Cat’s Pajamas Catmint Plant

Cat’s Pajamas catmint is a dwarf, floriferous perennial that blooms from early summer through fall with vibrant indigo-blue flowers. This low-maintenance, deer-resistant plant attracts bees and butterflies while staying compact at just 12-14 inches tall, making it ideal for borders, containers, and small garden spaces.

If you have been searching for a perennial that delivers big impact in a small package, let me introduce you to the Cat’s Pajamas catmint plant. This charming little powerhouse has quickly become a favorite among gardeners who want reliable color without the fuss. I remember the first time I planted it in my own front border. I was skeptical that something so compact could really hold its own. By midsummer, it was absolutely buzzing with bees and covered in flowers. It has earned a permanent spot in my garden ever since.

This variety, known botanically as Nepeta ‘Cat’s Pajamas’, is part of the Proven Winners collection. It was bred specifically for its tidy habit and incredible flower power. Unlike some older catmint varieties that can get floppy or sprawl all over their neighbors, this one stays neat and upright. It forms a perfect little mound of aromatic gray-green foliage. Then comes the show. From early summer right up until frost, it pumps out spikes of deep indigo-blue flowers. The calyxes are dark too, so even after the petals drop, the plant still looks colorful. That is a detail I really appreciate.

Getting to Know Cat’s Pajamas Catmint

What Makes This Variety Special

There are quite a few catmints on the market. You have probably seen Nepeta ‘Walker’s Low’ or ‘Cat’s Meow’. Those are great plants, but they get big. ‘Walker’s Low’ can reach three feet tall and wide. That is a lot of real estate in a small bed. The Cat’s Pajamas catmint plant was bred to solve that problem. It tops out around fourteen inches tall and twenty inches wide. That compact size opens up so many possibilities. You can tuck it into the front of a border. You can plant it along a pathway. It thrives in containers on a sunny patio. It even works in rock gardens where space is tight.

The breeding work focused on more than just size. The flower color is a richer, deeper blue than many older varieties. The bloom time is exceptionally long. It starts early, often in June, and keeps going strong through September or even October if you deadhead it. The foliage is dense and clean, resisting the powdery mildew that sometimes plagues catmint in humid climates. And the fragrance? That classic minty, slightly spicy scent is there in full force. Brush past it on a warm day and you will know exactly why cats love it.

Botanical Background and Hardiness

Catmint belongs to the mint family, Lamiaceae. You can tell by the square stems and opposite leaves. The genus Nepeta contains over 250 species, mostly native to Europe, Asia, and Africa. The garden hybrids we grow today are complex crosses selected for ornamental value. Cat’s Pajamas catmint plant is hardy in USDA zones 3 through 8. That covers a huge swath of North America. It handles cold winters with ease. In the deep south, it may struggle with the intense heat and humidity of July and August. Some afternoon shade helps in those regions.

One thing to clarify right away. Catmint is not the same as catnip (Nepeta cataria). Catnip is the one that sends felines into a frenzy. Catmint has a much milder effect on cats. Some cats ignore it completely. Others might rub against it or nibble a leaf. It will not destroy your planting. If you have neighborhood cats that like to nap in garden beds, this plant is tough enough to bounce back.

Planting Your Cat’s Pajamas Catmint Plant

Choosing the Perfect Spot

Sun is the name of the game here. This plant wants full sun. That means at least six hours of direct sunlight per day. Eight hours is even better. In return for that sun, you get the strongest stems, the most flowers, and the best fragrance. If you plant it in too much shade, it will get leggy. The stems will stretch toward the light. Flower production drops off dramatically. The plant becomes prone to flopping. I learned this the hard way when I tried to squeeze one into a spot that only got morning sun. It survived, but it was a sad, floppy thing. I moved it to a sunny raised bed the next spring and it transformed into the star it was meant to be.

Soil drainage is the other non-negotiable. Catmint hates wet feet. Heavy clay soil that stays soggy after rain will rot the roots. If you have clay, amend it generously with compost, coarse sand, or fine gravel before planting. A raised bed works beautifully. A slope works beautifully. A container with good drainage holes works beautifully. The ideal soil is average to lean fertility. You do not need rich, amended soil. In fact, overly rich soil encourages soft, floppy growth. Lean soil produces tougher, more compact plants with better flower color. A slightly alkaline to neutral pH is perfect, but it is not fussy.

