Marigold
Marigold is a bright, hardy annual flower renowned for its vivid hues and easy-growing nature. Belonging to the daisy family (Asteraceae, which also includes sunflower, zinnias, and cosmos), marigolds produce bold blooms in shades of golden yellow, orange, red, and bronze. These cheerful flowers are a staple of summer gardens and are among the most popular types of flowers for bedding and borders. Gardeners value marigolds for their long blooming season, low maintenance needs, and natural pest-repellent qualities. The flowers range from frilly carnation-like pompons to simple daisy-like single petals, offering variety in form while always delivering dazzling color. As classic yellow flowers and orange flowers, marigolds provide a burst of sunshine in any landscape. They thrive across the United States as warm-season annuals, adding continuous color from late spring until the first frost. In addition to their ornamental appeal, marigolds have a rich history and cultural significance, which further cements their status as garden favorites.

🌱 Taxonomy and origin
Botanically, marigolds belong to the genus Tagetes, which comprises about 50 species of flowering plants native to the New World. The common marigolds grown in gardens are primarily African marigold (Tagetes erecta) and French marigold (Tagetes patula), along with the petite signet marigold (Tagetes tenuifolia). Despite their names, African and French marigolds both originate from the Americas. African marigold – also called Aztec or American marigold – is native to Mexico and Central America and was cultivated by the Aztecs for centuries. French marigold, likewise of Central American origin, was later bred in Europe (notably France) into the compact varieties we know today. These plants were introduced to Europe in the 16th century by Spanish explorers and quickly spread worldwide due to their beauty and adaptability. The genus name Tagetes honors “Tages,” an Etruscan deity said to have sprung from freshly plowed earth, alluding to the ease with which marigolds self-seed and pop up in cultivated soil. The common name “marigold” comes from “Mary’s gold,” originally referring to the Calendula (pot marigold) in medieval times, but now broadly applied to Tagetes as well. In their native habitats, marigolds grow in sunny, warm regions. Over time they have naturalized in many countries and become integral to cultural traditions – from Mexican Día de los Muertos altars adorned with golden sunflower-like marigold blooms to Indian wedding garlands made of vibrant orange strings of blossoms. Today’s marigolds blend rich historical roots with modern horticultural breeding, resulting in an array of cultivars that continue to enchant gardeners around the globe.
🌸 Bloom time
Marigolds are prolific bloomers that brighten gardens for an extended period. Their bloom time typically begins in late spring or early summer, shortly after warm weather sets in. Once flowering starts, marigolds continue to bloom vigorously throughout summer and into fall. In most climates, they will keep producing new buds and flowers non-stop until halted by cold weather or frost. Regular deadheading (removing spent blooms) helps marigolds channel energy into new flower production, thereby extending the blooming season even further. With attentive care, these annuals can provide a continuous display of color for several months on end. Marigold flowers are also known for withstanding the intense heat of mid-summer. They thrive in warm conditions that might cause other flowers to fade. In fact, the hotter the summer sun, the more profusely marigolds tend to bloom, provided they have adequate moisture. By late fall, as night temperatures start to drop, blooming will slow and eventually cease once frost arrives. Gardeners in frost-free regions may enjoy blooms year-round, but in temperate areas marigolds are treated as seasonal showstoppers from spring through autumn. Overall, the lengthy and abundant bloom time of marigolds is one of their greatest assets, ensuring that gardens stay lively with bright orange and yellow blossoms all season long.
