Centaureas "From Turkey" and montana Alba in May.


Some Centaurea love hot, dry conditions, but most will thrive in any normal garden soil. If your soil is claggy and poorly drained then add plenty of grit to the soil when planting.

Most will benefit from the sunniest position you can find, but in our experience many (e.g. montana) will grow well in light shade.

Care and Maintenance:

Most Centaurea will spread by underground runners so they can easily be dug up and moved to a new location. Be aware though that they can regrow from root left in the soil.

Whilst they are drought tolerant they will benefit from a good soaking from time to time. Some will become dormant in hot dry spells - don't be alarmed they will resprout when the rain returns.

Cutting back the stems to new shoots after flowering promotes repeat blooming throughout the season in most types (not macrocephala and glastifolia)- don't be afraid to cut them back hard. This is also the treatment if mildew is a problem - the new leaves will be fresh and healthy provided you clear away all infected leaves.

Some species (e.g. macrocephala, glastifolia) have very attractive seed heads that last through the winter. The seeds are loved by birds and small mammals (especially voles). Cut back these stems in early spring.


Division is easy with most species - simply dig up and pull apart. Large numbers of plants can be grown from root cuttings taken in winter. Most species are easily raised from seed and do not seem to hybridise. Seed is best sown fresh, straight after harvesting. If seed heads are left on the plants over winter, seeds will often germinate inside the heads. These can be carefully teased out and pricked out into trays or modules.

Using Centaurea:

Centaurea are ideal plants with species suitable for the border, scree garden or rock garden. The tall species are largely self supporting (the exception being perhaps dealbata which can flop a bit unless supported with a few twigs) and compete well with other plants, holding their own in the bed.

Try planting the tall yellow glastifolia with Helenium, its branched stems and round heads contrast well with the latter's flat heads of flower.

Many Centaurea are meadow flowers (e.g. jacea, phrygia, nigra) and look great in a cottage garden setting.

Remember that the buds of Centaurea can provide interest and contrast as well as the flowers: glastifolia has silver buds, macrocephala bronze and montana types have jewel-like black and emerald buds.

Centaurea Jordy

Unique deep maroon flowers on bushy plants about 2ft - 2ft 6in tall. The silver-green leaves are like those of Centaurea montana varieties but the plants are less spreading than most of these.

It is apparently a hybrid between montana and jacea.

You may find this plant under the names Jody and Jonty as well.
