This lovely dwarf cultivar, which comes brimming with royal blue flowers from late spring to early fall, is the ideal height for edging flower beds and walks or for use as a long-blooming groundcover. the Missouri Botanical Garden chose it as a Plant of Merit because of its exceptional quality and dependability.
Height/Spread:
From late April until the first frost, a stunning display of periwinkle blue flowers encased in dark purple calyces is produced. The second season after planting, will almost double in breadth (to over 2 feet across), swiftly filling in the gaps in your garden.
This cultivar is one of the largest and unquestionably one of the showiest, reaching heights of up to 3 feet and a width of 4 feet. In the middle or back of sunny garden beds, profusions of fragrant two-lipped lavender-blue flowers rise above the heavy gray-green foliage beginning in late spring.
This variety, which offers a contrast to the usual blue and lavender hues, is covered in softly perfumed snow white blossoms from late spring to early fall. forms a tidy, low-growing mound that is ideal for edging a pathway or the front of a border. It also appears stunning when combined with its purple-hued companions.
In typical, well-drained soils with full sun to part shade, this genuine catnip is easily grown. Although catnip can withstand severe droughts, it does like some afternoon shade in hotter southern regions. From late spring through summer, clusters of white blooms with purple spots appear at the ends of stems. Housecats adore its leaves, which have been used for many years as a therapeutic herb. Aphids and squash bugs are just two of the many garden pests that catnip deters. See more details on where this species is thought to be invasive to see how it can become out of control in some locations.
Nepeta spreads, right?
The majority of species can survive in a variety of soil conditions, including rocky and sandy soils. Just make sure the soil has a pH range of 5.0 to 7.5 and is well-draining.
Choose a spot that receives direct sunlight and incorporate approximately an inch of compost there. Plants do tend to be bushier in more fertile soil, yet it is not a must.
It’s important to note that some Nepeta species have a propensity for aggressive spread. Planting on raised beds or containers will help you avoid this.
When planting, water thoroughly. For the first season, supply about an inch of water each week. If it hasn’t rained for a few weeks, established plants are drought resilient and will only occasionally need water.
A effective technique to preserve soil moisture and enhance drainage is to add a few inches of mulch around the base of plants each season, such as shredded bark, leaves, or straw.
Can cats be attracted to my garden by nepeta?
Nepetalactone, a substance found in catnip (Nepeta cataria), is attractive to many cats, including tigers and other wild cats. Cats generally respond by rolling, gnawing, or rubbing against the plant or the leaves. If they see that you have any catnip residue on your shoes, they might even go a bit wild.
While some cats become incredibly lively, others become tense, hostile, or drowsy. They might drool or purr. Only five to fifteen minutes pass between catnip reactions. Despite the possibility of a little stomach upset from consuming a big amount, catnip is “purr-fectly harmless and non-addictive.
It’s also typical if your cat exhibits no interest in catnip. Catnip sensitivity is inherited, and between one-third and fifty percent of cats are completely unaffected by the herb.
Where should I grow catmint?
This perennial flower that thrives in cool climates often features blue trumpet-shaped flower clusters and grey-green leaves with a distinctive mint scent. Even though it’s frequently called catnip, cats don’t find it to be as alluring as the real stuff. However, I’ve seen that if given the chance, our cat will indulge herself. Although the plant can reach a height of 3 feet, it frequently sprawls, creating a grey-green ground cover. In the late spring and early summer, it blooms profusely. In hot temperatures in the middle of the summer, it frequently temporarily stops flowering before starting up again in the early fall, especially if the plant is vigorously trimmed down. Catmint blooms are beloved by butterflies, hummingbirds, and other useful insects.
In our location, catmint is resilient, though certain types may require winter protection in colder climates. Despite the fact that it may be grown from seed, it is considerably simpler to buy plants from a nearby nursery or get divisions from a friend’s garden in the early spring when it first begins to grow. From early spring through early fall, sow. It is simple to divide catmint. Catmint should be planted in full or partial sun in humus-rich, compost-added soil that is well-drained. Plant where it will receive afternoon shade if you’re growing in one of our region’s warmer areas. In the garden, space plants 1 to 2 feet apart.
