Can You Plant Catmint and Lavender Together

Catmint and lavender make excellent garden companions because they both thrive in full sun, well-draining soil, and require minimal watering once established. Planting them together creates a stunning visual display with complementary purple-blue blooms and attracts beneficial pollinators while naturally deterring many garden pests.

If you’ve ever wandered through a sunny garden in early summer and caught that incredible blend of minty, floral fragrance drifting on the breeze, chances are you’ve experienced the magic of catmint and lavender growing side by side. These two Mediterranean herbs have become darlings of the gardening world, and for good reason. They’re beautiful, they’re tough, and they smell absolutely divine. But the question on many gardeners’ minds is simple: can you plant catmint and lavender together?

The short answer is a resounding yes. In fact, these two plants might just be the perfect garden partners. They’re like old friends who bring out the best in each other – similar needs, complementary bloom times, and a combined fragrance that turns any garden path into a sensory experience. But like any good partnership, there are a few things to know to make this relationship thrive. Let’s dig into everything you need to know about growing catmint and lavender together.

Quick Answers to Common Questions

Can catmint and lavender be planted in the same hole?

No, plant them in separate holes spaced 18-24 inches apart. Each plant needs its own root zone and air circulation. Planting in the same hole leads to competition and poor air flow, increasing disease risk.

Which blooms first, catmint or lavender?

Catmint typically blooms first, starting in late spring (May in many zones). Lavender follows in early to mid-summer (June-July). This staggered bloom creates months of continuous flowers.

Do catmint and lavender have the same water needs?

Yes, both are drought-tolerant once established and prefer dry conditions. Water new plantings regularly the first season, then rarely if ever. Overwatering is the most common cause of failure for both.

Will catmint choke out lavender?

Not if spaced properly (24 inches apart). Catmint is clump-forming, not aggressive. However, floppy catmint stems can smother nearby lavender after heavy rain. Shear catmint after first bloom to keep it upright.

Can I grow catmint and lavender in part shade?

Both need full sun (6+ hours) for best growth, flowering, and disease resistance. In hot southern zones, they tolerate light afternoon shade. In shade, they become leggy, flower poorly, and are prone to powdery mildew and rot.

Why Catmint and Lavender Make Perfect Companions

Shared Mediterranean Heritage

Both catmint (Nepeta) and lavender (Lavandula) hail from the Mediterranean region, which means they’ve evolved to handle the same challenging conditions. Hot, dry summers? Check. Poor, rocky soil? Check. Intense sunlight? Double check. When you plant them together, you’re essentially recreating a little slice of their native habitat. This shared heritage is the foundation of their compatibility – they speak the same language when it comes to growing conditions.

Think about it this way. If you try to pair a water-loving plant like astilbe with lavender, one of them is going to be unhappy. The astilbe will wither in the dry conditions lavender loves, or the lavender will rot in the moisture astilbe needs. But catmint and lavender? They’re on the exact same page. They both shrug off drought, laugh at poor soil, and bask in full sun. This means you can water them on the same schedule, amend the soil the same way, and site them in the same sunny spot without compromise.

Complementary Bloom Times

One of the most delightful aspects of this pairing is how their flowering seasons dance together. Catmint typically kicks off the show in late spring, often blooming as early as May in many regions. It produces waves of small, tubular flowers in shades of lavender-blue, purple, or sometimes white, depending on the variety. The bloom continues heavily through early summer, then often takes a brief pause during the hottest weeks before pushing out a second flush in late summer to fall.

Lavender, on the other hand, usually hits its stride in early to mid-summer, just as catmint’s first big flush is winding down. English lavender (Lavandula angustifolia) typically blooms June through July, while French and Spanish lavenders can bloom even earlier and longer. This staggered timing means you get months of continuous color – catmint carries the early season, lavender takes center stage in mid-summer, and catmint often returns for an encore in fall. It’s like having a relay race where the baton pass is seamless.

