Best Catmint Plants

Catmint (Nepeta) is a drought-tolerant perennial that blooms for months with lavender-blue flowers. This guide covers the best catmint varieties for every garden, from compact border plants to tall statement pieces. Learn how to choose, plant, and care for catmint to attract pollinators and enjoy season-long color.

If you have ever walked past a garden in early summer and noticed a cloud of lavender-blue flowers buzzing with bees, chances are you were looking at catmint. This tough perennial has earned its place in gardens across the country for good reason. It blooms for months. It laughs at drought. Deer and rabbits leave it alone. And it asks for almost nothing in return.

But not all catmint plants are created equal. Some sprawl like lazy cats in the sun. Others stand tall and tidy. Some bloom once and call it a season. Others keep going until frost with a little help from your pruning shears. Choosing the right variety makes the difference between a plant that thrives and one that merely survives. This guide walks you through the best catmint plants for every garden situation so you can pick the perfect match for your space.

Key Takeaways

• Walker’s Low is the gold standard: This award-winning variety offers reliable performance, long bloom time, and a manageable size for most gardens.
• Catmint thrives on neglect: Once established, these plants need little water, no fertilizer, and minimal maintenance to look their best.
• Different varieties serve different purposes: Compact types like ‘Cat’s Pajamas’ work in containers, while taller ones like ‘Six Hills Giant’ create dramatic backdrops.
• Pollinators love catmint: Bees, butterflies, and hummingbirds flock to the nectar-rich flowers all season long.
• Shearing after first bloom triggers rebloom: Cut plants back by half in midsummer for a fresh flush of flowers in fall.
• Catmint repels pests naturally: The aromatic foliage deters deer, rabbits, and many insect pests from nearby plants.
• Well-drained soil is non-negotiable: Catmint rots in wet clay; amend heavy soils or plant in raised beds for success.

Quick Answers to Common Questions

What is the difference between catmint and catnip?

Catmint (Nepeta x faassenii and hybrids) is an ornamental perennial grown for flowers and foliage. Catnip (Nepeta cataria) is a weedy herb grown for cats. Both contain nepetalactone, but catmint is well-behaved in gardens while catnip spreads aggressively.

When should I cut back catmint?

Shear catmint back by half in early to mid-July after the first flush of flowers fades. This triggers a fresh bloom cycle for fall. Cut dead stems to the ground in late winter or early spring before new growth emerges.

Does catmint come back every year?

Yes, catmint is a hardy perennial that returns reliably in USDA zones 3-8. It dies back to the ground in winter and resprouts from the crown in spring. Good drainage is essential for winter survival.

Can catmint grow in shade?

Catmint needs full sun (6+ hours) to bloom well and stay compact. In shade, it becomes leggy, flowers poorly, and flops over. For shady areas, choose shade-tolerant perennials like hostas or ferns instead.

Is catmint invasive?

Named catmint cultivars like ‘Walker’s Low’ are clump-forming and not invasive. They spread slowly by underground stems but do not run rampant. Species types may self-seed modestly. Deadheading prevents unwanted seedlings.

Understanding Catmint: What Makes Nepeta Special

Before we dive into specific varieties, let’s clear up a common point of confusion. Catmint (Nepeta) is not the same as catnip (Nepeta cataria). Both belong to the mint family. Both contain nepetalactone, the compound that sends cats into euphoric rolls. But catnip is a weedy, aggressive spreader grown for feline entertainment. Catmint is a well-behaved ornamental perennial grown for beauty and pollinator support.

The Botany Behind the Beauty

Catmint species hail from Europe, Asia, and Africa. Most garden varieties are hybrids of Nepeta racemosa and Nepeta nepetella. These plants form mounds of aromatic, gray-green foliage. The leaves release a minty, slightly citrusy scent when brushed. From late spring through summer, spikes of tubular flowers rise above the foliage in shades of lavender, blue, violet, pink, or white.

The flowers are small but numerous. Each spike holds dozens of blooms that open sequentially. This extends the show for weeks. Bees adore them. Butterflies use them as landing pads. Hummingbirds dart between the spikes for nectar. The plant’s long bloom period makes it a pollinator powerhouse when many other perennials have finished flowering.