📏 Height and spread
The size of marigold plants can vary widely depending on the type and cultivar. In general, marigolds are bushy annuals with a mounded form. Dwarf French marigolds are the smallest, typically reaching only about 6 to 12 inches tall (15 to 30 cm) and spreading 6 to 8 inches (15 to 20 cm) wide. These compact varieties are ideal for edging and containers. By contrast, African marigolds are taller and more upright, with heights ranging from 1 to 3 feet (30 to 90 cm) and a spread of 1 to 2 feet (30 to 60 cm) per plant. Their robust stature and large flower heads make African marigolds excellent for background plantings or cutting gardens. Signet marigolds, a separate type, are low-growing (8 to 12 inches tall) but tend to spread into dense, ferny mats of foliage studded with many small blooms. Intermediate marigold hybrids (crosses between African and French types) often grow about 12 to 18 inches tall (30 to 45 cm), combining a mid-range height with prolific blooming. Regardless of type, marigolds have a full, branching habit with lush green pinnate leaves. Each plant can fill out nicely if given enough space. Crowding should be avoided because good air circulation around each mound helps prevent disease. When planting, allow adequate spacing: about 8 to 10 inches apart for French marigolds and 12 to 16 inches for African marigolds is recommended. Proper spacing ensures each marigold can reach its full height and spread, resulting in a healthier, more floriferous display.
☀️ Light
Marigolds flourish in bright sunlight and prefer full sun exposure for best growth and flowering. “Full sun” means at least 6 to 8 hours of direct sunlight per day. In open sunny beds, marigolds develop sturdy stems and abundant blooms. They are naturally adapted to sunny, warm environments and will perform best when not shaded by taller plants or structures. While marigolds can tolerate partial shade for a few hours a day, too much shade will lead to fewer flowers and leggy, stretched growth as the plants reach for more light. In dense shade, marigolds may fail to bloom altogether. For this reason, it’s advisable to plant marigolds in locations that receive morning and afternoon sun. In very hot climates or peak summer heat, marigolds can handle the intensity of the sun. In fact, they excel in high heat as long as soil moisture is sufficient. However, providing a bit of light afternoon shade in extreme heat (such as in desert regions) can prevent scorching of blooms and foliage. Generally, though, sun-loving marigolds are at their best in open, unshaded areas. Ensuring plenty of sunlight not only boosts flower production but also helps keep plants dry and less prone to fungal diseases. Whether grown in garden beds or in pots on a sunny patio, marigolds should be placed where they will soak up ample sunshine every day to maintain their vigor and constant blooming.
💧 Water
Proper watering keeps marigolds healthy and flowering profusely. These annuals prefer moderate moisture levels and well-drained conditions. After planting marigolds, water them thoroughly to settle the soil around the roots. During the first few weeks as they establish, keep the soil evenly moist (but not waterlogged) to encourage strong root development. Once established, marigolds are relatively drought-tolerant compared to thirstier flowers, but they still perform best with consistent watering. In general, aim to provide about 1 inch of water per week, whether from rainfall or irrigation. In hot summer weather, especially in containers or sandy soils, marigolds may need more frequent watering (every few days) as the topsoil dries out. Always water deeply at the base of the plant, soaking the root zone, rather than shallow sprinkling. Deep watering encourages roots to grow downward and strengthens the plant’s drought resilience. It’s also wise to water in the morning so that any moisture on the leaves can dry quickly in the sun. This practice helps minimize the risk of foliar diseases. Avoid overhead watering in the evening, which can leave foliage damp overnight and lead to problems like mildew or rot. Marigolds do not like to sit in soggy soil. If drainage is poor, their roots can suffocate and rot. Thus, good drainage is as important as the water itself. With an inch of water, a week and slightly dry intervals between waterings, marigolds will reward you with vigorous growth and continuous blooms.
