Small annual or biennial asteraceae endemic to Sicily, confined to the volcanic slopes of Etna and a few neighboring localities on basaltic and lava substrates, where it colonizes loose soils, volcanic screes, and pioneer zones with sparse vegetation, from mid-altitude levels to subvolcanic summit areas swept by winds.
Graceful and elegant morphology despite its modest size: plant 10 to 30 cm tall, with slender stems branched from the base, bearing finely divided foliage, pinnatisect with narrow and linear segments, of a slightly pubescent grayish green. Solitary capitula at the top of the branches, composed of a bright yellow central disc and radiating white ligules, following the classic floral pattern of the genus, of moderate diameter but with very pleasant clarity and freshness. Conical receptacle bearing characteristic scales of the genus. Small achenes, without pappus.
A plant for collectors and specialists, rarely encountered in cultivation outside botanical gardens and enthusiasts of insular Mediterranean flora. Its narrow endemism and adaptation to particular volcanic conditions — very draining, poor substrates, subject to extreme temperatures and intense sunlight — make it a delicate subject to maintain sustainably in cultivation, requiring perfect drainage, a very sunny location, and protection against any stagnant moisture. Considerable scientific and heritage interest as a witness to the pioneer flora of active Mediterranean volcanoes.