When and How to Plant

Spring is the ideal planting time. The soil is warming up. Rain is usually reliable. The plant has a full season to establish roots before winter. Early fall works too, provided you plant at least six weeks before your ground freezes. This gives roots time to anchor. Summer planting is possible but requires diligent watering until established.

Space plants eighteen to twenty inches apart. They will fill in to form a continuous mass if that is your goal. For a more defined specimen look, give them twenty-four inches. Dig a hole twice as wide as the pot and just as deep. Gently loosen the roots if they are circling. Set the plant so the crown sits level with the soil surface. Backfill with native soil. Firm it gently. Water thoroughly to settle the soil and eliminate air pockets. Apply a thin layer of mulch, keeping it away from the crown. Gravel mulch looks great and improves drainage. Shredded bark works too. Avoid piling mulch against the stems.

Container Planting Tips

Cat’s Pajamas catmint plant is a fantastic container plant. Its compact size means it won’t outgrow a pot in one season. Choose a container at least twelve inches wide and deep. Terra cotta, ceramic, or fiberglass all work. Ensure there are drainage holes. Use a high-quality potting mix blended with perlite or pumice for extra drainage. A mix designed for succulents or cacti, amended with a bit of compost, is ideal. Do not use garden soil in pots. It compacts and drains poorly.

Plant at the same depth as it was in the nursery pot. Water well. Place in full sun. Container plants dry out faster than in-ground plants. Check the soil daily in hot weather. Water when the top inch feels dry. Fertilize lightly. A slow-release balanced fertilizer at planting time is usually enough for the season. Or use a liquid fertilizer at half strength once a month. Stop fertilizing by late July to let the plant harden off for winter. In cold zones, containers need winter protection. Move pots to an unheated garage or bury them in the ground. Or treat as an annual and replace next spring.

Seasonal Care Guide

Spring Awakening

As temperatures warm, you will see new growth emerging from the base. This is the time to clean up last year’s dead stems. Cut them back to about two inches above the ground. Be careful not to damage the new green shoots. If you left the stems standing for winter interest, do this early, before growth gets too tall. A light application of compost around the base is all the feeding needed. Scratch it in gently. Water if spring is dry. New plantings need consistent moisture during their first spring. Established plants are quite drought tolerant.

Watch for the first flower buds forming in late spring. This is a good time to assess the plant’s shape. If it looks a bit uneven, you can give it a very light trim to encourage bushiness. But honestly, this variety is so naturally tidy that it rarely needs shaping. The main spring task is simply enjoying the fresh foliage and anticipating the show to come.

Summer Glory and Deadheading

Early summer brings the first flush of blooms. The plant becomes a magnet for pollinators. Bees of all kinds, butterflies, and even hummingbirds visit constantly. It is a joy to watch. This first flush lasts several weeks. As the flowers fade, the plant can start to look a bit tired. This is where deadheading comes in. Shear the whole plant back by about one-third to one-half. Use hedge shears or sharp pruners. Cut just above a set of leaves. This removes the spent flower spikes and stimulates fresh growth and a second heavy bloom.

I usually do this shearing in mid to late July. It feels brutal at first. You are cutting off green growth. But within two weeks, the plant is a fresh green mound again. Within three to four weeks, it is covered in buds. The second flush often lasts right up until hard frost. If you skip deadheading, you will still get some sporadic rebloom. But the plant looks messier. The second flush is weaker. The energy goes into seed production instead of flowers. For the best show, shear it. It takes five minutes and pays off for months.

Watering in summer? Established plants rarely need supplemental water. In extreme drought, a deep soak every two weeks keeps them happy. Container plants need regular checks. Fertilizing in summer? Not needed. Too much nitrogen reduces flowering and essential oil production. Lean conditions produce the best plants.

Fall and Winter Preparation

As temperatures cool, the fall bloom continues. The foliage often takes on nice purple tints in cool weather. Stop deadheading in early fall. Let the last flowers go to seed. The seed heads provide winter interest and food for birds. Goldfinches love them. Leave the stems standing through winter. They catch snow beautifully. They protect the crown from freeze-thaw cycles. They provide shelter for beneficial insects.

In late winter or early spring, cut the old stems down. That is the only pruning required. No division is necessary for many years. Cat’s Pajamas catmint plant is long-lived and stays vigorous. If the center ever dies out after five or six years, you can divide in early spring. Dig the clump. Cut into sections with a sharp knife or spade. Replant the vigorous outer pieces. Discard the woody center. Water well. But honestly, I have clumps over seven years old that have never needed division.