Water newly planted plants well. They may be resistant of drought once they have grown. To help keep weeds at bay and the soil continuously moist, mulch with bark and spread compost around the base of plants in the spring.
If you aggressively deadhead flowers and prune the plant back by two-thirds after each flush of blooms, you may keep catmint in practically constant bloom from late spring until fall. After a few years, springtime division of the plant will encourage renewed development and result in the production of more plants for friends and other plantings. Catmint doesn’t self-sow because it has few pests and sterile seeds.
The traditional cottage garden plant catmint frequently grows with peonies, roses, coreopsis, and delphiniums. It’s a fantastic filler plant to add color and green foliage between later blooming flowers because of its spreading tendency. It thrives when planted in rock gardens next to walls so that it can cascade over them. It can look a little rangy, so it’s not the best option for more formal settings.
With blue-violet flowers and a neater appearance than other types since it doesn’t spread as much, Walker’s Low is a more recent variation.
White Wonder and “Snowflake” are rare white blooming plants that only reach a height of one foot.
The enormous plant and bright blue flowers of Six Hills Giant are well recognized.
Dark blue flowers on 1 to 2 foot tall stems are produced by Blue Wonder.
Nepeta can it grow in partial shade?
- ‘Walker’s Low’ plants are 30 inches tall and 36 inches wide, with lavender-blue flowers. As a side note, the name is not short because it derives from an Irish garden. It is actually almost as tall as the “Six Hills Giant.” Walker’s Low was chosen by the Perennial Plant Association as their Perennial of the Year for 2007.
Don’t restrict yourself to just these four options if you feel driven to hunt for catmint in your neighborhood garden centers. Numerous other top-notch cultivars are also readily available, including “Dropmore,” “Blue Wonder,” and “Junior Walker,” a scaled-down variety of “Walker’s Low” that stands 16 inches tall.
- Catmint tends to grow wider than tall, so give it lots of room.
- Even while catmint likes direct sunlight, it can also tolerate moderate afternoon shadow.
- Water new plants or transplants until they can survive on their own. Following that, established plants can withstand heat and drought.
- Never fertilize it again. Catmint prefers well-drained, somewhat fertile soil. In fact, a plant may flip over or split in half if the soil is excessively rich. In that case, trim the plant back to make it look neat. Compost added in the spring or fall will provide the plant the nutrients it needs to thrive.
- After the first blooming flush of the plants has finished, shear them back by a third or more. The plants will be more orderly, their size will be limited, and this will encourage a second rush of blossoms later in the summer. The plant will still bloom often and maintain its lovely appearance during the stifling summer months even without being sheared.
- Over the winter, keep any dead foliage in place to help protect the crown. Wait till the beginning of spring to trim it.
- Divide catmint every three to four years, preferably in the spring or early fall, to maintain it healthy. During the first growing season, until the plants take root, keep it well-watered.
- Catmint varieties can grow to be quite huge. Pinch the plant back in the spring after it has grown a few inches tall to encourage a bushier growth habit if you wish to limit the plant’s total size.
- Cut a vertical chunk off of an established clump of catmint in the spring to reproduce it. Make sure the division has a strong root system and a number of new shoots. Till the plant takes root, keep it well-watered.
- Cuttings can also be used to spread catmint. Before flower buds grow in the spring, clip healthy shoots at a length of three inches. The cuttings should be placed in a moist medium, such as sand or a peat-perlite mixture. Within two to three weeks, they should start to root.
- Catmint is typically unaffected by either pests or illnesses. The only issue that can occasionally arise is leaf spot. There is no consensus that the severity of this fungus illness justifies control measures.
- Experience has taught me that some cats are drawn to catmint. If you’re worried about this, cover newly planted or transplanted catmint with chicken wire to stop your cat from consuming it or rolling about in it.
- This plant attracts butterflies and bees like crazy. Additionally, hummingbirds adore it.
- You’ll adore this plant if your garden is plagued by four-legged animals other than cats. Deer, voles, and rabbits are deterred by the foliage’s minty aroma. THIS is a plant that pays for itself, at last!

How can I prevent my cat from ruining my Nepeta?
Nepetas, sometimes known as catmints, are becoming more popular as perennials due to their lengthy flowering season, appealing coloring, and thick growth. There is only one issue: cats!
