Ballota nigra (Black horehound) 9 cm Pot

Growth habit & appearance: Ballota nigra, or Black Horehound, forms a bushy, softly downy perennial with deeply veined grey-green leaves that release a distinctive earthy aroma when touched. Its square stems carry tiered whorls of muted purple to pinkish flowers, typical of the Lamiaceae family, which attract bees and other small pollinators. Although not a showy plant, its rugged texture and herbal scent give it a characteristic, old-world medicinal charm.

Growing conditions: This species is fully hardy across Ireland and grows reliably in full sun, though it copes well with light shade. Native to Ireland and thrives in most well-drained positions. Supplied in a 9 cm pot, it can be planted out directly and will tolerate cooler weather without issue. Once established, it forms a resilient clump that returns each year.

Traditional & herbal uses: Black Horehound has a long history of use for easing nausea, motion sickness, and digestive unease, and has been associated with traditional support for insomnia and symptoms of Ménière’s disease. Only the aerial parts are harvested, ideally before flowering for highest potency.

Maintenance & harvesting: Harvest young leaves before flowering to maintain leaf quality and encourage fresh regrowth. If plants become congested, divide the clumps to keep them vigorous. Prune lightly after flowering to maintain a tidy structure. Black Horehound prefers not to be overfed; moderate fertility and free drainage produce far better growth and flavour.
