How To Collect Seeds From Cilantro Plant

You can collect seeds from a cilantro plant by letting the plant bolt, flower, and then produce coriander seeds.
 
This is actually one of the easiest seed-saving projects you can do in your garden.
 
Cilantro is a cool-season herb that naturally goes to seed quickly, especially as the weather warms up.
 
Those little green balls that show up after the flowers fade are the seeds you’re after.
 
In this post, we’ll walk through exactly how to collect seeds from a cilantro plant so you can save them for next season or use them in the kitchen.
 
Let’s dig in.
 

Why You Should Collect Seeds From a Cilantro Plant

Learning how to collect seeds from cilantro is worth the effort for a few good reasons.
 

1. Free Seeds for Next Season

When you collect seeds from a cilantro plant, you save money on buying new packets every spring.
 
One healthy cilantro plant can produce dozens of seeds, which means you’ll have plenty to plant again.
 

2. You Get Coriander Too

The seeds of the cilantro plant are actually coriander, a popular spice used in curries, soups, and stews.
 
So when you collect seeds from cilantro, you’re harvesting two things at once: next year’s plants and this year’s seasoning.
 

3. It’s Ridiculously Easy

Collecting seeds from a cilantro plant takes almost no skill.
 
You basically let the plant do its thing, then grab the seeds when they’re ready.
 
That’s it.
 

How to Collect Seeds From a Cilantro Plant Step by Step

Here’s the simple process for how to collect seeds from cilantro, from flower to harvest.
 

1. Let Your Cilantro Bolt

The first step in collecting seeds from a cilantro plant is letting it bolt.
 
Bolting means the plant sends up a tall stalk and starts producing flowers instead of leaves.
 
This happens naturally when temperatures rise, so don’t fight it if you want seeds.
 

2. Wait for the Flowers to Fade

Once your cilantro plant flowers, small white or pink blooms will appear.
 
After those flowers fade, tiny green seeds start to form.
 
This is the beginning of the seed-collecting stage, so keep an eye on them.
 

3. Watch for the Seeds to Turn Brown

The seeds of the cilantro plant start green and slowly turn tan or light brown as they mature.
 
When you see most of the seeds on the stalk turn brown, that’s your cue to get ready.
 
If you collect seeds from cilantro too early, they won’t be viable for planting.
 

4. Snip the Seed Heads

Once the seeds are brown, grab a pair of scissors or pruners and snip off the seed heads.
 
You can cut the whole stalk or just the clusters of seeds.
 
When you collect seeds from a cilantro plant at this stage, you’re getting them at peak readiness.
 

5. Let Them Dry Fully

After you collect seeds from cilantro, spread them out on a paper towel or screen to dry.
 
Leave them in a cool, dry spot for about a week.
 
This step matters because any moisture left in the seeds can cause mold during storage.
 

6. Separate the Seeds From the Chaff

Once dry, gently rub the seed heads between your fingers.
 
The seeds will fall away from the dried stems and husks.
 
Now you have clean seeds ready for storage when you collect seeds from a cilantro plant.
 

Tips for Collecting Seeds From a Cilantro Plant

These little pointers will help you get the best results when you collect seeds from cilantro.
 

1. Timing Is Everything

The best time to collect seeds from a cilantro plant is when the seeds are brown but before they drop.
 
If you wait too long, the seeds will scatter on their own, and you’ll lose them.
 

2. Use a Bag to Catch Falling Seeds

A clever trick is to tie a small paper bag over the seed head as it ripens.
 
That way, when you collect seeds from cilantro, any that fall land right in the bag.
 

3. Store Them Properly

Once you collect seeds from cilantro, store them in a paper envelope or a glass jar.
 
Keep them in a cool, dark, dry place, and they’ll stay viable for a couple of years.
 
Label the container with the date so you know how fresh they are.
 

4. Plant Them or Eat Them

You can plant the seeds you collect from a cilantro plant next season, or crush them and use them as coriander in your cooking.
 
Either way, you’re getting real value from a plant that’s already done its job.
 

5. Don’t Wash the Seeds

Resist the urge to rinse the seeds after you collect seeds from cilantro.
 
Water can kickstart mold, and dry seeds store far better.
 
Just brush off any loose dirt and you’re good.
 

So, How Do You Collect Seeds From a Cilantro Plant?

You collect seeds from a cilantro plant by letting it bolt, flower, and produce brown seeds, then snipping the seed heads and drying them fully.
 
It’s a simple process that rewards you with free seeds and a stash of coriander for your kitchen.
 
The key is patience and timing: wait until the seeds turn brown, then harvest before they drop.
 
Once you know how to collect seeds from cilantro, you’ll never need to buy them again.
 
So let that cilantro go to seed this season and enjoy the harvest.