Designing with Cat’s Pajamas Catmint

Companion Planting Ideas

This plant plays well with others. Its blue flowers and gray-green foliage are incredibly versatile. They cool down hot colors. They harmonize with pastels. They provide a resting point for the eye. For a classic combination, pair it with roses. The catmint hides the bare knees of rose bushes. The blue contrasts beautifully with pink, red, yellow, or white roses. The fragrance mingles delightfully. Both love sun and good drainage. It is a match made in garden heaven.

Ornamental grasses are another stellar partner. The fine texture of catmint against the bold blades of grass creates movement and contrast. Try it with Pennisetum ‘Hameln’, Schizachyrium ‘Standing Ovation’, or Calamagrostis ‘Karl Foerster’. The grass provides winter structure. The catmint provides summer color. For a pollinator paradise, combine it with coneflowers (Echinacea), bee balm (Monarda), black-eyed Susans (Rudbeckia), and salvias. The bloom times overlap. The colors sing together. The insects have a buffet.

In a cottage garden, let it spill over a stone wall or path edge. The soft mound softens hard lines. In a modern landscape, plant it in geometric blocks or rows. The uniform habit creates a clean, architectural look. In a rock garden, tuck it between boulders. The drainage is perfect. The foliage contrasts with stone. For a moon garden, pair the blue flowers with white flowering plants like Gaura ‘Whirling Butterflies’, white Phlox, or Leucanthemum ‘Becky’. The blue reads as purple in low light. It adds depth.

Container Combinations

In pots, Cat’s Pajamas catmint plant is the perfect “filler” in the thriller-filler-spiller formula. Its mounding habit fills the middle beautifully. For a thriller, add a tall grass like Pennisetum ‘Rubrum’ or a spiky Yucca. For spillers, try Calibrachoa, Verbena, or trailing Sedum. A monochromatic blue pot looks stunning. Combine with blue Salvia, blue Angelonia, and blue Lobelia. Add a chartreuse Ipomoea for a pop.

For a hot color pot, pair the cool blue catmint with red Canna, orange Marigold, and yellow Zinnia. The blue tempers the heat. For a pastel pot, combine with pink Petunia, lavender Verbena, and white Bacopa. The gray foliage ties it all together. Remember, container plants need more water and fertilizer. But the catmint is the tough one in the mix. It will handle a missed watering better than its companions.

Landscape Uses Beyond Borders

Think beyond the flower bed. This plant makes a fantastic low hedge along a walkway. Plant them eighteen inches on center. Shear once after the first bloom to keep it tight. It defines the path without blocking views. It releases fragrance when brushed. It handles foot traffic nearby. Use it on a sunny slope for erosion control. The fibrous roots hold soil. The dense foliage slows runoff. It looks great massed on a bank.

Plant it around the base of a mailbox or lamp post. It hides the ugly post. It takes the reflected heat. It stays short enough not to block the mailbox door. Use it in a hellstrip (that tough spot between sidewalk and street). It tolerates salt, heat, drought, and poor soil. It transforms a neglected strip into a pollinator corridor. In a vegetable garden, plant it at the ends of beds. It attracts beneficial insects that prey on pests. It deters some pests with its scent. It adds beauty to the utilitarian space.

Troubleshooting Common Issues

Pests: Rare but Possible

Cat’s Pajamas catmint plant is remarkably pest-free. The aromatic oils that we love repel most insects. Aphids occasionally cluster on tender new growth in spring. A strong blast of water knocks them off. Insecticidal soap works if they persist. Spider mites can appear in hot, dry, dusty conditions. They cause stippled, bronzed leaves. Increase humidity with occasional overhead watering. Horticultural oil controls severe infestations. Whiteflies are rare but possible. Yellow sticky traps help monitor.

The biggest “pest” might be cats. As mentioned, the effect is mild. But some cats really love to roll on it. If a large cat flattens a young plant, it can break stems. A simple cage of chicken wire or a few stakes with twine protects it until it gets woody and tough. Once established, it bounces back from feline attention easily. Deer and rabbits avoid it. The scent and taste are unappealing to them. This is a huge plus in many areas.

Diseases: Prevention is Key

Powdery mildew is the main fungal concern. It appears as white powdery coating on leaves. It thrives in humid conditions with poor air circulation. Prevention is simple. Plant in full sun. Space properly for air flow. Avoid overhead watering, especially in evening. Water at the base. If mildew appears, remove affected leaves. Apply a fungicide labeled for ornamentals. Neem oil or potassium bicarbonate sprays work organically. This variety has good resistance, but no plant is immune in ideal mildew weather.

