Centaurea montana


Stunning pinwheel flowers, with intense blue fringes and deep purple centres, are a real eye catcher on Centaurea montana, the Perennial Cornflower.

Vivid blue pinwheel flowers 

The intensely blue flowers are large, up to 7.5cm (3in) across, so they make a big impression for such a small neat plant. 
(See the “Growing” section below for plant details, how and where to grow)

Suits smaller gardens 

Centaurea montana delivers value year round for small gardens, with vividly coloured, long blooming flowers, above a neat silver-grey foliage clump

An ideal garden edger

It is also an ideal edging plant because of the the tight, low growth habit, and wonderful colour contrast of blue flowers on grey foliage.
And it certainly stands out against all the other green plants.
So I use it as a silver and blue edge for a path amongst apricot roses.
Centaurea montana, Perennial Cornflower, also makes a pretty feature in a pot year round.

Attractive foliage all year

Blue-silver-grey, lance-shaped leaves are attractive and tidy year round too. 

Hardy, easy & low maintenance

Centaurea montana is an unfussy, easy to grow, and frost hardy plant.
Happily it requires little to no maintenance once established. 

Perfect under deciduous trees, or part shade

Centaurea montana prefers a little shade and dappled sunlight, or shade for part of the day, particularly in hot areas.
However it will also thrive in full sun where the soil is retentive, or the district cooler.
So it prefers deciduous shade rather than evergreen shade, where it can enjoy the sun during the cooler months when the overhead canopy has fallen.
This beauty can tolerate drought but cannot tolerate waterlogged conditions.

Other garden benefits

– Beneficial for wildlife: Bees and other beneficial pollinators are always very busy working the flowers for pollen and nectar.
– Care: Easy, Low care plant requiring very little maintenance. You can tidy off spent flower stems if you are looking for something to do, but it is not essential. Otherwise they are care free.
Water: Normal average garden water is sufficient, and this is a hardy plant that can withstand variations and more difficult periods of heat and dry.
– Deer & Rabbit resistant: Nibbling pests do not enjoy the texture of Centaurea foliage. It is even listed by Washington State University as a deer resistant plant.
Fragrance: Sadly none, but other good qualities make you forgive this misdemeanor. 
– Origin: Centaurea montana is native to Europe, particularly in France and Italy. So the Mediterranean style climate of southern Australia suits it perfectly.
