Meet Culantro
A tropical herb with long, serrated leaves that taste like cilantro but ten times stronger and does not bolt in heat. Culantro is widely used in Caribbean, Central American, and Southeast Asian cuisines where cilantro flavor is desired year-round. Prefers shade and moisture, making it an excellent understory herb in tropical gardens.
When to plant Culantro
Sow culantro seeds indoors on the surface of moist seed-starting mix 8-10 weeks before transplanting outdoors. Seeds are very small; press lightly without covering, as they need light to germinate. Maintain soil temperature of 75-85°F and high humidity by covering trays with a clear dome. Germination is slow and erratic, taking 14-28 days. Keep soil consistently moist but not waterlogged. Thin seedlings to 2-3 inches apart. Transplant outdoors to a shaded, moist location after all frost danger has passed and temperatures are consistently warm.

How to grow Culantro
Culantro (Eryngium foetidum) is a tropical biennial herb often confused with cilantro but with a very different appearance and much stronger flavor. It grows as a low rosette of long, serrated, lance-shaped leaves rather than the rounded, lobed leaves of cilantro. Start seeds indoors 8-10 weeks before transplanting, as germination is slow and erratic, often taking 2-4 weeks.
Sow tiny seeds on the surface of moist seed-starting mix, pressing lightly without covering, as light aids germination. Maintain warm temperatures of 75-85°F and high humidity. Transplant seedlings to a shaded, moist location outdoors after all frost danger has passed. Space plants 8-12 inches apart.
Culantro thrives in conditions most herbs dislike: shade, heat, and high humidity. It makes an ideal understory herb in tropical gardens, growing well beneath taller plants. Unlike cilantro, culantro does not bolt in heat and produces harvestable leaves year-round in tropical climates. In temperate zones, grow as a summer annual in the most shaded, moist corner of the garden, or in containers that can be brought indoors before frost.

Culantro's best neighbours
Culantro's shade and moisture preferences make it an ideal understory companion for taller tropical plants like lemongrass, Thai basil, and banana. Plant beneath tomato cages or trellised beans where it benefits from filtered light. Culantro pairs naturally with cilantro in the garden, extending the cilantro-flavor season into hot weather when cilantro bolts. Avoid planting near fennel. The low-growing rosette habit makes it a good ground cover companion that helps retain soil moisture for neighboring plants.

Feed it well
Culantro thrives in rich, moist, well-drained soil with a pH of 6.0-7.0 and high organic matter content. Work generous amounts of compost into the planting area. Feed every 2-3 weeks with a nitrogen-rich liquid fertilizer or fish emulsion to promote lush leaf growth. Culantro is a heavier feeder than cilantro and responds well to fertile conditions. In containers, use a moisture-retentive potting mix and feed biweekly. Keep soil consistently moist but never waterlogged, as the crown is susceptible to rot.

From seed to harvest, stage by stage
Seed Germination
Culantro seeds are notoriously slow to germinate, typically requiring 14-21 days under warm, consistently moist conditions. The tiny seeds need light to germinate and should be surface-sown or barely covered with a fine layer of vermiculite. Germination rates improve dramatically when seeds are kept at 25-30°C (77-86°F) and never allowed to dry out.
Seedling Development
The first leaves are tiny, smooth-edged, and barely resemble the mature plant. Over the next few weeks, the characteristic serrated, lance-shaped leaves begin to develop. Growth is slow at this stage and the small seedlings are vulnerable to drying out and damping off. A shallow taproot system begins to establish.
Rosette Formation
The plant develops its characteristic flat rosette of long, serrated leaves radiating outward from a central crown pressed close to the ground. Leaves grow to 15-25 cm long and 3-5 cm wide, with distinctive spiny-toothed margins. The flavor intensifies as leaves mature, developing the potent cilantro-like aroma that is 8-10 times stronger than cilantro leaves.
Productive Harvest Phase
The plant reaches full productivity, continuously producing new leaves from the central crown as outer leaves are harvested. Under ideal conditions of warm temperatures, partial shade, and consistent moisture, a single plant can remain productive for several months. The deepest green leaves at this stage carry the most intense flavor and aroma.
Bolting and Seed Production
Eventually the plant sends up a stiff, erect flower stalk 20-40 cm tall bearing small cylindrical green flower heads with tiny white or pale green flowers. Once bolting begins, leaf production slows and existing leaves become tougher and more bitter. The flowers attract small beneficial insects and produce tiny seeds that can be collected for the next planting cycle.
Sow seeds on the surface of moist seed-starting mix and press gently without burying them. Cover the tray with clear plastic or a humidity dome to maintain moisture. Place in a warm location with indirect light — a heat mat set to 27°C (80°F) significantly improves germination speed and uniformity.
Caring for Culantro month by month
What to do each month for your Culantro
July
You are herePeak harvest season. Cut outer leaves regularly, always leaving the central crown intact. Culantro thrives in heat and humidity that causes cilantro to bolt within days. Provide afternoon shade if temperatures exceed 35°C (95°F). Watch for slugs and snails, which are attracted to the moist conditions culantro prefers.

