About Centaurea sphaerocephala
Centaurea sphaerocephala, or Round-headed Centaury, is a robust perennial herb, valued for its large and distinctive spherical purple-pink flower heads. Its summer blooms are a magnet for pollinators and add a wild, elegant touch to gravel gardens, flower beds, or naturalized meadows.
Native range
Mediterranean region, especially Southern Europe and North Africa
Care tips
It requires full sun for abundant flowering and optimal development. Drought-tolerant once established, it appreciates moderate watering during dry spells; excessive moisture can be detrimental. It prefers well-drained soils, even poor or calcareous ones. A common mistake is overwatering, which can lead to root rot, so ensure the substrate dries out between waterings.