Root rot is the other risk. It happens in poorly drained soil. The plant wilts even when wet. Leaves yellow and drop. Stems turn black at the base. There is no cure. Prevention is everything. Ensure excellent drainage before planting. Amend heavy soils. Plant high. Use gravel mulch. Do not overwater. If you lose a plant to rot, do not replant catmint in that exact spot without fixing the drainage.

Cultural Problems and Fixes

Floppy, leggy growth? Too much shade, too much water, or too rich soil. Move to more sun. Cut back on water. Stop fertilizing. Shear it back hard in early summer. It will regrow tighter. Few flowers? Usually insufficient sun. Or the plant is very young. First-year plants sometimes bloom lightly. Deadheading stimulates more bloom. Avoid high-nitrogen fertilizer. Yellow leaves? Could be overwatering, poor drainage, or nutrient deficiency. Check soil moisture. If soggy, improve drainage. If dry, water. A soil test reveals deficiencies. Usually, a top-dressing of compost fixes it.

Center die-out after several years? This happens to many perennials. The center gets woody and unproductive. Dig and divide in early spring. Replant vigorous outer sections. This rejuvenates the plant. It is rarely needed with this variety, but good to know. Winter kill? In zones 3-4, a harsh winter with little snow cover can damage plants. Mulch with straw or evergreen boughs after ground freezes. Remove in early spring. Container plants are more vulnerable. Protect them.

Propagation Methods

Division: The Easiest Way

Division is the most reliable way to propagate Cat’s Pajamas catmint plant. It produces mature plants quickly. It rejuvenates older clumps. Do it in early spring as new growth appears. Water the plant well the day before. Dig around the clump, lifting the whole root ball. Shake off excess soil. You will see the crown with multiple growing points. Use a sharp knife, spade, or even an old pruning saw. Cut the clump into sections. Each section needs roots and several shoots. Discard the woody, dead center. Replant divisions immediately at the same depth. Water well. Mulch. Keep moist until established. They often bloom the same year.

You can also divide in early fall, at least six weeks before frost. The process is the same. Fall divisions need winter mulch for protection. Spring is safer in cold climates. Division every four to five years keeps plants vigorous. But as I mentioned, this variety often goes longer without needing it. Divide when you want more plants or when the center declines.

Stem Cuttings: For More Plants

Softwood cuttings root easily in late spring to early summer. Take cuttings from non-flowering shoots. Cut four to six inch pieces. Remove lower leaves. Dip the cut end in rooting hormone powder. Stick in a pot of moist perlite, vermiculite, or a sterile seed-starting mix. Cover with a clear plastic bag or dome to maintain humidity. Place in bright, indirect light. Keep the medium moist. Roots form in two to three weeks. Tug gently to check resistance. Once rooted, transplant to individual pots. Grow on for a few weeks. Harden off. Plant out.

This method is great for producing many plants from one. It is how nurseries do it. Home gardeners can fill a border cheaply. The key is using non-flowering shoots. Flowering shoots root poorly. Take cuttings in the morning when plants are turgid. Keep everything clean to prevent disease.

Growing from Seed: Not True to Type

Cat’s Pajamas catmint plant is a patented cultivar (PPAF). It does not come true from seed. Seedlings will be variable. They might resemble one parent or the other. They will not be the compact, heavy-blooming plant you bought. Also, propagation by seed is prohibited by the plant patent. If you want this exact plant, buy it or propagate vegetatively. If you want to experiment, let it self-sow. You might get interesting seedlings. But they won’t be ‘Cat’s Pajamas’.

Frequently Asked Questions About Cat’s Pajamas Catmint

Is Cat’s Pajamas catmint invasive?

No, Cat’s Pajamas catmint plant is not invasive. It is a sterile hybrid that does not produce viable seed. It spreads slowly by clumping at the base. It will not run through your garden or pop up in unwanted places. It stays where you put it. This is a major advantage over some older catmint varieties that can self-sow aggressively.

Does this plant attract cats like catnip?

It may attract some cats, but the effect is much milder than catnip (Nepeta cataria). Catnip contains high levels of nepetalactone, the compound that triggers the euphoric response. Catmint has much lower levels. Some cats ignore it completely. Others may rub on it or chew a leaf. It rarely causes the wild rolling and drooling associated with catnip. Most gardeners find cat interest to be minimal and not damaging.