Harvesting Culantro
Harvest culantro leaves once the rosette has 6-8 well-developed leaves, typically 50-60 days from sowing. Cut outer leaves at the base, leaving the growing center intact for continued production. Young leaves have the best flavor; older, outer leaves can become tough. When the plant sends up a flower stalk (a tall, spiny central spike), cut it immediately to extend leaf production. Once bolting begins, leaf flavor becomes harsh and production declines. A single culantro plant produces far more cilantro-like flavor than multiple cilantro plants.

Storage & Preservation
Culantro stores much better than cilantro due to its thicker, sturdier leaves. Wrap in damp paper towels and refrigerate in a plastic bag for up to 2-3 weeks. The robust leaves freeze well: chop and store in airtight bags or freeze in ice cube trays with water or oil. Culantro also dries better than cilantro, retaining more flavor. Dry in a dehydrator at 95°F or air-dry in a well-ventilated area. Blend fresh leaves into sofrito or recaito paste and freeze in portions for quick Caribbean cooking.

Troubleshooting Common Problems
Slow germination is the biggest challenge, often taking 2-4 weeks with erratic emergence. Use fresh seed and maintain warm, humid conditions. Bolting is triggered by long day length and stress, producing a central flower spike that ends productive leaf harvest; remove flower stalks immediately. Culantro is frost-intolerant and dies at the first freeze. The serrated leaf edges can be surprisingly sharp, so handle with care. In temperate climates, finding sufficient shade and humidity for optimal growth can be difficult.
Growing Tips
- Start seeds indoors 10-12 weeks before your last frost date. Culantro seeds are slow to germinate (14-21 days) and need light, warmth, and constant moisture. Surface-sow on fine seed-starting mix, press gently, and cover with a clear humidity dome. A heat mat set to 27°C (80°F) dramatically improves germination rates.
- Grow culantro in partial shade for the best leaf quality. This is one of the few herbs that actually prefers 50-70% shade — plants grown in full sun produce smaller, tougher, more bitter leaves and bolt much faster. The ideal spot receives morning sun and afternoon shade, or dappled light throughout the day.
- Keep the soil consistently moist but never waterlogged. Culantro is native to moist tropical forest edges and will not tolerate drought. Mulch heavily around plants with organic matter to maintain even soil moisture and keep roots cool. Drip irrigation or soaker hoses are ideal.
- Use rich, humus-heavy soil amended with plenty of compost. Culantro is a moderately heavy feeder that responds well to fertile, moisture-retentive soil with a slightly acidic to neutral pH (5.5-7.0). Sandy or clay-heavy soils should be heavily amended with organic matter before planting.
- Remove flower stalks immediately when they appear to extend the leaf harvest by several weeks or even months. Once culantro commits energy to flowering and seed production, leaf quality and quantity decline rapidly. Pinch or cut the emerging stalk at its base as soon as you notice it.
- Harvest outer leaves first, always leaving the central growing point and at least 4-5 inner leaves intact. This cut-and-come-again approach stimulates continuous new leaf production. Use a sharp knife or scissors to make clean cuts at the base of each leaf stem.
- Protect culantro from slugs and snails, which are strongly attracted to the moist, shaded conditions the plant prefers. Use copper tape barriers, diatomaceous earth, or beer traps around plantings. Check plants at dusk when these pests are most active.
- Freeze surplus culantro leaves for year-round use. Unlike cilantro, culantro retains most of its flavor when frozen. Lay individual leaves flat on a parchment-lined tray, freeze until solid, then transfer to airtight bags. Frozen leaves can be added directly to soups, stews, and sauces without thawing.
- Grow culantro as an understory companion beneath taller crops like tomatoes, peppers, corn, or trellised beans. The taller plants provide the shade culantro craves while the culantro serves as a living mulch, keeping the soil cool and moist. This maximizes garden space in small plots.
- In temperate climates, pot up a few healthy plants before the first frost and bring them indoors. Culantro grows well on a bright windowsill or under grow lights through the winter if given consistent warmth (above 15°C), humidity, and moisture. Place pots on pebble trays filled with water to increase humidity around the plants.
Pick your Culantro
Common Culantro
The standard tropical variety with long, serrated leaves and intense cilantro-like flavor. Used throughout the Caribbean and Southeast Asia.
Puerto Rican Recao
A regional selection favored in Puerto Rican cuisine for recaito and sofrito. Slightly broader leaves with concentrated flavor.
Ngo Gai (Vietnamese Culantro)
The Southeast Asian form used in Vietnamese pho, Thai larb, and Malaysian laksa. Same species, selected for tropical growing conditions.
Fresh culantro is difficult to find outside of Caribbean and Asian grocery stores, where it typically sells for $2-4 per small bunch of 8-12 leaves. In mainstream supermarkets that stock it, prices can reach $5-6 per bunch. A single packet of seeds costs $2-4 and produces 20-30 or more plants, each yielding enough leaves over the season to replace dozens of store-bought bunches. Additionally, culantro freezes exceptionally well — unlike cilantro, which loses all flavor when frozen — making it easy to preserve the summer harvest for year-round use at virtually no additional cost.