🌍 Soil and pH
Marigolds are not very fussy about soil and will grow in a range of soil types, but they do best in well-draining, moderately fertile ground. An ideal soil for marigolds is a loose, loamy soil enriched with organic matter like compost. Good drainage is essential because marigold roots sitting in waterlogged, heavy clay can develop root rot. Before planting, it’s beneficial to loosen the top 6 inches of soil and mix in compost or aged manure to improve aeration and fertility. While marigolds can tolerate somewhat lean or poor soils better than many ornamentals, a bit of nutrients helps them bloom their best. However, avoid over-fertilizing (especially with high-nitrogen fertilizers), as excessive fertility can produce lush foliage at the expense of flowers. In terms of soil pH, marigolds prefer a slightly acidic to neutral soil. A pH in the range of roughly 6.0 to 7.0 is ideal for nutrient availability. They can tolerate mildly alkaline conditions up to about pH 7.5, and also handle mildly acidic soil, but very acidic soil (below pH 5.5) may cause issues. In strongly acidic soils, marigold leaves sometimes develop a bronze or yellowish speckling due to micronutrient imbalances (such as manganese or iron toxicity that occurs at low pH). If your garden soil is extremely acidic, adding lime can raise the pH to a marigold-friendly level. Conversely, if soil is too alkaline, incorporating peat moss or sulfur can gently lower the pH. Overall, as long as the ground is reasonably fertile, well-drained, and not extreme in pH, marigolds will adapt and thrive. They are forgiving plants that can brighten almost any garden soil with the right basic preparation.
❄️ USDA hardiness
Marigolds are frost-sensitive plants, generally grown as annuals in all climate zones. They are capable of thriving during the growing season in USDA zones 2 to 11, but cannot survive hard freezes. In practice, gardeners in cold regions (zones 2 through 7) sow or transplant marigolds each spring after the danger of frost has passed, enjoy them over the summer, and then the plants die with the autumn frosts. In warmer parts of the country, such as the Deep South and coastal West (zones 8 to 11), marigolds have a longer growing window and can be planted earlier and kept later in the year. In fact, in frost-free tropical or subtropical climates, marigolds may persist year-round or reseed themselves, effectively acting as perennials. Some specific marigold species are true perennials in warm zones. For example, the bushy Tagetes lemmonii (Mexican marigold) is a shrubby perennial hardy to about zone 8. Likewise, Tagetes lucida (Mexican tarragon) can overwinter in mild climates. But the common French and African marigolds cannot tolerate any significant frost. Even a light freeze will blacken their foliage and kill them to the ground. Thus, their “hardiness” is limited to mild winter areas. For most gardeners, it’s best to treat marigolds as annual bedding plants that complete their life cycle in one season. Start them after last frost in spring, enjoy them until frost in fall, and collect seeds or plan to replant the following year. Recognizing that marigolds are tender will prevent any disappointment when winter arrives. When planning a garden, use marigolds freely in summer displays knowing they will need to be replanted each year outside of the warmest U.S. zones.
🌼 Propagation and longevity
Marigolds are among the easiest garden flowers to propagate, especially from seed. The most common way to grow new marigold plants is to start them from seeds, either indoors or by direct sowing in the garden. Marigold seeds are slender, black-and-white striated achenes that germinate quickly under the right conditions. For an early start, seeds can be sown indoors 4 to 6 weeks before the last expected spring frost. Keep them in a warm environment (around 70°F or 21°C) and evenly moist. Under these conditions, seedlings usually sprout within a week. Young marigold seedlings grow rapidly and can be transplanted outdoors once the weather has warmed and they have at least two sets of true leaves. Alternatively, you can direct-seed marigolds outdoors after the last frost date by planting the seeds about ¼ inch deep in prepared soil. Thin the seedlings to proper spacing as they grow. Marigolds mature fast – many varieties will begin flowering just 8 to 10 weeks from sowing. This quick turnaround makes them a favorite for children’s gardening projects and new gardeners. Besides seeds, marigolds are also widely available as nursery-grown transplants, which can simply be set into the garden for instant color. Other propagation methods (like cuttings or division) are not commonly applied to marigolds, since seeds are so convenient and reliable. In terms of longevity, most marigolds are true annuals, meaning each plant lives only one growing season. They sprout, bloom, set seed, and die within the year. However, marigolds often self-sow: if spent flowers are left on the plant to form seeds, those seeds may drop and germinate the next season in the same area, giving the impression of the marigolds “returning.” In warm climates without frost, certain marigold plants can survive and bloom for multiple years, but even in such cases they tend to decline after a couple of years, so gardeners usually replant them for best results. Collecting marigold seeds from open-pollinated (non-hybrid) varieties at the end of the season is an easy way to propagate your favorite blooms for the next year. Simply allow some flowers to dry on the plant, harvest the dried seed heads, and store the seeds in a cool, dry place for spring planting. By propagating from seed and understanding their short life span, you can enjoy marigolds year after year with minimal expense and effort.
