Why Choose Large Catmint for Your Garden?

Large catmint varieties stand out for their sprawling form, reaching up to 90cm tall with a similar spread. Their silvery-grey foliage and profuse flowering add a soft, textural dimension to any planting scheme. Gardeners love large catmint for its drought-tolerance and deer-resistance—ideal for sustainable and wildlife-friendly gardens. If you want a perennial that covers ground quickly, suppresses weeds, and requires little fuss, large catmint fits the bill perfectly. It’s excellent for edging pathways, filling gaps in mixed borders, or creating drifts of colour in large garden beds.

Top Large Catmint Varieties

One of the most iconic large catmint selections is Nepeta 'Six Hills Giant' (Catmint). Renowned for its vigorous habit, this variety forms tall, bushy clumps topped with long spikes of blue flowers from late spring to autumn. It’s a superb choice for gardeners seeking height and visual impact without the demands of high-maintenance plants.

While Nepeta 'Six Hills Giant' (Catmint) is often synonymous with large catmint, you may also like to explore other excellent Nepeta options. For slightly smaller yet still substantial choices, Nepeta 'Walkers Low' (Catmint) offers compact, floriferous growth ideal for borders. Nepeta mussinii (Catmint) and Nepeta 'Blue Wonder' (Catmint) deliver lush mounds of blooms and fragrant foliage, while Nepeta faassenii is another reliable perennial in the Nepeta family suitable for various garden designs.

How to Grow and Care for Large Catmint

Large catmint is delightfully easy to establish. Plant in full sun or light shade, in well-drained soil. Once settled, these plants are remarkably tolerant of dry conditions and poorer soils. Prune hard in winter or after flowering flushes to maintain tidy growth and encourage reblooming. Large catmint is rarely troubled by pests or diseases, making it a low-effort joy for beginner and expert gardeners alike.

Companion Planting and Uses

Large catmint pairs beautifully with roses, peonies, and ornamental grasses, providing a harmonious backdrop and contrasting colour. Its calming fragrance and leafy stems can be used for herbal teas, or simply enjoyed in situ. Create pollinator-friendly borders by including multiple Nepeta varieties, such as Nepeta 'Walkers Low' (Catmint), Nepeta mussinii (Catmint), and Nepeta faassenii.

It’s easy to fall for Buxus sempervirens (Boxwood) and Schefflera arboricola (Dwarf Umbrella Tree), but Tilia platyphyllos (Large-leaved Lime), Lavender 'Sensation Purple', and Libocedrus plumosa (Kawaka) offer a different kind of delight.
