Cilantro and culantro share a flavor and a chunk of their names, but they are two very different plants with very different growing habits. The short answer: if you garden in a cool or temperate climate and want quick, soft leaves for salsa and garnish, grow cilantro. If you garden somewhere hot and humid where cilantro bolts in a week, grow culantro instead. It delivers the same citrusy, soapy-to-some flavor in a far tougher, longer-lasting plant. This guide breaks down exactly how they differ, what each one needs, and how to decide which belongs in your garden, or whether you should simply grow both.
Key Takeaways
- Cilantro (Coriandrum sativum) is a fast, cool-season annual with soft lacy leaves; it bolts in heat above 75°F.
- Culantro (Eryngium foetidum) is a heat-loving biennial with long, serrated, leathery leaves that tolerates 90°F+ without flowering.
- Flavor is similar, but culantro is roughly 3–4x stronger, so use about a quarter as much.
- Cilantro suits USDA zones everywhere as a spring/fall crop; culantro thrives in zones 8–11 outdoors or as a container plant elsewhere.
- For year-round supply in a hot climate, culantro wins; for delicate fresh garnish and coriander seed, cilantro wins.

Cilantro: The Fast, Familiar Cool-Season Herb
Cilantro is the herb most American cooks already know. It is the fresh, soft-leaved plant whose seeds, once dried, become coriander. Botanically it is Coriandrum sativum, a member of the carrot family (Apiaceae), and it behaves like a fast annual: sow seed, harvest in three to four weeks, and watch it flower and set seed not long after. That speed is both its charm and its frustration.
Growing conditions
Cilantro is a cool-season crop. It germinates best at soil temperatures of 55–68°F and grows happily while air temperatures sit between 50 and 75°F. The moment daytime highs push past 75–80°F, or once days lengthen in early summer, the plant reads the signal to reproduce and bolts, sending up a flower stalk and turning the leaves bitter and feathery. In most of the US this means cilantro is a spring and fall crop, not a summer one.
Sow seeds directly where they will grow, because cilantro has a taproot and resents transplanting. Plant seeds about a quarter-inch deep and an inch apart, thinning to 4–6 inches. Keep the soil consistently moist and give the plants full sun in cool weather or light afternoon shade as temperatures climb. To stretch the harvest, succession-sow a fresh pinch of seed every two to three weeks from early spring through the cool side of summer, then again from late summer into fall. A row that started in March can be backed up by another in mid-April and a third in late August.
Harvest, flavor, and the bolting problem
Snip outer leaves once plants are 4–6 inches tall, taking no more than a third at a time so the plant keeps producing. The flavor is bright, citrusy, and grassy, the classic note in salsa, guacamole, pho, and chutney. Some people taste soap instead; that is a genuine genetic difference in how certain people perceive the plant’s aldehydes, and it applies to culantro too.
When bolting comes, lean into it: let some plants flower (the blooms feed pollinators) and set seed. Those round seeds are coriander, which you can harvest dry for the spice rack or save to resow. So a single cilantro planting gives you two crops, leaf and seed, even if the leaf window is short. If you want soft leaves all summer in a hot region, though, cilantro will fight you, and that is exactly where culantro takes over.
Culantro: The Heat-Proof Tropical Cousin
Culantro (Eryngium foetidum) goes by many names, recao, shadow beni, ngo gai, sawtooth herb, and Mexican coriander, which hints at how widely it is used across the Caribbean, Latin America, and Southeast Asia. It is in a different family (it is a sea-holly relative) and looks nothing like cilantro: instead of soft lacy sprigs, it forms a flat rosette of long, narrow, leathery leaves with serrated, almost saw-toothed edges, hence “sawtooth herb.”
Growing conditions
This is a tropical biennial, and it loves the heat that kills cilantro. It performs best at 75–95°F and grows year-round outdoors in USDA zones 8–11. Unlike cilantro, it actually prefers partial shade, especially in intense sun; deep shade keeps the leaves larger, more tender, and slower to flower. Give it rich, consistently moist, well-draining soil. Culantro germinates slowly and erratically, often taking two to three weeks, and the tiny seeds need light to sprout, so press them onto the surface rather than burying them. Soil temperatures around 75–85°F speed things along.
