Why Grow Catmint Plant

Catmint is a garden superstar that offers stunning purple-blue blooms, aromatic foliage, and incredible wildlife value with almost zero maintenance. This drought-tolerant perennial thrives in poor soil, blooms for months, and supports bees, butterflies, and hummingbirds while naturally repelling deer, rabbits, and mosquitoes.

If you have ever walked past a garden buzzing with bees and butterflies while a soft lavender-blue haze dances in the breeze, chances are you have met catmint. This unassuming perennial goes by the botanical name Nepeta, and it might just be the hardest working plant in your garden. I first discovered catmint years ago when I was a frustrated beginner gardener watching my fussy roses succumb to black spot and my hydrangeas wilt in the afternoon sun. A neighbor handed me a division of ‘Walker’s Low’ and said, “Plant this. Ignore it. Thank me later.” She was right.

Catmint belongs to the mint family, Lamiaceae, which explains its square stems, aromatic leaves, and spreading habit. But unlike its aggressive culinary cousins, garden catmint forms tidy mounds that stay where you put them. The genus includes roughly 250 species, but only a handful are commonly grown in gardens. Most popular varieties are hybrids of Nepeta racemosa and Nepeta nepetella, bred for longer bloom times, sterile seeds, and compact forms. Whether you call it catmint, catnip’s sophisticated cousin, or simply Nepeta, this plant earns its keep in ways few perennials can match.

Key Takeaways

• Long blooming season: Catmint flowers from late spring through fall, providing months of continuous color in the garden.
• Pollinator magnet: Bees, butterflies, and hummingbirds flock to the nectar-rich tubular flowers all season long.
• Drought tolerant: Once established, catmint thrives on neglect and requires minimal watering even in hot summers.
• Pest and deer resistant: The aromatic oils in the foliage naturally repel deer, rabbits, and many insect pests.
• Low maintenance: No deadheading required, minimal fertilizing, and only occasional division keeps plants vigorous.
• Versatile design uses: Works beautifully in borders, rock gardens, containers, and as edging along pathways.
• Herbal and household uses: Leaves can be harvested for calming teas, cat toys, and natural insect repellent sachets.

Quick Answers to Common Questions

Does catmint attract cats like catnip does?

Yes, but the effect is milder. About 50 to 70 percent of cats respond to catmint, showing behaviors like rolling, rubbing, and mild euphoria for 10 to 20 minutes. Catnip (Nepeta cataria) produces a stronger reaction.

When is the best time to cut back catmint?

Shear plants back by half in early July after the first heavy bloom flush finishes. This triggers fresh growth and a second massive flower display. Cut dead stems to the ground in early spring before new growth emerges.

Can catmint grow in shade?

Catmint needs at least six hours of direct sun for best flowering and compact growth. In partial shade (four to six hours), plants become leggy, flop open, and produce fewer flowers. Full shade is not recommended.

How often should I divide catmint?

Divide every three to four years in early spring when the center of the clump becomes woody and dies out. Discard the dead center and replant vigorous outer sections. Spring division gives plants time to establish before winter.

Is catmint invasive?

Garden catmint (Nepeta x faassenii hybrids) forms clumps and does not run aggressively like culinary mint. Most modern cultivars are sterile and do not self-sow. Species types may volunteer lightly but are easily controlled.

Catmint Delivers Months of Continuous Color

One of the biggest reasons gardeners fall for catmint is the sheer length of its floral display. While many perennials put on a two-week show and call it a year, catmint starts blooming in late spring and keeps going until hard frost. In my zone 6 garden, the first spikes appear in late May. By June, the plants are solid clouds of color. They slow down a bit in the heat of July, but a quick shear brings a fresh flush that carries straight through October.

The Bloom Cycle Explained

Catmint produces flowers on terminal spikes that rise above the foliage. Each spike carries dozens of tiny tubular blossoms in shades of lavender, blue, violet, or white depending on the cultivar. The individual flowers are small, but the mass effect is spectacular. A mature plant can produce hundreds of spikes at once. Because the flowers are sterile in most modern hybrids, the plant puts all its energy into blooming rather than setting seed. This is why the show goes on and on.