👃 Fragrance
Marigolds are known for their distinctive fragrance, though it is quite different from the sweet scent of flowers like roses or jasmine. The aroma of marigolds is often described as pungent, musky, or herbal. It emanates mostly from the leaves and stems rather than from the blossoms themselves. When a marigold plant is brushed against or the foliage is crushed, it releases a strong spicy odor that some people find off-putting while others associate it with the quintessential “scent of the garden.” The flowers of most French and African marigolds have only a mild fragrance, overshadowed by the pungency of the greenery. One exception is the signet marigold (Tagetes tenuifolia), whose small single flowers have a pleasant, citrusy scent and flavor. Indeed, signet marigold blossoms are edible and often used as a garnish with a tarragon-like, lemony taste. Marigold foliage’s bold scent is not just a random trait. It serves to deter certain insects and browsing animals. Many gardeners appreciate that the strong smell tends to repel deer and rabbits, making marigolds useful as a natural border to protect more delicate plants. In addition, compounds from marigold (Tagetes) are extracted for use in perfumery and flavoring. The essential oil of Tagetes has a fruity yet marigold-like note and is used in some perfumes and tobacco flavoring, albeit in tiny amounts due to its potency. While you won’t likely grow marigolds for a delightful floral perfume in the garden, their fragrance does play a role in integrated pest management and adds an earthy, nostalgic scent to the summer garden.
⚠️ Toxicity and pet safety
Gardeners with pets and children are often concerned about plant toxicity. Marigolds (Tagetes species) are generally considered safe and non-toxic to humans and animals, with a few minor caveats. Unlike some ornamental plants, marigolds do not contain deadly poisons. The ASPCA lists marigolds as not highly toxic to dogs or cats. Ingesting the plant or flowers is unlikely to cause serious harm, though it might result in mild gastrointestinal upset (vomiting or diarrhea) if a pet or person eats a large amount. The sap of marigolds, like many in the daisy family, can be a skin irritant for some individuals. Gardeners with sensitive skin might experience redness or rash after handling marigold foliage, especially on sunny days (as the compounds can cause a mild photodermatitis). It’s wise to wear gloves if you notice skin irritation when pinching or pruning marigolds. In terms of pet safety, the pungent taste of marigold usually deters dogs and cats from consuming much of the plant. If they do nibble, effects are typically limited to minor oral or stomach irritation. Importantly, note that “marigold” can also refer to Calendula, the pot marigold, which is actually a different plant (genus Calendula). Calendula is likewise non-toxic and is even used as an herbal remedy and edible flower. In fact, signet marigolds (Tagetes) have edible petals too, so toxicity is very low. While Tagetes marigolds are safe, it’s always good practice to discourage pets from chewing on any ornamentals, just to prevent any tummy troubles. Overall, you can plant marigolds in your garden without significant worry about poisoning risks. They are a pet-friendly choice for adding color. Just be aware of the potential for mild irritation, and you’ll find marigolds to be a generally harmless addition to the home landscape.
