These heirloom nasturtium seeds produce a cheerful mix of red, orange, and yellow edible blooms on compact, low-maintenance plants. Ideal for gardeners seeking a dual-purpose flower that deters pests and attracts pollinators, though some seeds benefit from pre-soaking to boost germination.
Pros & Cons

Pros

  • Edible flowers and leaves with a unique peppery flavor
  • Attracts pollinators and deters garden pests naturally
  • Compact growth habit suits containers and small spaces
  • High germination rate when seeds are nicked and soaked
  • Heirloom, non-GMO, open-pollinated quality from a trusted brand

Cons

  • Some seeds may need pre-treatment (nicking or soaking) for best germination
  • A few customers reported poor germination, possibly due to late planting or over-drying
  • Not a trailing variety - compact form may not suit those wanting a cascading look
Detailed Review

The Survival Garden Seeds Nasturtium Tip Top Mix offers an easy way to add color, edible blooms, and natural pest control to your outdoor garden. This heirloom variety produces a compact mound of cheerful orange, yellow, and red flowers on bushy plants that reach about 12 inches tall. It's an excellent choice for container gardeners, border planters, or anyone wanting a low-maintenance flower that does double duty as a companion plant for vegetables like cucumbers, squash, and tomatoes.

In practice, many users report strong germination rates after nicking the hard seed coat and soaking the seeds overnight. The plants grow quickly and stay tidy, blooming continuously from summer through frost. The petals and leaves have a pleasantly peppery taste, making them a fun addition to salads or as a garnish. The flowers also reliably attract bees, butterflies, and hummingbirds, while the foliage helps repel aphids and other pests in nearby vegetable beds.

Build quality is solid for seeds - they come in two resealable packs with clear instructions. The brand, Survival Garden Seeds, is a family-owned American company that tests for quality and uses only non-GMO, open-pollinated seeds. The packaging lists necessary details like USDA hardiness zones 3-10 and full sun requirements.

A few drawbacks exist. Some gardeners found that late-season planting or hot, dry conditions led to poor germination even from the same packet. A minority of customers reported near-zero germination, though others succeeded with the recommended pre-soaking method. Also, this is a dwarf (nanum) variety, not a trailing nasturtium, so it won't spill over edges like some expect.

Overall, the Tip Top Mix is a reliable, versatile seed pack for anyone wanting an edible, pollinator-friendly, and pest-deterring flower. With proper seed prep and timely planting, it delivers vibrant blooms and garden benefits throughout the warm months. It's a solid value for home gardeners who value both beauty and functionality.

  • Compact size suits small gardens and containers

Cons

  • Not a super-hot pepper; Scoville rating is very low (mild to no heat)
  • Plants may need staking if they become heavy with fruit
  • USDA zone 10 recommended; colder climates require starting indoors or using season extenders
Detailed Review

The Bonnie Plants Shishito Pepper 4-pack is a fantastic shortcut for anyone who wants to grow these trendy Japanese peppers without the hassle of starting from seed. Each pack contains four live plants that are ready to go into the ground or a container as soon as the weather warms up. Shishitos are famous for their mild, sweet flavor and thin, tender walls that blister beautifully under high heat.

These plants are compact, reaching about three feet tall, so they fit nicely on a sunny patio or balcony. They produce a steady supply of finger-long peppers that are typically harvested green but can be left to ripen red for a slightly sweeter taste. The real magic happens in the kitchen: toss them in oil, sear them in a hot pan or on the grill until they're charred and blistered, then sprinkle with salt. It's a simple, addictive appetizer that's become a staple in restaurants.

From a growing perspective, these plants are low-maintenance. They need full sun and consistent watering about twice a week. The 60- to 80-day maturity means you'll be picking peppers by mid to late summer. One thing to keep in mind: shishitos are not hot peppers. They rate near zero on the Scoville scale, so if you're looking for heat, this isn't the variety for you. But for mild, sweet peppers with a unique texture, they're hard to beat.

Overall, the Bonnie Plants Shishito Pepper 4-pack is a reliable, beginner-friendly way to grow a chef-favorite pepper at home. The plants are vigorous, the harvest is generous, and the culinary possibilities are endless. Just be ready to share with friends because once you start cooking them, everyone will want some.

This 4-pack of Bonnie Plants green bell pepper starters gives you a head start on the season, producing large, sweet peppers perfect for slicing, stuffing, or freezing. Ideal for gardeners who want a reliable, high-yielding crop without starting from seed.
Pros & Cons

Pros

  • Live plants provide a significant head start compared to seeds.
  • High productivity: yields lots of large, sweet bell peppers over the growing season.
  • Non-GMO and from a trusted brand (Bonnie Plants).
  • Versatile use in the kitchen: slicing, stuffing, freezing, or fresh eating.
  • Suitable for container gardening with proper staking.

