About Nepeta

Nepeta, commonly known as catmint, is one of the longest-blooming and easiest-care perennials you can grow in a flower garden. Beloved for its soft lavender-blue flower spikes, silvery-green aromatic foliage, and relaxed billowing habit, nepeta adds months of color and texture to sunny garden beds with very little maintenance.

As a member of the mint family, nepeta is drought tolerant once established and thrives in full sun with well-drained soil. It’s especially popular in cottage gardens, pollinator gardens, and mixed perennial borders because it pairs beautifully with roses, salvia, peonies, alliums, and other classic garden plants.

One of the things I love most about nepeta is how versatile it is in the landscape. It looks just as beautiful spilling over pathways and stone walls as it does softening the edges of formal borders. Plus, pollinators absolutely adore it. Bees, butterflies, and hummingbirds visit the flowers constantly throughout the growing season in my garden.

Another huge bonus? Nepeta blooms for an incredibly long time, especially when sheared back after its first flush of flowers. In my New Jersey garden, it often flowers from late spring well into summer and sometimes beyond with a light trim.

Why Nepeta Earns a Spot in My Garden Every Year

Nepeta is one of those hardworking perennials that quietly does it all. It flowers for months, attracts pollinators nonstop, handles heat and dry conditions with ease, and asks for very little maintenance in return. After growing it in my gardens for decades, it’s become one of those plants I reach for again and again when designing borders and cottage garden beds.

Here’s why I love growing nepeta so much:

• Long Bloom Season: Nepeta flowers for months, especially when trimmed back after its first flush of blooms.
• Low Maintenance: Once established, it tolerates heat, drought, and average soil beautifully with very little care.
• Pollinator Friendly: Bees, butterflies, and hummingbirds constantly visit the flowers in my garden throughout the growing season.
• Deer and Rabbit Resistant: Its aromatic foliage tends to be less appealing to deer and rabbits than many other perennials.
• Beautiful Cottage Garden Plant: Nepeta’s soft billowing habit pairs beautifully with roses, salvia, peonies, alliums, and other cottage garden favorites.
• Versatile in the Landscape: It works beautifully in borders, pollinator gardens, along pathways, and even spilling over retaining walls.
• Fragrant Foliage: The gray-green foliage releases a pleasant minty fragrance when brushed against.
• May Help Deter Mosquitoes: Like other aromatic plants in the mint family, nepeta may help discourage mosquitoes near outdoor spaces.

How to Grow Nepeta

Light Requirements for Nepeta

Nepeta grows best in full sun, where it receives at least 6 hours of direct sunlight daily. Full sun helps plants produce more blooms while maintaining that beautiful compact, billowy shape gardeners love.

That said, nepeta can tolerate light shade, especially in hotter climates. In areas with intense summer heat, a little afternoon protection can actually help plants look fresher longer.

In my own garden, the nepeta planted in full sun blooms far heavier and stays much fuller than the plants growing in shadier beds.

Soil Requirements

Nepeta prefers well-draining soil and generally likes things on the drier side once established. It adapts surprisingly well to sandy, rocky, loamy, and even clay soils as long as drainage is good.

From experience, I can tell you catmint does not love wet feet. I have one garden bed that naturally holds more moisture, and the nepeta there never performs quite as well as the plants growing in my drier borders. They tend to get looser, flop more, and slow down flowering faster too.

Nepeta also tolerates a wide range of soil pH, though it grows best in slightly acidic to neutral soil.

Planting Nepeta

Plant nepeta in spring or fall in a sunny location with good air circulation.

To plant:

• Dig a hole about twice the width of the root ball
• Amend the soil with compost if needed
• Plant at the same depth it was growing in the container
• Backfill with soil and water thoroughly

Depending on the variety, space plants about 12-24 inches apart. Always check the plant tag for mature sizing recommendations because some varieties stay much more compact than others.

One of my favorite ways to use nepeta is near pathways and garden borders where the soft foliage can spill naturally onto the walkway. It creates that relaxed cottage garden look I love so much.

Watering Nepeta

Newly planted nepeta should be watered regularly while it establishes roots. But once established, it becomes impressively drought tolerant and typically needs very little supplemental watering.

In my New Jersey zone 6b garden, I usually let nature handle most of the watering and only step in during prolonged periods of extreme heat or drought. Honestly, nepeta performs better for me when I leave it alone a bit instead of fussing over it too much.

