Common Knapweed
€6.95
Common Knapweed (Centaurea nigra) is offered here as a small-medium potted plant. A hardy perennial wildflower forming dense clumps of narrow, lance-shaped leaves, it grows to 30-90 cm and produces thistle-like purple flower heads from late spring right through to early autumn. This long flowering season makes it one of the most valuable native nectar plants for bees, butterflies and hoverflies across the warmer months. Undemanding and tolerant of poorer soils, it is a mainstay of Irish wildflower meadows and pollinator strips. A low-maintenance choice for naturalistic borders, meadow plantings and wildlife gardens throughout Ireland and the UK.

Growing Instructions
Plant in full sun or partial shade in well-drained soil, ideally enriched with compost. Water regularly for the first few weeks to help roots establish; once settled, the plant is drought-tolerant and needs little further attention. Mulch lightly during establishment to retain moisture. Deadhead spent flowers to prolong blooming, or leave some heads to set seed for finches and other wildlife. Common Knapweed returns reliably each year, gradually building a strong nectar source for pollinators in a meadow or border setting.