Cons

  • Plants need staking as they mature and become loaded with fruit, adding a bit of extra care.
  • Not frost tolerant; must be planted after the last frost and protected from cold weather.
  • Limited to green bell peppers at harvest; if you want red or other colors, you'll need to let them ripen longer on the plant.
Detailed Review

Bonnie Plants has been a go-to brand for home gardeners for years, and their Green Bell Pepper live plant 4-pack lives up to that reputation. This set gives you four young, healthy pepper plants that are already several weeks old, so you can skip the delicate seed-starting phase and jump straight into a productive garden. It's an excellent choice for anyone who wants a reliable, high-yielding crop of sweet green bell peppers without the wait or guesswork of seeds.

What makes these plants stand out is their proven productivity. According to the product description, they are Bonnie's most popular bell pepper for a reason. The plants produce a heavy yield of large, sweet peppers that work beautifully for slicing into salads, stuffing with your favorite fillings, freezing for later use, or just eating fresh off the vine. The peppers are crisp and mild, with zero heat, making them a versatile kitchen staple. The plants thrive in full sun and need consistent moisture, but they're not overly fussy. One thing to note: as the fruit load increases, staking becomes necessary to keep the plants upright. That's a small price to pay for such a generous harvest.

In terms of design and build quality, these are live, bare-root starter plants shipped in a protective container. The plants arrive well-rooted and ready to transplant. They are non-GMO, and Bonnie Plants emphasizes strong root development and vigorous growth. The 4-pack is perfect for small to medium gardens or for filling a few large containers on a patio. With a maturity of 75 days or more from planting, you can expect to start picking green peppers by midsummer if you plant in spring.

There are a couple of honest drawbacks. First, these plants are not frost-tolerant, so you need to wait until after the last spring frost to plant them, and a sudden cold snap can damage them. Second, the peppers are picked when green, but they will turn red, orange, or yellow if left on the plant longer. If you prefer colored bell peppers, you'll need to be patient. Also, staking is a must for heavy crops, which is an extra step some gardeners might not want.

Overall, the Bonnie Plants Green Bell Pepper 4-pack offers a fantastic head start for home gardeners who want a bountiful, easy-to-grow pepper crop. They are productive, tasty, and versatile. If you want to simplify your gardening and get to harvest faster, this is a solid choice. Just be ready to stake them and protect them from frost, and you'll be rewarded with plenty of sweet peppers.

Cons

  • Slow initial growth; needs a long, warm growing season to reach full potential
  • A few customers received plants that died within a week, possibly due to transplant shock or shipping stress
Detailed Review

The Bonnie Plants Red Ghost Pepper 4-pack is a fantastic shortcut for anyone who wants to grow one of the world's hottest peppers without the hassle of starting from seed. Each pack contains four live heirloom Bhut Jolokia plants, also known as ghost peppers, which can reach over 1 million Scoville heat units. This product is perfect for chili enthusiasts who want to add serious heat to their garden and kitchen.

The standout feature is convenience. Instead of waiting weeks for seeds to germinate, you get established plants that can go straight into the ground or a container. Many buyers praised the packaging: a sturdy box with individual pots and separators kept the plants healthy during transit. Once planted in full sun and watered regularly, these peppers thrive and produce abundant fruit. The plants can grow up to 4 feet tall, so staking or caging is a good idea. Reviews consistently mention strong growth and a heavy yield of wrinkled red peppers.

That said, there are some drawbacks. A few customers reported that plants arrived dry or wilted, though most perked up after watering. A small number of plants died within a week, which may be due to shipping stress or improper care after arrival. Also, ghost peppers are slow starters and need a long, warm growing season (100-120 days to maturity). If you live in a cooler climate, you might need a greenhouse or indoor setup.

Overall, the Bonnie Plants Red Ghost Pepper 4-pack is a reliable way to grow authentic ghost peppers at home. The convenience of live plants, combined with the brand's reputation for quality, makes it a solid choice for anyone ready to handle the heat. Just be prepared to give them the sun and time they need.

These heirloom Poblano Ancho Grande pepper seeds from Isla's Garden Seeds offer quick germination and a mild, smoky flavor that works great for roasting, stuffing, or drying. A solid pick for home gardeners who want a versatile, high-yield pepper for authentic Mexican dishes.
Pros & Cons

Pros

  • Fast, reliable germination - many customers report sprouts within 10 days
  • Versatile in the kitchen: fresh, roasted, dried, or ground into chili powder
  • Adaptable to a wide range of climates (zones 3-12)
  • High yield potential with proper care
  • Affordable quantity of 50+ seeds per pack

Cons

  • Requires warm soil (70-80°F) for best germination, so northern growers may need a heat mat
  • Moderate watering needs - not ideal for forgetful gardeners
  • Mature peppers take 75-85 days, so a bit of patience is needed
Detailed Review

If you're looking to add a versatile, mild pepper to your garden, the Poblano Ancho Grande from Isla's Garden Seeds is a solid choice. These heirloom, non-GMO seeds produce the classic poblano pepper you know from Mexican cuisine, but with a twist: let them ripen to red and dry them out, and you've got authentic ancho chiles. That dual-purpose nature alone makes them a great value for home cooks and gardeners alike.

