peppers are commonly grown side by side, since both are warm-season nightshades with similar sun, soil, and watering needs. Growing them together simplifies fertilization and irrigation schedules across the bed. As with other nightshade pairings, rotating the location of both crops each year helps reduce disease buildup in the soil.
Squash
Squash, particularly bush varieties, can be grown near peppers to make efficient use of ground space, its broad leaves helping shade out weeds at the base of the bed. Both crops require full sun and consistent moisture, aligning their basic care needs. Adequate spacing is important, since squash vines can spread significantly if left unchecked.
Okra
Okra shares peppers’ preference for hot weather and well-draining soil, often thriving in the same conditions that cause other vegetables to struggle. Its tall, upright form can provide light dappled shade for peppers during the most intense heat of midsummer. Both crops tend to produce steadily over a long harvest window.
Asparagus
Asparagus and peppers are sometimes paired at the edges of a vegetable garden, with compounds from asparagus roots believed to help suppress certain nematodes that can also affect peppers. Because asparagus is a long-lived perennial, it typically occupies a fixed spot rather than being intermixed directly with pepper plants. This pairing works especially well in permanent raised bed systems.
Leeks
Leeks, like onions and garlic, are believed to help mask peppers from pests that locate host plants by scent. Their tall, narrow form allows them to be planted in tight rows between pepper plants without much competition for light. Leeks have a long growing season, often remaining in the ground well into the pepper harvest period.

Celery
Celery’s dense, upright growth pairs well with peppers in terms of spacing, and it requires consistently moist soil that aligns reasonably well with a pepper’s own watering needs. Its presence is thought to help deter certain pests that occasionally stray into a pepper bed. Celery’s ribbed stalks also add textural variety to a mixed vegetable planting.
Amaranth
Amaranth is sometimes used as a trap crop near peppers, drawing certain pests toward its foliage instead of the vegetable crop. Its tall, colorful seed heads add ornamental interest to a pepper bed. Amaranth is drought-tolerant and undemanding, requiring little special care.
Lovage
Lovage is a tall, celery-like herb sometimes planted near peppers for its believed ability to attract beneficial insects when in flower. Its substantial mature size, often reaching 3 to 4 feet, means it’s best placed toward the back or edge of a pepper bed. As a hardy perennial, lovage can remain in place for years once established.
Chamomile
Chamomile’s small white and yellow flowers attract hoverflies and other beneficial insects that help control aphid populations around peppers. It is also thought to contribute beneficial compounds to the soil as its foliage decomposes. Chamomile’s low, mounding habit keeps it from competing significantly with pepper plants for light.
Tansy
Tansy’s button-like yellow flowers are thought to help repel certain beetles and ants when grown near peppers. It can spread aggressively, so it is often planted with a root barrier or kept at the margins of a bed. Tansy is quite hardy and tolerates a range of soil conditions.
Horehound
Horehound is sometimes planted near peppers for its believed ability to attract beneficial insects and support the general health of nearby plants. Its fuzzy, gray-green foliage provides a textural contrast to pepper leaves. It is drought-tolerant and undemanding, requiring little supplemental care.
Marjoram
Marjoram, closely related to oregano, offers a similarly low, spreading growth habit that works well as groundcover beneath pepper plants. Its aromatic foliage is thought to help confuse pests that rely on scent to locate host plants. In mild climates, marjoram can persist as a perennial in the same bed across multiple seasons.
Borage
Borage attracts pollinators and predatory insects such as parasitic wasps that help control common pepper pests. Its star-shaped blue flowers are edible and add ornamental value to a vegetable bed. Borage often self-seeds readily, meaning it may return on its own in following seasons.

Horseradish
Horseradish is sometimes planted at the corners of a pepper bed for its reputed ability to help protect nearby plants from certain fungal issues and pests, thanks to compounds in its roots and leaves. Because it spreads via deep, persistent roots, it is generally kept in a contained area rather than planted directly among peppers. Once established, horseradish requires very little ongoing maintenance and can remain productive for many years.
