About Centaurea exarata
Centaurea exarata, commonly known as Silver Centaury, is a perennial or biennial plant native to the Mediterranean basin. It is distinguished by its silvery, finely divided, and velvety foliage, forming compact mounds. It is ideal for rockeries, dry gardens, and borders, providing a very attractive color and texture contrast.
Native range
Balkan Peninsula and Turkey
Care tips
It requires full sun to maintain its intense silver color and optimal flowering. Watering should be moderate to sparse, allowing the substrate to dry out completely between waterings, as it is very drought-tolerant. It prefers well-drained soils, even poor and calcareous ones, and a common mistake to avoid is overwatering, which can lead to root rot.