Standout features include the mild heat level (barely a kick) and that signature smoky-sweet flavor. The plants are described as high-yield, and customer reviews back that up - many report quick germination and healthy seedlings. One reviewer saw sprouts in just 10 days using a hydroponic setup, while another noted 90% germination from direct sowing. That kind of reliability is rare with pepper seeds.

Growing these peppers is straightforward: start seeds indoors 6-8 weeks before last frost, keep the soil warm (70-80°F), and transplant after danger of frost. The plants need full sun and moderate watering. They'll grow 2-3 feet tall and spread about 18-24 inches apart. The 70-day maturity for green peppers is reasonable, though letting them fully ripen to red takes a bit longer. The thick-walled flesh makes them ideal for stuffing, roasting, or grilling.

One minor drawback: if you're in a cooler zone, you'll need to start seeds indoors or use a heat mat, as they require consistent warmth. Also, while the seeds are affordable (50+ per pack), you'll need patience to wait for the full drying process if you want Ancho chiles. But for most home gardeners, these are easy wins.

Overall, the Isla's Garden Seeds Poblano Ancho Grande is a dependable, flavor-packed pepper variety that delivers on its promises. The high germination rate, versatile kitchen uses, and adaptability across zones 3-12 make it a smart addition to any vegetable garden. Whether you're a seasoned grower or a beginner, these seeds are worth your time.

This plant produces striking peppers with a deep chocolate brown base streaked with golden yellow and orange, making it a standout in any vegetable garden. It is best suited for home gardeners who enjoy growing unique, gourmet produce and want something visually impressive for both eating and display.

The standout feature is the pepper's appearance. Each fruit is like a little work of art, but the flavor is just as appealing. These are sweet bell-type peppers with thick, crunchy walls, perfect for fresh eating, grilling, or stuffing. The plants are shipped as healthy, well-rooted seedlings, ready to be transplanted into your garden or a large patio container. They need full sun and regular watering, and they produce abundant fruit throughout the growing season.

As a starter plant from CZGrain, the quality of the seedling is generally good, with strong roots and healthy leaves. However, at this price point, you are paying for the novelty of the rare variety more than for volume. The plant is non-GMO, which will appeal to organic and natural gardening enthusiasts.

Potential drawbacks include the lack of customer reviews to validate performance, and the plant may require some patience to establish and start fruiting. It is not the cheapest pepper starter, but for collectors or adventurous cooks, the visual and culinary payoff can be worth it.

This 5-pack of live pepper starter plugs from Bellawood Horticulture includes Bell, Jalapeno, Sweet Banana, Habanero, and Cayenne varieties, giving gardeners a head start over seeds. The plants arrive as small plugs in protective clamshells, but review feedback shows mixed condition upon arrival with some arriving small or dead.
Pros & Cons

Pros

  • Live starter plugs give a faster start than growing from seed
  • Protective clamshell packaging reduces damage during shipping
  • Variety pack offers multiple pepper types for different culinary uses
  • Positive reviews highlight healthy plants and responsive customer service

Cons

  • Size upon arrival can be smaller than expected (2-5 inch plugs)
  • Some plants may arrive dead or in poor condition based on customer reviews
  • Mixed quality control; not all plants are equally vigorous
Detailed Review

The Bellawood Horticulture Live Pepper Plants 5 Pack gives gardeners a convenient way to start a pepper garden without the wait of seeds. This set includes Bell, Jalapeno, Sweet Banana, Habanero, and Cayenne varieties, all shipped as live starter plugs typically 2 to 5 inches tall. It's aimed at home gardeners who want a simple, all-in-one bundle of popular peppers for cooking, grilling, or making salsa.

The standout feature is the head start these live plants provide. Instead of nurturing seeds for weeks, you receive established plugs ready to transplant after the last frost. The protective plastic clamshell packaging is a thoughtful addition that helps keep the plants safe in transit. However, real-world performance is mixed. Some customers report healthy, perky plants that thrive, while others received dry or dead plugs that were smaller than expected. Customer service seems responsive when issues arise, which is a plus.

Design and build quality are straightforward: these are starter plugs in a secure clamshell, not potted plants. They need full sun and work in USDA zones 3 through 11 as annuals. The variety is the main selling point, but the small plug size means they need careful handling and ideal growing conditions to succeed.

