In the garden

Nepeta 'Six Hills Giant' is a perennial in the Nepeta group, valued primarily for its scented leaves and an extended display of flowers through the summer months. Flowering runs from June to September, so it supplies colour and texture across much of the main gardening season while the foliage remains a notable feature. Place plants in full sun or partial shade and choose a well-drained soil with a neutral to alkaline pH; the cultivar will tolerate both dry and moist situations and performs in sheltered or more exposed sites. Its hardiness rating is H5 (hardy), meaning it is capable of surviving the majority of UK winter conditions without special protection. Use Nepeta 'Six Hills Giant' where its long flowering season and foliage scent are most useful: along mixed borders, as a ground cover to soften paths and edges, or within herb beds. The plant's summer bloom period makes it particularly suitable for filling the interval between early-summer and late-summer perennials in mixed plantings, and its aromatic leaves provide sensory interest even when not in flower.
