Meet Mexican Tarragon
A marigold relative with leaves that taste remarkably like French tarragon, thriving in hot climates where true tarragon fails. Mexican tarragon produces small golden flowers in late summer and tolerates heat and humidity that would kill French tarragon. Use the anise-flavored leaves identically to French tarragon in sauces, vinegars, and poultry dishes.
When to plant Mexican Tarragon
Sow Mexican tarragon seeds indoors 6-8 weeks before the last frost date. Press tiny seeds onto the surface of moist seed-starting mix—they need light for germination. Maintain 20-25°C for germination in 10-14 days. Seedlings grow quickly once established. Transplant outdoors after all frost danger passes and soil warms. Can also be propagated by division of established clumps in spring or from stem cuttings taken in summer. Unlike French tarragon, Mexican tarragon sets viable seed.

How to grow Mexican Tarragon
Mexican tarragon, also called Mexican mint marigold or Spanish tarragon, is a heat-loving perennial marigold relative whose leaves taste remarkably similar to French tarragon—making it the essential tarragon substitute for hot, humid climates where true tarragon fails. Plant in full sun after all frost danger passes, spacing 30cm apart in well-drained soil.
This subtropical perennial thrives in the heat and humidity that kills French tarragon. It grows 45-75cm tall with narrow, glossy green leaves on upright stems, producing clusters of small golden-yellow flowers in late summer and autumn. In zones 8-12, it is reliably perennial; in colder zones, grow as an annual or overwinter indoors.
Provide moderate watering—Mexican tarragon is more drought-tolerant than its lush appearance suggests. Feed monthly with balanced liquid fertilizer for optimal leaf production. Pinch growing tips regularly to encourage bushy growth and delay flowering, as leaf flavor diminishes once plants bloom heavily. In its native Mexico, this herb has been used for centuries both as a culinary herb and as a medicinal tea.

Mexican Tarragon's best neighbours
As a Tagetes (marigold) family member, Mexican tarragon produces root exudates that suppress nematodes and other soil-borne pests, making it an excellent companion for tomatoes, peppers, and other nematode-susceptible crops. The golden flowers attract pollinators and beneficial insects. Plant alongside heat-loving herbs like basil and cilantro that share similar cultural requirements. The upright habit provides a good backdrop for lower-growing companion plants.

Feed it well
Grow in well-drained, moderately fertile soil with pH 6.0-7.5. Avoid heavy, waterlogged soil. Feed monthly with balanced liquid fertilizer during the growing season for best leaf production. In containers, use standard potting mix with added perlite for drainage. Mexican tarragon is adaptable to various soil types but performs best with consistent nutrition. Top-dress with compost in spring for in-ground plants.
Ideal Temperature
Hardiness Zone Compatibility
From seed to harvest, stage by stage
Seed Starting
Sow tiny seeds on the surface of moist seed-starting mix. Seeds need light to germinate, so do not cover them. Keep the medium consistently moist and warm at around 20-25°C.
Seedling Development
Seedlings emerge with narrow, lance-shaped cotyledons. True leaves develop with the characteristic opposite arrangement. Growth is slow at this stage but steady.
Vegetative Growth
The plant develops its bushy, upright form with multiple branching stems. Leaves become glossy and intensely aromatic. Root system establishes strongly during this phase.
Established Herb
Plants reach 45-75 cm in height with dense foliage. Regular harvesting promotes continuous new growth. The anise flavor is at its peak during this stage.
Flowering
Clusters of small, bright golden-yellow flowers appear at the stem tips, typically triggered by shorter day lengths in late summer and fall. Flowers are edible and attract beneficial pollinators.
Dormancy and Overwintering
In cooler climates, top growth dies back after frost. The root crown can survive mild winters with protection. In frost-free zones, the plant may remain evergreen year-round.
Mist gently rather than watering from above to avoid displacing the fine seeds.

