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 because they can withstand drought, bloom for a long time, and withstand our extreme weather.
That is, almost flawless, barring two things. 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.
How can catmint be resisted by cats?
Nepetas, sometimes known as catmints, are becoming more popular as perennials due to their lengthy flowering season, appealing coloring, and thick growth. There is only one issue: cats!
Cats adore this plant, which is why it’s called catmint. Cats can be attracted to catnip, a nepeta (Nepeta cataria), which is an old feline favorite. They scuff against it, roll about on it, and rub against it. They are drawn to the nepetalactone that injured leaves and stems release. And nepetalactone sensitivity affects around two-thirds of domestic cats.
As catnip (N. cataria) is typically grown for feline amusement and isn’t particularly attractive, this isn’t typically a concern. The other nepetas, however, are decorative trees. You don’t want cats digging them up or scratching them to death. True, they emit a lot less nepetalactone than catnip, but cats may still get them all messed up.
Some roots and leaves will surely be broken or injured while planting, releasing nepetalactone and attracting cats as a result. Therefore, to deter cats, cover newly planted nepetas with some form of barrier (a cut-off gallon milk container, for example). The smell that was unintentionally produced during planting will be gone after 4 or 5 days, and cats won’t be a problem.
If you inadvertently wound or crush your nepeta, it will live a lovely, cat-free life, so keep your cat barrier close by!
Can cats tolerate catmint?
They work best when placed around the borders of flower beds or at the entrances to your garden.
Due of the fragrance or texture, cats will be less likely to cross them or go by them.
They will also be hesitant to jump over, especially if they are unable to see past the plant.
Lavender
The reason we’ve ranked this plant at the top is that cats dislike the smell that humans find so alluring, which makes it an extremely effective cat repellent.
Lavender will give your flower beds a lovely purple tint and is a perennial plant.
Those of you who are more inventive in the kitchen might be able to use it as well.
Rosemary
Lavender is a popular cat deterrent with a pleasant scent, while rosemary is also a popular cat deterrent with a human draw.
It has similar advantages to lavender, including being lovely and evergreen, but it is simpler to utilize in cooking.
Curry Herb Plant
According to one website’s description of this herb, “Cats don’t enjoy curry.
Curry herb isn’t as popular as some other options because some other plants don’t like it either.
Cats and other animals will take precautions to avoid brushing past this plant because of the stench it releases when they do.
Pennyroyal
a member of the mint family that, when crushed or brushed by, gives off a peppermint-like scent.
Cats dislike the smell and would want to completely avoid it, just like they do with the other highly fragrant plants on our list.
Scaredy Cat Plant
The effectiveness of this herb, which is native to Africa, India, and Indonesia, is still up for debate. [source]
Many websites assert that Plectranthus Caninus, sometimes known as the scaredy-cat plant, naturally repels cats and other animals, while Wikipedia is less certain, claiming that “no study currently exists that supports such practice.”
If you decide to gamble on this plant, be careful not to overpay to a vendor who is attempting to capitalize on its name and reputation.
Any Plant With Thorns
No cat will risk skewering itself while using the restroom because spiky thorns are a less subtle deterrent than aromas and fragrances.
If you choose the thorny route, you have a variety of options: dense shrubs like blackberry or even holly will build strong barriers, while rose bushes will produce lovely flowers if you take good care of them while still deterring cats.
As boundary defenses, shrubs are particularly effective: if a cat encounters a wall of thorny holly on their way into your garden, it’s likely that they’ll turn around and search somewhere else.
Catnip
Catnip can be planted in one section of your garden to draw cats away from other places if you wish to approach the situation differently.
Most cats can’t resist the natural high that this plant, often referred to as catswort, catwort, and catmint, gives them.
Few people are aware that you may produce your own at home, despite the fact that the dried form is well-liked at pet stores and utilized in a variety of cat toys.
Cats will almost surely stop to investigate if they smell this, so consider planting a small amount in a hidden spot in your garden to entice the cats away from your valued beds.
What affects cats does catmint have?
The key distinction between catnip and catmint for gardeners who have cats is that only the latter will stimulate cats and make them go wild. Nepetalactone is a chemical found in catnip plants. Cats adore this, which is what makes them want to eat the leaves that make them feel happy. Nepetalactone is okay to have about the house because it also deters insects.
According to some reports, certain cats are interested in catmint. If they do, they’re more inclined to roll around in the leaves rather than consume them like cats do with catnip. Catnip is the best option if you’re wanting to cultivate a plant only for your cats’ amusement, while catmint is a nicer perennial with more consistent blossoms.
Does catmint draw in other creatures?