Best Cultivars for Extended Bloom

• ‘Walker’s Low’: The 2007 Perennial Plant of the Year. Grows 24 to 30 inches tall and wide. Deep lavender-blue flowers. Despite the name, it is not low growing.
• ‘Cat’s Meow’: More compact at 17 to 20 inches. Dense habit resists flopping. Intense blue flowers.
• ‘Cat’s Pajamas’: Even smaller at 12 to 14 inches. Perfect for front of border or containers. Blooms earlier than most.
• ‘Blue Wonder’: 12 to 15 inches tall. True blue flowers. Excellent heat tolerance.
• ‘Six Hills Giant’: One of the tallest at 36 inches. Looser habit. Great for cottage gardens.
• ‘Junior Walker’: A dwarf version of ‘Walker’s Low’ at 15 to 18 inches. Same flower power in a smaller package.

Simple Trick for Nonstop Flowers

Here is the secret that nurseries do not always tell you. When the first heavy flush finishes in early summer, shear the whole plant back by half. Use hedge shears or even a string trimmer for large plantings. It looks brutal for about a week. Then fresh foliage emerges, followed by a second massive bloom cycle. You can repeat this in late summer for a third round. I do this every year and my neighbors ask what magic fertilizer I use. The answer is just a haircut.

A Pollinator Paradise in Your Backyard

If you care about supporting wildlife, catmint should be at the top of your planting list. The tubular flowers are perfectly shaped for long-tongued bees, bumblebees, and hummingbirds. Butterflies perch on the spikes and sip nectar for hours. On a sunny July afternoon, my catmint patch literally hums. I have counted seven different bee species on a single plant. Honeybees, carpenter bees, mason bees, leafcutter bees, and tiny sweat bees all visit. The nectar flow is consistent because new flowers open daily along the lengthening spikes.

Why Pollinators Love Catmint

Several factors make catmint a pollinator favorite. First, the flower structure. The lower lip of each tubular bloom acts as a landing platform. The upper lip protects the reproductive parts and nectar from rain. Second, the nectar itself is high in sucrose, which many bees prefer. Third, the bloom timing fills a critical gap. Many spring bulbs and early perennials finish by June. Summer annuals have not hit their stride. Catmint bridges this “June gap” when pollinators are desperate for resources.

Creating a Pollinator Corridor

Plant catmint in drifts of three, five, or seven plants rather than singles. Mass plantings are more visible to passing insects and allow them to forage efficiently. Pair catmint with other pollinator plants that bloom at different times. Good companions include salvia, coneflower, bee balm, butterfly weed, and ornamental oregano. Add a shallow water source with pebbles for landing pads. Avoid pesticides entirely. Even organic sprays can harm beneficial insects. Let the catmint do its job as a living buffet.

Hummingbirds and Catmint

Many gardeners are surprised to learn hummingbirds visit catmint. The flowers are not the classic red trumpet shape, but the nectar content is high enough to attract them. I regularly see ruby-throated hummingbirds working my ‘Walker’s Low’ patch at dusk. They move methodically from spike to spike, hovering briefly at each flower. Plant catmint near a seating area or window where you can watch the aerial show. It is better than television.

Thrives on Neglect: The Ultimate Low-Maintenance Perennial

Let us be honest. Most of us want beautiful gardens but have limited time, energy, or water. Catmint delivers maximum impact for minimum input. Once established, which takes one growing season, these plants ask for almost nothing. They tolerate drought, poor soil, heat, humidity, and neglect. I have seen catmint thriving in abandoned lots, hell strips along roads, and gardens where the irrigation failed for weeks. It is the plant equivalent of that friend who shows up looking great after camping for a week.

Drought Tolerance Explained

Catmint develops a deep, fibrous root system that mines moisture from far below the surface. The gray-green leaves are covered in fine hairs that reduce water loss through transpiration. The aromatic oils that give the foliage its scent also help prevent desiccation. In my garden, established catmint gets watered maybe three times all summer, and only during extreme heat waves. New plantings need regular water for the first eight to twelve weeks. After that, they are on their own.

