Understanding Walker's Low Nepeta Catmint
Walker's Low Nepeta catmint is a particularly popular cultivar celebrated for its compact, mounding habit and prolific, long-lasting blooms. Unlike some taller varieties of Nepeta, such as Nepeta x faassenii, this selection stays at a more manageable height, typically reaching around 18-24 inches (45-60 cm) in both height and spread. Its foliage consists of aromatic, grey-green leaves that release a delightful scent when brushed against, a characteristic that makes it particularly appealing to cats. The plant produces dense spikes of small, lavender-blue flowers from late spring through to autumn, providing continuous colour and attracting bees, butterflies, and, of course, cats.
This perennial is renowned for its resilience. It thrives in full sun and tolerates a wide range of soil conditions, provided they are well-draining. Its drought tolerance once established means it requires minimal watering, making it an excellent choice for low-maintenance gardens, rockeries, or borders where water conservation is a priority. The 'Walker's Low' cultivar is valued for its tidy appearance, generally resisting the flopping or spreading that can sometimes affect other catmint varieties.

Benefits for Gardeners and Wildlife
Beyond its aesthetic appeal and feline allure, Walker's Low Nepeta catmint offers substantial benefits to the garden ecosystem. Its flowers are a magnet for pollinators, providing a crucial nectar source for bees and butterflies throughout the blooming season. The fragrant foliage deters some common garden pests, contributing to a healthier plant environment without the need for chemical interventions. For cat owners, the plant serves as a natural and safe attractant, often leading to entertaining observations as cats roll, rub, and play amongst the stems. Its hardiness, coupled with its beneficial insect-attracting properties, positions it as a sustainable and rewarding addition to almost any garden design.
Understanding the 'Low' in Walker's Low
The designation 'Low' in Walker's Low Nepeta catmint is a key differentiator from other popular varieties. While standard catmint can grow to be 3 feet (90 cm) or more, this cultivar is specifically bred for a more restrained growth habit. This means it's less likely to overshadow smaller plants or become unruly in confined spaces. This compact nature is particularly advantageous for front-of-border planting, container gardening, or when creating a cohesive planting scheme where plant heights need careful management. Its reduced stature also means it's less prone to wind damage and can maintain a neat appearance with minimal intervention.
Cultivating Your Walker's Low Nepeta Catmint
Successful cultivation of Walker's Low Nepeta catmint hinges on providing the right conditions from the outset. The most critical factor is sunlight; this plant performs best in full sun, meaning at least six hours of direct sunlight per day. While it can tolerate partial shade, flowering will be less abundant, and the plant may become leggy. Good drainage is equally paramount. Nepeta dislikes waterlogged soil, which can lead to root rot. If your soil is heavy clay, amend it generously with grit, sand, or compost to improve aeration and drainage before planting. Raised beds or containers are also excellent options for areas with poor natural drainage.
Planting and Initial Care
When planting, dig a hole that is twice the width of the plant's root ball and of a similar depth. Gently tease apart any circling roots before placing the plant in the hole, ensuring the top of the root ball is level with the surrounding soil. Backfill with soil, firm gently, and water thoroughly. For container planting, use a good quality, well-draining potting mix. Water regularly until the plant is established, then reduce watering frequency. The plant is highly drought-tolerant once mature, so overwatering is a more common pitfall than underwatering.
Water deeply but infrequently once established, allowing the soil to dry out between waterings to encourage strong root development and maximise drought tolerance.
Pruning for Longevity and Bloom
Pruning is a key horticultural practice for Walker's Low Nepeta catmint, primarily to encourage reblooming and maintain its tidy shape. After the initial flush of flowers in early summer, a hard prune can be highly effective. Cut back the entire plant by about one-third to one-half its height. This encourages new growth and often results in a second, strong wave of blooms in late summer or early autumn. Remove any dead or spent flower stems throughout the season as they appear to keep the plant looking its best.
Further pruning may be needed in late autumn or early spring to remove any winter damage or to tidy the plant's overall form before the new growing season begins. Avoid pruning too late in autumn if you want to provide some winter interest, as the dried flower stems can add structure to the winter garden.
Soil and Fertiliser Requirements
Walker's Low Nepeta catmint is not a demanding plant when it comes to soil fertility. In fact, overly rich soil can lead to excessive leafy growth at the expense of flowers and can make the plant more prone to flopping. For most garden situations, amending the soil with compost at planting time is sufficient. If you choose to fertilise, opt for a balanced, slow-release fertiliser applied sparingly in early spring. Avoid high-nitrogen fertilisers, which can promote lush foliage but fewer blooms.
Pest and Disease Considerations
This variety of catmint is generally resistant to most common garden pests and diseases. Its aromatic foliage acts as a natural deterrent to many insects, and its hardiness makes it robust against fungal issues, provided good air circulation and drainage are maintained. The primary concern is root rot due to poor drainage or overwatering. Aphids can occasionally appear on new growth, but they are usually managed by beneficial insects or can be washed off with a strong jet of water. Healthy plants grown in appropriate conditions are the best defence against any potential problems.
The plant's resilience makes it a low-risk choice for gardeners seeking reliable blooms.
