Perennial of the Asteraceae family, native to the Mediterranean region, from Portugal to Greece and North Africa. It grows in open scrublands, dry grasslands, roadsides, and sunny rocky terrains, on well-drained calcareous or siliceous substrates, mainly at low and medium altitudes.

It forms a bushy clump 20 to 40 cm in height, with soft, gray-green, slightly hairy, pinnatifid to lobed leaves, arranged in a basal rosette and along the stems. The foliage is supple and somewhat grayish in appearance, contrasting with the brightness of the flowers.

The flower heads are large, solitary at the top of branched stems, entirely composed of ligulate florets with a truncated and finely toothed tip, of a very pale sulfur yellow, almost lemon, turning to cream as they age. The center of the flower head, darker at maturity, creates a subtle contrast with the peripheral ligules. A detail worth noting on the flower heads in the process of opening: the external ligules then bear bright purple-violet spots on a cream background, while the internal ligules, still tightly coiled around the dark center, give the flower head an architecture reminiscent of a sea anemone's rosette. This bicolored characteristic fades and disappears on fully bloomed flowers.

In its natural habitat, its flowering extends from April to June. In cultivation, it can bloom intermittently in summer if conditions are favorable.

It requires full sun, very well-drained soil, poor to moderately fertile, and tolerates summer drought well once established. Its hardiness is adequate in regions with mild winters, but it can suffer from prolonged and wet cold.