Soil Adaptability

Catmint grows in sand, clay, loam, rocky soil, and even the compacted subsoil left after construction. It prefers neutral to slightly alkaline pH but tolerates a wide range. The only dealbreaker is wet feet. Poor drainage leads to root rot, especially in winter. If your soil is heavy clay, amend with coarse sand or fine gravel at planting time. Plant on a slight mound to encourage runoff. Avoid rich, heavily amended beds. Too much fertility produces floppy, weak growth with fewer flowers. Lean soil makes strong plants.

No Deadheading Required

This is a game changer for busy gardeners. Most long-blooming perennials need regular deadheading to keep flowering. Catmint does not. Because the flowers are sterile, the plant does not receive the hormonal signal to stop blooming after seed set. It just keeps producing new spikes. The spent flowers simply drop off cleanly. You never see ugly brown seed heads. If you want a tidier look, the mid-season shear I mentioned earlier takes care of everything at once.

Natural Pest and Deer Resistance

Gardeners in deer country know the heartbreak of watching expensive plants become midnight snacks. Catmint contains nepetalactone, the same compound that drives cats wild, along with other volatile oils that mammals find distasteful. Deer, rabbits, groundhogs, and voles almost never browse catmint. I have gardened in heavy deer pressure areas for twenty years. My catmint has never been touched, not even in the worst winters when deer eat spruce needles and holly leaves.

Insect Pest Resistance

The aromatic foliage also repels many insect pests. Aphids, spider mites, whiteflies, and flea beetles tend to avoid catmint. I have never seen significant insect damage on any variety. This makes catmint an excellent companion plant for vegetables and roses. Plant a border of catmint around your vegetable garden or interplant with roses. The strong scent masks the smell of desirable crops, confusing pests. Some gardeners report reduced Japanese beetle damage on nearby plants, though this is anecdotal.

Mosquito Repellent Properties

Research from Iowa State University found that nepetalactone is ten times more effective at repelling mosquitoes than DEET. While simply growing catmint will not create a mosquito-free zone, crushing the leaves and rubbing them on skin provides temporary relief. You can also make a simple spray by steeping fresh leaves in boiling water, straining, and adding a splash of witch hazel. Keep a spray bottle by the back door for evening gardening sessions. It smells pleasant and works surprisingly well.

Design Versatility for Every Garden Style

Catmint fits into almost any garden design. Its soft, billowy texture contrasts beautifully with bold foliage plants like hostas, ornamental grasses, and succulents. The cool blue flowers harmonize with almost any color scheme. They look stunning with yellow coreopsis, orange butterfly weed, pink coneflowers, white shasta daisies, and deep purple salvias. The silvery-green foliage provides a neutral backdrop that makes neighboring colors pop.

Border and Edging Superstar

Low-growing varieties like ‘Cat’s Pajamas’ and ‘Blue Wonder’ make perfect edging plants along paths and driveways. They stay compact, tolerate foot traffic better than most perennials, and release their fragrance when brushed. Taller varieties like ‘Walker’s Low’ and ‘Six Hills Giant’ work in the middle of mixed borders. They provide a soft haze that visually connects taller shrubs and shorter perennials. Plant in odd-numbered groups for the most natural look.

Rock Gardens and Slopes

Catmint loves the sharp drainage of rock gardens and slopes. The roots anchor soil on banks, preventing erosion. The cascading habit looks natural spilling over rocks or retaining walls. Pair with sedums, creeping thyme, ice plant, and dwarf conifers for a tapestry effect. On a steep slope in my previous garden, I planted ‘Walker’s Low’ on three-foot centers. Within two years, it formed a solid mat that held the soil and required zero maintenance.

Container Gardening

Dwarf catmint varieties thrive in containers. Use a gritty, well-draining potting mix. Add perlite or coarse sand to standard mix at a 1:3 ratio. Ensure the pot has drainage holes. Water when the top inch of soil feels dry. Fertilize once in spring with slow-release organic fertilizer. Overwinter pots in an unheated garage or bury them in the ground. In spring, divide and repot if the plant is rootbound. Container catmint on a patio brings pollinators right to your outdoor living space.