Why Gardeners Keep Coming Back

Catmint checks almost every box for a low-maintenance perennial. It is hardy in USDA zones 3 through 8, with some varieties stretching to zone 9. It tolerates poor soil, heat, humidity, and drought once established. It resists most diseases. The only real enemy is wet feet. Plant it in heavy clay that stays soggy, and you will lose it to root rot.

The aromatic oils that make catmint pleasant to humans also repel deer, rabbits, and many insect pests. This makes it an excellent companion plant for roses, vegetables, and other tasty targets. Plant a border of catmint around your rose bed, and you create a fragrant barrier that pests prefer to avoid.

Top Catmint Varieties for Every Garden

With dozens of named cultivars on the market, choosing can feel overwhelming. The following varieties represent the best of the best. Each has proven itself in trial gardens and real-world landscapes across multiple climates.

Walker’s Low: The Reliable Classic

If you buy only one catmint, make it ‘Walker’s Low.’ This cultivar won the Perennial Plant Association’s Plant of the Year award in 2007, and it has not relinquished its crown. Despite the name, ‘Walker’s Low’ is not a groundcover. It forms a mounded clump 24 to 30 inches tall and wide. The name honors the garden where it was discovered, not its stature.

Deep lavender-blue flowers appear in late May and continue through July. A hard shearing after the first flush brings a second bloom in late summer that often lasts until frost. The foliage stays attractive all season, resisting the summer slump that plagues some perennials. ‘Walker’s Low’ is sterile, so it will not self-seed aggressively. It spreads slowly by underground stems, forming a polite clump that plays well with neighbors.

This variety excels in the middle of a sunny border, along a walkway, or massed on a slope for erosion control. It pairs beautifully with roses, salvias, coneflowers, and ornamental grasses. The silver-green foliage provides a cooling contrast to hot-colored flowers like red yarrow or orange butterfly weed.

Cat’s Pajamas: Compact Powerhouse

Not every garden has room for a three-foot perennial. Enter ‘Cat’s Pajamas,’ a Proven Winners introduction that packs full-size flower power into a tidy 12-to-14-inch mound. This variety was bred for container culture and small spaces, but it performs equally well in the ground.

The flowers are a rich indigo-blue, darker than most catmints. They appear earlier than ‘Walker’s Low,’ often starting in mid-May. The bloom density is incredible. A mature plant in full flower looks like a solid dome of color with barely a leaf visible. Like its larger cousins, ‘Cat’s Pajamas’ reblooms reliably after shearing.

Use this variety at the front of borders, in rock gardens, or in mixed containers. It makes a stunning “thriller” component in a large pot surrounded by trailing petunias or sweet potato vine. The compact habit means no flopping, even after heavy rain. For gardeners with limited space or those gardening on balconies and patios, ‘Cat’s Pajamas’ delivers disproportionate impact.

Six Hills Giant: The Statement Maker

When you need height and presence, ‘Six Hills Giant’ answers the call. This venerable cultivar dates back to the 1960s and remains a favorite for the back of the border. It reaches 36 to 48 inches tall and spreads 30 to 36 inches wide. The flower spikes are longer and more substantial than those of smaller varieties, creating a hazy cloud of violet-blue above the foliage.

The trade-off for this stature is a slightly later start. ‘Six Hills Giant’ typically begins blooming in early June, a week or two behind ‘Walker’s Low.’ The foliage is larger and coarser, with a more pronounced gray cast. This variety benefits from staking in rich soil or windy sites, as the heavy flower heads can bow under their own weight.

Plant ‘Six Hills Giant’ where it has room to breathe. It makes a magnificent backdrop for shorter perennials like coreopsis, dwarf coneflowers, or sedums. The vertical flower spikes add architectural interest to meadow-style plantings. Pair it with tall ornamental grasses like ‘Karl Foerster’ feather reed grass for a dynamic late-summer vignette.