🌿 Vase life
Marigolds make interesting and long-lasting cut flowers if prepared correctly. When harvested at the right stage, marigold blooms can have a vase life of approximately 7 to 10 days. African marigolds, with their large sturdy blossoms on long stems, are particularly popular for flower arrangements and displays. To maximize longevity, it’s best to cut marigold stems in the cool of early morning or evening, choosing flowers that are just half to three-quarters open. Using a sharp, clean knife or pruners, cut above a leaf node to encourage the plant to branch. Immediately place the cut stems in water to prevent wilting. Before arranging, strip off any leaves that would sit below the water line in the vase, as marigold foliage decomposes quickly in water and can cause bacterial buildup. The water in the vase should be changed every day or two, since marigolds exude a sap that can cloud water and produce a strong odor if left stagnant. Adding floral preservative to the vase water will further extend freshness by nourishing the blooms and limiting bacteria. Properly conditioned marigold flowers will hold up well for about a week, maintaining their bold color. Their uniquely musky scent will be noticeable in indoor arrangements – some people enjoy the earthy fragrance, while others might find it a bit overpowering. If you are preparing marigolds for a special event (like using garlands or bouquets of marigolds, which is common in certain cultural celebrations), keep them in a cool environment prior to display. Marigolds respond well to cool storage, and the blooms can even be held for a short period in a floral cooler at around 40°F (4°C) to prolong their vase life. Overall, with simple care, cut marigolds can be a vibrant and eye-catching component of bouquets, centerpieces, or floral decorations that last for many days.
🐛 Pests and diseases
Marigolds have a reputation for repelling pests, but they are not completely pest-proof themselves. On the positive side, marigolds are seldom troubled by large herbivores – deer and rabbits typically avoid them due to the strong scent of the foliage. Also, marigolds are known to suppress soil-dwelling pests like nematodes. French marigolds in particular produce compounds in their roots that can reduce certain nematode populations in the soil, which is why marigolds are sometimes used as a cover crop or companion plant in vegetable gardens. However, marigolds can attract or fall victim to several common garden insects. Aphids often cluster on new growth and flower buds, sucking sap and potentially spreading viruses. Spider mites can become an issue in hot, dry weather, causing speckled, yellowed leaves and fine webbing on the undersides of foliage. Whiteflies and thrips may also feed on marigolds, especially in greenhouse conditions or dense plantings. Caterpillars (such as cabbage loopers or armyworms) occasionally chew on marigold leaves as well. Another surprising pest drawn to marigolds is the slug or snail. These mollusks find young marigold seedlings quite delectable and can skeletonize leaves or clip off seedlings overnight. Japanese beetles are known to nibble on marigold blossoms in some regions, attracted by the bright petals. While these pest issues can occur, marigolds are fairly resilient. Most insect infestations can be managed by hand-picking, spraying plants with a jet of water, or using insecticidal soap on heavy aphid or mite colonies.
When it comes to diseases, marigolds are generally trouble-free if given proper conditions, but a few problems do appear on occasion. In humid or wet weather, fungal diseases like powdery mildew (a white powdery coating on leaves) or leaf spot can develop, particularly if plants are overcrowded and lack air circulation. A common issue for marigolds in prolonged damp conditions is gray mold (Botrytis), which may cause fuzzy gray rot on spent flowers or leaves. Stem and root rot caused by soil fungi can occur if soil drainage is poor or if plants are overwatered. Seedlings are susceptible to damping off (a soil-borne fungal disease that causes stems to collapse) if started in unsanitary conditions. Marigolds can also be affected by aster yellows (a phytoplasma disease) and various plant viruses (such as tomato spotted wilt virus or cucumber mosaic virus) transmitted by sap-sucking insects. These cause stunted, distorted growth or unusual color patterns on leaves and flowers. There is no cure for viral or phytoplasma infections. Infected plants should be removed to prevent spread. The good news is that many of these issues are relatively uncommon and can be minimized. Plant marigolds in well-drained soil and full sun to keep them dry and healthy. Avoid overhead watering and space plants appropriately to reduce fungal problems. Remove spent blooms and any diseased tissue promptly. Healthy marigolds grown in the right conditions will have few serious problems and will often outgrow minor pest damage. Overall, marigolds remain one of the more pest- and disease-resistant flowers for the garden, which is part of their enduring appeal.
