Why Choose Nepeta Six Hills Giant in New Zealand Gardens?

Perfectly suited to New Zealand’s diverse climates, Nepeta Six Hills Giant thrives in full sun and well-drained soils. Its vigorous growth habit sees plants reach up to 90cm tall and 90cm wide, creating a luxurious fountain of cool tones through summer. The grey-green leaves are semi-evergreen in milder regions, offering year-round texture and gentle fragrance that’s known to deter rabbits and deer.

Gardeners love this cultivar for its resilience—it handles drought, resists most pests, and shrugs off humidity. Prune back after flowering to encourage a second flush of blooms and keep your borders neat.

Design Ideas and Plant Companions

Nepeta Six Hills Giant NZ excels in mixed perennial borders, mass plantings, and naturalistic meadows. Its airy flowers pair beautifully with bold-leaved classics like Hosta Blue Angel and Bergenia 'Joy Bells' (Heart Leaf Bergenia), while their silvery foliage highlights brighter hues from perennials such as Crocosmia crocosmiiflora or the pure tones of Helleborus White Hybrid (Hellebore).

For a continuous colour theme, consider mixing with other catmints like Nepeta 'Blue Wonder' (Catmint), Nepeta 'Walkers Low' (Catmint), Nepeta faassenii, or Nepeta mussinii (Catmint). Taller salvias such as Salvia Azure Snow (Azure Snow) also make striking companions, enriching garden beds with layers of violet, blue, and white.

Caring for Nepeta Six Hills Giant

Plant Nepeta Six Hills Giant NZ in a sunny location with good air circulation. It’s robust enough for exposed coastal gardens and rocky beds, and, once established, rarely requires supplemental water except in extreme drought. Deadheading will prolong the flowering period, while a hard trim in autumn or early spring keeps plants tidy and encourages lush, compact regrowth.

Nepeta is also famously pet-friendly—loved by cats for its scent, but safe for other household pets. Its tough constitution makes it perfect for busy gardeners and those new to perennials.