Junior Walker: The Middle Ground

Can’t decide between ‘Walker’s Low’ and ‘Cat’s Pajamas’? ‘Junior Walker’ splits the difference. This sport of ‘Walker’s Low’ reaches 18 to 24 inches tall and wide. It retains the long bloom season and rebloom reliability of its parent but in a more compact package that rarely needs staking.

The flower color is a soft lavender-blue, slightly lighter than ‘Walker’s Low.’ The foliage is finer textured, giving the plant a softer overall appearance. ‘Junior Walker’ blooms heavily in late spring, takes a brief pause in midsummer heat, then rebounds with vigor in fall. It is an excellent choice for the middle of a mixed border where you want substance without bulk.

Little Trudy: Dwarf Charm for Rock Gardens

For the rock garden, trough, or alpine bed, ‘Little Trudy’ (also sold as ‘Psfike’) is a standout. This Plant Select winner forms a tight mound just 8 to 10 inches tall and 12 to 15 inches wide. The leaves are smaller and more densely packed than other varieties, giving it a neat, cushiony look even out of bloom.

Bright lavender-pink flowers appear in late spring, a welcome color variation from the usual blue palette. The bloom period is shorter than larger catmints, typically four to six weeks, but the intensity is remarkable. ‘Little Trudy’ appreciates sharp drainage and lean soil. Rich conditions produce lush foliage at the expense of flowers.

This variety shines in crevices between stones, along the edge of a gravel path, or in a hypertufa trough. It pairs well with other drought-tolerant miniatures like creeping thyme, sedums, and dwarf penstemons. In humid climates, give it extra air circulation to prevent fungal issues on the dense foliage.

Blue Wonder: Early and Profuse

‘Blue Wonder’ earns its name with an avalanche of deep violet-blue flowers starting in mid-May, often two weeks earlier than ‘Walker’s Low.’ The plant reaches 18 to 24 inches tall and spreads to 30 inches. The flower spikes are held well above the foliage, creating a layered effect that catches the light beautifully.

This variety is a selection of Nepeta racemosa, one of the parent species of many modern hybrids. It has a slightly wilder, more naturalistic habit than the polished hybrids. The foliage is a true gray-green, not silvered. ‘Blue Wonder’ self-seeds modestly in favorable conditions. The seedlings are easy to remove or transplant.

Use ‘Blue Wonder’ in cottage gardens, pollinator meadows, or naturalized areas where a looser look is welcome. It combines beautifully with early-blooming perennials like baptisia, peonies, and alliums. The early bloom fills the gap between spring bulbs and summer perennials, keeping the garden colorful during the “June gap.”

Pink Cat: Breaking the Blue Mold

Most catmints bloom in shades of blue and lavender. ‘Pink Cat’ (sometimes sold as ‘Pink Dreams’) offers a refreshing alternative with soft pink flowers. The color is subtle, more blush than hot pink, but it stands out in a sea of blue. The plant grows 18 to 24 inches tall and wide with a relaxed, slightly sprawling habit.

The bloom season mirrors ‘Walker’s Low,’ starting in late May and reblooming after shearing. The foliage is a lighter green than most varieties, less gray. ‘Pink Cat’ is a bit more heat-sensitive in southern zones, appreciating afternoon shade in zones 8 and 9. In cooler climates, full sun produces the best flowering.

This variety opens design possibilities. Pair it with blue catmints for a tonal gradient. Combine it with white flowers like ‘Becky’ shasta daisy for a classic pastel palette. Use it near roses with pink or apricot blooms for a harmonious color echo. ‘Pink Cat’ proves that catmint does not have to be blue to be beautiful.

Felix: The New Contender

Released in 2021, ‘Felix’ represents the latest breeding advances. This variety was selected for extreme flower density, compact habit, and heat tolerance. It reaches just 14 to 16 inches tall and wide but produces flower spikes that nearly obscure the foliage at peak bloom. The color is a saturated violet-blue that reads as purple from a distance.

‘Felix’ begins blooming in early May in warm climates, late May farther north. It reblooms vigorously without deadheading, though shearing still improves the fall show. The foliage is exceptionally clean, resisting the leaf spot that can mar older varieties in humid summers. This variety was bred for the Southeast but performs well across a wide range.

