Plant description
Purple-eyed flowerheads, each with a ruff of long white florets, form throughout the summer above the clumps of grey-green foliage, creating easy-going groundcover that will thrive in a sunny spot. It's ideal for a more naturalised setting - and the bees and butterflies love it too.

How to care for Centaurea montana Purple Heart:
Stake with brushwood or bamboo canes before the flowers appear. Cut back to the ground after flowering and you may get a second flush of flowers. Lift and divide large clumps every three years in spring.
Please note:
This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.
