Quick Answers to Common Questions

What is the difference between catmint and catnip?

Catnip (Nepeta cataria) is a specific species grown for its strong effect on cats, while catmint refers to ornamental Nepeta hybrids like Nepeta x faassenii that are bred for garden performance with longer bloom times and better form.

How do I keep catmint blooming all summer?

Shear the plant back by one-third to one-half after each major flush of flowers fades. This deadheading stimulates fresh growth and new flower buds, giving you two to three bloom cycles per season.

Will catmint survive winter in cold climates?

Yes, most catmint varieties are hardy in USDA zones 3-8. The top growth dies back, but the crown survives underground. Mulch lightly after the ground freezes for extra protection in the coldest zones.

Can I grow catmint in containers?

Absolutely. Compact varieties like ‘Junior Walker’ and ‘Little Titch’ thrive in pots. Use well-draining soil, ensure drainage holes, and water when the top inch of soil feels dry. Overwinter in an unheated garage in cold climates.

Why is my catmint floppy and falling over?

Floppy growth usually means too much shade, too much water, or too rich soil. Move to full sun, reduce watering, stop fertilizing, and shear back hard after the first bloom to encourage bushier, stronger stems.

What Is Catmint (Nepeta)?

Catmint belongs to the genus Nepeta, which includes roughly 250 species of flowering plants in the mint family, Lamiaceae. Native to Europe, Asia, and Africa, these aromatic perennials have naturalized in many parts of North America. The name “catmint” comes from the plant’s well-known attraction for felines, though not all species have the same effect.

Botanical Background

Like other mint family members, catmint features square stems, opposite leaves, and two-lipped tubular flowers. The foliage ranges from gray-green to deep green, often with a soft, fuzzy texture. When crushed, the leaves release a minty, slightly citrusy fragrance that many gardeners find delightful. The flowers appear in whorls along spikes, typically in shades of lavender, blue, pink, or white.

Growth Habit and Size

Most garden catmints form mounding clumps that spread slowly over time. Heights range from compact 12-inch varieties to statuesque 3-foot specimens. The spread typically matches or exceeds the height, creating a full, billowy presence in the garden. Unlike its aggressive cousin spearmint, catmint spreads by clumping rather than invasive runners, making it a well-behaved garden citizen.

Hardiness and Adaptability

Catmint shines in USDA zones 3 through 8, with some varieties pushing into zone 9. It handles cold winters with ease and tolerates summer heat when given adequate drainage. This adaptability makes it suitable for gardens across most of the United States. The plant’s deep taproot helps it survive dry spells, while its aromatic oils deter browsing animals.

Popular Varieties of Catmint

With so many species and cultivars available, choosing the right catmint can feel overwhelming. Here are the most popular and reliable options for home gardens.

Nepeta x faassenii – The Garden Classic

This hybrid group includes the most widely grown catmints. ‘Walker’s Low’ earned Perennial Plant of the Year honors in 2007 and remains a top choice. Despite the name, it reaches 24 to 30 inches tall with a similar spread. Lavender-blue flowers bloom from May through September with deadheading. ‘Junior Walker’ offers the same performance in a compact 15 to 18-inch package, perfect for smaller spaces.

Nepeta racemosa – Low-Growing Ground Covers

Species like ‘Little Titch’ and ‘Blue Wonder’ form dense mats just 8 to 12 inches tall. These work beautifully as edging plants, in rock gardens, or spilling over walls. ‘Little Titch’ produces deep blue flowers on a tight 10-inch mound, while ‘Blue Wonder’ spreads to 18 inches with prolific violet-blue blooms.

Nepeta subsessilis – The Moisture Lover

Unlike most catmints, this Japanese species tolerates and even prefers moister soil. ‘Sweet Dreams’ features pink flowers with dark calyxes on 18 to 24-inch plants. ‘Cool Cat’ offers pale lavender blooms on a compact 12-inch form. These varieties expand catmint’s range into damp meadow gardens and rain garden edges.

Nepeta sibirica – Tall and Stately

Siberian catmint reaches 3 to 4 feet tall with large, coarse leaves and dense violet-blue flower spikes. ‘Souvenir d’Andre Chaudron’ is a popular cultivar with a more refined habit. These taller types make striking back-of-border specimens but may need staking in rich soil.