Cottage Garden Essential

No cottage garden is complete without catmint. Its informal, slightly wild habit fits the aesthetic perfectly. Let it self-sow gently among foxgloves, hollyhocks, and roses. The sterile hybrids will not become weeds, but species types like Nepeta racemosa may volunteer. These seedlings are easy to pull or transplant. In a true cottage garden, a few volunteers are welcome surprises. Catmint also hides the bare legs of roses and covers dying bulb foliage.

Beyond the Garden: Harvesting and Using Catmint

Catmint is not just a pretty face. The leaves and flowers have a long history of herbal and household use. While catnip (Nepeta cataria) is the famous feline intoxicant, garden catmint contains lower concentrations of nepetalactone. About 50 to 70 percent of cats respond to catmint, but the reaction is usually milder. My cats roll on the plants, chew a few leaves, and zone out for twenty minutes. It provides enrichment without the crazy zoomies that catnip induces.

Calming Herbal Tea

Catmint tea has been used for centuries as a mild sedative and digestive aid. The flavor is minty with subtle citrus and earthy notes. It contains no caffeine. To make tea, steep one tablespoon of fresh leaves or one teaspoon of dried leaves in a cup of boiling water for five to seven minutes. Sweeten with honey if desired. Drink before bed for relaxation or after meals for digestion. Pregnant women should avoid medicinal amounts, though culinary use is generally considered safe.

Harvesting and Drying

Harvest stems just as flowers begin to open, when essential oil content peaks. Cut in the morning after dew dries but before the sun gets hot. Bundle small bunches and hang upside down in a dark, airy space. A garage or shed works well. When leaves crumble easily, strip them from stems and store in airtight jars away from light. Properly dried catmint retains potency for a year. You can also freeze fresh leaves in ice cube trays with water for summer iced tea.

Natural Sachets and Potpourri

Dried catmint leaves make excellent sachets for drawers and closets. The scent repels moths and other fabric pests naturally. Combine with lavender, cedar shavings, and a few drops of essential oil for a custom blend. Catmint also adds a lovely note to herbal potpourri. The dried flower spikes retain their color well if dried quickly in a dehydrator or very low oven. They add texture and a subtle blue-gray hue to arrangements.

Cat Toys and Enrichment

If you have cats, grow a patch just for them. Plant Nepeta cataria (true catnip) or a potent catmint variety in a protected spot. Harvest and dry leaves for homemade toys. Sew small fabric pouches, stuff with dried leaves, and stitch closed. Cats go crazy for these. You can also sprinkle dried leaves on scratching posts or cat trees. Rotate toys weekly to maintain novelty. Your cats will thank you, and you will save money on store-bought catnip toys.

Common Mistakes and How to Avoid Them

Even with an easy plant, things can go wrong. Here are the pitfalls I see most often and how to sidestep them.

Planting in Wet Soil

This is the number one killer. Catmint hates wet feet, especially in winter. If your soil stays soggy, plant on a raised berm or in a container. Amend heavy clay with expanded shale, coarse sand, or fine gravel. Do not use fine sand. It creates concrete. Test drainage by digging a hole, filling with water, and timing how long it takes to drain. If it takes more than four hours, improve drainage or choose a different spot.

Over Fertilizing

Rich soil makes weak, floppy catmint with few flowers. Skip the compost, manure, and synthetic fertilizers. If your soil is extremely poor, a light top-dressing of compost in early spring is plenty. I never fertilize my established catmint. The plants are compact, upright, and floriferous. Lean conditions also increase essential oil content, making the foliage more aromatic and pest resistant.

Crowding Plants

Catmint needs air circulation to prevent fungal issues in humid climates. Space plants according to their mature width. ‘Walker’s Low’ needs 30 inches. ‘Cat’s Pajamas’ needs 14 inches. If plants grow together, thin them by removing entire stems at the base. Good airflow reduces powdery mildew risk. In the Southeast, where humidity is high, spacing is critical. I learned this the hard way after losing a beautiful drift to mildew one wet summer.

Skipping the Summer Shear

Without the mid-season cutback, taller varieties can become leggy and flop open in the center. The plant puts energy into maintaining old growth rather than producing fresh flowers. The shear feels drastic but the plant recovers fast. If you forget, do it anyway. Even a late July shear yields a decent fall show. Set a calendar reminder for early July. Your future self will thank you.

