About Centaurea alba
Centaurea alba, also known as Centaurée blanche, is a perennial herbaceous plant from the Asteraceae family, recognized for its delicate white flowers often with pink or purple-tinged centers. It forms compact clumps of grayish-green foliage, perfect for rock gardens, sunny borders, or as part of a wild and naturalistic garden where it adds an ethereal touch.
Native range
Iberian Peninsula and North Africa
Care tips
This Centaurea thrives in full sun in well-drained soil, preferably calcareous and poor, which helps prevent excessive legginess. Watering should be moderate, allowing the substrate to dry out between waterings, as it is drought-tolerant once established. A common mistake is over-fertilization or overly rich soils, which can lead to leggy growth and less flowering. Deadheading spent blooms encourages prolonged flowering.