Nepeta cataria – True Catnip

This is the species that drives cats wild. It’s less ornamental than hybrid catmints, with a rangy 3-foot habit and pale white flowers spotted with purple. Gardeners grow it primarily for feline entertainment or herbal use. It self-seeds readily and can become weedy.

Growing Catmint: Planting and Care

Success with catmint comes down to understanding its preferences. Give it what it likes, and it will reward you with months of color and fragrance.

Choosing the Right Location

Full sun produces the strongest growth and most flowers. Catmint tolerates light shade, especially in hot southern climates, but expect fewer blooms and a looser habit. Six to eight hours of direct sun is ideal. Good air circulation helps prevent fungal issues, so avoid cramped corners or dense plantings.

Soil Requirements

Well-drained soil is non-negotiable. Catmint rots in wet, heavy clay, especially during winter. Sandy or gravelly soil is perfect. If your soil is dense, amend with coarse sand, fine gravel, or compost to improve drainage. The plant prefers neutral to slightly alkaline pH (6.5 to 7.5) but adapts to mildly acidic conditions.

When and How to Plant

Spring planting after the last frost gives roots time to establish before summer heat. Fall planting works in zones 6 and warmer, allowing root growth during cool months. Space plants according to mature width: 18 to 24 inches for most varieties, 12 inches for dwarfs. Dig a hole twice the pot width, place the plant at the same depth it grew in the container, and backfill with native soil. Water thoroughly.

Watering Wisely

New plants need regular water for the first growing season. Once established, catmint is remarkably drought tolerant. Water deeply but infrequently, allowing soil to dry between waterings. Overwatering causes floppy growth and root rot. In most regions, established plants need supplemental water only during extended dry spells.

Fertilizing: Less Is More

Catmint thrives in lean soil. Rich soil or excessive fertilizer produces weak, floppy stems and fewer flowers. A light application of compost in spring is plenty. Avoid high-nitrogen fertilizers, which promote foliage at the expense of blooms. If your plant looks pale or stunted, a balanced slow-release fertilizer at half strength can help.

Deadheading for Continuous Bloom

This is the secret to months of flowers. After the first flush fades, shear the entire plant back by one-third to one-half. Use hedge shears or scissors for speed. This removes spent flowers and stimulates fresh growth and buds. You’ll see a second major bloom in 3 to 4 weeks. Repeat in midsummer for fall flowers. Stop deadheading 6 weeks before your first frost to allow hardening off.

Dividing and Transplanting

Every 3 to 4 years, clumps benefit from division. Early spring is best, just as new growth emerges. Dig the entire clump, shake off soil, and pull or cut into sections with healthy roots and shoots. Replant divisions immediately at the same depth. Water well. Division rejuvenates woody centers and gives you free plants.

Catmint vs Catnip: What’s the Difference?

This question confuses many gardeners. While related, these plants have distinct characteristics and uses.

Botanical Distinction

Catnip (Nepeta cataria) is a specific species. Catmint refers to ornamental Nepeta species and hybrids, primarily N. x faassenii, N. racemosa, and N. subsessilis. All contain nepetalactone, the compound that affects cats, but in vastly different concentrations.

Ornamental Value

Catmint wins hands down. Hybrid catmints offer dense, long-lasting blooms, attractive foliage, and tidy habits. Catnip looks weedy, with sparse pale flowers and a sprawling form. If you want a beautiful garden plant, choose catmint. If you want to entertain cats, catnip is more potent.

Cat Response

About 50 to 70 percent of cats respond to nepetalactone. The reaction is genetic. Kittens under 3 months and senior cats often show little interest. Catnip triggers the strongest response: rolling, rubbing, drooling, and hyperactivity lasting 10 to 15 minutes. Catmint elicits a milder reaction in responsive cats. Some cats ignore ornamental catmint entirely.

Growing Both

Many gardeners grow both. Plant catnip in a dedicated patch or container for cat access. Place ornamental catmint in display beds where you can enjoy the flowers. If neighborhood cats flatten your catmint, protect young plants with wire cages until established.

Benefits and Uses of Catmint

Beyond its good looks, catmint earns its keep in numerous ways.

