  • About this plant

    Nepeta 'Six Hills Giant' is a tall and fast-growing catmint variety, prized for its airy, sprawling habit and long-lasting lavender-blue flowers. Its aromatic, grey-green foliage forms a soft, mounded shape, making it perfect for spilling over paths, softening border edges, or adding movement to cottage-style plantings. Blooming from late spring to early autumn, this drought-tolerant and deer-resistant perennial thrives in full sun and well-drained soils. Its profuse flowering and ability to attract pollinators make it an excellent choice for wildlife-friendly gardens and low-maintenance planting schemes.