For gardeners in hot, humid climates who have struggled with catmint melting out in August, ‘Felix’ offers hope. Its breeding includes genetics from southern-adapted species. Try it in the front of the border, in mass plantings, or in containers where its tidy habit shines.

Choosing the Right Catmint for Your Conditions

Matching the plant to your site saves frustration and ensures success. Consider these factors when selecting among the best catmint plants.

Sun Exposure Requirements

Catmint demands full sun. That means at least six hours of direct sunlight daily. Eight to ten hours is even better. In hot southern climates, some varieties tolerate light afternoon shade, but flowering decreases proportionally. ‘Pink Cat’ and ‘Felix’ handle heat better than most. ‘Six Hills Giant’ and ‘Walker’s Low’ are more sun-demanding.

If your site gets only four to five hours of sun, catmint will survive but not thrive. The plants become leggy, flower poorly, and flop over. In shade, the aromatic oils diminish, reducing pest resistance. For shadier spots, consider alternatives like Japanese forest grass, hostas, or ferns.

Soil Preferences and Drainage

This is the make-or-break factor. Catmint needs sharp drainage. Sandy or gravelly soil is ideal. Loam works if it does not stay wet. Heavy clay is a death sentence unless amended extensively or planted in raised beds. The roots cannot tolerate sitting in water, especially in winter.

Test your drainage by digging a hole 12 inches deep and filling it with water. If it drains in under an hour, you are good. If it takes several hours, amend with coarse sand, fine gravel, or expanded shale. Do not use fine sand. It creates concrete-like soil when mixed with clay. Organic matter helps but does not fix fundamental drainage issues.

Soil fertility should be low to moderate. Rich soil produces lush, floppy growth with fewer flowers. Do not fertilize catmint. A light top-dressing of compost in spring is plenty. If you must fertilize, use a slow-release, low-nitrogen formula at half the recommended rate.

Climate and Hardiness Considerations

Most catmints are hardy to zone 3 (-40°F) or zone 4 (-30°F). The limiting factor in cold climates is not temperature but winter wet. Plants in well-drained soil survive extreme cold. Plants in wet soil rot. In zones 3 and 4, apply a light mulch of pine needles or shredded leaves after the ground freezes. Remove it in early spring.

In hot climates (zones 8 and 9), the challenge is summer heat and humidity. ‘Felix,’ ‘Pink Cat,’ and ‘Junior Walker’ show better heat tolerance. Provide afternoon shade in the deep South. Ensure excellent air circulation to prevent fungal diseases. Mulch with gravel rather than organic material to keep the crown dry.

Space and Scale

Check the mature dimensions before planting. ‘Six Hills Giant’ needs a three-foot diameter. ‘Walker’s Low’ needs two feet. ‘Cat’s Pajamas’ and ‘Felix’ fit in a one-foot circle. ‘Little Trudy’ needs just 15 inches. Crowding leads to poor air circulation, disease, and competition for resources.

Consider the plant’s role in your design. Do you need a tall backdrop? Choose ‘Six Hills Giant.’ A mid-border workhorse? ‘Walker’s Low’ or ‘Junior Walker.’ A front-of-border edger? ‘Cat’s Pajamas’ or ‘Blue Wonder.’ A rock garden gem? ‘Little Trudy.’ A container specimen? ‘Cat’s Pajamas’ or ‘Felix.’

Planting and Establishment: Getting Off to a Strong Start

Even the best catmint plants need proper installation to reach their potential. The effort you invest at planting pays dividends for years.

When to Plant

Spring and fall are both excellent planting times. Spring planting gives the roots a full season to establish before winter. Fall planting takes advantage of cooler temperatures and autumn rains. In zones 3 through 6, spring is safer. In zones 7 through 9, fall is often better because the roots grow through winter.

Avoid planting in the heat of summer. If you must, provide temporary shade and water frequently until established. Container-grown plants can be planted any time the ground is not frozen, but they need more attention during extreme weather.

