Edible Gardening 101: Harvesting Coriander Seeds

By Willi Galloway August 6, 2012 Categories: Edible Gardening 101, Organic Gardening

Cilantro leaves have a flavor that most people either love or hate. But even if you think cilantro tastes like soap, you should still consider growing a few plants in your garden, because cilantro and the spice coriander both come from the same plant, Coriandrum sativum. In the United States most people grow this delicious, multi-purpose herb for its leaves, but its delicious Coriander seeds are entirely worth harvesting and taste nothing like cilantro leaves.

Cilantro is a cool season herb that goes to seed quickly during the long, hot days of summer. The plant’s round, lobed leaves turn feathery as it lengthens up towards the sky. Pretty masses of small white flowers soon appear. These nectar-and-pollen rich blossoms attract tons of pollinators, especially honey bees and syrphid flies. As the blossoms begin to fade, small, round, kelly green coriander seeds appear.

Coriander’s flavor is truly unique—citrusy and slightly nutty, and it pairs very well with beans, lentils, rice, and roasted or grilled vegetables. The seeds can be harvested when they are young and bright green, or you can wait to harvest them until they turn brown.

I like to harvest them at the green stage, because their flavor is sharper and more pronounced, and because the only place you can find green coriander seed is in a garden. I’ve never once spotted them at a grocery store or in a farmers’ market. The seeds keep in the refrigerator for a couple of weeks if stored in a lidded glass container, and they freeze well too.

If you’d like to harvest the mature brown seed, either to plant next year or to grind and use throughout the winter, wait until the majority of the seed turns brown. Then, cut off the seed heads along with a few inches of stalk and hang them upside down in a brown paper bag. When the seeds are fully dry, they will fall out of the heads and into the bottom of the bag. Store the dry seed in a lidded glass jar in a cool, dry location. For the best flavor, grind it right before use. You won’t believe the difference in taste between freshly ground coriander seed and the pre-ground stuff usually available at the supermarket.

Experiment using green coriander seed in marinades and dressings. The flavor of dry, ground coriander works especially well with cumin, so I often add an equal amount of coriander to recipes that call for cumin.

P.S. It also tastes phenomenal when infused in vodka!

I am harvesting the seeds now in Colorado. will let dry some and scatter the rest for next year's crop. altho I don't think it is a perennial from roots (at least at 7800') it reseeds easily after even the coldest of winters. Love to chew the flowers and stems of this plant and it is most definitely an anti-nausea if chewed raw.

Thank you very much for your very informative article about harvesting the seeds. I am a little puzzled because another website advised not to use the seeds for cooking as they had a very unpleasant flavour - you say exactly the opposite! Now I'm confused. But your advice about how to harvest them is excellent.

If I harvest them green, do I crush them before adding them do my marinade or dish?

Do you wash the seeds or just dry them?

Can the seeds be planted during the same season?

Thanks for the informative post. I think I'll wait to use the dried mature seeds.

The cilantro I am growing appears to have pods that have seeds in them. Is this a different variety?

My 1st year growing cilantro and coriander. This has already occurred and I'm wondering how far to cut off the stems for a reproduction of cilantro. Appreciate any ideas in response.