A few watering tips:

• Water at the base of the plant to help prevent disease
• Water in the morning whenever possible
• Allow the soil to dry slightly between waterings

Nepeta Maintenance Tips

Nepeta is one of the easiest perennials I grow, but a little maintenance helps keep plants looking fresh and blooming longer.

Fertilizing

In general, nepeta does not require fertilizer. In fact, overly rich soil can sometimes lead to floppy growth. I focus more on improving soil naturally with compost and organic matter instead.

Mulching

Apply a light layer of mulch around plants to help suppress weeds and regulate soil moisture, but avoid piling mulch directly against the crown.

Pruning and Deadheading

After the first major flush of blooms fades, shear plants back by about one-third. This encourages fresh foliage and often another beautiful round of flowers later in the season.

I rarely deadhead individual flowers. Instead, I give the whole plant one big haircut after blooming, and it responds beautifully every time.

Dividing Nepeta

Divide nepeta every few years to maintain vigor and prevent overcrowding. If you’ve never divided perennials before, I share my simple step-by-step process for dividing perennials here.

Growing Nepeta in Pots

Nepeta grows beautifully in containers and is a great option for patios, balconies, and outdoor seating areas where you can enjoy both the long blooms and fragrant foliage up close. I especially love growing catmint near seating spaces because it’s often considered one of the plants that may help deter mosquitoes and flies outdoors.

When growing nepeta in containers long term, drainage is everything. Choose a pot with drainage holes and use a high-quality well-draining potting mix. Since containers dry out faster than garden beds, potted plants typically need more frequent watering during hot summer weather.

One thing I’ve learned from experience is that nepeta usually performs best in containers for a year or two before it benefits from refreshing. At that point, I either:

• plant it in the ground, or
• repot it with fresh potting soil

If repotting, gently loosen and remove some of the old soil around the roots before replanting. You can reuse the same container or size up slightly depending on how large the plant has become.

For gardeners in colder climates, overwintering perennial containers can be tricky. If you want nepeta to survive outdoors year-round in pots, choose varieties hardy at least two zones colder than your growing zone and use durable all-weather planters that can handle freeze-thaw cycles.

Dividing Nepeta Plants

Nepeta is one of the easiest perennials to divide, which is one more reason I love growing it so much. While catmint can technically be propagated from seed or cuttings, I almost always divide established plants instead because it’s faster, easier, and part of regular garden maintenance anyway.

Honestly, I’d rather save my seed-starting space for flowers like zinnias, snapdragons, and calendula that aren’t always easy to find at local nurseries. Nepeta varieties are widely available, so division simply makes the most sense for me.

I usually divide nepeta in early spring or fall every few years when plants start getting crowded or less vigorous.

A few quick tips:

• Choose a cool or overcast day if possible
• Water plants well beforehand or divide after rain when soil is easier to work
• Dig around the outer edge of the clump first before lifting
• Use a sharp spade or garden knife to separate healthy sections
• Replant divisions at the same depth and water thoroughly

Fresh divisions establish quickly and often look even better the following growing season.

Favorite Nepeta Varieties

I’ve grown several different nepeta varieties over the years, and honestly, it’s hard to pick a favorite because they each bring something a little different to the garden. Some stay compact and tidy while others create those big soft billowing mounds that cottage gardens are known for.

Here are a few of my favorite varieties to grow:

Walker’s Low

One of the most popular nepeta varieties for good reason. Despite the name, it isn’t actually low growing. It forms large graceful mounds covered in lavender-blue flowers for months. This is one of my favorite varieties for softening pathways and mixing with roses.

Six Hills Giant

This variety grows larger and looser than many other catmints, creating that relaxed cottage garden look. The flowers are slightly lighter in color, and the plants can get quite wide when happy.

Cat’s Meow

One of the tidiest and most upright varieties I grow. It holds its shape beautifully without flopping and blooms heavily from late spring into summer.

Blue Wonder

A more compact variety with deep blue-purple flowers and a dense habit that works especially well near the front of garden borders.

Purrsian Blue

This newer variety has slightly softer blue flowers and a rounded growth habit. I’ve found it flowers heavily and stays looking fresh for a long time during the growing season.

Cat’s Pajamas

A compact nepeta variety that blooms earlier than many others and flowers nearly from the soil line to the tips of the stems. Great for smaller gardens and border edges.

Summer Magic

A beautiful long-blooming variety with soft lavender-blue flowers and excellent heat tolerance. It blends beautifully into mixed perennial plantings.

