How To Harvest Seeds From Lavender

You can harvest seeds from lavender once the flower spikes have fully dried and turned brown on the plant.
 
When you harvest seeds from lavender at the right time, you’ll get viable seeds that you can plant the following season.
 
The process of harvesting seeds from lavender is simple, but timing is everything if you want good results.
 
If you pick the flower heads too early, the seeds inside won’t be mature enough to germinate.
 
In this post, we’ll walk through exactly how to harvest seeds from lavender, when to do it, and how to store them properly.
 
Let’s get started.
 

When to Harvest Seeds from Lavender

Timing is the most important part of harvesting seeds from lavender.
 
If you harvest lavender seeds at the wrong stage, you’ll end up with nothing but chaff.
 
Here’s how to tell when the time is right.
 

1. Wait for the Flowers to Fade and Dry

You should harvest seeds from lavender after the blooms have faded and the flower spikes have turned brown.
 
This usually happens in late summer or early fall, depending on your climate.
 
The petals will drop, and the calyxes along the spike will look dry and papery.
 
That’s your signal that the seeds inside are mature and ready.
 

2. Watch for the Seeds to Darken

If you look closely at the dried flower heads, you’ll notice tiny seeds forming.
 
Healthy lavender seeds are dark brown to black and slightly oval.
 
When you’re harvesting seeds from lavender, you want to wait until those seeds are fully dark before you cut anything.
 
Green or pale seeds usually won’t germinate.
 

3. Check the Weather Before You Cut

Pick a dry, sunny day to harvest lavender seeds.
 
Moisture is the enemy here because damp seed heads can mold quickly.
 
If rain is in the forecast, wait a few days.
 
The drier the plant is when you harvest seeds from lavender, the better your results will be.
 

How to Harvest Seeds from Lavender Step by Step

Once your lavender is ready, harvesting seeds from lavender takes just a few minutes.
 
Here’s the process from start to finish.
 

1. Gather Your Materials

Before you start harvesting seeds from lavender, grab a few supplies.
 
You’ll need sharp scissors or pruning shears, a paper bag or a small bowl, and a labeled envelope or jar for storage.
 
Paper works better than plastic because it lets any leftover moisture escape.
 

2. Snip the Dried Flower Spikes

Cut the dried flower spikes off the plant, leaving a few inches of stem attached.
 
When you harvest seeds from lavender, cut just above a set of leaves so the plant stays healthy.
 
You can cut several spikes at once and drop them straight into your bag or bowl.
 

3. Let the Seed Heads Dry Further

If the flower spikes still feel slightly soft, spread them out in a single layer in a dry, warm spot for a few days.
 
This extra drying step makes harvesting seeds from lavender much easier.
 
The seeds will loosen up inside the dried calyxes.
 

4. Rub the Flower Heads to Release the Seeds

Take a dried flower spike and rub it between your fingers over your bowl or bag.
 
You’ll see small dark seeds fall out along with some chaff.
 
Keep rubbing until you’ve harvested seeds from lavender from all your spikes.
 

5. Separate the Seeds from the Chaff

Pick out the larger pieces of dried plant material by hand.
 
Then gently shake the bowl so the lighter chaff rises to the top, or use a fine sieve.
 
Clean seeds store better and are easier to plant later.
 

How to Store Lavender Seeds After Harvesting

After harvesting seeds from lavender, proper storage keeps them viable for years.
 
Follow these simple steps to protect your harvest.
 

1. Use a Paper Envelope or Glass Jar

Place your dried seeds in a paper envelope or a small glass jar with a tight lid.
 
Paper is great for short-term storage because it breathes.
 
Glass jars work well for longer storage as long as the seeds are completely dry.
 

2. Label Everything

Write the date and the lavender variety on your container.
 
When you harvest seeds from lavender, you might forget which plant they came from by spring.
 
A quick label saves you a lot of guessing later.
 

3. Keep Them Cool and Dark

Store your seeds in a cool, dark, dry place like a cupboard or pantry.
 
Avoid humid spots like basements or bathrooms.
 
Stored this way, seeds from lavender can stay viable for two to three years.
 

4. Consider Cold Stratification Before Planting

Lavender seeds germinate better after a cold period.
 
About four to six weeks before your last frost date, pop your seeds in the fridge.
 
This mimics winter and boosts your success rate when you plant the seeds you harvested from lavender.
 

So, How Do You Harvest Seeds from Lavender?

You harvest seeds from lavender by waiting until the flower spikes turn brown and dry, then snipping them off and rubbing the seed heads to release the seeds.
 
Timing matters more than anything else, so don’t rush the process.
 
Once you’ve harvested seeds from lavender, store them in a cool, dark spot and give them a cold period before planting.
 
With a little patience, you’ll have free lavender seeds ready to grow next season.
