Plants are dispatched in growing condition and may not be in full flower. If too tall to pack safely, we may cut them back — this helps them establish more quickly. Read our Mail Order FAQs.
Also known as Nepeta 'Longipes', 'Leeds Castle' is the accepted name for this distinctly upright catmint. Softly hairy, aromatic grey-green leaves form a tidy clump, and from late spring through to midsummer slender spires of pale lilac-blue flowers rise on light purple bracts, drawing bees and other pollinators in numbers.
Its upright habit makes it well suited to the middle of a sunny border, where it holds its own without flopping. Give it free-draining soil — chalk, sand, gravel, or loam all suit it well — and it will reward you with reliable, season-long colour. A useful note on aftercare: the stems are square and hollow, so resist the urge to cut back in autumn. Leave the plant to die back naturally; the hollow stems provide overwintering habitat for beneficial insects, and the structure looks handsome rimed with frost.

Plant Notes
-
Care Guide:
Grow in well-drained soil in full sun or partial shade. After the first flush of flowers, cut back to keep the plant compact and encourage another display. Leave the old stems and foliage over winter to provide hibernation shelter for ladybirds, then cut back hard in spring as new growth emerges.
Lift and divide large, established clumps in spring or autumn to rejuvenate them. To raise new plants, take softwood cuttings in early summer. -
Good to Know:
Pollinator-friendly. Drought-tolerant once established. Aromatic foliage.
Some Nepeta attract cats, particularly catnip (Nepeta cataria). They may roll among the stems and chew the leaves, so young plants may need protection from their attention. -