Pollinator Paradise

If you love watching bees, butterflies, and hummingbirds in your garden, this duo is a powerhouse. Both plants are absolutely magnetic to pollinators. Catmint’s nectar-rich flowers attract a dizzying array of native bees, honeybees, bumblebees, and butterflies. I’ve stood next to a mature ‘Walker’s Low’ catmint on a sunny July morning and counted dozens of bees working the flowers at once. It’s a hive of activity.

Lavender is equally beloved, particularly by bumblebees and honeybees. The combination means your garden becomes a pollinator buffet from late spring through early fall. This isn’t just pretty – it’s practical. More pollinators mean better fruit set on your vegetable crops, healthier ecosystem balance, and the simple joy of a garden buzzing with life. Plus, both plants are deer and rabbit resistant thanks to their strong essential oils, so your pollinator buffet won’t become a mammal salad bar.

Understanding Each Plant’s Personality

Getting to Know Catmint

Before we dive deeper into the partnership, let’s appreciate each plant individually. Catmint (Nepeta) isn’t just one plant – it’s a genus with several garden-worthy species and countless cultivars. The most common garden catmint is Nepeta x faassenii, a hybrid that includes popular varieties like ‘Walker’s Low’ (Perennial Plant of the Year in 2007), ‘Cat’s Meow’, ‘Cat’s Pajamas’, and ‘Junior Walker’. There’s also Nepeta racemosa (sometimes sold as N. mussinii), which tends to be lower and more spreading, and Nepeta subsessilis, which tolerates a bit more moisture and shade than its cousins.

Catmint forms mounds of aromatic, gray-green foliage topped with spikes of small flowers. The leaves release a minty fragrance when brushed or crushed – hence the name. And yes, cats do love it, though usually not as intensely as true catnip (Nepeta cataria). Most garden catmints are sterile hybrids, meaning they won’t self-seed aggressively like catnip can. They’re hardy in USDA zones 3-8, sometimes 9, making them incredibly versatile across North America.

Size varies by variety. ‘Walker’s Low’ (ironically not low at all) reaches 24-30 inches tall and wide. ‘Junior Walker’ and ‘Cat’s Pajamas’ are more compact at 12-18 inches. ‘Cat’s Meow’ sits in the middle around 18-24 inches. This range means there’s a catmint for almost any spot – front of border, middle ground, or even containers.

Getting to Know Lavender

Lavender brings its own cast of characters. English lavender (Lavandula angustifolia) is the classic, most cold-hardy type (zones 5-9), with varieties like ‘Hidcote’, ‘Munstead’, ‘Royal Velvet’, and ‘Melissa Lilac’. It forms neat, compact mounds 12-24 inches tall with those iconic narrow, silvery-gray leaves and dense flower spikes.

French lavender (Lavandula dentata) and Spanish lavender (Lavandula stoechas) are less cold-hardy (zones 7-9 and 8-9 respectively) but bloom longer and have those distinctive “rabbit ear” bracts atop the flower heads. Then there are the lavandins (Lavandula x intermedia) – hybrids like ‘Grosso’, ‘Provence’, and ‘Phenomenal’ – which are larger, more vigorous, and incredibly fragrant, often used for commercial oil production. They’re hardy to zone 5 or 6.

All lavenders share that unmistakable fragrance – floral, herbaceous, slightly sweet, with camphoraceous notes. The foliage is evergreen in mild winters, providing year-round structure. But here’s the critical thing: lavender hates wet feet. More lavender plants die from winter wet than winter cold. This is where catmint’s similar drainage needs become so valuable.

Creating the Perfect Growing Environment

Sun Requirements – Non-Negotiable

Let’s start with the absolute essential: both plants need full sun. We’re talking 6-8 hours of direct, unfiltered sunlight minimum. Eight hours is even better. In hot southern climates, they can tolerate a tiny bit of afternoon shade, but in northern gardens, full sun all day is ideal. Without enough sun, both plants become leggy, floppy, and flower poorly. They also become more susceptible to fungal diseases.