Dividing Too Often or Not Enough

Catmint benefits from division every three to four years. The center of old clumps dies out, leaving a donut shape. Spring is the best time, just as new growth emerges. Dig the whole clump, discard the woody center, and replant vigorous outer sections. Water well. Do not divide in fall. The plants need time to establish roots before winter. In zones 3 and 4, spring division is especially important for winter survival.

Choosing the Right Catmint for Your Garden

With so many cultivars available, selection can feel overwhelming. Here is a quick guide to match the plant to your needs.

For Small Spaces and Containers

• ‘Cat’s Pajamas’: 12 to 14 inches. Earliest to bloom. Compact mound.
• ‘Cat’s Meow’: 17 to 20 inches. Dense habit. Intense color.
• ‘Blue Wonder’: 12 to 15 inches. True blue. Heat tolerant.
• ‘Junior Walker’: 15 to 18 inches. Mini ‘Walker’s Low’.

For Maximum Impact in Borders

• ‘Walker’s Low’: 24 to 30 inches. Proven performer. Longest bloom.
• ‘Six Hills Giant’: 36 inches. Loose, romantic habit. Cottage gardens.
• ‘Blue Dragon’: 24 to 30 inches. Larger flowers. Upright stems.

For White Flowers

• ‘Snowflake’: 12 to 14 inches. Pure white. Compact.
• ‘White Wonder’: 18 to 24 inches. Creamy white. Vigorous.

For Pink Flowers

• ‘Pink Cat’: 12 to 18 inches. Soft pink. Long blooming.
• ‘Little Titch’: 8 to 10 inches. Tiny. Pink-lavender. Rock gardens.

For Hot, Humid Climates

• ‘Blue Wonder’: Best heat and humidity tolerance.
• ‘Cat’s Meow’: Bred for Southern performance.
• Nepeta subsessilis varieties: Native to Japan. Handles humidity better than European species.

Companion Planting Strategies

Catmint plays well with others. Its cultural needs match many popular perennials. Here are winning combinations I have used for years.

With Roses

This is the classic pairing. Catmint hides bare rose canes, suppresses weeds, and may deter aphids and Japanese beetles. The blue flowers complement every rose color. Plant catmint 18 inches from rose bases. Varieties like ‘Walker’s Low’ match the scale of shrub roses. Dwarf types work with miniature roses. The combination looks professional with zero effort.

With Ornamental Grasses

The soft mounds of catmint contrast beautifully with vertical grasses. Try pairing with feather reed grass (Calamagrostis), switchgrass (Panicum), or little bluestem (Schizachyrium). The grass provides winter structure after catmint is cut back. In spring, the emerging grass blades hide the catmint’s winter stubble. It is a four-season partnership.

With Spring Bulbs

Plant catmint over daffodils, tulips, and alliums. The catmint foliage emerges just as bulb foliage starts to yellow. It camouflages the dying leaves without smothering the bulbs. The catmint roots occupy a different soil layer than bulbs, so there is no competition. This trick keeps bulb beds looking tidy through the awkward post-bloom period.

With Mediterranean Herbs

Lavender, rosemary, thyme, sage, and oregano share catmint’s love of sun, lean soil, and sharp drainage. Plant them together in a gravel garden or herb bed. The silvery foliage of lavender and catmint creates a cohesive color story. Harvest from all of them for kitchen and craft use. This grouping is also highly fire-resistant, an important consideration in dry climates.

Catmint Through the Seasons

Understanding the annual cycle helps you anticipate maintenance needs and appreciate the plant’s year-round contributions.

Spring Awakening

In early spring, catmint looks like a mound of gray-green fuzz. New shoots emerge from the woody base. This is the time to cut back last year’s dead stems to the ground. Do not pull them. You might damage the crown. Use clean pruners. If you divide, do it now. Apply a thin layer of compost if desired. Water new divisions well. The first flower spikes appear in late May in most zones.

Summer Glory

June and July are peak bloom. The plants are solid color. Pollinators are constant visitors. This is when you take photos and brag to gardening friends. If you shear in early July, the plants look shorn for ten days. Then fresh growth explodes. August brings the second flush. In hot climates, the plants may slow down in August. Do not panic. They will rebound when nights cool.

