Perennial of the Ranunculaceae family, native to southwestern Europe and the western Mediterranean basin, present in the Iberian Peninsula, southern France, Italy, and North Africa. It colonizes dry grasslands, rocky areas, and garrigues, generally between 300 and 1800 meters, on various substrates, often calcareous.
The plant forms an upright clump from 10 to 30 cm, immediately recognizable by its narrowly linear, grass-like leaves, glaucous to medium green, upright, which give it a very different appearance from most other European buttercups. It is this foliar characteristic that gives it its name.
The flowers are bright and shiny yellow, fairly large, borne on slender and branched stems that rise above the foliage. The petals are broadly oval, well spaced.
In its natural habitat, its flowering extends from April to June depending on the altitude. In cultivation, it blooms in spring and shows great ease on well-drained soil and in full sun.
It withstands summer drought well and is perfectly suited to rock gardens or crevice plantings. Its slender silhouette and unusual foliage make it easily identifiable among rock garden perennials.
