Catmint Plant at Home Depot

Catmint (Nepeta) is a drought-tolerant perennial that blooms all summer with lavender-blue flowers. Home Depot carries popular varieties like ‘Walker’s Low’ and ‘Cat’s Pajamas’ in spring and fall. This guide covers everything from selection to long-term care.

If you have ever walked through the garden center at Home Depot in April, you have probably seen them. Neat rows of gray-green foliage topped with spikes of purple-blue flowers. The tags say catmint plant or Nepeta. They look tidy. They smell amazing when you brush past them. And the price is usually right.

But buying a healthy catmint plant at Home Depot is only the first step. Getting it to thrive in your yard takes a little know-how. I have planted dozens of these perennials over the years. Some flourished for a decade. Others sulked and died within a season. The difference usually came down to three things: variety choice, planting technique, and that first summer of care. This guide walks through all of it so you can skip the trial and error.

Key Takeaways

• Best varieties at Home Depot: ‘Walker’s Low,’ ‘Cat’s Pajamas,’ ‘Junior Walker,’ and ‘Blue Wonder’ are commonly stocked.
• Shopping season matters: Visit in early spring or fall for the healthiest selection and planting success.
• Sun and drainage are critical: Catmint needs full sun and well-draining soil to thrive long-term.
• Shearing extends blooms: Cut plants back by half after the first flush for a second wave of flowers.
• Deer and rabbit resistant: The aromatic foliage naturally repels common garden pests.
• Great for pollinators: Bees, butterflies, and hummingbirds love the nectar-rich blooms.
• Easy to divide: Mature clumps can be split every 3-4 years to rejuvenate plants and get free new ones.

Quick Answers to Common Questions

When is the best time to buy catmint at Home Depot?

Early spring (March-April) for the best selection, or early fall (September) for fall planting.

Which catmint variety is best for small spaces?

‘Cat’s Pajamas’ stays compact at 12-14 inches tall and wide, perfect for containers and front borders.

How often should I water newly planted catmint?

Water deeply twice a week for the first 6-8 weeks, then reduce to occasional watering once established.

Do I need to deadhead catmint?

No. A single mid-season shear (Chelsea Chop) replaces deadheading and triggers a second heavy bloom.

Will catmint survive winter in zone 4?

Yes, most varieties are hardy to zone 3. ‘Walker’s Low’ has the best cold tolerance.

Understanding Catmint: What You Are Actually Buying

Catmint vs. Catnip: Clearing the Confusion

First, let us clear up the most common mix-up. Catmint (Nepeta x faassenii and hybrids) is not the same as catnip (Nepeta cataria). Both belong to the mint family. Both attract cats. But they play very different roles in the garden.

Catnip is a rangy, weedy-looking plant grown mostly for your feline friends. It reseeds aggressively. It flops. It is not a landscape plant. Catmint, on the other hand, is bred for ornamental value. It forms neat mounds. It blooms for months. It stays where you put it. When you shop for a catmint plant at Home Depot, you are buying the ornamental perennial, not the cat toy.

The Botany Behind the Beauty

Most garden catmints are hybrids of Nepeta racemosa and Nepeta nepetella. This cross gives us the sterile, long-blooming plants we love. Because they do not set viable seed, they pour all their energy into flowers instead of reproduction. That is why a single plant can bloom from May through September with just one mid-season haircut.

The foliage contains nepetalactone, the same compound that drives cats wild. But the concentration is lower than in true catnip. Your neighborhood cats may roll in it occasionally. They will not destroy it.

Top Catmint Varieties You Will Find at Home Depot

Walker’s Low: The Industry Standard

If you buy one catmint plant at Home Depot, it will probably be ‘Walker’s Low.’ This variety won the Perennial Plant of the Year award in 2007 for good reason. It grows 24 to 30 inches tall and wide. The lavender-blue flowers are profuse. The habit is upright but relaxed. It is the most reliable performer across the widest range of climates.

Despite the name, ‘Walker’s Low’ is not a groundcover. The name honors the garden where it was discovered, not its height. Give it room to spread.