If your garden has a spot that bakes in the afternoon sun – the kind where other plants crisp up – that’s the sweet spot for this duo. They thrive in heat. A south-facing slope, a west-facing wall, or an open sunny bed are all perfect. The reflected heat from hardscaping like stone walls or pavers? They love it. This makes them ideal for those tough “hell strip” areas between sidewalk and street, or along a driveway where heat radiates.

Soil – The Drainage Imperative

If sun is requirement number one, drainage is requirement number one-A. Both catmint and lavender evolved in lean, gritty, alkaline soils. They despise heavy clay that stays soggy. If you have clay soil (and many of us do), you have two options: amend heavily or build up.

For amending, work in coarse sand, fine gravel, or expanded shale along with some compost. Aim for a 50/50 mix of native soil and amendment in the planting hole, but don’t just amend the hole – that creates a “bathtub effect” where water collects. Amend a wider area. Better yet, create raised beds or berms. Mounding the soil 6-12 inches above grade dramatically improves drainage. This is especially crucial for lavender, which can rot in a single wet winter if drainage isn’t sharp.

Soil fertility? Keep it lean. Rich, heavily fertilized soil produces lush, floppy growth with fewer flowers and less essential oil (meaning less fragrance). These plants thrive on neglect. A light top-dressing of compost in spring is plenty. Skip the fertilizer entirely. If your soil is very acidic (below 6.5), add some lime to bring it closer to neutral or slightly alkaline. Lavender especially prefers pH 6.5-7.5.

Watering – Less Is More

Here’s where many well-meaning gardeners go wrong: overwatering. Both plants are drought-tolerant once established, but “once established” is the key phrase. New plantings need regular water for their first growing season – about an inch per week if rain doesn’t provide it. Water deeply but infrequently to encourage deep roots. Daily light sprinklings create shallow roots and weak plants.

After year one? You can pretty much ignore them unless you’re in an extreme drought. In fact, established lavender often performs better with zero supplemental water. Catmint is a bit more tolerant of occasional moisture but still prefers dry. The biggest mistake is planting them near thirsty plants like roses, hydrangeas, or vegetables that need regular irrigation. Keep the watering zones separate.

A great trick: plant them near your hose bib or at the far end of the garden where the hose doesn’t reach. Out of sight, out of mind – which is exactly how they like it.

Designing With Catmint and Lavender

Spacing for Success

Proper spacing is where the rubber meets the road for this combination. Both plants need good air circulation to prevent fungal issues like powdery mildew (catmint) or root rot (lavender). Crowding them creates a humid microclimate that invites trouble.

For most catmint varieties, space plants 18-24 inches apart on center. For lavender, 18-24 inches for English types, 24-36 inches for larger lavandins. When interplanting, split the difference – aim for 24 inches between each plant, whether it’s catmint-to-catmint, lavender-to-lavender, or catmint-to-lavender. This gives each plant room to reach its natural mature width without touching its neighbors.

If you’re creating a drift or mass planting, stagger them in a triangle pattern rather than straight rows. This looks more natural and maximizes air flow. For a border edge, you might plant a single row alternating catmint and lavender, spaced 24 inches apart. The effect is a rhythmic, flowing line of silver-green foliage and purple-blue blooms.

Height Graduation and Layering

Consider the mature heights when placing them in your bed. Taller catmints like ‘Walker’s Low’ (30 inches) work well in the middle of a border, with shorter lavenders like ‘Hidcote’ (18 inches) in front. Or use compact catmints like ‘Junior Walker’ (14 inches) at the front edge with taller lavandins like ‘Grosso’ (36 inches) behind. The key is creating a gentle stair-step so everything gets sun and nothing gets shaded out.

Remember that catmint tends to be a bit looser and more billowy in habit, while lavender is typically tighter and more structured. This contrast is beautiful – the soft clouds of catmint against the neat mounds of lavender. But if catmint flops (which it can after heavy rain or in rich soil), it can smother nearby lavender. A quick shear after the first bloom keeps catmint tidy and upright.

