Nepata, sometimes known as catmint, is a magnificent plant for perennial gardens or mixed beds. It swiftly disperses and can withstand heat, drought, and poor soil. In fact, before long you’ll probably be lending it to others.
Catmint is a relative of catnip but is more flamboyant. It is hardy in USDA plant hardiness zones 3 through 7. When a plant reaches maturity, it develops a rounded, bushy shape with hundreds of tall, lovely stalks. Small, pinnate, gray-green leaves that resemble mint leaves grow on the stalks. Early summer brings on a flood of blooms from the plants, and if you prune them back, they will bloom once again. The most typical color is bluish-purple, however certain variants also exist in pink, white, and even yellow.
Catmint will draw the neighborhood cats, just like catnip does. The plant’s constituents have a slight hallucinogenic or sleepy effect on cats. Even if you don’t have a cat of your own, the plant may have flattened spots where cats have rolled around. Spread a sheet of bird netting over the plants to prevent this frolicking. Catmint not only draws cats, but also bees, moths, and butterflies. The plants are alive with bumblebee and honeybee activity when they are in full bloom. Catmint shouldn’t be grown close to entrances or play areas due to this.
Depending on the kind, catmint can grow to be 12 inches tall or 36 inches tall. Give it plenty of room and divide it every three to four years because it can spread up to three feet in one season. Over the winter, it typically dies back to the ground.
Planting Catmint
Catmint can be grown from seed, divisions from a buddy, or nursery transplants. After the last anticipated frost, sow the seeds outside or start them indoors four to six weeks prior to planting. The most dependable approach to grow this plant is by divisions or transplants because some types are infertile and hybrids may not grow true to seed. Except in regions with extremely hot and dry weather, where it may tolerate some afternoon shadow, catmint blooms best in full sun. It is not necessary for the soil to be especially rich, but it must have good drainage. Prior to planting, incorporate some manure and compost into the soil.
Depending on how big they will be when mature, place the plants 12 to 24 inches apart. For the first four weeks following planting, water the plants often. The plants are drought-tolerant once they are established, but they thrive when watered once a week.
Before new growth appears, fertilize catmints in the spring by spreading 1/4 cup of 10-10-10 fertilizer around the base of the plant. After the first bloom, trim the plants back by at least one-third. If they get out of control over the summer, you can trim them again, but wait until late August to do so.
Catmint Problems and Pests
Catmint shouldn’t cause you any issues as long as the soil drains correctly. But in wet soils, root rot is widespread. In humid, warm environments, catmint can spread. To tame it, give it lots of room and divide it periodically.
Catmint Varieties
The most widely cultivated variety is Faassen’s catmint (Nepeta X faassenii). The height of this plant varies from 12 inches to 24 inches. Because it is sterile, Faassen’s catmint won’t self-sow like other species. Among the varieties are “Kit Kat,” which reaches a height of 2 feet and blooms for a long time, “White Wonder,” which, as its name suggests, has white flowers, and “Six Hills Giant,” which reaches a height of 4 feet and has spikes of 12 inch purple blooms.
Cold-tolerant Siberian catmint (Nepeta sibirica) can reach heights of two to three feet. Compared to Faassen’s catmint, this plant has bigger leaves and bluish-purple blooms.
If your soil is damp, Japanese catmint (Nepeta subsessilis) is the plant for you. On 2 foot tall stalks, it produces lavender to pink blossoms.
The Himalayan native yellow catmint (Nepeta govaniana) flowers in the middle to end of July. If you can’t get it locally, look in garden catalogs and internet resources.
Spreads catmint quickly?
Plants that grow quickly called catmints. They start out in the spring by growing neat tiny piles of tidy new leaves. This spreads widely swiftly when plants start to form their flower buds. Walker’s Low is one of the cultivars that is grown the most frequently. But despite its name, this plant is in no way low-growing. These plants grow rapidly to their full size, which is around 3 feet tall by 3 feet broad. Many of the catmints grow leggy and flop open once their impressive flowering display is over. If this is the case, giving the plants a good cutback will quickly fix the problem. If you’re lucky, this will stimulate a second set of blossoms in addition to a wonderful new flush of growth.
Catmints’ hardiness and tolerance of poor soil conditions are two of their best qualities. Look no farther if you’ve previously struggled with growing anything in dense, dry clay. Catmint can take it and continue to flourish. But it’s crucial to remember that some plants do enjoy some sunshine. Although they can tolerate some shade, they are considerably more likely to flop open. It’s also crucial to keep in mind that many catmint species have a tendency to spread like weeds in gardens. If this worries you, opt for sterile types like “Walker’s Low” that won’t spread and create any further issues. Also recognized for withstanding hard winters is catmint.
How long does it take catmint to grow?
In the fall or very early spring, sow seeds outside. Better stands result from planting in the fall. Under ideal circumstances, seeds germinate in five to ten days, but in colder soil, this time can increase to twenty days. Thin the plants to 18 inches apart when they are 2 to 5 inches tall. After 12 to 15 weeks, you can start picking leaves. If cats frequently visit your garden, use wire netting to protect young plants.
How long does catmint take to bloom?
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.
Does catmint like shade or the sun?
- ‘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!
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 appear 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.
