Nepeta faassenii 'Six Hills Giant' - 2026

Nepeta faassenii 'Six Hills Giant' is a tall, vigorous perennial valued for its abundant display of lavender-blue flowers and aromatic foliage. It forms a large, spreading clump of grey-green leaves that smell delightful when brushed. The flower spikes appear in late spring and continue through summer, attracting bees, butterflies and other pollinators. Its impressive stature adds architectural interest in the garden, particularly in sunny borders or as a backdrop to smaller plants.

This cultivar thrives in well-drained soil, preferring full sun but tolerating a little partial shade. Once established, it is relatively drought-tolerant although flowering is best in good light and soil. Regular trimming after the first flush of flowering helps maintain shape and encourages another round of blooms. Its robust habit combined with long flowering makes ‘Six Hills Giant’ a great choice for low-maintenance yet striking garden schemes.
