Quick answer: Culantro (Eryngium foetidum) is a warm-climate herb that can be started in containers. For the current The Rike seed listing, the product directions call for surface sowing, 75–85°F warmth and about 14–21 days for germination. Those exact numbers are product-specific guidance, not a universal guarantee. Seed lot, moisture, temperature and growing conditions can shift emergence.
Kew accepts Eryngium foetidum as the botanical species commonly called culantro. It is different from cilantro/coriander, even though the two herbs can be used in some of the same cuisines. For a fast comparison, see Cilantro vs Culantro: Pick the Right Herb Fast.
Culantro and cilantro are different herbs, so their germination and growing habits should not be treated as identical.
The current product directions specify sowing on the surface rather than burying the seed deeply. Press the seed gently into a fine, moist seed-starting medium, then keep the surface from drying hard during the germination period. If you cover the container to slow moisture loss, allow some air exchange and remove the cover after seedlings emerge.
The exact temperature and timing shown here come from the current product guidance; real emergence can vary.
UF/IFAS describes culantro as well suited to warm conditions and notes that it can be grown in the ground or in containers. Keep the germination mix evenly moist but not waterlogged. Once seedlings are established, filtered light or partial shade can help maintain leafy growth, especially in hot weather.
After emergence, shift the goal from simply keeping seed moist to balancing light, airflow, moisture and drainage.
For ongoing container care, shade, watering and harvest, continue with How to Grow Culantro in Pots.
The Rike currently carries 3,000 Culantro Seeds. Use the live product page for the current pack details, inventory and sowing directions.

If culantro seeds are not germinating
- Surface dried out: very small seeds can fail when the top layer repeatedly dries during germination.
- Mix stayed saturated: excess water can reduce root-zone air and encourage seedling problems.
- Temperature swung widely: compare the actual seed-zone temperature with the current product guidance instead of relying on room temperature alone.
- Not enough time: the product’s 14–21 day range is a guide, not a deadline.
