Centaurea montana - 2026

Centaurea montana, commonly called perennial cornflower or mountain bluet, is a hardy, clump-forming perennial admired for its distinctive fringed blue flowers. Blooming from late spring into early summer, the vibrant, star-like flower heads with purple centres rise above mounds of grey-green, lance-shaped leaves, creating a striking display. Loved by bees, butterflies, and other pollinators, it is a valuable plant for wildlife-friendly gardens, while its long flowering season brings reliable colour to borders and cottage-style plantings.

Thriving in full sun to partial shade with well-drained soil, Centaurea montana is easy to grow and very resilient, tolerating a wide range of conditions. Cutting back after the first flush of flowers often encourages a second wave of blooms later in the season. Hardy and robust, it spreads steadily to form attractive clumps, and spent stems can be removed to keep the plant tidy. Its combination of ornamental charm, ecological value, and low maintenance makes it a versatile choice for mixed borders and naturalistic settings.
