Culantro

Eryngium foetidum

herb

Culantro is a tropical herb with flat, serrated leaves that closely resembles cilantro but has a more robust, pungent flavor. Native to Central and South America and the Caribbean, it thrives in warm, humid conditions and provides a longer harvest window than cilantro. The leaves are commonly used in Latin American and Caribbean cuisine as a substitute for or complement to cilantro.

Growth Stages

1

Germination

10-14 days

Tiny seedlings emerge with simple leaves; seeds require warm temperatures (70-80°F) to germinate.

Keep soil warm and consistently moist. Germination takes 10-14 days. Thin seedlings to proper spacing once they have 2-3 true leaves.

2

Seedling to Juvenile

2-3 weeks

Young plants develop characteristic flat, serrated leaves arranged in a basal rosette; growth is steady as roots establish.

Maintain consistent moisture and warmth. Provide bright, indirect light. Begin feeding with diluted balanced fertilizer every 2-3 weeks.

3

Vegetative Growth

4-8 weeks

Plant forms a dense rosette of 8-12 inch long, dark green serrated leaves. Foliage is bushy and full, ready for regular harvesting.

Pinch back growing tips to encourage bushier growth. Begin regular leaf harvesting from outer leaves. Maintain consistent moisture and humidity. Feed every 2-3 weeks with balanced fertilizer.

4

Flowering (Optional)

Variable; occurs in warm conditions

If left unharvested, plant sends up thin flowering stems with small, white to pink flowers in globe-shaped clusters. Flowering reduces leaf quality.

Pinch off flower stalks to promote continued leaf production if harvesting for culinary use. Allow to flower only if seed collection is desired.

5

Seed Production

3-4 weeks

Flowers are followed by small, spiky seeds that mature over several weeks; plant may decline after heavy flowering.

Allow flowers to fully mature if collecting seeds. Save seeds from healthy plants in dry conditions. Seeds remain viable for 1-2 years.

Common Pests

  • Spray with neem oil or insecticidal soap; strong water spray to dislodge; encourage beneficial insects like ladybugs.

  • Increase humidity; spray with water misting; use neem oil or miticide if severe. Keep foliage dry to reduce mite activity.

  • Yellow sticky traps; neem oil spray; insecticidal soap; improve air circulation.

  • Remove by hand or with alcohol-soaked cotton swab; spray with insecticidal soap or neem oil.

  • Remove affected leaves; improve air circulation; avoid overhead watering; apply fungicide if severe.

Uses

🍳

Caribbean & Latin American Cooking

Culinary

Culantro is a staple herb in Caribbean, Puerto Rican, Dominican, and Latin American cuisines. It adds a stronger, more pungent cilantro-like flavor to sofrito, salsas, soups, stews, rice dishes, and marinades. [source]

Harvest Tips

Begin harvesting outer leaves once the plant reaches 6-8 inches tall, typically 40-50 days after planting. Pinch or cut leaves from the outer edges, working inward, allowing the center to continue growing. Harvest regularly to promote bushier growth and prevent flowering. Culantro produces leaves continuously for 6-12 months in ideal conditions. Morning harvest provides the best flavor and freshness. Leaves can be used fresh or dried.

Fun Facts

  • 🌱 Culantro is actually more closely related to eryngo (sea holly) than to cilantro, despite its culinary similarity and shared name meaning 'resembling cilantro' in Spanish.
  • 🌱 In some Caribbean regions, culantro is called 'cilantro' or 'shadow benni,' and locals prefer it to standard cilantro due to its superior heat and humidity tolerance, making it the more practical choice for tropical gardens.
  • 🌱 Culantro can produce harvestable leaves for 6-12 months or longer in warm climates, far exceeding cilantro's quick bolt-to-seed cycle, making it invaluable for year-round tropical herb gardening.