Outside zone 8, grow culantro in containers and bring it indoors before frost; it cannot survive freezing. A pot on a warm, bright windowsill or under a grow light keeps it producing through winter in cold climates. Because it is naturally a shade plant, it adapts to indoor light better than many herbs.
Harvest, flavor, and longevity
Harvest culantro by cutting the outer leaves at the base, the way you would harvest leaf lettuce or parsley, leaving the central crown to keep generating new growth. A single well-tended plant can produce for many months. The big payoff is bolt resistance: where cilantro lasts four to six weeks, culantro holds its useful rosette through an entire hot season. When it does eventually send up a spiny flower stalk in its second year, cut it off to push the plant back into leaf production.
Flavor-wise, culantro is the same family of citrus-cilantro notes but dialed up sharply, often described as three to four times stronger and more pungent. Because the leaves are tougher, culantro shines in cooked dishes, sofrito, stews, curries, and braises, where it holds up to heat far better than delicate cilantro, which fades when cooked. As a rule of thumb, substitute about one culantro leaf for several sprigs of cilantro.
Side-by-Side: Which Should You Grow?
The decision comes down to climate first, use second. Match the plant to your conditions and you will have a far easier time than fighting nature.
- Cool or temperate climate (zones 3–7): Grow cilantro in spring and fall and succession-sow. Grow culantro only in a pot you can bring indoors.
- Hot, humid climate (zones 8–11): Culantro is the workhorse for summer; grow cilantro in the cooler shoulder seasons for variety.
- You want coriander seed: Only cilantro produces it, so grow cilantro and let some plants bolt.
- You cook a lot of long-simmered dishes: Culantro’s heat tolerance and intensity make it the better kitchen partner.
- You want fresh garnish and bright salsa: Cilantro’s soft texture is hard to beat raw.
Both herbs reward the same broader gardening habits, steady moisture, healthy soil, and timely harvesting. If you are building out an edible patch, it pairs naturally with other fast leafy crops; see our take on choosing between thyme varieties for another “two similar herbs, different uses” decision, and browse the Plants & Flowers hub for more grow-it-yourself guides.

The Verdict
There is no universal winner, only the right plant for your conditions. Cilantro wins for cool-climate gardeners, raw dishes, and anyone who wants coriander seed, but its short, bolt-prone life means constant resowing. Culantro wins decisively in hot, humid climates and in cooked food, offering months of harvest from a single rugged plant and a far more concentrated flavor. The smartest move for many gardeners is to grow both: cilantro in spring and fall, culantro through the heat of summer, so your “cilantro flavor” never runs out regardless of the thermometer.
Frequently Asked Questions
Do cilantro and culantro taste the same?
They share the same citrusy, sometimes soapy flavor profile, but culantro is roughly three to four times stronger and more pungent. Use about a quarter as much culantro as you would cilantro.
Can I substitute culantro for cilantro in recipes?
Yes, especially in cooked dishes where culantro’s tougher leaves hold up to heat. For raw garnish, cilantro’s soft texture is preferable, but the flavor swap works fine. Cut the quantity way down because culantro is much more intense.
Why does my cilantro keep bolting so fast?
Cilantro bolts when temperatures climb above about 75°F or as days lengthen in early summer. Grow it in the cool spring and fall windows, provide afternoon shade in warm spells, and succession-sow every two to three weeks for a continuous supply.
Is culantro hard to grow from seed?
It germinates slowly and erratically, often two to three weeks, and the seeds need light, so press them onto the soil surface rather than burying them. Keep soil at 75–85°F and consistently moist for the best results.
Can I grow culantro indoors in a cold climate?
Yes. Culantro naturally prefers partial shade, so it adapts well to a bright windowsill or grow light indoors. Bring it inside before frost, as it cannot survive freezing temperatures, and it will keep producing through winter.