Pollinator Paradise

Bees adore catmint. Honeybees, bumblebees, and native solitary bees work the flowers from dawn to dusk. Butterflies, especially skippers and swallowtails, visit regularly. Hummingbirds sip nectar from the tubular blooms. Planting catmint supports pollinator populations, which benefits your entire garden.

Deer and Rabbit Resistance

The aromatic oils that attract cats repel browsing mammals. Deer and rabbits rarely touch catmint, making it invaluable in areas with high wildlife pressure. Plant it as a protective border around more vulnerable plants. While no plant is completely deer-proof, catmint is among the most reliable.

Erosion Control

The dense, fibrous root system holds soil on slopes and banks. Low-growing varieties like ‘Little Titch’ form living mulch that prevents runoff. Combined with drought tolerance, this makes catmint ideal for difficult sunny slopes where irrigation is impractical.

Herbal and Household Uses

Catmint leaves make a pleasant, mildly sedative tea. Harvest leaves before flowering for best flavor. Dry them in a single layer away from direct sun. The dried leaves repel moths in closets and drawers. Some gardeners use catmint tea as a hair rinse for shine. Always research herbal uses thoroughly and consult a healthcare provider before medicinal use.

Cut Flowers and Arrangements

Catmint stems last 5 to 7 days in a vase. Cut when half the flowers on a spike are open. Strip lower leaves and place in cool water immediately. The airy texture complements roses, peonies, and other bold blooms. The fragrance adds a fresh note to indoor arrangements.

Container Gardening

Compact varieties thrive in pots. Use a well-draining mix with added perlite or grit. Ensure the container has drainage holes. Water when the top inch of soil feels dry. Fertilize monthly with half-strength balanced fertilizer. Overwinter pots in an unheated garage or bury them in the ground in cold climates.

Common Problems and Solutions

Catmint is trouble-free compared to most perennials, but a few issues can arise.

Floppy, Leggy Growth

This usually means too much shade, too much water, or too rich soil. Move to a sunnier spot, reduce watering, and stop fertilizing. Shear back hard after the first bloom to encourage bushier regrowth. Stake tall varieties early if needed.

Powdery Mildew

A white, powdery coating on leaves indicates this fungal disease. It appears in humid conditions with poor air circulation. Prevent it by spacing plants properly, watering at the base (not overhead), and choosing resistant varieties like ‘Walker’s Low’. Treat with neem oil or potassium bicarbonate spray at first sign.

Root Rot

Yellowing leaves, wilting despite moist soil, and blackened roots signal rot from poor drainage. Improve drainage immediately. If caught early, dig the plant, trim rotted roots, and replant in amended soil. Prevention through proper site selection is far easier than cure.

Spider Mites

These tiny pests thrive in hot, dry, dusty conditions. They cause stippled, bronzed leaves and fine webbing. Blast plants with a strong jet of water to dislodge mites. Insecticidal soap or horticultural oil controls severe infestations. Regular watering during dry spells discourages them.

Cat Damage

Enthusiastic cats can crush young plants. Protect new plantings with chicken wire cylinders or decorative plant supports until established. Mature plants usually recover from occasional feline attention. Consider planting a dedicated catnip patch nearby to divert traffic.

Designing with Catmint in the Landscape

Catmint’s versatility makes it a designer’s dream. Here are inspired ways to use it.

Perennial Borders

Plant catmint in drifts of 3, 5, or 7 for maximum impact. Its soft mounds contrast beautifully with spiky plants like salvia, veronica, or ornamental grasses. Pair with roses to hide bare canes and deter aphids. The lavender-blue flowers complement almost any color scheme.

Cottage Gardens

Catmint is a cottage garden staple. Let it self-sow gently among foxgloves, delphiniums, and hollyhocks. Its informal habit fits the relaxed aesthetic perfectly. Allow some seed heads to remain for winter interest and bird food.

Rock Gardens and Gravel Beds

Dwarf varieties excel in sharp drainage. Plant among sedums, thymes, and dwarf conifers. The gray-green foliage echoes stone colors. Catmint softens hard edges and fills gaps between rocks.

Pollinator Gardens

Create a season-long nectar source by combining catmint with early bloomers (catmint itself), mid-season stars (coneflower, bee balm), and late bloomers (sedum, aster). Add a water source and avoid pesticides.

