Nepeta Cats Pajamas2litre

Indigo blue flowers on dark stems from summer onwards, over small aromatic leaves that form a neat ball. Bees love it, and so do cats, which will happily roll around in it. The foliage dies back in autumn and returns in spring. Great for pots or the front of a border.

Good to know: 35 x 50cm. Full sun, well-drained soil. Fully hardy. Cut it back after flowering for a second flush.
