Centaurea montana-Mountain Bluet, Perennial Bachelor Button, Cornflower

Centaurea montana is best propagated in the spring but the fall is also acceptable by cutting lose the rooted stolons and transplanting into another area of the garden bed. Centaurea montana can become invasive if planted in good rich soil so opt for poor alkaline but well drained soil in full to mostly sunny conditions, but will not tolerate humidity nor wet feet in winter. It reaches a height of 2-3' and blooms most of the growing season in wide ranging colors: blue, mauve, pink, crimson, white and yellow and may need to be staked in windy locations and can be cut back after blooming to refreshen the foliage to re-bloom and is evergreen, drought tolerant and deer resistant.