Cat’s Pajamas: The Compact Powerhouse

Introduced by Proven Winners, ‘Cat’s Pajamas’ is a newer dwarf variety. It tops out at 12 to 14 inches tall and wide. The flowers are a deeper indigo-blue. The habit is incredibly dense and mounded. This is the one to choose for the front of the border, rock gardens, or containers.

You will often find this in the Proven Winners branded pots at Home Depot. Look for the distinctive white and green container.

Junior Walker: The Middle Ground

‘Junior Walker’ splits the difference. It reaches 15 to 18 inches tall and wide. The flower color matches ‘Walker’s Low’ but on a smaller frame. It is a great choice if you love the classic look but have limited space. It also holds its shape better in rich soil where ‘Walker’s Low’ might flop.

Blue Wonder: The Early Bloomer

‘Blue Wonder’ (Nepeta x faassenii ‘Blue Wonder’) is an older cultivar that still shows up regularly. It grows 12 to 18 inches tall. The flowers are a soft, true blue. It tends to bloom a week or two earlier than the others. The habit can be a little looser, so it benefits from an early-season pinch.

Specialty Finds: Dropmore and Six Hills Giant

Occasionally, Home Depot carries ‘Dropmore’ (taller, 30 inches, violet-blue) or ‘Six Hills Giant’ (the tallest at 36 inches, pale lavender). These are less common but worth grabbing if you see them. ‘Six Hills Giant’ makes a stunning informal hedge.

When and How to Shop for Catmint at Home Depot

Timing Your Visit for the Best Selection

The catmint plant at Home Depot arrives in waves. The first and biggest shipment lands in early spring, usually March or April depending on your zone. This is when you will find the most varieties and the freshest stock. Plants have been hardened off and are ready to go in the ground.

A second, smaller wave often arrives in late summer for fall planting. Selection is narrower, usually just ‘Walker’s Low’ and ‘Cat’s Pajamas.’ But fall planting gives roots a head start before winter.

Avoid buying in the heat of July and August. Plants sitting on hot asphalt for weeks often have fried roots. If you must buy mid-summer, shop early morning and get them in the ground the same day.

Reading the Pot Like a Pro

Do not just grab the first pot you see. Flip it over. You want to see white, fibrous roots reaching the edges of the pot. Brown, mushy roots mean rot. A solid mat of roots circling the bottom means the plant is root-bound. That is fixable but not ideal.

Check the foliage. It should be gray-green and fragrant when crushed. Yellow leaves at the base indicate stress or overwatering. Leggy, stretched stems mean the plant has been fighting for light. Choose a compact, bushy specimen with multiple stems emerging from the crown.

Decoding the Labels

Home Depot uses a few different labeling systems. The standard white tag gives basic info: botanical name, common name, sun needs, height, spacing, and zone. Proven Winners pots have a branded tag with a QR code. Scan it. The website has detailed care guides and design ideas specific to that variety.

Pay attention to the zone rating. Most catmints are hardy in zones 3-8. Some newer varieties push to zone 9. If you are on the edge, ‘Walker’s Low’ has the best cold tolerance.

Planting Your Catmint for Long-Term Success

Site Selection: Sun and Drainage Are Non-Negotiable

This is where most people go wrong. Catmint needs full sun. That means six to eight hours of direct light minimum. In hot southern zones, a little afternoon shade is fine. But in shade, the plants get leggy, flop open, and bloom poorly. They also become magnets for powdery mildew.

Drainage is equally critical. Catmint hates wet feet. Heavy clay soil will kill it faster than drought. If your soil is clay, you have two options: amend heavily with compost and grit, or plant in a raised bed or mound. I have lost count of the catmints I have watched rot in low spots after a rainy week.

Soil Preparation Steps

Dig a hole twice as wide as the pot and just as deep. Mix the excavated soil with compost at a 50/50 ratio. If your soil is heavy, add coarse sand or fine gravel to the mix. Do not use fine sand. It creates concrete.

Do not add fertilizer to the planting hole. Catmint prefers lean soil. Rich soil produces lush foliage at the expense of flowers and structural integrity. The plant will flop. A handful of bone meal is fine if your soil is very poor, but skip the nitrogen.

Planting Technique

Water the plant thoroughly while it is still in the pot. This reduces transplant shock. Gently remove the pot. If roots are circling, tease them apart with your fingers or make three vertical slices with a knife. This sounds harsh. It works.