Planting Technique

Dig a hole twice as wide as the root ball but no deeper. The top of the root ball should sit level with or slightly above the surrounding soil. Planting too deep buries the crown and invites rot. If your soil is heavy, plant an inch high and mound soil up to the root ball to improve drainage.

Remove the plant from its pot. Loosen circling roots gently. If the root ball is a solid mass, make three or four vertical cuts with a knife to encourage outward growth. Place the plant in the hole. Backfill with native soil. Do not amend the backfill. Amending creates a “bathtub effect” where water collects in the improved soil.

Water thoroughly to settle the soil and eliminate air pockets. Apply a thin layer of gravel mulch or shredded bark. Keep mulch away from the crown. Water every two to three days for the first two weeks, then weekly for the first growing season unless rain provides an inch per week.

Spacing Guidelines

Space plants according to their mature width, not their current pot size. ‘Walker’s Low’ and ‘Junior Walker’: 24 to 30 inches apart. ‘Six Hills Giant’: 36 to 42 inches. ‘Cat’s Pajamas’ and ‘Felix’: 14 to 18 inches. ‘Blue Wonder’: 24 to 30 inches. ‘Little Trudy’: 12 to 15 inches.

For mass plantings, use the closer spacing. For specimen plants, use wider spacing. Stagger rows in a triangular pattern for a natural look. This creates full coverage faster than straight rows.

Ongoing Care: Keeping Catmint Looking Its Best

Catmint is low-maintenance, not no-maintenance. A few timely interventions keep plants blooming and shapely.

The Shearing Secret: How to Get Months of Bloom

This is the single most important maintenance task. Most catmints bloom heavily in late spring to early summer, then slow down. By midsummer, the flower spikes turn brown and the foliage looks tired. Shearing the entire plant back by half triggers a fresh flush of growth and flowers.

Time the shearing for when the first bloom is about 80 percent finished. This is usually early to mid-July. Use hedge shears or a string trimmer for large plantings. Cut the whole mound back to 6 to 12 inches, depending on the variety’s height. Remove all the spent flower stems and the top layer of foliage.

Water well after shearing. Apply a light side-dressing of compost if the soil is poor. Within two weeks, new growth emerges. By late August, the plant is covered in flower buds. The fall bloom is often more intense than the spring bloom because the plant is larger. This technique works on all varieties except ‘Little Trudy,’ which prefers a lighter trim.

Watering Wisdom

New plants need regular water. Established plants need almost none. After the first full season, catmint is remarkably drought-tolerant. The deep taproots access moisture far below the surface. In fact, overwatering causes more problems than underwatering.

Water deeply but infrequently. Once every two to three weeks in summer is plenty for established plants in most climates. In extreme heat or sandy soil, weekly watering may help. Never water daily. Frequent shallow watering encourages surface roots that dry out quickly.

Stop watering in early fall to help plants harden off for winter. Wet soil going into winter is the primary cause of loss in cold climates.

Fertilizing: Less Is More

Do not fertilize catmint. Seriously. Nitrogen promotes soft, floppy growth that falls apart in rain. It also reduces essential oil production, diminishing pest resistance and fragrance. If your soil is extremely poor (pure sand or construction fill), a single application of slow-release 5-10-5 fertilizer in early spring at quarter strength is acceptable.

Compost is better than fertilizer. A half-inch top-dressing around the base in spring feeds slowly and improves soil structure. Keep compost away from the crown.

Dividing: When and How

Catmint does not require regular division like some perennials. Clumps can remain undivided for five to seven years. Divide when the center dies out, flowering declines, or the plant outgrows its space. Spring is the best time, just as new growth emerges. Fall works in mild climates.

Dig the entire clump. Shake off excess soil. Use a sharp spade or knife to cut the clump into sections, each with several shoots and healthy roots. Discard the woody center. Replant divisions immediately at the same depth. Water well. They may look rough for a few weeks but recover quickly.

Pest and Disease Management

Catmint is remarkably trouble-free. The main issues are fungal diseases in humid conditions with poor air circulation. Powdery mildew appears as white dust on leaves. Leaf spot causes brown lesions. Both are cosmetic and rarely fatal.