Nepetalactone, a substance found in catnip (Nepeta cataria), is attractive to many cats, including tigers and other wild cats. Cats generally respond by rolling, gnawing, or rubbing against the plant or the leaves. If they see that you have any catnip residue on your shoes, they might even go a bit wild.
While some cats become incredibly lively, others become tense, hostile, or drowsy. They might drool or purr. Only five to fifteen minutes pass between catnip reactions. Despite the possibility of a little stomach upset from consuming a big amount, catnip is “purr-fectly harmless and non-addictive.
It’s also typical if your cat exhibits no interest in catnip. Catnip sensitivity is inherited, and between one-third and fifty percent of cats are completely unaffected by the herb.
Which plants are cat-haters?
Cats digging in your garden can be an annoyance and a major health danger (since some cat feces contain toxoplasmosis, which can spread). It might even be your pet! (Image courtesy of Felicia D’Ascano on Unsplash)
Neighbourhood kitties digging in your garden can be a nuisance. Maybe it’s even your own cat!
- Carnivores include cats. Their feces may carry infections or parasites that aren’t found in the dung of herbivores. The majority of us intend to eat the food we cultivate, therefore this is alarming! (The same holds true for dog waste.)
- Every year, over 140 million (birds and small animals) are killed by stray domestic cats. And if you’re doing it right, your garden and yard are made to draw wild birds as well as pollinators like hummingbirds.
- Neighborhood relationships may be strained by roaming cats.
To prevent cats from entering your beloved vegetable beds and eating the food you raise, use these solutions:
Prickly is best
Cats will steer clear of spiky areas and prefer to walk on soft, loose soil. Create a less appealing or litter-like atmosphere in your garden beds. Try these straightforward, inexpensive remedies for prickly problems:
- Twigs should be used to cover cat-friendly garden soil until your spring plants are well-established. They should be spaced a few inches apart all over the bed. Bear in mind that twig bundles aid wild bees!
- Push thorny yard trimmings, such as pine cones or fall leaves, into the soil around your plants. Other choices include recycled plastic carpet runners with the nub side up, stone mulch, eggshells, holly cuttings, and so forth.
- Use wooden chopsticks to repurpose as garden stakes! Try different spacings. The goal is to space them out so that it will be difficult for the cat to turn around.
- Over the earth, place chicken wire or plastic fencing pieces. (Many plants will increase as a result of this!) Lattice pieces on the ground can also be effective.
- By laying out onion or potato mesh produce bags in the garden and securing them with twigs or posts, you can recycle them. If required, widen the opening around your developing plants. Keep a watch on any plastic items you put to the garden to prevent wind from carrying them away and making them litter.
Use scent to keep the cats away
- Rue, lavender, pennyroyal, Coleus canina, and lemon thyme are all pungent to cats. These should be scattered around the garden. (Planting new plants can draw pollinators and other helpful insects.)
What vegetation deters cats from peeing in your garden?
Rue, lavender, pennyroyal, Coleus canina, and lemon thyme are all pungent to cats.
Citrus-loving cats will be discouraged by any fruit peelings, such as those from oranges and similar fruits.
There are also several commercial cat deterrents that mimic the smell of predator urine, but you should only use non-toxic, organic products to protect your flora and wildlife.
Which flowers deter cats?
Even if you adore cats, you don’t want stray cats to stroll around your yard, and you should know how to prevent cats from defecating in your garden. A simple and reliable preventative is to grow plants that repel cats. See our ten recommendations.
Geraniums (Pelargonium)
If you want to add color to your landscape while using a natural cat deterrent, geraniums are a great option. These garden plants give off a nice smell to humans, but most cats find them offensive to their sense of smell. Geraniums are typically an outdoor plant, but they may also be kept within throughout the winter if they are given the right care.
Water geraniums sparingly and only when the leaves start to droop, according to proper care instructions. As new growth forms, remove the old, dead leaves.
Allow the soil to dry completely before watering, and reduce watering throughout the winter but not enough to let the roots dry out. Deadhead blooms to encourage new ones and pinch stems to encourage a bush-like look.
Keep Cats AwayScaredy Cat Plant (Coleus canina)
You might assume that these are the finest plants for deterring cats based just on their names, but the smell is actually what does it. Due to the fact that neither cats nor dogs like the aroma, these are plants to keep them away. Not everyone likes these plants since they smell extremely like pee.
When growing the Scaredy Cat Plant, arrange them in a ring or a line immediately in the trouble spots. Cats won’t get around them to access the other parts of your garden. You might be amazed at how simple it is to maintain these plants because they require little work. If your cat uses dry portions of the garden as a litter box, plant one of these there because it thrives in dry conditions.