FAQ
Are marigolds annuals or perennials?
Most marigolds are grown as annuals, meaning they complete their life cycle in one growing season. In any climate with cold winters or frost, marigold plants will die at the end of the season and need replanting next year. However, in warm regions with no frost (roughly USDA zones 9 to 11), marigolds can survive year-round and potentially act as short-lived perennials. There are also a few perennial marigold species like Tagetes lemmonii (Mexican marigold) that can live for multiple years in mild climates. Generally, though, plan on treating French and African marigolds as annual bedding plants that you replant each spring after the last frost.
Can marigolds grow in pots or indoors?
Yes, marigolds perform very well in containers, making them great candidates for pots, planters, and window boxes. Choose a pot with drainage holes and use a good-quality potting mix so excess water can drain. Place potted marigolds in a spot that receives full sun for most of the day, such as a south-facing patio or balcony. With regular watering (containers dry out faster than garden soil) and occasional feeding, marigolds will bloom continuously in pots just as they do in the ground. As for growing indoors, marigolds can be started inside from seed or grown on a sunny windowsill, but they really need a lot of light to bloom well. Unless you have a bright greenhouse-like indoor space or supplemental grow lights, marigolds may stretch and produce fewer flowers indoors. They generally do better outdoors where they can get ample direct sunlight and good airflow. If starting seeds indoors, move the seedlings outside when weather permits for the best results.
Do marigolds really repel pests and mosquitoes?
Marigolds have a reputation for deterring pests, but their effect is somewhat limited. The strong scent of marigold foliage can help confuse or repel certain insects to a small extent – for example, some gardeners find that whiteflies or aphids are less prevalent near marigolds, and the smell may discourage mosquitoes in the immediate vicinity. Marigolds also produce natural compounds that are toxic to many soil nematodes, which is why planting marigolds as a cover crop can reduce nematode infestations in vegetable beds. However, simply planting a few marigolds among your vegetables will not create an insect-free zone. Pests like caterpillars, beetles, or aphids will still attack if conditions favor them. In fact, marigolds themselves can attract slugs and spider mites. Consider marigolds as a helpful companion plant – they can draw in pollinators and possibly deter some pests or serve as a trap crop – but they are not a foolproof pest solution. For mosquitoes, marigolds contain compounds that bugs dislike, yet you would need a lot of marigold plants and even then, the protection is minimal. It’s more effective to use marigolds in combination with other integrated pest management strategies rather than relying on them alone for pest control.
How do I collect and save marigold seeds?
Saving marigold seeds is easy and rewarding. Toward the end of the blooming season, allow some healthy marigold flowers to remain on the plant and dry out instead of deadheading them. As the flower heads turn brown and papery, they are maturing seeds. Once fully dry, you can pluck off these spent blossoms and crack them open over a tray or paper towel. Inside, you’ll find a cluster of slender, pointed seeds that are black on one end and beige or white on the other. Gently separate and clean the seeds, removing any chaff. It’s best to do this on a dry day to avoid trapping moisture with the seeds. Store your collected marigold seeds in a paper envelope or small glass jar in a cool, dry place until spring. Be sure to label them with the variety or color. Marigold seeds remain viable for a couple of years when stored properly. When you sow saved seeds the next year, keep in mind that if the parent plants were hybrid varieties, the offspring may not look exactly the same as the original plant (hybrids don’t come true to type from seed). Open-pollinated or heirloom marigolds will yield seedlings very similar to the parent. By collecting your own seeds, you can enjoy your favorite marigolds year after year without having to buy new seed packets, and you can even share or trade seeds with fellow gardeners.
Are marigolds safe for pets and people?