Color Harmony and Contrast

The classic combination is purple-blue catmint with purple lavender – a monochromatic scheme that’s sophisticated and soothing. But don’t feel locked in. White-flowered catmint (‘White Wonder’, ‘Snowflake’) paired with deep purple ‘Hidcote’ lavender creates striking contrast. Pink catmint (‘Pink Cat’, ‘Dawn to Dusk’) with white lavender (‘Nana Alba’, ‘Crystal Lights’) is soft and romantic.

Foliage color plays a role too. Catmint’s gray-green leaves next to lavender’s silvery-gray creates subtle tonal variation. In winter, when catmint dies back (in cold climates) or goes semi-dormant, lavender’s evergreen structure carries the show. In milder zones where catmint stays evergreen, you get year-round silver-green texture.

Companion Planting Beyond the Duo

While catmint and lavender are stars together, they also play well with others. Consider adding these companions for an extended season and layered look:

• Spring bulbs: Plant daffodils, alliums, or species tulips between them. The bulbs bloom before the perennials fill in, and the emerging foliage hides dying bulb leaves.
• Ornamental grasses: Blue fescue (Festuca glauca), Mexican feather grass (Stipa tenuissima), or little bluestem (Schizachyrium scoparium) add movement and winter interest.
• Other Mediterranean herbs: Rosemary, thyme, sage, and oregano share the same growing conditions and create a true herb garden vibe.
• Drought-tolerant perennials: Salvia, Russian sage (Perovskia), yarrow (Achillea), sedum, and coneflower (Echinacea) all thrive in the same conditions.
• Roses: Shrub roses love the same sun and drainage. Catmint and lavender at their feet hide bare canes and deter pests.

Maintenance Made Simple

Pruning Catmint – The Chelsea Chop and Beyond

Catmint benefits from a few strategic haircuts. The first is optional but transformative: the “Chelsea Chop” in late May or early June (around the time of the Chelsea Flower Show in England). Cut the plant back by one-third to one-half before it blooms. This delays flowering by a few weeks, creates a bushier, more compact plant that won’t flop, and often increases total flower production. It’s especially useful for taller varieties like ‘Walker’s Low’.

After the first major flush fades (usually July), shear the whole plant back by about half. This removes spent flowers, tidies the foliage, and stimulates that gorgeous second bloom in late summer. Use hedge shears or large scissors – it’s a quick job. In late fall or early spring, cut dead foliage to the ground. In mild winters where it stays evergreen, just trim out any winter-damaged bits in spring.

Pruning Lavender – The Golden Rules

Lavender pruning strikes fear into many gardeners, but it’s straightforward if you follow two rules: never cut into old wood, and prune annually. Old wood (the thick, brown, woody stems at the base) rarely resprouts. If you cut there, you leave a permanent hole. Always leave 2-3 inches of green growth above the woody base.

Prune in spring after new growth appears (usually April-May). Shape the plant into a neat mound, removing about one-third of the green growth. This prevents the center from opening up and getting woody. After flowering, you can do a light trim to remove spent flower stalks and shape slightly, but the main prune is spring. In zone 5 and colder, wait until you see clear new growth – pruning too early can stimulate tender growth that gets zapped by a late freeze.

Dividing and Refreshing

Catmint benefits from division every 3-4 years in spring. The center can become woody and die out, leaving a donut shape. Dig the whole clump, discard the woody center, and replant the vigorous outer sections. Water well until established. This rejuvenates the plant and gives you free plants to share or spread around.

Lavender generally doesn’t need division and resents root disturbance. If a plant becomes woody and unsightly after 5-10 years, it’s often best to replace it. You can propagate new plants from semi-hardwood cuttings in summer – easy and reliable. Take 3-4 inch cuttings, strip lower leaves, dip in rooting hormone, and stick in gritty potting mix. Keep humid until rooted.

Fertilizing – Just Say No

I cannot emphasize this enough: do not fertilize these plants. Not with synthetic fertilizer, not with manure, not with rich compost. They evolved in poor soil. Fertilizer produces weak, floppy, disease-prone growth with diluted essential oils. If your soil is truly terrible (pure sand or subsoil), a light sprinkle of compost at planting time is fine. After that, hands off. The best fertilizer for these plants is neglect.

