Grow Your Own Coriander and Cilantro

If you’re from around these parts (this blog, that is), you know that I love cilantro. Even if you don’t care for the taste, cilantro is one of the greatest things to grow in the kitchen garden. It doesn’t take up much space, it brings in beneficial insects, and best of all, it produces something delicious besides the leaves: cilantro seeds. 

And those seeds are also known as coriander.

Cilantro loves to produce seeds. I think I’ve been growing cilantro every year since 2013 or so with seeds I’ve harvested instead of bought. I have a post about how to keep cilantro from bolting because going to seed is all cilantro seems to want to do, but honestly, if it does bolt, you can just plant some more... But now you also have coriander!

Here are the simple steps to save your own coriander.

Step One: Let your cilantro plants go to seed

When cilantro bolts, it produces pretty little white or pale pink flowers (which pollinators love). Those flowers will produce green pods that contain coriander seeds in the making. You could eat these seeds when they’re still green (fresh coriander has a nice little spicy zing), or you can dry them if your goal is to save seeds for next season.

Step Two: Remove your cilantro plant from the garden

Take the entire thing by cutting right at the base of the plant. Leave the roots in the soil so that you don't disturb your other plants. I recommend planting a new round of cilantro so that you'll still be able to enjoy fresh leaves. (Here's a refresher on growing cilantro from seed if you need it!)

Step Three: Hang cilantro to dry

Tie your cilantro stems with twine or wire. Hang them upside down to dry completely out in a spot that's cool, dark, and dry.

Leave them hanging until there’s no more green on the stems. In the picture below, you can see the progression from freshly harvested to not-quite fully dry.

Step Four: Rub the coriander seed pods off the stem

Cilantro seeds are dry when they're light brown and have visible ridges instead of a smooth exterior.

Once the pods are dry, it’s easy to rub them off the stem with your hand (though you could also store the herb stem and all). Rinse the seeds in a kitchen strainer and remove any little extra parts from the pods, trying not to crush the coriander. 

Step Five: Store the coriander seeds

If you’re going to plant the seeds, they need some time to rest first. These are seeds for next year, so use seeds from a seed packet for this month if you're planting a fresh round. I’ll use seeds I saved last summer when I plant more cilantro in the fall once the temps have dropped a bit. 

You can probably harvest at least 500 seeds from three cilantro plants, so... Hope you love coriander seeds on everything!

What Is Coriander Used for?

Coriander seeds have a wonderful spicy citrus flavor. I toss coriander on salads and in stews and sautéed dishes—it’s a great spice to add flavor to a variety of meals. 

You can enjoy coriander seeds fresh, grind them, or toast them, which heightens their flavor. To toast coriander, simply cook the seeds in a dry pan on the oven for a couple of minutes on medium heat before crushing them with a pestle or the flat side of a knife.

If you crush the seeds to make your own coriander seasoning, it's best to enjoy it fresh. Ground coriander loses flavor quickly.

Coriander is a popular spice in garam masala and Indian curries. You might also see coriander used in pickling recipes.

Bonus: Grow Cilantro Microgreens with All Your Cilantro Seeds

If you save seeds from several cilantro plants, you're going to end up with more than you know what to do with. In addition to using some in your kitchen and saving some for next year, try something new and grow your own cilantro microgreens.

Cilantro is one of my favorite varieties of microgreens to grow at home. You can get the same delicious flavor of cilantro but in a fourth of the time it would take to grow a mature plant from seed.

Time to Save Your Own Coriander

I hope this encourages you to harvest your own seeds, my friends, whether to add spice to meals or to become next year's plants! The garden gives us so much, most of it delicious (even if you hate cilantro)!