What's inside
Health Benefits
- Exceptional source of vitamin A with 6748 IU per 100g (135% DV), primarily as beta-carotene, which the body converts to retinol for maintaining healthy vision, immune defense, and cell growth — significantly higher than most culinary herbs.
- Contains documented antimicrobial compounds, including eryngial and trans-2-dodecenal, which laboratory studies have shown to be effective against food-borne pathogens including Salmonella and E. coli — suggesting that traditional use in tropical cuisines may have food safety benefits.
- Rich in anti-inflammatory compounds that traditional Caribbean and Latin American herbal medicine has employed for centuries to treat joint pain, digestive inflammation, and respiratory conditions, with modern pharmacological studies confirming measurable anti-inflammatory activity.
- Provides a meaningful amount of calcium (75mg per 100g) for a leafy herb, contributing to bone density and dental health when consumed regularly as a dietary staple — as it is throughout the Caribbean and Southeast Asia.
- Contains dietary iron (2.1mg per 100g) along with modest vitamin C that aids iron absorption, making regular culantro consumption a useful strategy for maintaining iron levels in plant-forward tropical diets.
- Traditional use as a digestive aid is supported by research showing that culantro leaf extracts can stimulate digestive enzyme activity and reduce intestinal gas — the scientific basis for its centuries-old reputation as a carminative herb across multiple tropical cultures.
Where Culantro comes from
Culantro (Eryngium foetidum) is native to the tropical regions of Central America and the Caribbean, with its center of origin believed to be in the area spanning modern-day Mexico, Belize, Guatemala, and the Greater Antilles. Wild populations still thrive throughout this region in moist, shaded forest margins, riverbanks, and disturbed habitats, where the plant grows as a biennial or short-lived perennial. Indigenous peoples of Mesoamerica and the Caribbean were using culantro as both a food seasoning and a medicinal herb long before European contact, and it remains deeply embedded in the culinary traditions of these regions today.
Following European colonization and the expansion of global trade routes in the 16th and 17th centuries, culantro was carried to tropical regions throughout the world. It arrived in West Africa through the Atlantic slave trade and subsequent commerce, quickly naturalizing and becoming adopted into local cuisines. From there, it spread to Southeast Asia via maritime trade networks, finding an eager reception in the tropical climates of Vietnam, Thailand, Malaysia, Cambodia, and Indonesia, where it became integrated into soups, salads, curries, and condiment pastes. Today, culantro is so thoroughly naturalized across tropical Asia that many locals consider it an indigenous plant.
In the Caribbean, culantro holds a cultural significance that extends far beyond its role as a seasoning. In Trinidad and Tobago, it is the cornerstone of 'green seasoning,' the aromatic paste that forms the foundation of nearly all savory cooking on the islands. In Puerto Rico, culantro is the defining herb in recaito, the green sofrito base used in countless traditional dishes from beans to rice to stews. Throughout Central America, it appears in salsas, ceviches, soups, and rice dishes. Its species name, foetidum, meaning 'stinking,' reflects the strong aroma that some find overwhelming but millions of devoted cooks consider irreplaceable.
Despite its enormous importance in tropical cuisines worldwide, culantro remains relatively obscure in temperate-climate countries, often confused with cilantro at markets and rarely stocked in mainstream supermarkets. However, growing immigrant communities from the Caribbean, Latin America, and Southeast Asia have steadily increased demand, and adventurous gardeners in temperate regions have discovered that culantro can be successfully grown as a warm-season annual or windowsill herb, bringing a taste of the tropics to northern kitchens.

Fascinating facts about Culantro
Culantro is often called 'Mexican coriander' or 'spiny coriander,' but it is botanically unrelated to cilantro (Coriandrum sativum). Culantro belongs to the family Apiaceae, genus Eryngium, while cilantro is in the same family but a completely different genus — their similar flavors are a remarkable case of convergent evolution in plant chemistry.