Edging and Pathways

Low catmints define beds and soften hardscapes. Plant along walkways where brushing against them releases fragrance. They tolerate occasional foot traffic better than many edging plants.

Mediterranean and Xeric Gardens

Combine with lavender, rosemary, sage, and yarrow for a water-wise planting that evokes sunny hillsides. Mulch with gravel to reflect heat and improve drainage.

Seasonal Care Calendar

Follow this simple timeline for peak performance.

Early Spring (March-April)

• Cut back last year’s dead growth to 3-4 inches above ground
• Apply a thin layer of compost around plants
• Divide overcrowded clumps
• Plant new catmint after frost danger passes

Late Spring (May-June)

• First major bloom begins
• Monitor for pests
• Water new plantings regularly
• Enjoy the pollinator show

Early Summer (June-July)

• Deadhead or shear after first flush fades
• Water during dry spells
• Watch for powdery mildew in humid weather

Mid to Late Summer (August-September)

• Second bloom cycle
• Shear again if desired for fall flowers
• Stop fertilizing
• Reduce watering as temperatures cool

Fall (October-November)

• Leave foliage for winter protection
• Stop deadheading 6 weeks before frost
• Mulch lightly in cold zones after ground freezes
• Plant fall divisions in warm climates

Winter (December-February)

• Minimal care needed
• Brush heavy snow off to prevent breakage
• Plan next year’s additions
• Order new varieties early for best selection

Propagating Catmint

Expanding your catmint collection is easy and rewarding.

Division

As described earlier, division is the fastest way to get mature plants. Spring division yields blooming plants the same year. Fall division works in mild climates. Each division needs several shoots and a good root mass.

Stem Cuttings

Take 4 to 6-inch cuttings from non-flowering shoots in late spring or early summer. Strip lower leaves, dip in rooting hormone, and insert into moist perlite or sand. Cover with a plastic bag to maintain humidity. Roots form in 2 to 3 weeks. Pot up and grow on before planting out.

Seed

Species catmints come true from seed. Hybrids like ‘Walker’s Low’ produce variable offspring. Sow seeds indoors 6 to 8 weeks before last frost, or direct sow after frost. Barely cover seeds; they need light to germinate. Keep moist at 65 to 70°F. Germination takes 10 to 20 days.

Layering

Low-growing stems often root where they touch soil. Pin a stem down with a landscape staple, cover the contact point with soil, and keep moist. Roots form in a few weeks. Sever the new plant from the mother once rooted.

Catmint in Different Climates

Adapting care to your region ensures success.

Cool Climates (Zones 3-5)

Catmint thrives here. Winter hardiness is excellent. Plant in the warmest microclimate for earliest bloom. Mulch after ground freezes to prevent heaving. Spring cleanup can wait until new growth is obvious.

Mid-Atlantic and Midwest (Zones 6-7)

Ideal catmint country. Long bloom season, reliable return. Watch for humidity-related mildew in summer. Ensure good spacing and air flow.

Hot, Humid South (Zones 8-9)

Afternoon shade helps. Choose heat-tolerant varieties like ‘Walker’s Low’ and ‘Six Hills Giant’. Excellent drainage is critical. Expect a summer dormancy period with reduced flowering. Plants often rebound spectacularly in fall.

Arid West (Zones 5-9)

Catmint loves the dry air and intense sun. Irrigate deeply but infrequently. Mulch with gravel to conserve moisture. Watch for spider mites during extreme heat. Some afternoon shade benefits plants in lowest desert elevations.

Pacific Northwest (Zones 7-9)

Wet winters challenge catmint. Plant on mounds or in raised beds for drainage. Choose Nepeta subsessilis varieties for better wet tolerance. Full sun is essential to dry foliage quickly.

Companion Planting with Catmint

Strategic pairings enhance both beauty and garden health.

Rose Companions

Catmint is a classic rose underplanting. It hides thorny canes, attracts beneficial insects that prey on rose pests, and its shallow roots don’t compete deeply. The lavender-blue flowers create a stunning color echo with pink, yellow, or white roses.

Vegetable Garden Allies

Plant catmint near tomatoes, peppers, and eggplant. It may repel aphids, flea beetles, and squash bugs. The pollinators it attracts improve fruit set on cucurbits. Keep it at bed edges to avoid shading vegetables.