Can I grow Cat’s Pajamas catmint in partial shade?

It will survive in partial shade (four to six hours of sun), but it will not thrive. The stems become weak and floppy. Flower production is significantly reduced. The plant is more susceptible to powdery mildew. The foliage loses its dense, compact habit. For the best results, plant in full sun. If you only have partial shade, try Nepeta ‘Blue Dragon’ or Nepeta ‘Kit Cat’, which tolerate a bit more shade.

How often should I water established plants?

Established Cat’s Pajamas catmint plants are very drought tolerant. In most climates, they need no supplemental water once established. In extreme heat and drought, a deep soaking every two to three weeks keeps them looking their best. The key is deep, infrequent watering to encourage deep roots. Frequent shallow watering creates shallow roots and weaker plants. Container plants need regular watering when the top inch of soil is dry.

When should I cut it back for winter?

Do not cut it back in fall. Leave the stems standing through winter. They provide insulation for the crown. They catch snow for extra protection. They add winter interest with their architectural form. They provide shelter for beneficial insects. Cut the dead stems back to about two inches in late winter or early spring, just as new growth emerges at the base. This is the only pruning required.

Why is my catmint not blooming well?

Poor blooming is usually due to insufficient sunlight. This plant needs at least six hours of direct sun, preferably eight. Other causes include: too much nitrogen fertilizer (promotes leaves over flowers), the plant is too young (first-year plants may bloom lightly), lack of deadheading (shearing after first flush stimulates second bloom), or overcrowding (divide if the center is woody). Ensure full sun, lean soil, and shear after the first bloom for maximum flowers.

Conclusion

The Cat’s Pajamas catmint plant truly lives up to its playful name. It is the bee’s knees, the cat’s meow, and the gardener’s dream all rolled into one tidy package. I have grown a lot of perennials over the years. Few deliver this much bang for the buck. Months of vibrant blue flowers. A compact habit that never needs staking. Fragrant foliage that deer ignore but pollinators adore. Drought tolerance that laughs at summer heat. And a versatility that lets it shine in borders, containers, rock gardens, and hellstrips alike.

If you have a sunny spot and well-drained soil, you really cannot go wrong. Plant it once. Enjoy it for years. Shear it once in midsummer for a second act. Cut it back once in spring. That is the entire maintenance schedule. In return, you get a front-row seat to one of the best pollinator shows in the neighborhood. The hum of happy bees becomes the soundtrack of your summer garden. The flash of butterfly wings adds living confetti.

Whether you are a seasoned gardener looking for a reliable workhorse or a beginner wanting a guaranteed success, this plant delivers. It bridges the gap between high performance and low demand. It makes you look like a garden genius with minimal effort. So go ahead. Find a sunny spot. Tuck in a Cat’s Pajamas catmint plant. Sit back. And wait for the compliments. They will come. From the neighbors. From the pollinators. And from your own heart, every time you walk past that mound of indigo blooms. Happy gardening, my friend. You are going to love this one.

Frequently Asked Questions

What is the difference between catmint and catnip?

Catmint (Nepeta x faassenii hybrids) is grown for ornamental value with showy flowers and a tidy habit. Catnip (Nepeta cataria) is a weedy species grown specifically for its high nepetalactone content that affects cats. Catmint has much lower levels of this compound.

How do I prevent my catmint from getting leggy and floppy?

Plant in full sun (6+ hours), avoid rich soil and overwatering, and shear back by half after the first bloom flush. These practices promote dense, upright growth and prevent the weak stems caused by shade or excess fertility.

Will Cat’s Pajamas catmint spread aggressively in my garden?

No, this sterile hybrid does not produce viable seeds and spreads only slowly by expanding its clump at the base. It stays neatly in its allotted space without runners or unwanted seedlings.

What are the best companion plants for Cat’s Pajamas catmint?

Excellent companions include roses, ornamental grasses, coneflowers, black-eyed Susans, salvias, and lavender. All share similar sun and drainage requirements while providing complementary colors and textures.

Can I divide Cat’s Pajamas catmint in the fall?

Yes, early fall division works well if done at least 6 weeks before the ground freezes. Spring division is preferred in colder zones (3-4) to give divisions maximum establishment time before winter.

Why are the leaves on my catmint turning yellow?

Yellow leaves usually indicate overwatering or poor drainage. Catmint prefers dry conditions once established. Check soil moisture and improve drainage if needed. Nutrient deficiency is rare but can be corrected with a light compost top-dressing.