Drawbacks include the risk of receiving plants in poor condition and the fact that plug size can be underwhelming for the price. Two negative reviews cite dead or near-dead plants, while positive reviews highlight healthy growth and good customer service. This inconsistency suggests quality control could be tighter.

Verdict: If you get a healthy batch, this set offers great value with five pepper varieties and a head start on the season. But be prepared for potential disappointment if some plants arrive stressed. Order early and be ready to nurture them. For the price, it's a gamble worth taking if you appreciate variety.

The Bonnie Plants Hot Cayenne Pepper 4-Pack delivers vigorous, high-yielding plants that produce fiery red peppers with a Scoville rating of 30,000 to 50,000, perfect for gardeners who want fresh heat without starting from seed.
Pros & Cons

Pros

  • High yield of flavorful, hot peppers from each plant
  • No need to start from seed; plants arrive ready to transplant
  • Excellent for drying, making pepper sauce, or stringing into ristras
  • Well-protected packaging ensures healthy arrival, based on positive reviews
  • Plants produce continuously through the season for a steady supply

Cons

  • Some plants may arrive slightly wilted or stressed from shipping (most recover with water and sun)
  • A few customers reported plants dying within a week, despite careful handling
  • Requires full sun and consistent moisture, limiting options for shady or low-water gardens
Detailed Review

The Bonnie Plants Hot Cayenne Pepper 4-Pack is a solid choice for home gardeners who crave authentic heat without the hassle of starting seeds. Each pack contains four young plants in 19.3-ounce pots, ready to be transplanted into a sunny garden or large container. With a Scoville rating of 30,000 to 50,000, these peppers bring genuine fire to salsas, sauces, and infusions, while still allowing the pepper's fruity flavor to shine.

What sets this product apart is the convenience: you skip the weeks of seed starting and get a head start on the growing season. Customers consistently praise the packaging, which includes a rigid box with separators to keep plants safe during transit. Most plants arrive healthy and vigorous, though some reviewers noted that a few arrived wilted or damaged. That said, with prompt watering and sunlight, the majority bounce back quickly and go on to produce heavy yields.

The plants themselves are robust, growing up to three feet tall in full sun and sandy soil. Harvest typically begins around 85 days after planting, and the peppers keep coming throughout the season. The thin walls make them ideal for drying, pickling, or stringing into ristras. Just remember to wear gloves when handling the peppers, as the capsaicin can irritate skin.

On the downside, a small number of buyers reported plants that didn't survive, and the product demands consistent moisture and full sun, so it's not for every garden. The price point is reasonable given that you're getting established plants rather than seeds, but it's worth noting that results can vary based on your local conditions and care.

Overall, the Bonnie Plants Hot Cayenne Pepper 4-Pack is a reliable option for anyone looking to add serious heat to their garden without the extra effort. If you have a sunny spot and a taste for spicy food, these plants are a practical, rewarding investment.

Frequently Asked Questions About Companion Planting for Peppers

What are the best companion plants for peppers?

Some of the most effective companion plants for peppers include nasturtium, basil, marigolds, and parsley. Nasturtium, like the Tip Top Mix from Survival Garden Seeds, attracts beneficial insects and repels aphids. Peppers also do well near onions and garlic, which can deter spider mites. Avoid planting peppers near fennel or beans, as they can stunt growth.

Can basil be planted with peppers?

Yes, basil is an excellent companion for peppers. It helps repel thrips and mosquitoes, and many gardeners say it improves the flavor of peppers. Basil enjoys the same warm, sunny conditions as peppers, making them easy to pair in garden beds or containers. For more on soil preparation, see our guide on best soil for weed plant – the same principles apply to vegetables.

Does nasturtium really help peppers?

Nasturtium is a tried-and-true companion plant for peppers. It acts as a trap crop, attracting aphids away from your pepper plants. The bright flowers also lure pollinators and predatory insects. The dwarf Tip Top Mix works well in containers near peppers. Just keep in mind that nasturtium prefers poor soil, so avoid over-fertilizing it.

What should not be planted near peppers?

Avoid planting peppers near fennel, beans, and kohlrabi. Fennel secretes substances that can inhibit pepper growth, while beans and peppers both need high phosphorus and can compete. Also, keep peppers away from apricot trees (if you have them) as they share fungal diseases. For indoor setups, consider using a best grow light for microgreens to start your peppers strong.

How far apart should companion plants be from peppers?

Spacing depends on the companion plant. For low-growing plants like nasturtium and basil, place them 12–18 inches from pepper stems. Taller companions like sunflowers or corn should be at least 24 inches away to avoid shading. Good air circulation helps prevent mildew, so don’t overcrowd. For more on plant spacing, visit our Plant category page.