Cats adore this plant, which is why it’s called catmint. Cats can be attracted to catnip, a nepeta (Nepeta cataria), which is an old feline favorite. They scuff against it, roll about on it, and rub against it. They are drawn to the nepetalactone that injured leaves and stems release. And nepetalactone sensitivity affects around two-thirds of domestic cats.
As catnip (N. cataria) is typically grown for feline amusement and isn’t particularly attractive, this isn’t typically a concern. The other nepetas, however, are decorative trees. You don’t want cats digging them up or scratching them to death. True, they emit a lot less nepetalactone than catnip, but cats may still get them all messed up.
Some roots and leaves will surely be broken or injured while planting, releasing nepetalactone and attracting cats as a result. Therefore, to deter cats, cover newly planted nepetas with some form of barrier (a cut-off gallon milk container, for example). The smell that was unintentionally produced during planting will be gone after 4 or 5 days, and cats won’t be a problem.
If you inadvertently wound or crush your nepeta, it will live a lovely, cat-free life, so keep your cat barrier close by!
Should Nepeta be deadheaded?
Deadheading is beneficial if done frequently during the growth season since it promotes perennials to continue blooming. Nepeta can be pruned back after flowering for a new growth spurt and further display of flowers.
Why does Nepeta entice cats?
The key distinction between catnip and catmint for gardeners who have cats is that only the latter will stimulate cats and make them go wild. Nepetalactone is a chemical found in catnip plants. Cats adore this, which is what makes them want to eat the leaves that make them feel happy. Nepetalactone is okay to have about the house because it also deters insects.
According to some reports, certain cats are interested in catmint. If they do, they’re more inclined to roll around in the leaves rather than consume them like cats do with catnip. Catnip is the best option if you’re wanting to cultivate a plant only for your cats’ amusement, while catmint is a nicer perennial with more consistent blossoms.
Catmint vs. Catnip
Which is better, catnip or catmint? Plant common names can be confusing, especially when they sound so similar. Nepeta cataria, a widespread member of the mint family with white flowers that can be found all over the United States, particularly in disturbed areas, is known as catnip. These low-growing plants are a favorite among cats, and dried leaf cat toys are known to drive cats crazy.
On the other hand, catmint, another member of the mint family, is a stunning decorative plant that is hardy and flexible but is not as well-liked by domestic cats.
Walker’s Low Catmint: Nearly Perfect
Nepeta faassenii, often known as Walker’s Low catmint, has long served as the benchmark catmint in western gardens. In May, mounds of glistening periwinkle blue flowers begin to open, continuing for one to two months.
The blooms are a haven for hummingbirds, moths, butterflies, and bees, but deer and rabbits seem to avoid them. Catmints are nearly ideal plants since they can withstand drought, bloom for a long time, and withstand our harsh weather.
That is, almost flawless, barring two aspects. The weight of the blooms eventually causes the stalks to drop, opening and flattening the plant’s core, which causes all catmints to flop out a little after blooming.
The majority of catmints found at garden centers are fertile, which means that after blooming and receiving pollinator fertilization, they set viable seeds that disperse throughout the garden and result in an abundance of seedlings growing. Free seedlings are occasionally appreciated (especially those of such a lovely plant), but they are frequently an annoyance.
One more warning: Walker’s Low isn’t actually that “low.” Walker’s Low has a height range of 24 to 30 inches, which is quite low compared to Six Hills Giant, the previous benchmark for garden catmints, which reaches a height of 3 feet. Walker’s Low is actually not as low as its name suggests considering how little it is!
Little Trudy: Compact and Not a Spreader
Try Little Trudy catmint if you want a catmint with a neater appearance, one that stays compact and is more suited for small gardens, or one that won’t seed itself.
Before being released by Plant Select in 2008, Little Trudy was found at Little Valley Wholesale Nursery in Brighton, Colorado, and tested at Colorado State University and the Denver Botanic Gardens. It begins to bloom in the late spring and will continue to softly blossom all summer long. When crushed, the tiny, grey-green leaves release a pleasant scent.
Wildlife benefits: Pollinators such as moths, bees, butterflies, and hummingbirds are drawn to stalks of small, purple-blue blooms.
Growing advice: If desired, prune back the first heavy flush of blooms; a second full flush will occur later in the summer.