Troubleshooting Common Issues

Catmint Flopping Open

This is the number one catmint complaint. The plant looks great in spring, then after heavy rain or in rich soil, the stems splay outward, leaving a bare center. Solutions: Chelsea Chop in late spring, proper spacing for air flow, lean soil, and shearing hard after first bloom. Staking works but looks fussy. Better to prevent with good culture.

Lavender Dying in Winter

Usually it’s not the cold – it’s wet soil. Lavender roots rot in cold, wet conditions. Solutions: sharp drainage (berms, raised beds, gravel mulch), planting high (crown slightly above soil level), avoiding organic mulch right against the crown (use gravel or nothing), and choosing hardy varieties for your zone. ‘Phenomenal’ and ‘Hidcote’ are notably tough.

Powdery Mildew on Catmint

Appears as white dusty coating on leaves, usually in humid summers with poor air flow. Solutions: proper spacing, morning sun to dry foliage, avoid overhead watering, and shear affected foliage (it regrows clean). Some varieties are more resistant – ‘Cat’s Meow’ and ‘Cat’s Pajamas’ show good resistance.

Woody, Leggy Lavender

Old lavender gets woody at the base with all growth at the tips. Annual spring pruning prevents this. Once it’s severely woody, it’s hard to renovate. You can try cutting back hard in spring to just above the lowest green shoots, but success is iffy. Better to start new plants from cuttings and replace.

Catmint Taking Over

Most garden catmints are clump-forming, not runners. But they can self-seed modestly. Deadhead after flowering if you want to prevent seedlings. ‘Walker’s Low’ rarely seeds. Nepeta racemosa types seed more readily. Seedlings are easy to pull or transplant.

Seasonal Care Calendar

Spring (March-May)

• Cut back catmint to ground (cold climates) or remove winter damage (mild climates)
• Prune lavender when new growth appears – shape into mound, remove 1/3 green growth
• Apply light compost top-dressing if desired (skip if soil is decent)
• Plant new additions after last frost
• Chelsea Chop catmint late May (optional)

Summer (June-August)

• Enjoy first catmint bloom (usually starts May/June)
• Enjoy lavender bloom (usually June/July)
• Shear catmint back by half after first flush fades (July)
• Light trim lavender after bloom to remove spent stalks
• Water new plantings deeply weekly if dry; established plants rarely need water
• Take lavender cuttings for propagation (July)

Fall (September-November)

• Enjoy catmint second flush (often September-October)
• Stop all pruning 6 weeks before first frost – let plants harden off
• Plant new lavender in early fall (zones 6+) for root establishment before winter
• Divide catmint if needed (early fall)
• Apply gravel mulch around lavender crowns for winter protection (cold zones)

Winter (December-February)

• Leave plants standing – foliage protects crowns
• Brush heavy snow off lavender to prevent breakage
• Plan next year’s additions
• Order bare-root or plug plants for spring

Container Growing – Yes, You Can!

Don’t have the perfect garden spot? Both plants thrive in containers, which actually solves the drainage issue beautifully. Choose pots at least 16-18 inches wide and deep. Terra cotta is ideal – it breathes and wicks moisture. Use a gritty mix: 2 parts quality potting soil, 1 part coarse sand or perlite, 1 part fine gravel or chicken grit. Add a tablespoon of garden lime per gallon of mix.

Plant one lavender or one catmint per pot, or combine in a large trough (24+ inches) with 12-inch spacing. Water when the top 2 inches of soil are dry. Fertilize once in spring with half-strength balanced fertilizer – that’s it. Overwinter in zone 5 and colder by moving pots to an unheated garage or burying them in mulch. In zones 6+, they can often stay out with some protection.

Container growing lets you move them to follow the sun, bring fragrance to a patio, or create a portable herb garden. Plus, you get to appreciate the foliage texture and fragrance up close.

Harvesting and Using Your Bounty

One of the joys of this pairing is the harvest. Both plants offer more than just garden beauty.

