Catmint

This attractive perennial looks wonderful when covered in flower from early summer. The pale, lavender-blue flowers perfectly complement the hairy, scalloped and wrinkled, silvery, blue-green leaves. From afar the flowers appear as a haze of blue. Nepeta has a rather lax form and will spread itself to cover its allotted space. Plant it at the front of the border, edging a path, so that when you brush past it you will catch the full scent from its aromatic leaves. Cats love Nepeta and tend to roll around on it, flattening the plant even more. Divide it in spring or in autumn. The Royal Horticultural Society have given it their prestigious Award of Garden Merit.

Looks good with:

Allium cristophii
Zinnia elegans 'Envy'