Pennyroyal (Mentha pulegium)
Pennyroyals, the tiniest member of the mint family, aren’t only plants that keep cats away—they also ward off a number of insects. This herb is a great option if you prefer using the plants you cultivate because it is stronger and far more potent than other mint herbs in the family.
The herb is frequently used in teas when it is extracted. The American Pennyroyal should not be confused with the European variety. The low-growing plant has hairy stem roots that can reach heights of up to a foot.
Pennyroyal roots anywhere it touches the ground, making it a great flower for use as ground cover. As a border plant for a cat repellant, the new Pennyroyal plants perform admirably. The plant thrives in zones 5 through 9, prefers full sun, but may take some shade.
Lavender (Lavandula)Cat Repellent Plants
While most people enjoy the aroma of lavender, cats do not, for some reason, therefore it is a great choice for plants that deter cats. One of the best plants for repelling insects and wildlife, shrubby lavender plants are also great cat deterrents. It is recommended to place them in a line when using them to keep cats out of your garden.
The vast array of choices with lavender is one problem you may run into. The taller types are the most successful at deterring cats, however all help.
Cats are jumpers, but they are less inquisitive if a bush covers their view, as the taller lavender plants do. As these bushes produce their lovely aroma anytime something brushes against them, planting them along borders also helps to scare cats away.
Common Rue (Ruta graveolens)
Cats stay away from the Common Rue because of its musty smell, but cats don’t want to eat its leaves because of its bitter flavor. When planting the shrub in garden beds near youngsters, use caution because it is deadly if eaten.
A well-drained, dry to moderately damp soil is ideal for the evergreen shrub’s growth. The bush prefers direct sunlight, but will tolerate some shade, poor soil, and poor drainage.
Rue thrives in zones four through eight, although it needs winter mulch and does not like soggy ground. It should only be placed in the middle or front rows of garden beds when being used to dissuade cats because its height and spread are only up to three feet.
Rosemary (Rosmarinus officinalis)Plants that Keep Cats Away
A woody perennial with a Mediterranean origin, rosemary. The perennial is not only effective in keeping cats out of your garden, but it is also incredibly beneficial in the kitchen. When planting rosemary, keep in mind that it does not thrive in cold weather or moist soil. Instead, it loves a dry, moderately warm climate.
These plants prefer neutral to alkaline soil, so use a high-quality compost with a pH of 7. Rosemary grows best when planted in a container since you can bring it inside when the weather changes if you live in a region that is colder than Zone 9 on the US hardiness map.
Alternatively to being a perennial plant, rosemary can also be grown as a summer annual. Cats are scared away by the smell of the plant, so placing containers next to flowerbeds or along the patio can also assist.
Curry Plant (Helichrysum augustfolium)
Many people consider this plant to be an annoyance when it naturally occurs, however these pungent-smelling plants are effective cat deterrents. The shrub grows to a height of two feet and a width of three feet and needs direct sunlight. Offer the curry plant protection from wind and moisture when growing it in gardens.
This plant is effective in keeping cats away, but it also serves as a deterrent for deer. Small yellow blooms on a shrub that grows well in USDA hardiness zones 8 through 11, the curry plant is offered. You should be aware that it can be challenging to remove the plant if you ever decide to do so.
Despite having a curry-like scent, the plant is not a herb and cannot be used in cooking. The plant thrives in arid and deficient soil.
Plants that Deter CatsCitronella (Pelargonium graveolens citrosa)
Citronella, widely known as the mosquito plant because it helps ward off mosquitoes, also acts to deter cats. Cats, mosquitoes, and other insects do not like the aroma that the geranium citronella releases, which is pleasant and citrus-like to humans.
When brushed against to release its aroma, citronella works in garden beds or containers put throughout the patio and along walkways.
Avoid overfertilizing these plants because too much nitrogen lessens the scent of the leaves. Despite being a perennial, citronella is a delicate plant that struggles in colder areas.
Before the first frost, always relocate indoors; otherwise, treat it as an annual. The plant needs light, well-draining soil that is kept on the drier side, and it enjoys partial shade.
Lemongrass (Cymbopogon)
Lemongrass can grow up to five feet tall and is found in thick, grassy bunches. This tropical herb is frequently used in garden beds as ornamental grasses because of its resemblance in look. One of the many advantages of lemongrass as a herb is its capacity to deter cats and other pests with its lemony-citrus fruit aroma.
Never plant lemongrass in clay soil because it is a tropical plant that prefers moisture and would quickly perish if left in wet soil. Even in hotter areas, Lemongrass should be planted in a location that provides full sun.
Lemongrass needs well-draining soil with consistent hydration because it is a tropical plant, which prevents the roots from drying up. Use high-quality potting soil for planting in a pot, one that is at least 12 inches across.
