Description
Centaurea montana is a stunning meadow and woodland plant which has violet blue flowers in the early summer. They are borne over the grey-green leaves and show off its spidery flower heads and its eye-catching purple tones. They are perfect in sunny borders and in gravel gardens. The butterflies and bees love Centaurea montana due to its nectar rich blooms too. As flowers begin to fade, deadhead those which will help prolong the flowering. Height 45cm (18”) and spread 60cm (24”).

How to Grow
Grow Centaurea in borders in full sun. Perennial Cornflowers are drought tolerant once established and will happily tolerate almost any soil, except those that are excessively waterlogged.
More Info
Water Centaurea plants regularly until fully established. In autumn, cut back old stems to just above ground level to make way for new growth in the spring.
