Nepeta is a dependable perennial that grows regularly year after year. It is extremely hardy and tolerant of all environmental factors. When the growing circumstances are unsuitable for lavender, catmint can be used as a viable substitute, creating clouds of light blue and mauve in a garden. Nepeta is beneficial for growing in more challenging sections of the garden since it tolerates a wide range of growth circumstances, such as partial shade, dry weather, and drought zones.
While Lavender cannot survive in wetter conditions, Catmint can withstand them; Lavender needs considerably drier conditions, especially in the winter. As a Mediterranean plant, lavender will struggle on heavier, wetter ground. In contrast to catmint, which can grow practically everywhere, it needs to be dry, in well-drained soil, and in the sun. Nepeta is less picky about where it grows because it is native to many different settings. Catmint can thrive in full or partial sunlight, as well as in damp or dry soil. It can practically be grown everywhere and is incredibly tough. It will only not tolerate really soggy terrain. It has a long flowering period and occasionally produces a second flush of flowers if you cut it down.
Nepeta is quite simple to establish once it is planted. The added benefit is that pollinators and bees find it incredibly alluring. On a warm day, a clump will be buzzing with the sound of bees as you pass it. It is a plant that grows well in practically any environment and doesn’t require feeding, which can cause it to become lanky. As its name implies, it is appealing to creatures other than bees. Insert a few sticks to prevent cats from rolling on your Nepeta if you don’t like cats and don’t want that to happen. The sticks will blend in with the plant growth and will be undetectable to cats. If you enjoy cats, you might just want to stand by and observe how crazy they become when they see cat mint, running after it and rolling around.
Can catmint still be planted now?
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.
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.
Can catmint be grown easily?
The herb catmint is simple to grow. These plants are appropriate for bulk planting or edging, and they can be used as an insect deterrent close to vegetables, particularly for aphids and Japanese beetles.
Catmint can be grown in normal, well-draining soil in the sun or light shade. They are good plants for dry garden regions since they can withstand both heat and drought. The two main ways to cultivate catmint are from seed or through division.
When should catmint be planted?
The perennial herb genus Nepeta, which also includes catnip, is known as catmint (Nepeta cataria). They are very pest- and problem-free plants that are incredibly simple to grow. Nepeta has beautiful, lacy-looking gray-green leaves that is mildly fragrant. Early in the summer, its swaying leaves is crowned with spikes of flowers, which continue to bloom all season. White, pink, or lavender-blue flowers are all possible.
The majority of catmint species have a slightly expansive growth habit, which makes them great plants for running down paths and border planting spaces. There are a few tall-growing types with a more upright habit, including “Six Hills Giant,” though. Catmint is resistant to deer, like many other plants with fragrant gray foliage. It spreads swiftly and may be planted from spring to early fall in most regions.
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.
Can catmint endure the winter?
Catnip has a good level of cold tolerance and thrives in zones 3 through 9. However, growing catnip outside can be problematic in particularly cold winters or in colder areas. It might be important to offer catnip plants some protection and additional care throughout the winter if you want them to return healthy and productively each spring. This is crucial if you reside in the cooler, northern regions of its growing region.
Should I reduce catmint throughout the winter?
In many places, catmint dies back with the frost, and the dead growth needs to be removed in order to make room for the spring’s new, fresh foliage. Depending on the climate where you are, there are different times to do this. It is preferable to wait until the spring thaw to prune catmint in regions with long, hard winters since the dead growth can act as insulation from the cold.
When a plant has gone dormant or has died back due to the cold in a milder region, it is recommended to cut the entire plant back in the fall. Because division will occur with the winter pruning, keep an eye out during the growth season for indications that the plant needs to be divided, such as less blooming.
Use precise pruning shears to cut the entire plant back to the ground, then get rid of the stems. Using a sharp spade, divide the root ball into numerous pieces, each with an equal number of roots and stems, if the plant has to be divided. Place the divisions in a bed with wet, quick-draining soil that is sunny or lightly shaded. Larger catmint kinds, like Six Hills Giant (Nepeta x “Six Hills Giant”), should be planted 3 feet apart, while more common varieties should be planted 1 1/2 to 2 feet apart.
From Seed
Four to eight weeks prior to the last frost date, seeds can be started inside. Seeds should be barely covered in potting mix when placed in three- or four-inch pots.
Maintain moisture for two to three weeks until seedlings appear, and then place the pots in bright light until they have at least two sets of genuine leaves.
Additionally, you can directly plant seeds outside before the first fall frost or in the spring following the last frost.
By chilling stratifying seeds in the freezer for a whole night and then soaking them in water for 12 to 24 hours before planting, you can increase germination.
Garden soil and an inch of organic matter should be prepared for a garden bed or container. Since light promotes germination in these plants, scatter the seeds on top, just covering them.
For two to three weeks, until sprouts grow, lightly water the plant and keep moist. Seedlings should be spaced around 18 inches apart.
Not all nepeta species can be started from seed, which should be noted. Some plants, like Faassen’s catmint, can only be multiplied through division or from cuttings since they are sterile. Fortunately, doing this is simple.
By Division
Although it’s ideal to avoid dividing plants in the heat of the summer, if you have established plants available, divisions are likely the simplest and fastest technique of propagating new plants. These can be taken at any time during the growth season.
Locate a portion of an established plant with a strong, mature root system, cut it off from the rest of the plant using a garden spade, and carefully dig it up.
The entire plant can alternatively be dug up, divided into pieces, and then each piece is planted separately in the garden or in a container.
Does catmint appeal to hummingbirds?
Catmint grows easily, blooms for a long time, can withstand heat, and is pest- and deer-resistant. Shear off the spent blooms and approximately a third of the stem for a second round once the hummingbird flowers have faded. Why we adore it: Siberian catmint blossoms are particularly beloved by hummingbirds (Nepeta sibirica).
Which plants complement catmint well?
There are numerous different plant combinations that are effective with catmint. Consider growing verbena, agastache, lavender, and tufted hairgrass alongside catmint as companion plants.
Plant catmint in a dramatic border with irises and Siberian spurge, or add a splash of color with yarrow to the previously stated rose and catmint combination. For long-lasting blossoms and minimal upkeep, combine yarrow, catmint, agastache, and foxtail lilies.
With catmint, allium, phlox, and white flower lace, spring irises go perfectly. Combine catmint with perennial grasses for a distinct texture. Sneezeweed, catmint, and dahlias all produce magnificent flowers that endure far into the early fall.
Catmint enhances the beauty of coneflower, daylily, and black-eyed susan.
With catmint, the planting combinations are virtually endless. Just keep in mind to group similar plants together. Those that are tolerant of your region and appreciate comparable conditions to catmint, including full sun, average garden soil, and little to no water.
