Nepeta 'Walker's Low' - 9cm pot
This is a fantastic medium-sized variety with aromatic grey-green foliage and masses of bright lavender-blue flowers over a long period beginning in late spring. It will flower all summer but I find cutting it back in mid-summer produces a really good flush of colour later in summer/early autumn. Fast growing and makes an excellent edging plant or filler for the garden. Loved by bees too. 40cm H x 45cm W. Full sun, drought tolerant. 9cm pot.