Attracting Cats and Other Wildlife
One of the most charming aspects of growing Nepeta, and specifically the Walker's Low variety, is its magnetic pull for domestic cats. Many felines react to Nepeta similarly to catnip (Nepeta cataria), rolling, rubbing, and exhibiting playful behaviour when exposed to its scent. This reaction is due to nepetalactone, a volatile oil present in the plant's tissues. While not all cats respond, a significant percentage find Nepeta irresistible, offering a safe and entertaining way to engage with your garden.
Maximising Feline Interest
To ensure your Walker's Low Nepeta catmint plant is as appealing as possible to cats, consider its placement. Planting it in an area where cats frequently visit or play can increase their interaction. Gently brushing against the foliage when the plant is dry can release more of its aromatic oils, amplifying its allure. While the plants are generally robust, be prepared for enthusiastic feline visitors who might roll on, or even briefly chew on, the plants. Fortunately, the plant's vigorous nature and rapid regrowth usually mean that even a heavily 'loved' plant will recover quickly.
It's worth noting that the intensity of the cat-attracting properties can vary between individual plants and even at different times of the year. Some gardeners find that plants grown in drier conditions or with less fertiliser can have a stronger scent. If you're aiming for maximum feline fascination, ensure your plant is in full sun and has excellent drainage, as this promotes the concentration of aromatic oils.
A Haven for Pollinators
Walker's Low Nepeta catmint is also a significant draw for beneficial insects. Its abundant, nectar-rich flowers are a favourite of many species of bees, including bumblebees and solitary bees, as well as various types of butterflies. By incorporating this plant into your garden, you actively contribute to supporting local pollinator populations, which are vital for the health of ecosystems and for fruit and vegetable production in nearby gardens. The plant's long blooming period ensures a sustained food source, making it a highly valuable addition to any wildlife-friendly garden.
The subtle fragrance of the plant also helps in attracting other beneficial insects that may prey on garden pests. This dual benefit—attracting pollinators while potentially deterring pests—enhances the plant's value beyond mere aesthetics. It's a living, breathing part of the garden's ecosystem, supporting biodiversity and contributing to a more balanced natural environment. Planting it near vegetable patches or fruit trees can further encourage pollination and natural pest control.
The plant's dual appeal to cats and pollinators makes it a garden star.
Alternatives to Walker's Low Nepeta Catmint
While Walker's Low Nepeta catmint is a superb choice, various other plants can offer similar benefits, whether you're seeking specific drought tolerance, aromatic foliage, pollinator attraction, or cat-friendly properties. Exploring alternatives allows for tailoring your garden to precise needs and aesthetic preferences. Some options provide similar lavender-blue blooms, while others excel in different aspects like foliage texture or bloom duration.
Other Nepeta Varieties
Within the Nepeta genus itself, several other cultivars offer distinct characteristics. 'Six Hills Giant' is a much larger, more vigorous variety that can reach up to 3 feet (90 cm) tall and spread wide, making it suitable for larger landscapes but less so for confined spaces. 'Little Trudy' is another compact option, often staying under a foot (30 cm) tall, with darker green foliage and a denser flower habit. 'Cat's Pajamas' is known for its very long bloom time and compact, upright habit. Each offers the signature aromatic foliage and pollinator-attracting flowers, with differences primarily in size and growth habit.
If the primary goal is to attract cats, it is worth noting that while many Nepeta species and cultivars are appealing, Nepeta cataria (true catnip) is often considered to have the most potent effect. However, catnip can be more prone to spreading and may not have the same refined ornamental qualities as cultivated varieties like Walker's Low.
Drought-Tolerant Perennials with Similar Blooms
For gardens prioritising drought tolerance and similar flower colours, several other perennials can serve as excellent companions or substitutes. These plants often thrive in sunny, well-drained conditions and require minimal watering once established.
| Plant Type | Key Features | Considerations |
|---|---|---|
| Agapanthus | Large globes of blue or white flowers on tall stems. Very drought-tolerant once established. | Prefers well-drained soil; some varieties require winter protection in colder climates. |
| Salvia (Perennial varieties like Salvia nemorosa) | Spikes of purple, blue, or pink flowers; aromatic foliage; attracts pollinators. | Requires full sun and good drainage; benefits from deadheading for rebloom. |
| Veronica (Speedwell) | Spikes of blue, purple, pink, or white flowers; attracts bees and butterflies. | Prefers moist, well-drained soil but many varieties tolerate drier conditions; needs full sun. |
| Echinacea (Coneflower) | Daisy-like flowers, often in shades of purple and pink, but also orange and white; attracts pollinators. | Very drought-tolerant, prefers full sun; attractive seed heads for winter interest. |
Aromatic Alternatives
If the aromatic foliage is a key appeal, consider other fragrant herbs and perennials. Lavender (Lavandula) offers beautiful purple spikes, a calming scent, and excellent drought tolerance, though it prefers slightly alkaline soil. Rosemary (Salvia rosmarinus) provides evergreen, aromatic foliage and blue flowers, thriving in hot, dry conditions. Thyme (Thymus spp.) offers low-growing, fragrant groundcover with small flowers. While these won't necessarily attract cats, they provide sensory appeal and support pollinators.
For a different textural and colour element that also thrives in similar conditions, consider plants like Sedum varieties, which offer succulent foliage and late-season blooms, or ornamental grasses that provide movement and structure. Pairing these with plants known for attracting cats, like Valerian (Valeriana officinalis), can create a garden that appeals to both humans and their feline companions, as well as beneficial insects.
Choosing alternatives depends on prioritising bloom colour, drought tolerance, or specific wildlife attraction.