Place the plant in the hole so the crown sits at soil level. Not deeper. Not shallower. Backfill with your amended soil. Firm gently with your hands. Do not stomp. Water deeply to settle the soil and eliminate air pockets.

Mulch with an inch of shredded bark, pine straw, or gravel. Keep mulch away from the crown. Wet mulch against the stem causes rot. Gravel mulch is ideal for catmint. It reflects heat, improves drainage, and looks great with the gray foliage.

Spacing for Airflow

Space ‘Walker’s Low’ and ‘Six Hills Giant’ 30 inches apart. Space ‘Junior Walker’ and ‘Blue Wonder’ 18 inches apart. Space ‘Cat’s Pajamas’ 14 inches apart. Proper spacing prevents fungal issues and lets each plant develop its natural shape. Crowded catmint is sad catmint.

The First Season: Establishing Your Catmint Plant

Watering Schedule for New Plants

New catmint needs consistent moisture for the first six to eight weeks. Water deeply twice a week if there is no rain. Check the soil with your finger. It should be moist two inches down. Once established, catmint is remarkably drought-tolerant. I water my established plants maybe three times a summer.

Overwatering is the number one killer. If in doubt, wait a day. The foliage will tell you. Slightly wilted leaves in afternoon heat are normal. They perk up by morning. Persistent yellowing means too much water.

The Chelsea Chop: Your Secret Weapon

Around late May or early June, when the first flush of flowers starts to fade, do the Chelsea Chop. Shear the entire plant back by half. Use hedge shears or large scissors. It looks brutal. Do it anyway.

This does three things. It prevents the plant from getting leggy and flopping. It stimulates fresh, compact growth. And it triggers a massive second bloom that lasts into fall. Without this chop, ‘Walker’s Low’ often splits open in the center by July.

If you forget the June chop, you can still do a lighter trim in July. You will get a smaller second flush but better than none.

Fertilizing: Less Is More

I do not fertilize my catmint. Ever. A top-dressing of compost in early spring is plenty. If you must feed, use a slow-release balanced fertilizer at half the recommended rate in early spring. High nitrogen produces weak stems and fewer flowers. The plant literally falls over from its own lushness.

Ongoing Care Through the Seasons

Spring Wake-Up

In early spring, you will see a mound of dead stems from last year. Wait until you see new green growth at the base. Then cut the old stems down to about two inches. Do not pull them out. You might damage the crown. The old stems protect the crown over winter and mark the plant’s location.

This is also the time to divide if the center has died out or the plant has outgrown its space. More on division in a moment.

Summer Maintenance

Deadheading individual spent spikes is not necessary. The Chelsea Chop handles the bulk cleanup. But if you see a few straggly stems, snip them back to a leaf node. Keep an eye out for spider mites in hot, dry weather. They love dusty, stressed plants. A strong blast of water from the hose every few weeks prevents buildup.

Fall Cleanup

Leave the foliage standing through winter. The dried stems and seed heads catch snow, insulate the crown, and provide winter interest. Birds perch on them. Beneficial insects overwinter in the hollow stems. Cut back in early spring instead.

Winter Protection

In zones 3 and 4, a light layer of evergreen boughs or straw after the ground freezes helps prevent freeze-thaw cycles from heaving the crown. Remove it early spring. In zones 5 and up, no extra protection is needed.

Dividing Catmint: Free Plants and Rejuvenation

When to Divide

Every three to four years, the center of a catmint clump dies out. You get a donut shape with growth only on the outer ring. That is your signal. Spring is the best time, just as new growth emerges. Fall works too, but do it at least six weeks before the ground freezes.

How to Divide Successfully

Dig up the entire clump. A sharp spade works better than a fork for dense root balls. Shake off excess soil. You will see the dead center clearly. Use a sharp knife or the spade to cut the living outer ring into sections. Each division needs three to five healthy shoots and a good root mass.

Replant divisions immediately at the same depth. Water well. Treat them like new plants for the first season. You will get three to five new plants from one mature clump. That is a pretty good return on your original catmint plant at Home Depot investment.

