Yes, you can plant catmint and lavender together, and they make fantastic garden companions.
If you’ve been wondering whether you can plant catmint and lavender together, the answer is a resounding yes, because these two perennials thrive under almost identical conditions.
Planting catmint and lavender together is not only possible, but it’s one of the best pairing decisions you can make for a low-maintenance, pollinator-friendly border.
Since both plants hail from the Mediterranean, they share a love for full sun, sharp drainage, and lean soil, which means when you plant catmint and lavender together, they’ll demand the same care without competing for resources.
In this post, we’ll dig into why planting catmint and lavender together works so well, the best spacing and design tips, and how to keep both of these aromatic beauties happy side by side.
Let’s explore the joys of combining these two garden staples.
Why Planting Catmint And Lavender Together Works
The reason you can plant catmint and lavender together so successfully comes down to their shared native habitat and growth habits.
When you plant catmint and lavender together, you’re essentially recreating a sunny, rocky Mediterranean hillside that both species absolutely adore.
Here’s what makes this pairing so harmonious for you and your garden.
1. They Share Identical Sun and Soil Preferences
Both catmint and lavender demand at least six to eight hours of direct sunlight each day.
If you plant catmint and lavender together in a shaded spot, both will stretch, flop over, and produce far fewer blooms.
Soil is where the magic really happens when you plant catmint and lavender together, because both absolutely hate wet feet.
These plants want sandy, gritty, or gravelly soil that drains incredibly fast after a rainstorm.
Heavy clay soil will cause root rot for both, so if you plant catmint and lavender together, always amend the bed with coarse sand or fine gravel before planting.
2. Watering Needs Are Perfectly Matched
Once established, both catmint and lavender are drought-tolerant powerhouses.
When you plant catmint and lavender together, you can water them deeply but infrequently, letting the soil dry out completely between drinks.
Overwatering is the fastest way to kill this pairing, so it’s best to treat them like desert natives.
Because catmint and lavender share such low water requirements, planting catmint and lavender together simplifies your irrigation routine significantly.
3. Visual and Textural Harmony
From a design perspective, these two are a match made in heaven.
Lavender offers upright, silvery-green spikes with purple or blue flower wands that reach toward the sky.
Catmint, on the other hand, forms a soft, mounding fountain of gray-green foliage with delicate, airy blooms in similar shades of violet and periwinkle.
When you plant catmint and lavender together, you get a billowy contrast between lavender’s stiff verticality and catmint’s relaxed sprawl.
This texture play looks stunning along walkways, bordering vegetable beds, or cascading over a sunny retaining wall.
4. A Pollinator Paradise
Both species are nectar factories that bees, butterflies, and hummingbirds absolutely can’t resist.
Planting catmint and lavender together creates an extended, overlapping bloom season that keeps pollinators visiting from late spring through early fall.
Lavender typically flowers first, and as its blooms fade, catmint picks up the slack, so your garden won’t have a dull moment.
Best Ways To Plant Catmint And Lavender Together
Now that you know why these plants are buddies, let’s talk about the practical side of planting catmint and lavender together in your specific yard.
Follow these guidelines for a thriving combination that looks professionally designed.
1. Choose the Right Varieties
Not all lavenders are created equal when it comes to pairing with catmint.
English lavender (Lavandula angustifolia) and French lavender (Lavandula stoechas) both work well when you plant catmint and lavender together.
For catmint, stick with Nepeta faassenii or Nepeta racemosa, which are non-invasive and stay neatly clumped.
Avoid Nepeta mussinii’s wilder cousins, which can self-seed aggressively and overtake your lavender.
2. Mind Your Spacing
Proper airflow is critical when you plant catmint and lavender together.
Lavender should be spaced about 18 to 24 inches apart from its neighbors.
Catmint will spread wider than lavender, so give it a bit more elbow room, roughly 24 to 30 inches.
When you plant catmint and lavender together in the same bed, alternate them in a staggered zigzag pattern rather than straight rows.
This staggered layout allows each plant to receive maximum sun and prevents the more vigorous catmint from smothering the slower-growing lavender.
3. Plant at the Right Time
The best time to plant catmint and lavender together is in the spring after the last frost has passed.
This gives both plants an entire growing season to establish deep root systems before winter arrives.
You can also plant them together in early autumn, as long as you do so at least six weeks before your first hard freeze.
When you plant catmint and lavender together in the fall, root growth continues until the ground freezes, giving them a head start for next spring.
How To Maintain Catmint And Lavender Together
Once you plant catmint and lavender together, maintenance is refreshingly simple.
These are some of the easiest perennials you’ll ever grow, but a few routine tasks will keep them looking pristine.
1. Prune Lavender Lightly in Spring
In early spring, trim lavender back by about one-third, but never cut into the old, woody base.
This encourages fresh, green growth and prevents the plant from becoming leggy.
2. Shear Catmint After Its First Bloom
Catmint will flower heavily in late spring, and then it can look tired and floppy by midsummer.
After the first flush of blooms fades, shear the entire plant back by half.
This hard cutback will encourage a second, vigorous flush of flowers right alongside your lavender’s later bloom.
3. Skip the Fertilizer
This is crucial when you plant catmint and lavender together: do not feed them rich compost or synthetic fertilizer.
These plants actually prefer poor, lean soil, and fertilizing will produce lush foliage at the expense of aromatic oils and flowers.
4. Refresh Mulch With Gravel
While you can plant catmint and lavender together in the ground, using a top dressing of fine gravel or pea stone around the base is beneficial.
This gravel mulch reflects heat upward, keeps the crown dry, and looks incredibly natural.
So, Can You Plant Catmint And Lavender Together?
Yes, you can plant catmint and lavender together, and honestly, you absolutely should.
Planting catmint and lavender together creates a resilient, romantic, and fragrant display that thrives on neglect.
Because they share sun, soil, and water requirements, you’ll spend less time fussing and more time enjoying the lavender-scented breeze.
Planting catmint and lavender together also boosts biodiversity, supports pollinators, and adds months of continuous color to your landscape.
So go ahead, grab a lavender plant and some catmint, prepare a sunny, well-drained spot, and plant catmint and lavender together this season.
Your garden will thank you with waves of purple blooms and a cloud of calming fragrance all summer long.