Yes, marigolds are generally safe to grow around pets and humans. They are not poisonous to dogs, cats, or people if touched or ingested. At most, eating marigold leaves or flowers could cause some mild stomach upset or irritation, but serious symptoms are very unlikely. Many people actually eat marigolds in small amounts – for example, signet marigold petals are used in salads, and marigold extracts are used as food coloring agents – so they are quite benign. That said, the plant’s sap can cause mild skin irritation for some individuals, so if you have a pet that likes to chew plants, you may notice a bit of drooling or pawing at the mouth, or a person with sensitive skin might get a slight rash from handling the plant. These effects are minor and transient. It’s always a good idea to discourage pets from grazing on ornamentals as a general rule, but you can rest assured that marigolds pose no serious toxicity hazard. Compared to truly toxic garden plants (like lilies or foxglove), marigolds are a pet-friendly choice. If you have concerns, you can consult the ASPCA’s list of toxic and non-toxic plants, which classifies marigolds as largely non-toxic. As with any plant, basic supervision and moderation are key – but marigolds are about as safe as it gets for a flowering garden annual.
What is the difference between African and French marigolds?
African and French marigolds are two popular groups of marigold, and they differ in size and flower style. African marigolds (Tagetes erecta) are the larger type – these plants can grow 2 to 3 feet tall and have big, full flower heads that are often fully double (resembling carnation or pom-pom shapes). African marigold blooms can be 3 to 4 inches across and tend to come in shades of yellow, gold, and orange. They are sometimes called American or Aztec marigolds and are great for making a bold statement in flower beds or for use as cut flowers. French marigolds (Tagetes patula), on the other hand, are smaller and bushier. They typically reach only about 8 to 18 inches in height. Their flowers are also smaller, usually 1 to 2 inches across, but they are very colorful. French marigold blooms often have bi-color petals or intricate crested centers, and they range in color from yellow and orange to deep reddish-brown combinations. French marigolds also tend to bloom a bit earlier and more profusely over the season than the larger African types. Additionally, French marigolds handle rainy weather and humid conditions better – their petite blossoms bounce back after rain, whereas the heavy double blooms of African marigolds can sometimes rot or topple in excessive moisture. Gardeners often use French marigolds for edging and containers, and African marigolds for background plantings. Both types are easy to grow and share the same general care, and both will give your garden that signature marigold charm in different scales.
Interesting tips
- Deadhead regularly: Removing faded marigold flowers promptly will encourage the plants to produce even more blooms. Pinch or snip off spent blossoms to keep the plant’s energy directed toward new buds, ensuring a brighter display for a longer time.
- Great for companion planting: Marigolds are excellent companions in vegetable gardens. French marigolds in particular help suppress root-knot nematodes in the soil, benefiting crops like tomatoes. Planting marigolds around vegetable beds can also confuse or divert some pests, all while adding color to the garden.
- Deer and rabbit resistant: Thanks to their pungent aroma, marigolds are seldom bothered by deer or rabbits. If you have trouble with these animals eating your flowers, try lining your garden borders with marigolds as a natural deterrent. Their strong scent is unappealing to many four-legged garden intruders.
- Edible and useful blooms: Marigold flowers aren’t just for show – the petals of certain marigold varieties are edible. Signet marigolds (such as the orange ‘Tangerine Gem’ or yellow ‘Lemon Gem’) have a citrusy flavor and can be used as a colorful garnish in salads. Marigold petals have also been used as a natural dye and even as an ingredient in poultry feed to deepen egg yolk color.
- Cultural significance: In Mexico and Central America, marigolds (especially Tagetes erecta) are famously known as “flowers of the dead” and are used in abundance during Day of the Dead celebrations to honor departed loved ones. In India and South Asia, marigolds are woven into garlands for weddings and festivals, symbolizing auspiciousness and the power of the sun. Growing marigolds in your garden can thus connect you to a rich tapestry of cultural traditions while you enjoy their beauty.