Design Ideas: Using Catmint in Your Landscape

The Classic Rose Companion

Catmint and roses are a match made in garden heaven. The soft gray foliage and blue flowers hide the bare legs of rose bushes. The colors complement every rose shade from white to deep red. And catmint plant at Home Depot deep crimson. Plant catmint 18 inches from the rose base in a gentle arc.

Pollinator Highway

Plant a drift of ‘Walker’s Low’ along a sunny path or driveway. The bees will thank you. I count six different bee species on my patch on a July morning. Add coneflowers, bee balm, and salvia for a season-long buffet.

Gravel Garden Star

Catmint thrives in gravel gardens and Mediterranean-style plantings. Pair it with lavender, rosemary, sedum, and ornamental grasses. The gravel mulch keeps the crown dry. The heat reflection intensifies fragrance and bloom.

Container Culture

‘Cat’s Pajamas’ and ‘Junior Walker’ excel in pots. Use a gritty, well-draining mix. One part potting soil, one part coarse sand or perlite, one part compost. Water when the top inch is dry. Fertilize once in spring with slow-release. Overwinter pots in an unheated garage in zones 5 and below.

Edging and Borders

A row of ‘Cat’s Pajamas’ along a front walkway creates a tidy, fragrant edge. It handles light foot traffic. The scent releases when brushed. Kids love it. So do the neighbors’ cats.

Troubleshooting Common Catmint Problems

Floppy, Leggy Growth

Cause: Too much shade, too much water, too much fertilizer, or missed Chelsea Chop. Fix: Move to full sun. Cut back water. Stop fertilizing. Do the chop next June.

Yellow Leaves, Especially at Base

Cause: Overwatering or poor drainage. Fix: Check soil moisture. Improve drainage if needed. Stop watering until top two inches are dry.

Powdery Mildew

Cause: Humid conditions, poor airflow, overhead watering. Fix: Thin crowded plants. Water at base only. Apply neem oil or potassium bicarbonate spray early. Resistant varieties like ‘Cat’s Pajamas’ rarely get it.

Spider Mites

Cause: Hot, dry, dusty conditions. Fix: Blast with water weekly. Increase humidity. Insecticidal soap for severe cases.

Center Die-Out

Cause: Age. The plant needs division. Fix: Divide in spring as described above.

No Flowers

Cause: Too much shade or too much nitrogen. Fix: Move to sun. Stop fertilizing.

Buying Catmint Online vs. In-Store at Home Depot

In-Store Advantages

You see exactly what you get. You can check roots, foliage, and structure. You take it home today. No shipping stress. No surprise substitutions. The price is usually lower than online.

Online Advantages

Home Depot’s website often carries varieties not in your local store. ‘Felix,’ ‘Purrsian Blue,’ and ‘Whispurr Pink’ are online exclusives in many regions. You can read customer reviews. You can schedule pickup or delivery.

My Strategy

I browse online first to see what is available. Then I go to the store. If they have what I want in good condition, I buy it. If not, I order online for store pickup. Best of both worlds.

Companion Plants That Love the Same Conditions

Perennial Partners

• Echinacea (coneflower) – taller, later bloom extends the show
• Perovskia (Russian sage) – airy lavender clouds behind catmint mounds
• Achillea (yarrow) – flat flower heads add shape contrast
• Sedum ‘Autumn Joy’ – succulent foliage, fall color, same tough nature

Grass Companions

• Pennisetum alopecuroides (fountain grass) – soft plumes echo catmint spikes
• Schizachyrium scoparium (little bluestem) – upright blue-green blades, fall color
• Calamagrostis ‘Karl Foerster’ – vertical accent, early plumes

Shrub Backdrops

• Spiraea japonica cultivars – pink flowers, compact habit
• Weigela – spring flowers, some rebloom, hummingbird magnet
• Caryopteris (bluebeard) – late summer blue flowers, same pollinator appeal

Catmint for Specific Garden Challenges

Hell Strips and Curbside Plantings

The area between sidewalk and street is brutal. Heat. Salt. Compaction. Dog traffic. Catmint handles it all. ‘Walker’s Low’ and ‘Junior Walker’ are tough enough. Plant them 18 inches apart in a staggered row. They will knit together into a low hedge that looks good all summer with zero care after establishment.

