Nepeta 'Six Hills Giant', 5LThe vigorous perennial, Nepeta Six Hills Giant is a reliable form of the humble catmint, with aromatic silvery green foliage, and, from mid summer, spikes of small, violet flowers. Forming a low dense mound in the border, or edging a pathway, it makes a great alternative to lavender, its flowers also a magnet for bees. Nepeta Six Hills Giant is a recipient of the RHS AGM (Award of Garden Merit), for all round excellence.
