Nepeta ‘Six Hills Giant’
This is the catmint featured in the English coffee table gardening books. Sadly a second rate plant is still being sold as this in Australia. We grow it in front of a stone wall in a bed that is never watered. Its lovely grey leaves set off lax sprays of ethereal hazy lavender blue flowers. We cut it to the ground after Christmas and again in late autumn or winter. This cutting back keeps it looking fresh and flowering for 6 to 7 months. 50cm x 85cm.