What to Plant With Nepeta

One of the reasons I grow so much nepeta is how effortlessly it blends with other perennials in the garden. The soft lavender-blue flowers and billowing habit help soften stronger shapes while tying color palettes together beautifully.

Some of my favorite plants to pair with nepeta include:

Roses

Nepeta is classic planted alongside roses because it softens the structure of rose bushes while helping create that romantic cottage garden feel. To learn more about how I grow and care for roses, please visit the following guides:

Both plants thrive in sunny, well-draining conditions and pair beautifully in drought-tolerant garden designs. To learn more about how I grow lavender, please visit my complete guide to growing lavender here.

Common Pest and Disease Problems

Nepeta is generally one of the easiest and most trouble-free perennials I grow. In nearly 30 years of gardening, I’ve found it to be remarkably resilient compared to many other flowering plants in my borders. Most problems usually come down to overly wet conditions, poor air circulation, or plants growing in more shade than they prefer.

Here are the most common issues you may occasionally see:

Root Rot

Poor drainage is probably the biggest issue nepeta faces. Like many Mediterranean-style perennials, catmint prefers drier conditions and can struggle in heavy or consistently wet soil.

In my own garden, I’ve noticed nepeta starts declining quickly in beds that hold too much moisture. The plants become floppy, growth weakens, and the foliage can start looking stressed or discolored. When this happens, I usually dig and relocate them to a drier area where they recover much better.

Powdery Mildew

Nepeta can occasionally develop powdery mildew, especially in crowded plantings with poor airflow or periods of high humidity. You’ll notice a white or gray powdery coating on the leaves and stems.

Fortunately, I rarely see severe powdery mildew on nepeta in my garden compared to plants like bee balm or phlox. Giving plants enough spacing, avoiding overhead watering, and growing them in full sun helps prevent most issues.

Floppy Growth

While technically not a disease, floppy nepeta is one of the most common complaints gardeners have.

This usually happens when:

• plants receive too much shade
• soil is overly rich
• plants are overwatered
• growth becomes too heavy after flowering

I’ve found nepeta stays much fuller and more upright in full sun and average soil. Shearing plants back after the first flush of blooms also helps refresh growth and keeps plants looking tidier for the rest of the season.

Building a Lower-Maintenance Garden With Nepeta That Gets Better Every Year

One of the things I love most about nepeta is that it proves beautiful gardens do not have to be high maintenance to feel full, layered, and colorful. Plants like this are exactly what shifted my gardening style over the years away from constant upkeep and toward choosing dependable perennials that thrive with less work.

That whole mindset is really the foundation of my book, The Bricks ‘n Blooms Guide to a Beautiful and Easy-Care Flower Garden. If you’ve ever felt overwhelmed trying to figure out what to plant, how to combine it, or why some plants thrive while others struggle, this book walks you through my real-life approach to creating a beautiful flower garden that actually fits your lifestyle.

And nepeta is also one of those plants that taught me the value of tracking what works in the garden year after year. I’ve learned where it blooms best, which beds stay too wet for it, when I like to shear it back, and which varieties perform the strongest in my New Jersey garden because I keep notes as I garden.

That’s exactly why I created The Bricks ‘n Blooms Beautiful and Easy-Care Flower Garden Planner. It’s not just a pretty notebook. It’s the system I use to track plant performance, garden layouts, bloom timing, maintenance tasks, and seasonal changes so my garden keeps improving instead of starting from scratch every year.

Final Thoughts on Growing Nepeta

After growing nepeta in my gardens for nearly 30 years, it’s still one of the first perennials I recommend to gardeners who want reliable color without constant maintenance. Few plants work as hard in the garden while asking for so little in return.

I’ve grown it everywhere from formal rose beds to relaxed cottage garden borders, and it consistently earns its place season after season. The long bloom time, soft billowing habit, pollinator activity, drought tolerance, and deer resistance make it one of the most versatile perennials I grow.

Honestly, some of my favorite moments in the garden happen when nepeta is in full bloom. Bees cover the flowers nonstop, the foliage spills naturally onto pathways, and the cool lavender-blue tones tie so many different plants together beautifully. It’s one of those plants that helps gardens feel softer, fuller, and more established without requiring endless upkeep.

And the more I garden, the more I appreciate dependable plants like this that thrive in real-world conditions instead of demanding perfect care.