Fall Finale

September and October often bring the best show of the year. Cooler temperatures intensify the flower color. The foliage looks fresh after the summer shear. Pollinators are frantic, loading up for winter. Hummingbirds visit daily during migration. Leave the spent flowers standing. They provide winter interest and shelter for beneficial insects. The seed heads catch frost beautifully.

Winter Rest

In zones 5 and warmer, catmint is semi-evergreen. The basal foliage stays green all winter. In colder zones, it dies back completely. Either way, leave the plant alone until spring. The dead stems protect the crown from freeze-thaw cycles. They also provide habitat for native bees that nest in hollow stems. If you must tidy, cut stems to six inches rather than ground level. Mulch lightly with straw or shredded leaves in zone 3 and 4.

Troubleshooting Common Issues

Even tough plants have occasional problems. Here is how to diagnose and fix them.

Powdery Mildew

White powdery coating on leaves, usually in late summer. Caused by high humidity and poor air circulation. Prevention: space plants properly, avoid overhead watering, choose resistant varieties like ‘Cat’s Meow’. Treatment: remove affected leaves, spray with milk solution (1 part milk to 9 parts water) weekly, or use potassium bicarbonate fungicide. The plant usually outgrows it after the summer shear.

Root Rot

Wilting despite moist soil, yellowing leaves, plant collapse. Caused by poor drainage or overwatering. Prevention: improve drainage at planting, water deeply but infrequently. Treatment: if caught early, dig plant, trim rotted roots, replant in improved soil. Often fatal. Better to replace with a new plant in a better location.

Flopping Open Center

Stems splay outward, leaving a bare middle. Caused by rich soil, too much shade, or lack of summer shear. Prevention: lean soil, full sun, annual July cutback. Treatment: shear hard after first bloom. Stake with peony rings early in season if needed. Divide old clumps in spring.

Sparse Flowering

Few flower spikes, leggy growth. Caused by too much shade, over-fertilizing, or old woody clump. Prevention: minimum six hours direct sun, no fertilizer, divide every three to four years. Treatment: move to sunnier spot, stop fertilizing, divide in spring.

Cat Damage

Plants flattened, stems broken, foliage shredded. Neighborhood cats treating your garden as a salon. Prevention: plant catnip in a separate “cat corner” away from prized catmint. Use chicken wire cages until plants establish. Sprinkle citrus peels or use motion-activated sprinklers. Most cats lose interest after the initial excitement.

Propagation: Making More Plants for Free

Catmint is ridiculously easy to propagate. You can turn one plant into dozens within a couple of years.

Division

The most reliable method. Do it in early spring. Dig the entire clump. Shake off soil. Pull or cut the clump into sections, each with roots and shoots. Discard the woody center. Replant immediately at the same depth. Water well. Divisions often bloom the same year. I divide my ‘Walker’s Low’ every three years and give the extras to neighbors. It is the gift that keeps giving.

Stem Cuttings

Take four-inch cuttings from non-flowering stems in late spring or early summer. Strip lower leaves. Dip in rooting hormone if desired. Stick in moist perlite or sand. Cover with a plastic bag. Place in bright shade. Roots form in two to three weeks. Pot up and grow on. This works well for increasing specific cultivars that do not come true from seed.

Seed

Species catmint grows easily from seed. Sow indoors six to eight weeks before last frost. Barely cover. Keep moist. Germination in seven to fourteen days at 70 degrees F. Transplant after frost. Hybrids like ‘Walker’s Low’ are sterile or do not come true from seed. If you want identical plants, use division or cuttings. Seed-grown hybrids are variable but often charming.

Catmint in Public Gardens and Landscapes

Professional landscapers and public gardens rely on catmint for good reason. It performs reliably under tough conditions with minimal staff time. The High Line in New York uses catmint extensively in their matrix planting. The Lurie Garden in Chicago features drifts of ‘Walker’s Low’ mixed with salvias and grasses. Municipal plantings along highways and in median strips often include catmint because it tolerates road salt, pollution, and zero irrigation after establishment.