Harvesting Mexican Tarragon
Harvest Mexican tarragon leaves throughout the growing season by cutting stem tips 10-15cm long just above a leaf node. The anise-flavored leaves are best used fresh, picked in the morning for peak essential oil content. Leaves harvested before flowering have the most concentrated flavor. The golden flowers are also edible and make attractive garnishes. In tropical climates, harvest year-round from established perennial plants.

Storage & Preservation
Fresh Mexican tarragon keeps for about one week refrigerated in a sealed bag with a damp paper towel. The leaves dry reasonably well—hang small bundles in a warm, dark area for 1-2 weeks. Dried leaves retain a good anise flavor, though less nuanced than fresh. Freeze fresh sprigs in freezer bags for convenient cooking access. Infuse fresh leaves in white wine vinegar for a tarragon vinegar that rivals the French original. Make tarragon butter for storage.

Troubleshooting Common Problems
Not cold-hardy below zone 8—treat as an annual or overwinter indoors in cold climates. Leggy, floppy growth indicates insufficient light; ensure full sun. Poor flavor usually means plants are over-watered or under-fertilized. Excessive flowering reduces leaf flavor—pinch flower buds to extend the culinary harvest. In tropical climates, plants may grow too vigorously and become woody; prune hard annually in late winter to rejuvenate.
Growing Tips
- Start seeds indoors 6-8 weeks before the last frost, pressing them onto the surface of moist mix without covering since they need light to germinate.
- Choose a planting site with full sun and well-drained soil; Mexican tarragon tolerates poor soils but struggles in waterlogged conditions.
- Space plants 30-45 cm apart to allow for their bushy, upright growth habit and ensure good air circulation around the foliage.
- Water deeply but infrequently once established, allowing the top few centimeters of soil to dry between waterings to prevent root rot.
- Pinch or cut growing tips regularly throughout the season to encourage branching and prevent the plant from becoming tall and leggy.
- Apply a light feeding of balanced organic fertilizer once a month during the active growing season, but avoid over-fertilizing which reduces essential oil concentration.
- Harvest leaves in the morning after the dew has dried for the highest concentration of aromatic essential oils and the best flavor.
- Take stem cuttings in midsummer for propagation; they root easily in moist perlite or vermiculite within two to three weeks.
- Mulch heavily around the root crown in autumn if you are in a borderline hardiness zone to help the plant survive winter and regrow in spring.
- Grow a potted specimen on a sunny windowsill during winter to maintain a fresh supply of leaves year-round in colder climates.

Where Mexican Tarragon comes from
Mexican tarragon (Tagetes lucida) is native to Mexico and Central America, where it has been cultivated and used for thousands of years. The Aztec civilization held this aromatic herb in particularly high regard, incorporating it into both their culinary and spiritual practices. They called it "yauhtli" and used it extensively as a flavoring agent in chocolate-based beverages, as a medicinal remedy for various ailments, and as a ceremonial incense during religious rituals. Spanish conquistadors documented the plant's widespread use when they arrived in the early sixteenth century, noting its importance in Aztec markets and temple offerings. The herb was traditionally associated with the rain god Tlaloc and was burned in large quantities during harvest festivals.
Following the Spanish conquest, Mexican tarragon gradually spread to other tropical and subtropical regions worldwide. European botanists classified it within the Tagetes genus in the eighteenth century, recognizing its close relationship to common marigolds. In the twentieth century, gardeners and cooks in warm climates rediscovered its value as a practical substitute for French tarragon (Artemisia dracunculus), which often fails in hot, humid conditions. Mexican tarragon thrives where French tarragon wilts, tolerating heat, humidity, and poor soils with remarkable resilience.
Today, Mexican tarragon is enjoying a renaissance among herb gardeners, permaculture practitioners, and chefs who appreciate its robust anise-licorice flavor profile. It is widely grown in the southern United States, Southeast Asia, and parts of Africa as both a culinary herb and an ornamental plant. Its dual-purpose nature, offering both edible foliage and attractive golden flowers, has made it a favorite in edible landscape designs and pollinator gardens.
