How To Grow Lavender In Missouri

You can grow lavender in Missouri successfully if you choose the right varieties and give them the sunny, well-drained conditions they crave.
 
Missouri sits right in the middle of the country with hot, humid summers and cold, wet winters, which can be tough on lavender.
 
But with a little planning, growing lavender in Missouri is absolutely doable, even in our unpredictable climate.
 
The key is picking the right type of lavender and preparing your soil so it never stays soggy.
 
In this post, we’ll walk through how to grow lavender in Missouri, from choosing varieties to planting, caring, and overwintering your plants.
 
Let’s dig in.
 

Why Growing Lavender in Missouri Takes a Bit of Strategy

Growing lavender in Missouri is possible, but it’s not as simple as sticking it in the ground and walking away.
 
Missouri’s climate presents a few challenges that lavender growers need to work around.
 
Here’s what you’re up against.
 

1. Humidity Is the Enemy

Lavender originates from the dry, rocky hills of the Mediterranean.
 
It loves hot, dry air and hates muggy conditions.
 
Missouri summers are famously humid, and that moisture in the air can lead to root rot and fungal diseases like powdery mildew.
 
That’s why growing lavender in Missouri means focusing on airflow and drainage above all else.
 

2. Wet Winters Can Be Deadly

Lavender is hardy, but it doesn’t like sitting in wet, freezing soil.
 
Missouri winters often bring rain, snow, and freeze-thaw cycles that turn clay soil into a soggy mess.
 
If your lavender’s roots stay wet through winter, the plant will likely rot before spring arrives.
 

3. Clay Soil Needs Amending

Much of Missouri has heavy clay soil that holds water like a sponge.
 
Lavender needs soil that drains fast and dries out quickly.
 
So if you’re growing lavender in Missouri, you’ll almost certainly need to amend your soil or plant in raised beds.
 

Best Lavender Varieties to Grow in Missouri

Choosing the right variety is half the battle when growing lavender in Missouri.
 
Here are the types that handle our climate best.
 

1. English Lavender (Lavandula angustifolia)

English lavender is the most cold-hardy option and handles Missouri winters well.
 
Look for varieties like ‘Munstead’ and ‘Hidcote’ which are compact, fragrant, and reliable.
 
These bloom in early summer and can sometimes give you a second flush in fall.
 

2. ‘Phenomenal’ Lavender

This hybrid is a rockstar for growing lavender in Missouri.
 
It’s incredibly tough, tolerates humidity better than most, and survives both cold winters and hot summers.
 
If you only plant one lavender, make it this one.
 

3. Spanish and French Lavender

These are less hardy and really struggle with Missouri winters.
 
You can grow them in pots and bring them indoors, but they’re not ideal for permanent garden beds here.
 
Stick with English and hybrid varieties for the best results.
 

How to Plant Lavender in Missouri

Getting planting right sets your lavender up for success.
 
Here’s how to do it.
 

1. Pick the Sunniest Spot You Have

Lavender needs at least six to eight hours of full sun every day.
 
The more sun, the better, especially in Missouri where humidity lingers.
 
South-facing slopes or raised beds are ideal.
 

2. Amend Your Soil for Drainage

Mix in plenty of coarse sand, pea gravel, or horticultural grit to improve drainage.
 
If you’re dealing with heavy clay, raised beds are your best friend.
 
Aim for soil that drains within 30 minutes after a heavy rain.
 

3. Plant in Spring After Frost

Wait until the danger of frost has passed in your area.
 
Space plants 12 to 18 inches apart to allow good airflow.
 
This spacing helps prevent fungal issues during humid Missouri summers.
 

Caring for Lavender in Missouri

Once your lavender is in the ground, a little maintenance goes a long way.
 

1. Water Deeply but Infrequently

Water your lavender deeply once every week or two during dry spells.
 
Let the soil dry out completely between waterings.
 
Overwatering is the number one killer of lavender in Missouri.
 

2. Prune After Blooming

Trim back about one-third of the plant after it finishes blooming.
 
Don’t cut into the woody stems, just the soft green growth.
 
Pruning keeps the plant bushy and prevents it from getting leggy.
 

3. Skip the Mulch Around the Base

Mulch holds moisture, which lavender hates.
 
Instead, use gravel or sand as a top dressing to keep the crown dry.
 
This is especially important during Missouri’s humid months.
 

4. Overwinter with Care

In Missouri, winter protection matters.
 
Avoid covering lavender with heavy mulch, which traps moisture.
 
Instead, ensure good drainage and consider planting on a slope or in raised beds so water never pools around the roots.
 

So, Can You Grow Lavender in Missouri?

You can grow lavender in Missouri if you choose hardy varieties and give them fast-draining soil and plenty of sun.
 
Yes, Missouri’s humidity and wet winters make growing lavender in Missouri a bit tricky, but it’s far from impossible.
 
Stick with English or hybrid varieties, plant in raised beds if your soil is heavy clay, and water sparingly.
 
With these tips, growing lavender in Missouri can reward you with fragrant blooms year after year.
