These two plants can be mistaken for one another by using different names, although they are actually distinct species. Catnip is Nepeta cataria, while catmint is Nepeta mussinii, both of which are members of the mint family. The following are some further variations and parallels between the two plants:
While catmint is frequently used as a lovely, flowering perennial in beds, catnip has a weedier aspect.
Catnip blooms less frequently than catmint. Typically, catnip blooms are white. Flowers on catmint are lavender.
When ought catmint to be sown?
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.
What is the purpose of catmint?
Catmint has a long history of use as a common household plant cure. It is particularly effective in treating digestive ailments and, because it induces perspiration, can help lower fevers. Children’s colds, the flu, and fevers can be treated with this herb due to its moderate action and pleasant flavor.
Citronella
One of the most well-known plants for repelling mosquitoes is the citronella plant, commonly known as the mosquito plant. In fact, citronella is probably one of the components in any candle that claims to keep mosquitoes away.
The citronella plant, as its name suggests, smells like lemons and is simple to grow in any yard or plant pot.
The citronella plant is a sun-loving perennial ‘clumping’ grass that can reach heights of up to 5 or 6 feet (about 2 meters). It does not tolerate frost, therefore if you reside in a region with chilly winters, you should put it in pots and bring them indoors over the winter.
The best varieties of citronella plants to purchase if you want to deter mosquitoes are Cybopogon nardus or Citronella winterianus.
When applied topically, citronella essential oil offers exceptionally excellent defense against insects and mosquitoes, making it one of the most powerful all-natural mosquito repellents.
The fact that citronella oil alone evaporates quite quickly is one thing you should take into account. But according to a study in the Journal of Vector Ecology, combining citronella with vanillin boosted the mosquito-repelling power of the mixture for up to 8 hours1. This indicates that it is equally efficient as DEET, the most widely used chemical ingredient in insect repellents, as an insect repellent.
Another investigation shown that citronella retained its insect-repellent qualities on garments for up to 30 days when combined with gelatin-arabic gum microcapsules2.
Citronella is therefore one of the best natural plants you can use to repel mosquitoes, and this is supported by scientific studies. It is also one of the most effective natural insect repellents. Furthermore, citronella works just as well as chemical-based repellents to keep mosquitoes away while having none of the negative side effects.
Here are some tips for using your citronella plant to keep mosquitoes away:
To ward off mosquitoes, rub all exposed body parts with a few softened citronella leaves that you have between your palms.
You can also prevent mosquitoes from entering your home by placing fresh leaves on window sills.
Lemongrass
Lemongrass is a clumping, dark green herb that can reach heights of 3-6 feet (1-2 meters) and has a pungent lemon aroma.
Lemongrass works well as a mosquito repellant because it also includes citronella oil. Mosquitoes will stay away thanks to its potent lemon aroma.
Catmint
Nepeta faassenii, an oil found in catmint, has been demonstrated in numerous tests to have insect-repelling effects. Catmint possesses qualities that make it a natural mosquito repellent, according to a study published in the journal Parasitology Research3.
Catnip
Catnip and catmint are closely related, and most people think of catnip as a herb that makes cats crazy. Although they are both simple to grow, catnip and catmint have a propensity to take over a garden.
Many people might not know that catnip works well to keep mosquitoes away, though. Additionally, research has demonstrated that catnip possesses insect-repelling qualities. For instance, according to research from Iowa State University, catnip essential oil was 10 times more efficient as an insect repellent than DEET4.
However, if you have cats, you might want to consider growing alternative plants in your garden.
Rosemary
Rosemary is a widely used herb that has a lovely appearance and numerous culinary applications. It thrives both inside and outside. One of the greatest plants for repelling mosquitoes is rosemary (as well as insects and other bugs). One of the plants that deters wasps is this one.
Therefore, to get the most out of rosemary, you should have a pot growing on a windowsill or next to a doorway. This will not only provide color and a great scent to the area, but it will also help keep insects out of the space by blocking their flight.
Basil
Basil may be grown and used as a mosquito repellent and in cooking, similar to how rosemary can. Additionally supported by scientific study is this. For instance, one study found that oils made from turmeric and hairy basil, along with 5% vanillin, effectively repelled three types of mosquitoes for 6 to 8 hours in cage conditions2.
Basil contains anti-inflammatory qualities and can be used to treat mosquito bites in addition to repelling mosquitoes (as I mentioned in my article about the top 15 natural ways to relieve mosquito bites). Basil leaves can be applied directly to the affected area by rubbing them between your fingers or by crushing the leaves in a pestle and mortar and applying the paste to your skin.
Pyrethrum
This plant aids in the prevention of a wide range of insects and pests, such as ticks, aphids, leafhoppers, spider mites, and harlequin bugs, in addition to mosquitoes. Insecticide prepared from dried flower heads of Chrysanthemum cinerariifolium and Chrysanthemum coccineum is known as pyrethrum.
The six esters known as pyretrins, which are active components found in the floral sections termed achenesthe future seeds of Pyrethrum, function as an insect repellent.
Lavender
Due to its relaxing effects and lovely aroma, lavender has a wide range of applications. Additionally, lavender naturally deters mosquitoes. Lavender essential oil is particularly efficient when coupled with other natural oils, according to certain studies5.
Geranium
Geraniums thrive in both indoor and outdoor environments and are prized for their stunning, vivid colors. Mosquitoes and other creatures can be repelled by their aroma. In fact, research on geraniums as a mosquito repellent revealed that it was effective when combined with the oils of lavender and lemon eucalyptus5.
Peppermint
Another plant that deters insects is peppermint. Due to the fact that most insects dislike its potent taste and smell, it is an effective all-purpose insect repellent. According to one study, peppermint oil both kills the larvae of malaria-carrying mosquitoes and works well as a repellent against them6.
Other studies on natural mosquito repellents have revealed the effectiveness of essential oils from the mint family, which are widely used as insect repellents worldwide2.
Rub peppermint leaves on the region where you’ve been bitten by a bug to get the relief you need.
Garlic
Naturally, garlic is well-known for both the health advantages it offers and the strong stench we release after consuming it. Additionally, if we consume too much garlic, it will likely ward off more people than insects!
Fortunately, garlic’s insect-repelling qualities can be experienced without eating it. Few people would like to rub it on their skin to deter insects, especially when there are much better and more pleasant-smelling natural options like citronella.
Garlic has a pungent smell that insects and mosquitoes typically find repulsive, thus it can be effective in warding them off.
Lemon Balm
This also belongs to the mint family and thrives in all environments. Essential oils from the mint family contain insect-repelling qualities, as previously described with peppermint oil.
Marigolds
Marigolds are rarely considered to have any uses other adding color to a garden, but did you know that they also act as a natural insect repellent?
Marigold plants produce flowers that are yellow or orange and have a strong scent. Alpha-terthienyl, a chemical produced by marigolds, has been shown to have insect-repelling properties. The ability of marigold essential oil to deter mosquitoes has also been discovered. 7
Horsemint
This is sometimes referred to as Beebalm, and it has a potent scent that effectively serves as a natural mosquito deterrent. It may be grown in pots and is simple to grow. Therefore, it can deter insects from entering your home when placed next to doors or windows.
Will my garden’s catmint attract cats?
Our Plant Profiles from Plant Select highlight a variety of plants that not only flourish in the Rocky Mountain region but also fulfill essential requirements for animals.
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.
