Nepeta 'Hill Grounds' forms neat clumps of grey green foliage topped by thick heads of rich violet and purple flowers from June to August, with occasional rebloom into October. Floriferous and aromatic, its perfect for softening border edges and attracting pollinators.

Named by Janet Cropley in her Hill Grounds garden, this variety stands out for its intensity of colour and well-behaved form. Height to 55cm.
