Nepeta x faassenii Six Hills Giant (Catmint)

Common Name:
Catmint ‘Six Hills Giant’

Description:
Nepeta x faassenii ‘Six Hills Giant’ is a vigorous and long-flowering perennial prized for its soft, billowing habit and masses of lavender-blue flower spikes that create a hazy, cottage garden effect. This hardy variety features aromatic grey-green foliage that forms a dense, spreading mound, releasing a pleasant scent when brushed against. From late spring through to early autumn, it produces abundant blooms that are highly attractive to bees and other beneficial pollinators. Exceptionally well-suited to Melbourne’s climate, it thrives in full sun with well-drained soil and demonstrates excellent drought tolerance once established, making it a reliable choice for low-maintenance landscapes. Regular trimming after the first flush of flowers encourages repeat blooming and helps maintain a tidy shape. Ideal for borders, edging, and informal plantings, it pairs beautifully with roses and other perennials.
