Centaurea prolongoi

The crop prefers calcareous substrates and stony soils, which are typical for arid Mediterranean regions. The plant exhibits high adaptability to drought-prone environments, reflecting its evolutionary development in semi-desert zones.

Successful cultivation requires abundant sunlight and excellent root system aeration. Excessive moisture and heavy clay soils can lead to root rot, making high-quality drainage a critical factor for long-term survival.

Botanically, the plant is distinguished by silvery-grey foliage pubescence, which helps reflect solar radiation and reduce transpiration during hot spells. The flower heads exhibit a specific morphology typical of the Centaurea genus, with tightly appressed involucral bracts.

In terms of practical use, this species is primarily valued as an ornamental element for rock gardens and xeriscapes, as well as an object of study for biodiversity conservation efforts concerning the rare flora of the Iberian Peninsula.
