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 (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.

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.

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.

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.

Culantro is essential in Caribbean cooking, forming the base of Puerto Rican recaito and sofrito alongside peppers and garlic. Use in Trinidadian green seasoning, Jamaican jerk marinades, and Latin American soups and stews. In Southeast Asian cuisine, add to Vietnamese pho, Thai larb, and Malaysian laksa. The intense flavor means you need far less culantro than cilantro. Unlike cilantro, culantro holds up to cooking and can be added early in the process without losing its punch.
