Centaurea montana--Mountain Bluet
Hardiness Zones: 3 to 8
Height: 24 in Spread: 18 in
Type: herbaceous perennial
Flowers: Blue, white, pink (Vis. 1).
Comments: These are easy to grow plants that can spread
rapidly. Provide some support to keep plants from
flopping over and cut them back after they flower. The
plant may be a suitable choice for alkaline soils.
Shearing the plants after the first flush of bloom will
encourage another round of flowering.
Propagation: The plants are propagated by seed or
division with division preferred. Cuttings may be started
in September. Division is done in the spring. Early
blooming Centaurea are divided in autumn and late bloomers
in spring. The seed germinates in 3 to 4 weeks at 65 to
70 degrees and is usually planted directly into the
garden. Basal growths may be rooted in June and July.
Cultivars:
'Blue' - Blue flowers with fringed margins.
References for Cultivars: Walters Gardens 1999, Ray