Mass Planting for Impact

If you have space, plant catmint in masses of twenty, fifty, or a hundred plants. The effect is breathtaking. A river of blue flowing through a landscape. Space plants on 18 to 24 inch centers for quick coverage. Use a single cultivar for uniformity. The maintenance is the same as for a few plants. One shear in July covers the whole area. The pollinator activity is incredible. I visited a five-acre catmint planting at a botanical garden. The sound of bees was louder than traffic on the nearby road.

Green Infrastructure

Catmint is increasingly used in rain gardens, bioswales, and green roofs. Its deep roots absorb stormwater. The foliage filters pollutants. It tolerates the wet-dry cycles of rain gardens better than many perennials. On green roofs, the shallow root system and drought tolerance make it ideal. The Chicago City Hall green roof includes catmint. It survives on four inches of growing medium with no irrigation.

Final Thoughts: Why Catmint Deserves a Spot in Your Garden

After two decades of growing catmint in multiple gardens across different zones, I can say without hesitation that it is the closest thing to a perfect perennial. It asks for so little and gives so much. Months of flowers. Clouds of pollinators. Zero pest problems. Deer resistance. Drought tolerance. Herbal uses. Cat entertainment. Design versatility. And that incredible fragrance when you brush past it on a summer evening.

If you are a new gardener, catmint builds confidence. It succeeds where other plants fail. If you are an experienced gardener, catmint solves problems. It covers bare spots, hides ugly legs, knits together plant combinations, and fills the June gap. If you garden for wildlife, catmint is a non-negotiable essential. The sheer volume of pollinator activity it supports is unmatched by almost any other perennial.

Start with one plant. ‘Walker’s Low’ is widely available and foolproof. Plant it in full sun, well-drained soil, and water it for the first season. Then step back. Watch what happens. Take notes. Take photos. Share divisions with friends. Before you know it, you will be the neighbor handing out divisions and saying, “Plant this. Ignore it. Thank me later.” And you will be right.

Your garden deserves catmint. Your pollinators deserve catmint. Your cats deserve catmint. And honestly, you deserve a plant this generous. Go get some. Plant it this week. The bees will find it by tomorrow.

Frequently Asked Questions

What is the difference between catmint and catnip?

Catnip (Nepeta cataria) is a specific species grown primarily for its effect on cats. It has a weedy habit, white flowers, and high nepetalactone content. Catmint refers to ornamental garden hybrids (mainly Nepeta x faassenii) bred for showy flowers, compact growth, and long bloom time. Catmint has lower nepetalactone levels and milder effects on cats.

Can I grow catmint in a container?

Yes, dwarf varieties like ‘Cat’s Pajamas,’ ‘Cat’s Meow,’ and ‘Blue Wonder’ thrive in containers. Use a gritty, well-draining potting mix with added perlite or coarse sand. Ensure the pot has drainage holes. Water when the top inch of soil is dry. Overwinter in an unheated garage or bury the pot in the ground.

Why is my catmint flopping open in the middle?

Flopping is usually caused by rich soil, too much shade, or skipping the mid-season shear. Catmint prefers lean soil and full sun. Shear plants back by half in early July after the first bloom flush. This promotes dense, upright growth and a second heavy flower display.

Does catmint come back every year?

Yes, catmint is a hardy perennial in USDA zones 3 through 8. It dies back to the ground in winter in cold climates but returns reliably each spring. In warmer zones, it may remain semi-evergreen. Leave dead stems standing over winter to protect the crown and provide habitat for beneficial insects.

How do I use catmint for mosquito repellent?

Crush fresh catmint leaves and rub them directly on exposed skin for temporary mosquito relief. For a spray, steep one cup of fresh leaves in two cups of boiling water for 30 minutes. Strain, cool, add two tablespoons of witch hazel, and pour into a spray bottle. Reapply every one to two hours outdoors.

Can catmint be grown from seed?

Species catmint grows easily from seed sown indoors six to eight weeks before the last frost. However, named cultivars like ‘Walker’s Low’ are sterile hybrids and will not come true from seed. For identical plants, propagate by division in early spring or take stem cuttings in late spring.