Prevent problems by spacing properly, avoiding overhead watering, and removing affected leaves. In severe cases, shear the plant to the ground after bloom. It will regrow clean foliage. Root rot from poor drainage is the only serious threat. Prevention through proper planting is the only cure.

Aphids occasionally cluster on new growth. Blast them off with a strong jet of water. Spider mites appear in hot, dry weather. Increase humidity with occasional overhead watering (morning only). Cats may roll on young plants. Protect new plantings with chicken wire cages for the first month.

Designing with Catmint: Creative Combinations

The best catmint plants shine in thoughtful combinations. Their soft texture, long bloom, and aromatic foliage make them versatile design elements.

Classic Perennial Partners

Roses and catmint are a legendary pairing. The catmint hides the rose’s bare legs, repels pests, and blooms in sync with the first rose flush. ‘Walker’s Low’ is the perfect height for most shrub roses. Plant it 18 inches from the rose base.

Salvias share catmint’s cultural needs and bloom time. ‘May Night’ salvia’s deep purple spikes contrast beautifully with catmint’s lavender haze. Both rebloom after shearing. Plant them in alternating drifts for a river of blue.

Coneflowers (Echinacea) pick up where catmint leaves off. As catmint’s spring bloom fades, coneflowers hit their stride. The seed heads provide winter interest after catmint is cut back. Choose compact coneflowers like ‘PowWow Wild Berry’ to match ‘Junior Walker’ or ‘Cat’s Pajamas.’

Ornamental grasses add movement and winter structure. ‘Karl Foerster’ feather reed grass rises above ‘Six Hills Giant.’ Little bluestem (Schizachyrium scoparium) complements ‘Walker’s Low’ with its blue-green summer foliage and copper fall color.

Pollinator Garden Essentials

Catmint is a cornerstone of pollinator gardens. Plant it in drifts of five or more for maximum impact. Bees forage more efficiently on large patches. Include early, mid, and late-season bloomers to support pollinators all year.

Spring: Catmint, baptisia, alliums, salvia. Summer: Coneflowers, bee balm, butterfly weed, black-eyed Susans. Fall: Asters, goldenrod, sedum, joe-pye weed. Catmint bridges spring and summer. The fall rebloom bridges summer and fall.

Add a water source (shallow dish with stones), nesting sites (bare ground, bee houses), and host plants for butterfly larvae (milkweed for monarchs, parsley for swallowtails). Avoid pesticides entirely.

Edging and Border Solutions

Catmint makes a superb edging plant for paths and beds. The foliage stays attractive all season. The flowers spill softly over hardscape edges. ‘Cat’s Pajamas’ and ‘Junior Walker’ are the best choices for formal edges. They hold their shape without flopping.

For a looser cottage garden look, let ‘Walker’s Low’ or ‘Blue Wonder’ billow over a stone wall or path edge. The casual habit reinforces the informal style. Shear the path-side growth if it obstructs passage.

Slope and Erosion Control

The spreading root systems of catmint stabilize slopes beautifully. ‘Walker’s Low’ and ‘Six Hills Giant’ are the workhorses here. Plant them in a grid pattern 24 inches apart on center. They will knit together in two to three years.

Combine with other slope-stabilizers like creeping juniper, cotoneaster, or ornamental grasses. The catmint provides quick coverage and flowers while slower woody plants establish.

Container Culture

‘Cat’s Pajamas,’ ‘Felix,’ and ‘Little Trudy’ thrive in containers. Use a pot at least 12 inches wide and deep. Fill with a gritty mix: two parts potting soil, one part coarse sand or perlite, one part compost. Ensure drainage holes are ample.

Water when the top inch of soil is dry. Fertilize monthly with half-strength balanced liquid fertilizer during active growth. Overwinter containers in an unheated garage or bury the pot in the ground. In zones 7 and warmer, containers can stay outdoors with minimal protection.

Troubleshooting Common Catmint Problems

Even with the best catmint plants, issues occasionally arise. Here is how to diagnose and fix them.

