Understanding the Walkers Low Catmint Plant
When considering a 'Walkers low catmint plant', the reference is typically to varieties of Nepeta that are specifically selected for their compact, ground-hugging habit and often sold through or associated with garden centres like Walkers. These plants are celebrated for their long flowering season, aromatic foliage, and their appeal to pollinators, making them a valuable addition to many UK gardens. Unlike some taller cultivars, low catmints remain tidy, rarely exceeding 30-40cm in height, thus avoiding the need for frequent staking and maintaining a neat appearance even when not in bloom.
- Compact, ground-hugging habit.
- Long-lasting purple-blue flower spikes.
- Attracts pollinators and beneficial insects.
- Drought-tolerant once established.
- Aromatic foliage deters some pests.
The appeal lies in their versatility. They perform admirably in borders, rockeries, gravel gardens, and even containers. Their ability to withstand dry conditions makes them particularly suited to modern gardening needs, where water conservation is increasingly important. The scent of the crushed leaves is often described as minty or lemony, adding another sensory dimension to their horticultural merits.
Choosing the Right Low Catmint Variety
While 'Walkers low catmint plant' might point to a specific product, the broader category of low-growing Nepeta offers several excellent choices. Varieties often favoured for their compact nature include Nepeta x faassenii 'Walker's Low' itself, which, despite its name, is one of the most popular and readily available catmints, known for its prolific flowering and robust nature. Other cultivars to consider for a similar effect might be Nepeta 'Little Trudy', which stays even more diminutive, or Nepeta 'Cat's Pajamas', celebrated for its dense mounds of lavender-blue flowers.
When selecting, consider the mature size and spread. Although they are 'low' varieties, some can still spread to a respectable width, which is beneficial for ground cover but important to note for spacing. The intensity of the flower colour can also vary, from pale lilac to deep indigo blue, and the foliage can range from grey-green to a more vibrant green. Each offers a slightly different aesthetic, allowing gardeners to tailor their choice to specific planting schemes.
Planting and Growing Conditions
What conditions do low catmints need to thrive? These hardy perennials are remarkably forgiving, but a few key considerations will ensure the best display and plant health. They are sun-lovers, demanding at least six hours of direct sunlight per day for optimal flowering. While they can tolerate partial shade, the blooms will be less abundant, and the plant may become leggy.
Soil is another critical factor. Catmints prefer well-drained soil; they absolutely detest waterlogged conditions. If your garden soil is heavy clay, amending it with grit, sand, or compost will significantly improve drainage. A slightly alkaline to neutral pH is ideal, though they are not overly fussy. Many gardeners find that planting them in a gravel garden or a border with good drainage is a recipe for success.
Site Preparation and Planting Technique
Before planting, prepare the site by loosening the soil to a depth of about 20-30cm. If drainage is a concern, incorporate grit or coarse sand generously. For new beds, a general-purpose compost can be mixed in to improve soil structure, but avoid overly rich, heavily manured soil, which can lead to excessive leafy growth at the expense of flowers.
When planting your Walkers low catmint plant, whether it's a specific named cultivar or a general low-growing variety, dig a hole twice the width of the root ball and just as deep. Gently remove the plant from its pot, teasing out any circling roots. Place it in the hole so the top of the root ball is level with the surrounding soil. Backfill with soil, firm gently, and water thoroughly. Allow adequate space for growth; check plant labels for specific spacing recommendations, but generally, allow 30-45cm between plants depending on the variety's mature spread.
If planting in heavy clay soil, consider creating a shallow, wide planting hole rather than a deep one, and incorporate plenty of grit to encourage water to drain away from the roots.Care and Maintenance for Catmint
Once established, low catmints are exceptionally low-maintenance, a key reason for their popularity. Their drought tolerance means they require minimal watering, especially once their root systems are developed. In prolonged dry spells, a good watering at the base of the plant will be beneficial, but avoid over-watering, which can lead to root rot.
Deadheading is beneficial but not strictly essential for the plant's survival. Removing spent flower spikes encourages a second flush of blooms and keeps the plant looking tidier. A hard prune after the first main flowering period, cutting back the plant by about half, can rejuvenate it and promote further flowering into late summer and autumn. This also prevents the plant from becoming too straggly and self-seeding excessively, though its self-seeding is usually manageable.
Pest and Disease Management
Nepeta is generally resistant to most common garden pests and diseases. Its aromatic foliage acts as a deterrent to slugs and snails, and it is rarely troubled by aphids. The primary concern is root rot, which stems from poor drainage. Ensuring the planting site is well-drained is the most effective preventative measure. Overcrowding can also lead to poor air circulation, making plants more susceptible to fungal issues, although this is uncommon with low varieties.
The resilience of low catmint varieties makes them a standout choice for gardeners seeking beauty with minimal fuss.
Fertilising is typically unnecessary. Catmints thrive in lean to moderately fertile soils. Adding too much fertiliser, especially nitrogen-rich types, will promote lush foliage at the expense of flowers and can make the plant floppy. If your soil is particularly poor, a light dressing of compost or a balanced, slow-release fertiliser in spring might be considered, but it's usually not required.
Alternatives and Companion Planting
While the Walkers low catmint plant is a superb choice, exploring alternatives can enhance your garden's appeal. If you seek similar drought tolerance and pollinator attraction but desire different flower forms or colours, consider plants like Sedum 'Autumn Joy' or 'Herbstfreude'. These succulents offer sturdy structure and late-season blooms that are magnets for bees and butterflies, often lasting well into winter.
For a different bloom shape but equally hardy performance, Agapanthus, with their striking globe-like flower heads, can provide a bold statement in well-drained, sunny spots. If you prefer a softer, more informal look, certain varieties of Heuchera offer exceptional foliage colour year-round, often complemented by delicate, airy flower spikes that attract smaller pollinators. For those seeking vibrant colours and a longer blooming season in less arid conditions, consider Dahlias, though they typically require more fertile soil and winter protection in many UK climates.
Complementary Planting Partners
The beauty of low catmint lies not only in its own merits but also in its ability to harmonise with a wide array of other garden plants. Its soft, mounding habit and hazy purple-blue flowers act as a superb filler and softener for more structured plants. Consider pairing it with:
- Ornamental Grasses: Varieties like Stipa tenuissima or Calamagrostis x acutiflora 'Karl Foerster' provide movement and textural contrast.
- Hardy Perennials: Plants such as Echinacea (Coneflower), Coreopsis, or Salvia offer complementary flower shapes and colours.
- Shrubs: Low-growing shrub roses or Lavender cultivars can create a classic, fragrant planting scheme.
- Bulbs: Planted in autumn, bulbs like Alliums or early spring bulbs such as Muscari can provide interest before the catmint fully emerges.
When planning your planting, remember the catmint's preference for sun and excellent drainage. This means companion plants should ideally share these requirements. Avoid planting it directly amongst moisture-loving plants like Hostas or Hellebores, or in deep shade that would suit Foxglove or some Ferns. The goal is to create a cohesive planting that thrives under similar conditions, ensuring all elements contribute to a beautiful and sustainable garden display.
