Hahaha, thank you That’s flattering, Jo, and I appreciate it. In the UK, it is really categorized as a “half-hardy perennial,” which means that it dislikes our harsh winters. Since it was so mild there, I used to have a few naturalized areas of it at the cottage. However, LLL advice is the best; take some and you should be fine wherever you are. It readily takes root along the stem, so if you peg a strand around the rim of a pot, it will take root at each nodule. In the spring, you can simply divide it into plantlets and let them develop. The one with simple green leaves is more resilient than the variegated one, which is frequently sold as bedding in the UK. I’m not sure if you’ve heard of it, but there’s a cute little trailing mint, Satureja douglasii, that you can buy that would definitely be hardy for you and smells wonderful as well.
How is a Nepeta maintained?
- Catmint should be planted in a warm, bright (or somewhat sunny) location from spring through autumn; full sun produces the nicest blossoms.
- While necessitating ordinary water, once established, necessita becomes drought-tolerant.
- Catmint may thrive in a range of soil conditions.
- Trim spent blooms to retain compactness and encourage repeat bloom.
- Early spring is a good time to separate catmint clumps.
I frequently plant Nepeta ‘Walker’s Low’, a gorgeous tidy mounding cultivar that bears deep blue flowers on erect stems, in the gardens of my clients. (It forms clusters up to 18 inches wide and grows to a height of between 18 and 24 inches.)
Is nepeta a perennial herb?
Catmint is a low-maintenance perennial herbaceous plant that swarms the garden with pollinators. It contains clusters of fragrant lavender-blue flowers that resemble lavender and are sweet-smelling. Learn how to cultivate catmint, often referred to as nepeta, and add this perennial with a protracted bloom period to your garden.
There is a functional similarity between catmint and lavender. The plants are closely related and are members of the Lamiaceae family, which is a large family.
A perennial flower that grows well with other cottage garden flowers is catmint. Due to its moderate growth rate, it is frequently grown as a companion plant for roses, planted as an underplanting.
Catmint plants are a great example of a perennial because they frequently come back to the garden year after year.
Perennials typically don’t bloom as abundantly as some of the garden’s annual flowering plants.
Every year, perennials typically bloom for two to four weeks, with some having a second, less prolific flowering period later in the season.
With a little attention in the middle of the growing season to encourage the second flush of flowers, this perennial can bloom from early spring into early October. It is a perennial flowering plant with numerous garden advantages.
Does catmint get pruned back in the fall?
Catmint and I have a love-hate relationship. If you have a LOT of space for it to take over, it’s a terrific plant for providing cold tones to a space. Fortunately, catmint can be severely trimmed at any time of the year.
You can trim these back in the fall to just a few inches above the ground, but your garden will have a hole in it until they grow back flush in the spring.
If catmint is the cornerstone of your perennial border, regular summers pruning should be combined with more restrained trims of around half the plant’s height during the fall.
Is nepeta a plant that trails?
Nepeta is a leafy trailing plant that is always in demand for hanging baskets. The long, trailing green branches have a distinct smell and cream splashes on them. An vital plant to provide any hanging basket contrast and structure.
Does catmint withstand frost?
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.
How can I grow catmint in the winter?
- ‘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!
Nepeta spreads, right?
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.
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.
Is nepeta a perennial plant?
Are you interested in learning more about Nepeta racemosa “Walker’s Low”? Catmint is another name for Nepeta racemosa, often known as “Walker’s Low.” The maximum height of this Lamiaceae is roughly 60 centimeters. Walker’s Low Nepeta racemosa is not an evergreen plant. Would you like more details or advice about Nepeta racemosa “Walker’s Low”? Please keep in mind that depending on the season, we might not currently have this Catmint in stock when visiting our garden center.
Is catmint a biennial or annual plant?
Catmint is incredibly adaptable and simple to grow, making it one of the perennial powerhouses of the plant kingdom. Early summer is when deep purple blossoms burst into color and put on a long-lasting magnificent display.
Catmint: is it an invasive species?
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.