Flopping and Leggy Growth

Cause: Too much shade, too much water, too much fertilizer, or overcrowding. Fix: Move to full sun. Stop fertilizing. Reduce watering. Divide or thin crowded clumps. Shear hard in early summer to promote bushier growth. Stake tall varieties early if needed.

Poor Flowering

Cause: Insufficient sun, excess nitrogen, plant too young, or wrong variety for climate. Fix: Ensure six-plus hours of sun. Stop fertilizing. First-year plants often bloom lightly. In hot climates, choose heat-tolerant varieties like ‘Felix’ or ‘Pink Cat.’

Center Die-Out

Cause: Age, poor drainage, or winter wet. Fix: Divide in spring, discarding the dead center. Improve drainage if needed. Mulch with gravel, not organic matter, to keep crown dry.

Yellowing Leaves

Cause: Overwatering, poor drainage, or nutrient deficiency (rare). Fix: Check soil moisture. Reduce watering. If drainage is poor, consider lifting and replanting in a raised bed. A soil test can identify deficiencies.

Powdery Mildew

Cause: Humidity, poor air circulation, overhead watering. Fix: Thin plants to improve airflow. Water at soil level. Shear affected growth. Apply neem oil or potassium bicarbonate spray if severe. Choose resistant varieties like ‘Felix’ in humid climates.

Catmint Through the Seasons

Understanding the annual cycle helps you anticipate needs and appreciate the plant’s full contribution.

Spring Awakening

New growth emerges from the crown in early spring as a fountain of gray-green leaves. This is the time to remove last year’s dead stems. Cut them to the ground before new growth gets tall. Apply compost top-dressing if desired. Watch for early aphids on tender shoots.

Early Summer Glory

Late May through June brings the main bloom event. The plant becomes a magnet for pollinators. Enjoy the show. Deadhead individual spent spikes if you are fastidious, but shearing later is more efficient.

Midsummer Maintenance

July brings the shearing. This feels brutal but is essential. The plant looks like a buzz cut for two weeks. Then fresh growth explodes. This is also the time to check for pests and diseases.

Fall Encore

August through October delivers the second bloom. It is often more profuse than the first because the plant is larger. The flowers combine beautifully with fall-blooming perennials and grasses. Stop watering in early fall.

Winter Rest

After hard frost, the foliage collapses. Leave it in place. The dead stems protect the crown and provide habitat for beneficial insects. In late winter or early spring, cut back to the ground before new growth starts.

Propagation: Making More of a Good Thing

Once you find a variety you love, you will want more. Catmint propagates easily by several methods.

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 should have three to five shoots.

Stem Cuttings

Take softwood cuttings in late spring or early summer. Cut 4-to-6-inch stems just below a node. Remove lower leaves. Dip in rooting hormone (optional but helpful). Stick in moist perlite or sand. Cover with a plastic bag. Roots form in three to four weeks. Pot up and grow on.

Seed

Species catmints come true from seed. Hybrids do not. If you want a specific cultivar, buy plants or divide. If you want to experiment, collect seed from species types like Nepeta racemosa or Nepeta sibirica. Sow in spring. Seedlings vary.

Layering

Low-growing stems often root where they touch soil. Pin a stem down with a landscape staple. Cover the contact point with soil. Check for roots in a few months. Sever and transplant.

Catmint for Specific Challenges

Certain garden situations call for specific catmint solutions.

Deer and Rabbit Pressure

All catmints resist browsing, but ‘Walker’s Low,’ ‘Six Hills Giant,’ and ‘Junior Walker’ have the highest essential oil content. Plant them as a perimeter barrier around vulnerable plants. The scent masks the aroma of tasty neighbors.

Hell Strips and Parking Strips

The narrow strip between sidewalk and street tests any plant. Heat, salt, compaction, and foot traffic are brutal. ‘Cat’s Pajamas’ and ‘Junior Walker’ tolerate these conditions better than most. Their compact size avoids sight-line issues.

