Mountain bluet

Centaurea montana

''Centaurea montana'' is a species of ''Centaurea'' endemic to Europe. It is widespread and common in the more southerly mountain ranges of Europe, but is rarer in the north. It escapes from gardens readily, and has thereby become established in the British Isles, Scandinavia and North America.

Appearance

''C. montana'' may be distinguished from other ''Centaurea'' species in the region by its usually entire leaves, and the blue-purple colour of the outermost ray florets. It may be distinguished from the cornflower, ''C. cyanus'', by having a single flower heads, and by its being perennial, whereas the cornflower has many flower heads and is annual. The closely related ''C. triumfettii'' has more narrowly winged stems, narrower leaves and grows in rockier areas.
