Is Nepeta Invasive

They believed it would entice cats to prey on rodents hiding about the farm or house. However, current research suggests that catmint may not just be discovered around the foundations of historic European homes and barns. According to a recent USDA study, termites are unlikely to dig tunnels through soil where catmint flourishes. Naturally, a moat made of this plant would prevent these pests from penetrating the wood of a hut or cottage.

Termites, mosquitoes, and cockroaches are all repelled by the same chemical that draws cats. Nepeta cataria, also referred to as common catnip, is a plant that contains it. Nepetalactone, a terpene found in these herbs, has been shown to be several times more effective at repelling insects than harmful DEET. To influence a cat, the plants release oils that must be breathed rather than consumed. This explains why cats are so prone to rolling around in catmint plants. More volatile oils are released from the leaves when it is bruised. Cats can detect airborne odors down to one part per billion.

Not all felines react the same way to these herbs. In fact, roughly 30% of household cats might not even respond to catmint. It’s a hereditary reaction that can vary in intensity from person to person and is inherited. Strangely, until they are at least 3 months old, extremely young kittens rarely react to nepetalactone.

There are a dizzying variety of plants in the genus Nepeta. The large invasive plant known as real catmint is described above. It grows to a height of three feet and bears few white blooms. It usually only appears in herb gardens and has very nothing to recommend it in terms of aesthetics. Due to its hardiness up to Zone 3, it is a fantastic choice for gardens in the north.

Through natural cross-pollination and human breeding, numerous species have been introduced into gardens over time and transformed into new varieties. The outcome is a wide variety of garden-worthy catmints that are much better prospects for your yard than the usual kind. Keep in mind that these immigrants won’t be as resistant to the cold as the species is. The majority, but not all, are sterile, preventing plants from spreading outward in the absence of viable seed. Simply deadhead the flowers after they are spent to stop seed formation in order to completely avoid self sowing.

The Six Hills Giant, which stands 3 feet tall, is the most impressive version. Late in the summer, foot-long spikes of dark violet blooms appear on lush, spherical plants. It is generally accessible and a superb option for novice growers.

Nepeta racemosa “Walker’s Low,” which has a shorter size, is an excellent edging plant. A gentle carpet of blue fills up the front of a border. It only grows to a height of 18 inches but produces dense clusters of vividly blue flower spikes. Walkers Low and Six Hills are resilient to Zone 5.

Catmints typically grow best in sandy, well-drained soils, although they will grow almost anywhere that isn’t moist. Late in the growing season, they can become rangy, and regular trimming is beneficial to prevent the taller forms from flopping in the rain.

Today, catmint merits another look as a natural pest deterrent for eco-friendly dwellings. wherever there is a chance of infestation, plant. Kittie won’t overdose, though, as cats all seem to have a sense of proportion.

Nepeta spreads how?

Nepeta comes in several hundred different species, in addition to numerous other selections (cultivars) that have been chosen for better garden performance. However, I advise using caution when getting catmint plants for your yard. I strongly advise staying away from any Nepeta that is grown from seed, and only planting sterile hybrids. The catmints that are generated from seeds can spread quickly over the garden and smother nearby plants.

Over the years, I’ve experimented with a variety of Nepeta species and varieties in my gardens. And based on my personal experiences, I can heartily suggest two exceptional, sterile (produces no seeds), long-blooming kinds.

  • Select Blue Nepeta is a low-growing, non-spreading plant with lovely lavender-blue flowers that I chose back in the early 1990s from a patch of plants I discovered in an office park landscape. Shear off the flower spikes just above the leaves in the early summer after the first flush of flowers has gone to encourage the plants to blossom later in the season.
  • Walker’s Low Nepeta: This cultivar, which was not given its name for its size but rather after an English castle, features eye-catching deep blue flowers on tall flower spikes. ‘Walker’s Low’ blooms for several months from late spring to mid-summer and develops as a tidy, non-suckering, well-behaved plant. Stronger reblooming will result with deadheading, which involves shearing off the faded flower spikes just above the foliage.

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.

Nepeta Walkers Low: is it intrusive?

Nepeta, sometimes known as Walker’s Low catmint, is a perennial plant with a mounding and non-invasive growth habit. It can grow up to 30–36 inches wide and tall and is hardy in zones 3–8. Compared to a conventional mint plant, the leaves are more silvery in color.

I cultivate the indigo flowering variation of Walker’s Low catmint. I raise it to create a walkway border. Nepeta will return year after year with simple maintenance because it is a perennial plant.

Catmint spreads, or not?

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 Nepeta return each year?

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.

Cut back on Nepeta, do you?

Nepeta can be pruned back after flowering for a new growth spurt and further display of flowers. As flower buds begin to form, trim back stems by a third to keep plants compact and postpone flowering.
