Nepeta Purrsian Blue, also has faassenii tucked into its name (resembling a bad scrabble hand), but this superb plant is actually a variety of the humble Catmint. However, plant this obliging perennial in drifts along a walkway or underneath roses, and the effect of blue clouds is very far from humble.

Deer, rabbit and drought tolerant, N. Purrsian Blue will form lovely, rounded clumps of grey/green leaves, from which emerge a profusion of delicate blue flower spikes. A classic and easy-going plant for cottage or informal planting, the foliage is pleasingly aromatic if you brush past it on a footpath or in a container. Also important is the fact that it attracts local pollinators to your garden for months on end.