Seaside Gardens

Salt spray kills many perennials. Catmint tolerates moderate salt. ‘Walker’s Low’ and ‘Blue Wonder’ perform well in coastal gardens. Plant them back from the first line of dunes. Rinse foliage with fresh water after storms.

Fire-Prone Areas

Catmint is not fire-resistant. The dry stems and aromatic oils are flammable. In fire zones, keep catmint 30 feet from structures. Remove dead growth promptly. Choose irrigated locations.

Buying Guide: What to Look For

Smart shopping ensures you bring home healthy plants that establish quickly.

Where to Buy

Local independent nurseries often carry the best selection of regionally appropriate varieties. The staff knows what works in your climate. Specialty perennial nurseries offer the widest variety, including newer introductions like ‘Felix.’ Big-box stores have lower prices but limited selection and variable quality.

Mail-order nurseries ship bare-root or small pots in spring. This is a great way to get unusual varieties. Order early for best selection. Inspect plants immediately on arrival.

Evaluating Plant Health

Look for vigorous, bushy growth. Avoid plants with yellowing leaves, leggy stems, or roots circling the pot bottom. Check for pests on leaf undersides. The crown should be firm, not mushy. A few spent flower stems are fine; they indicate the plant has bloomed and is mature.

Pot Size vs. Value

Quart pots (4-inch) are the sweet spot for perennials. They establish fast and cost less than gallons. Plugs (2-inch) are economical for mass plantings but need a season to bulk up. Gallon pots give instant impact but cost three to four times more.

Reading Labels

Check the tag for variety name, hardiness zone, mature size, and sun requirement. Some retailers sell generic “catmint” without a cultivar name. These are often seed-grown and variable. Named cultivars guarantee consistent performance.

Conclusion: Your Garden Deserves Catmint

Few perennials deliver as much beauty for as little effort as catmint. From the compact charm of ‘Cat’s Pajamas’ to the statuesque presence of ‘Six Hills Giant,’ there is a catmint for every sunny spot. The long bloom season feeds pollinators when they need it most. The aromatic foliage solves pest problems naturally. The drought tolerance makes it a climate-smart choice for an uncertain future.

Start with one variety that matches your space and style. ‘Walker’s Low’ is the safest bet for most gardens. ‘Cat’s Pajamas’ wins for small spaces and containers. ‘Six Hills Giant’ dominates the back of the border. Plant it well. Shear it in July. Enjoy months of lavender-blue clouds buzzing with life.

Your garden will thank you. The bees will thank you. And you will wonder how you ever gardened without it.

Frequently Asked Questions

How do I get my catmint to bloom all summer?

Shear the plant back by half in early July after the first bloom finishes. Water well afterward. This triggers fresh growth and a second heavy bloom period from August through frost. Most varieties respond vigorously to this treatment.

Why is my catmint flopping over?

Flopping usually means too much shade, water, or fertilizer. Catmint prefers lean, dry conditions in full sun. Move it to a sunnier spot, stop fertilizing, and reduce watering. Shearing in early summer also promotes sturdier, bushier growth.

Can I grow catmint in a pot?

Yes, compact varieties like ‘Cat’s Pajamas,’ ‘Felix,’ and ‘Little Trudy’ thrive in containers. Use a 12-inch pot with gritty, well-draining soil. Water when the top inch is dry. Fertilize monthly at half strength. Overwinter in an unheated garage in cold climates.

Will catmint survive winter in zone 4?

Absolutely. Most catmints are hardy to zone 3 (-40°F). The key is drainage. Wet winter soil kills more catmint than cold. Plant in well-drained soil or raised beds. Apply light pine needle mulch after the ground freezes.

Do I need to deadhead catmint?

Deadheading individual spent spikes is optional and tedious. The efficient method is shearing the whole plant by half in midsummer. This removes all spent flowers at once and stimulates rebloom. Skip deadheading; just shear in July.

What plants pair well with catmint?

Roses, salvias, coneflowers, ornamental grasses, black-eyed Susans, butterfly weed, and sedums all complement catmint beautifully. They share similar sun and soil needs. Catmint’s soft texture contrasts nicely with bold foliage and spiky flowers.
