Its suitability for a range of garden styles, from cottage gardens to contemporary, gravel-based designs, underscores its versatility.
For those seeking reliable, long-lasting colour and a plant that supports local wildlife, 'Walker's Low' is an excellent choice. Its ability to withstand dry conditions once established means it’s well-suited for challenging spots or for gardeners looking for plants that require less watering.
Key Characteristics of 'Walker's Low'
When considering Nepeta 'Walker's Low' for your garden, understanding its specific attributes is crucial. The plant typically grows to a height of around 60-90 cm, with a spread that can extend up to 1 metre. This makes it a substantial groundcover or a mid-border perennial. The flowers are a vibrant lavender-blue, borne on upright stems, and continue to appear prolifically if spent blooms are regularly removed. The foliage is a soft, silvery-green and highly aromatic, releasing its characteristic scent when brushed or crushed. This variety is particularly noted for its excellent mildew resistance, a common issue with some other Nepeta cultivars, ensuring it maintains a healthier appearance.
It performs best in full sun, though it can tolerate partial shade, which might result in slightly less prolific flowering. The soil preference is for well-drained conditions; it dislikes waterlogged ground, making it ideal for gravel gardens or slopes. Its hardiness means it can typically survive cold winters outdoors in most of the UK, emerging vigorously in spring. Pruning back after the first flush of flowers can encourage a second bloom and keep the plant tidy.
Cultivating Your Catmint 'Walker's Low'
How do you ensure your Nepeta 'Walker's Low' thrives and delivers that spectacular, long-lasting display? Successful cultivation centres on providing the right conditions and performing simple, timely maintenance. It's a plant that rewards minimal fuss with maximum impact, making it a favourite for both novice and experienced gardeners.
Planting and Soil Preparation
Choose a sunny position for your catmint; the more sun, the more flowers it will produce. While it tolerates some shade, flowering will be reduced. The most critical factor is soil drainage. Nepeta 'Walker's Low' will not tolerate heavy, waterlogged soil. If your garden has clay soil, amend it generously with grit or sand to improve drainage, or consider planting it in raised beds or containers filled with a well-draining compost mix. Dig a hole twice the width of the root ball and to the same depth. Gently loosen the roots if they are pot-bound before placing the plant in the hole. Backfill with soil, firm gently, and water thoroughly. Space plants about 60-90 cm apart to allow for their mature spread.
Deadhead spent flowers regularly to encourage repeat blooming and maintain a neater appearance throughout the season.
Watering and Feeding
Once established, Nepeta 'Walker's Low' is remarkably drought tolerant. Water new plants regularly until they are settled, but established plants only require watering during prolonged dry spells. Overwatering can lead to root rot and reduced flowering. Feeding is generally not necessary, as catmint prefers leaner soils. Excessive feeding, particularly with high-nitrogen fertilisers, can lead to lush foliage at the expense of flowers and may cause the plant to become leggy. If your soil is particularly poor, a light mulch of compost in spring can provide sufficient nutrients.
Pruning and Maintenance
To keep 'Walker's Low' looking its best, a light trim after the main flowering flush in mid-summer is beneficial. Cut back the flowered stems by about a third to a half. This often stimulates new growth and a second, albeit usually less prolific, wave of flowers. A more severe cut to the ground can be done in late autumn or early spring before new growth begins. This helps to remove dead foliage and tidy up the plant. Its inherent mildew resistance means it generally requires little intervention, but ensuring good air circulation around the plant by spacing it correctly can further prevent issues.
The true charm of 'Walker's Low' lies in its unfussy nature and its ability to provide continuous visual appeal with minimal intervention.
The key to maintaining its shape and encouraging re-blooming is consistent deadheading.
Exploring Alternatives to 'Walker's Low' Catmint
While Nepeta 'Walker's Low' is an exceptional plant, your garden's specific conditions or your aesthetic preferences might call for alternatives. Whether you seek a different flower colour, a more compact form, or plants with a similar drought tolerance and pollinator appeal, several excellent options exist. Considering these alternatives ensures you can achieve a similar garden effect, even if 'Walker's Low' isn't the perfect fit.
Compact or Dwarf Catmint Varieties
If space is limited or you prefer a tidier, more contained plant, several dwarf or compact catmint varieties are available. For instance, Nepeta 'Little Trudy' offers a similar lavender-blue bloom but remains much smaller, typically reaching only 30-45 cm in height and spread. Another option is Nepeta x faassenii 'Six Hills Giant', which, despite its name, is often considered a parent variety and can be quite vigorous, but also offers abundant flowers. Nepeta 'Junior Walker' is a more restrained version of 'Walker's Low', offering a similar look but in a more compact habit, usually around 60 cm tall. These smaller cultivars are ideal for the front of borders or for container planting.
Other Pollinator-Friendly Perennials
For a similar effect to catmint in attracting bees and butterflies, and offering long-lasting blooms, consider other hardy perennials. Salvias, such as Salvia nemorosa varieties like 'Caradonna' or 'Mainacht' (May Night), offer striking spikes of deep purple-blue flowers that bloom for an extended period, particularly when deadheaded. They also prefer sunny, well-drained conditions. Lavender (Lavandula) is another classic choice, famed for its scent and purple blooms, though it requires excellent drainage and can be less tolerant of heavy soils than Nepeta. Agapanthus, with their striking globe-shaped flower heads in shades of blue and white, also provide a similar long flowering season and are drought-tolerant once established, though they may require winter protection in colder regions.
| Plant Type | Key Features | Growing Conditions |
|---|---|---|
| Nepeta x faassenii 'Little Trudy' | Compact, lavender-blue flowers, aromatic foliage. | Full sun, well-drained soil. |
| Salvia nemorosa 'Caradonna' | Deep purple-blue spikes, long flowering, attractive to pollinators. | Full sun, well-drained soil. |
| Lavandula angustifolia (English Lavender) | Fragrant purple flowers, silvery foliage, very drought tolerant. | Full sun, exceptionally well-drained soil. |
| Agapanthus spp. (Lily of the Nile) | Large blue or white flower globes, long blooming, drought tolerant once established. | Full sun to partial shade, well-drained soil. |
When selecting an alternative, always consider the mature size, soil and sun requirements, and flowering period to ensure it integrates well into your garden design and thrives in your specific microclimate. Many of these alternatives, like dahlias or peonies, offer different forms of beauty but may require more specific care or different soil conditions than the unfussy catmint.
When choosing alternatives, observe plants that perform well in local gardens or visit a reputable nursery to see which options are best suited to your region's climate.
Drought-Tolerant Companions
For a cohesive planting scheme that minimises watering needs, pair 'Walker's Low' catmint with other drought-tolerant perennials. Sedum varieties, such as Sedum 'Autumn Joy', offer succulent foliage and late-season flower heads that provide structure and colour. Ornamental grasses, like Calamagrostis x acutiflora 'Karl Foerster', can provide vertical interest and movement, thriving in similar sunny, well-drained conditions. Heuchera, while preferring more moisture than catmint, can perform well in dappled shade with good drainage and offers striking foliage colours. For a bolder statement, consider plants like Echinacea (coneflower) or hardy Geranium varieties that can tolerate dry spells once established, complementing the catmint's long bloom time.
