Pterocephalus perennis ssp perennis

Perennial of the Caprifoliaceae family (formerly Dipsacaceae), native to Greece, where it is mainly known from the mountainous regions of the center and north of the country, notably in Macedonia and Thessaly. It grows on rocky grounds, stony slopes, and limestone rock crevices, generally between 1,200 and 2,200 meters of altitude.

It forms spreading and semi-woody clumps at the base, 8 to 15 cm in height when in bloom. The foliage is crenate to lobed, a grayish green, distinctly tomentose, with well-marked margins. Compared to subsp. bellidifolius, the leaves are generally more dissected and grayer. After flowering, the faded capitula transform into spherical and feathery fruiting bodies.

The capitula are borne on slender erect peduncles and are distinguished by their particularly pale hue, very washed-out lilac pink, almost rosy white, with flowers of gradually differentiated size from the periphery to the center, giving the capitulum a radiant and regular structure. In its natural habitat, its flowering extends from June to August depending on the altitude.

In cultivation, it requires full sun, a well-drained soil preferably calcareous and stony, and protection against excessive winter humidity. It finds its place in rock gardens or alpine troughs.
