A Caucasian endemic, with beautiful pinnate greyish leaves, which is widely used as a groundcover in the dry Mediterranean gardens of the French Riviera. Once established, it is happy in any soil that isn’t bog-like. A definite weed suppressor. Centaurea bella’s foliage grows about 10cm tall and the branching flower stems, carrying the beautifully shaped amethyst-pink flowers, are 30cm tall. Allow 30cm to 40 cm width.