Lavender Harvest

Cut lavender stems when the bottom few flowers on the spike have opened but the top is still in bud. This is peak oil content. Cut in the morning after dew dries but before heat of day. Bundle 50-100 stems with rubber bands (they shrink as stems dry) and hang upside down in a dark, dry, well-ventilated space. In 2-3 weeks, they’re dry. Strip buds for sachets, potpourri, culinary use (English lavender only), or infuse in oil for salves and lotions.

Catmint Harvest

Catmint leaves and flowers can be harvested anytime for tea. It makes a pleasant, mildly minty, relaxing herbal tea – great before bed. Cut stems, strip leaves and flowers, dry on screens or hang small bundles. For cat toys, harvest just as flowers open – that’s peak nepetalactone (the compound cats love). Dry and stuff into fabric toys. Your cats will thank you.

Culinary Notes

English lavender (L. angustifolia) is the only lavender recommended for cooking – others have high camphor content that tastes soapy. Use sparingly in shortbread, honey, lemonade, or herbes de Provence blends. Catmint tea is safe for most people but avoid during pregnancy (can stimulate uterus) and if you’re on sedatives (may enhance effect). As with any herb, moderation and knowledge are key.

Conclusion

So, can you plant catmint and lavender together? Absolutely, unequivocally, enthusiastically yes. These two Mediterranean natives are a match made in garden heaven. They share the same tough, sun-loving, drought-tolerant DNA. They bloom in a gorgeous relay that keeps the color coming for months. They perfume the air with a fragrance blend that’s better than any candle. They feed the bees, deter the deer, and ask for so little in return.

The secret to success is simple: give them sun, give them drainage, give them space, and then leave them alone. Resist the urge to water, fertilize, or fuss. These are plants that thrive on benign neglect. Plant them along a sunny path where you’ll brush past and release their fragrance. Plant them in a border where their silver-green foliage creates a cooling backdrop for hot-colored flowers. Plant them in pots on your patio where you can snip a stem for tea or a sachet.

However you use them, catmint and lavender together create a garden that’s beautiful, resilient, alive with pollinators, and deeply satisfying. It’s a partnership that reminds us why we garden in the first place – for those perfect moments when beauty, fragrance, and ecology align. So go ahead, plant them together. Your garden (and your nose) will thank you.

Frequently Asked Questions

How far apart should I plant catmint and lavender?

Space plants 18-24 inches apart on center, whether planting catmint next to catmint, lavender next to lavender, or the two together. This spacing ensures good air circulation, reduces disease risk, and allows each plant to reach its natural mature width without crowding.

What is the best time of year to plant catmint and lavender?

Spring after the last frost is ideal for both, giving them a full season to establish roots before winter. In zones 6 and warmer, early fall planting (September-October) also works well for lavender, as roots establish in cool soil before winter. Avoid summer planting in hot climates.

Do I need to deadhead catmint and lavender?

For catmint, shearing the entire plant back by half after the first bloom flush (usually July) is better than individual deadheading – it stimulates a second bloom and keeps the plant tidy. For lavender, remove spent flower stalks after blooming by cutting just below the foliage mound, which maintains shape and prevents woody centers.

Why is my lavender dying while my catmint thrives?

Lavender is more sensitive to wet soil and winter moisture than catmint. Common causes: poor drainage (clay soil without amendment), organic mulch against the crown holding moisture, overwatering, planting too deep, or a variety not hardy in your zone. Catmint tolerates slightly heavier soil and more moisture.

Can I grow catmint and lavender in clay soil?

Yes, but you must amend heavily or create raised beds/berms. Mix coarse sand, fine gravel, or expanded shale 50/50 with native clay over a wide area, not just the planting hole. Plant high with the crown slightly above soil level. Mulch with gravel, not wood chips. Sharp drainage is non-negotiable for lavender especially.

Are catmint and lavender deer resistant?

Yes, both are highly deer and rabbit resistant due to their strong essential oils and aromatic foliage. Deer rarely browse them unless desperate. This makes the duo excellent for unfenced gardens in deer-prone areas. However, no plant is 100% deer-proof in all situations.