Slopes and Erosion Control

Catmint’s fibrous root system holds soil on gentle slopes. Plant in drifts of 5-7 plants spaced 24 inches apart. The roots interlock. The foliage slows runoff. It is not a substitute for deep-rooted natives on steep banks, but for moderate slopes, it works beautifully.

Deer and Rabbit Pressure

If Bambi and Thumper treat your garden as a salad bar, catmint is your friend. The aromatic oils repel them. I have watched deer walk right past catmint to eat the hostas behind it. No plant is 100% proof, but catmint is as close as it gets.

Fire-Wise Landscaping

In fire-prone areas, catmint is a recommended plant. It has low fuel volume, high moisture content in leaves, and does not accumulate dead material. Keep it watered and trimmed. Space it away from structures per local guidelines.

Frequently Asked Questions About Catmint at Home Depot

Does Home Depot sell catmint year-round?

No. Catmint is a seasonal item. Most stores stock it from March through June and again in September through October. Winter and mid-summer availability is rare. Check the website or call ahead.

What is the price range for catmint at Home Depot?

Quart pots (4.5 inches) run $5-7. Gallon pots run $10-14. Proven Winners branded quarts are $7-9. Prices vary by region. Spring promotions often include multi-pack discounts.

Can I return a catmint plant if it dies?

Home Depot has a one-year guarantee on perennials. Keep your receipt. Bring the dead plant (or photos) and the tag. They will refund or exchange. This policy is a great reason to buy there instead of a no-return online nursery.

Is catmint invasive?

Ornamental catmint hybrids are sterile. They do not reseed. They spread slowly by clump expansion only. They are not invasive. True catnip (Nepeta cataria) can be aggressive. Make sure you are buying the hybrid.

Will catmint survive in a pot year-round?

In zones 6 and up, yes, with a large pot (14+ inches) and winter protection. In zones 5 and below, the roots freeze solid. Move pots to an unheated garage or sink them in the ground for winter.

How long does a catmint plant live?

With division every 3-4 years, a catmint clump can live indefinitely. Individual undivided plants typically decline after 5-7 years as the center dies out. Division resets the clock.

Conclusion: Your Catmint Journey Starts Today

Walking out of Home Depot with a cart full of catmint is one of the best gardening feelings. You are buying months of color. Years of pollinator visits. A plant that asks for little and gives abundantly. The key is matching the variety to your space, planting it in sun and drainage, and doing that June chop.

Start with one ‘Walker’s Low’ if you have room. Start with ‘Cat’s Pajamas’ if you don’t. Plant it this weekend. Water it for two months. Chop it in June. Watch it bloom until frost. Then divide it in three years and give the extras to a neighbor. That is how gardens grow. That is how gardeners are made.

Your catmint plant at Home Depot is waiting. Go get it.

Frequently Asked Questions

What is the difference between catmint and catnip?

Catmint (Nepeta x faassenii) is an ornamental perennial with sterile flowers that bloom all summer. Catnip (Nepeta cataria) is a weedy plant grown for cats that reseeds aggressively. Catmint forms neat mounds; catnip flops and spreads.

Does Home Depot carry catmint in gallon pots?

Yes, Home Depot typically carries catmint in both quart (4.5-inch) and gallon sizes during spring and fall seasons. Gallon pots cost $10-14 and establish faster.

Can I plant catmint in clay soil?

Only if you amend it heavily with compost and grit, or plant in a raised mound. Catmint requires excellent drainage and will rot in unamended clay, especially during wet winters.

Why is my catmint flopping open in the middle?

This usually means too much shade, too much water, too much fertilizer, or a missed June shear. Move to full sun, reduce watering, stop fertilizing, and do the Chelsea Chop next season.

Is catmint safe for pets?

Catmint is non-toxic to dogs and cats. Cats may roll in it or chew it, but the nepetalactone concentration is much lower than in catnip. It will not harm them.

How do I propagate catmint from my existing plant?

Divide mature clumps in early spring every 3-4 years. Dig up the plant, cut the living outer ring into sections with 3-5 shoots each, and replant immediately. This rejuvenates the plant and gives you free new plants.