Herb Garden Partners

Combine with other Mediterranean herbs: lavender, thyme, oregano, sage. They share cultural needs and create a fragrant, useful planting. Catmint’s long bloom fills gaps when herbs are between flushes.

Ornamental Grass Pairings

Fine-textured grasses like Stipa tenuissima (Mexican feather grass) or Pennisetum (fountain grass) contrast beautifully with catmint’s mounded form. The combination moves gracefully in wind.

Bulb Companions

Plant catmint over spring bulbs (daffodils, tulips, alliums). As bulb foliage yellows, catmint’s fresh growth conceals it. The catmint blooms just as bulbs finish, extending the season.

Frequently Asked Questions About Catmint

Let’s address the most common questions gardeners ask.

Does catmint come back every year?

Yes, catmint is a hardy perennial that returns reliably in zones 3-8. The top growth dies back in winter, but the crown and roots survive underground. New shoots emerge from the base in spring.

How fast does catmint spread?

Catmint spreads slowly by expanding its clump, not by runners. Most varieties increase 6-12 inches per year. Division every 3-4 years controls size and rejuvenates the plant.

Can catmint grow in shade?

It tolerates light shade (4-6 hours sun) but flowers less and grows looser. In deep shade, it becomes leggy and prone to mildew. Full sun is strongly recommended.

Is catmint invasive?

No. Unlike true mints (Mentha), catmint does not spread by underground runners. It stays in a clump. Some species self-seed modestly, but seedlings are easy to remove or transplant.

When should I cut back catmint?

Cut back dead growth in early spring before new shoots appear. Shear after each bloom flush (by 1/3 to 1/2) to encourage rebloom. Stop cutting 6 weeks before frost.

Why is my catmint not flowering?

Common causes: too much shade, too much nitrogen fertilizer, overwatering, or the plant needs division. Ensure full sun, lean soil, and good drainage. Divide old, woody clumps.

Conclusion

Catmint plant nepeta truly offers something for everyone. Gardeners love its long bloom, easy care, and design versatility. Pollinators flock to its nectar-rich flowers. Cats enjoy its aromatic foliage. Even deer and rabbits respect its boundaries. Few perennials deliver so much value with so little demand.

Whether you choose a compact edger like ‘Little Titch’, a classic like ‘Walker’s Low’, or a tall statement plant like Siberian catmint, you’re adding a proven performer to your garden. Start with one plant, and you’ll likely find yourself making room for more. The soft lavender haze of catmint in full bloom, alive with the hum of bees, is one of gardening’s simple but profound pleasures.

Give catmint a sunny spot, well-drained soil, and an annual haircut. In return, you’ll get months of color, fragrance, and life. That’s a garden bargain worth making.

Frequently Asked Questions

Is catmint safe for cats to eat?

Yes, catmint is non-toxic to cats. Most cats enjoy rubbing against it or chewing the leaves. The effect is milder than catnip. Monitor your cat initially, as overindulgence may cause mild stomach upset in sensitive individuals.

How far apart should I plant catmint?

Space plants 18-24 inches apart for standard varieties like ‘Walker’s Low’. Dwarf varieties like ‘Little Titch’ need 12-15 inches. Proper spacing ensures good air circulation, which prevents powdery mildew.

Can catmint be grown from seed?

Species catmints grow true from seed, but named cultivars like ‘Walker’s Low’ produce variable offspring. For consistent results, propagate cultivars by division or cuttings. Seeds need light to germinate and take 10-20 days at 65-70°F.

Does catmint repel mosquitoes?

Catmint contains nepetalactone, which research shows repels mosquitoes more effectively than DEET in laboratory settings. However, simply growing the plant in your garden provides minimal protection. Crushing leaves and applying oils directly works better.

When is the best time to divide catmint?

Early spring, just as new growth emerges, is ideal. The plant recovers quickly and often blooms the same year. Fall division works in zones 6 and warmer. Divide every 3-4 years when the center becomes woody and flower production declines.

What causes yellow leaves on catmint?

Yellow leaves usually indicate overwatering or poor drainage leading to root rot. Catmint prefers dry conditions. Less commonly, it signals nutrient deficiency in very poor soil. Check soil moisture and drainage first, then consider a light compost application.
