100% Peat Free Pollinator Friendly RHS Award of Garden Merit

Nepeta cyanea stands out in the genus for its unusually large flowers. From mid to late summer, tall, plump spikes carry deep purplish-blue blooms arranged in whorls around gently arching stems, rising above bushy clumps of mid-green, scented foliage. The slightly informal habit makes it a natural choice for more relaxed planting schemes — a gravel garden, a coastal border, or a naturalistic meadow-style planting — and its nectar-rich flowers are a reliable draw for bees and butterflies throughout the season.

Like many plants of Mediterranean origin, it thrives in free-draining soil in full sun and, once established, becomes genuinely drought-tolerant — a low-maintenance asset in a dry summer.

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.
