Our protagonist, popularly known as piorno or serrano piorno, is a shrub native to the Mediterranean region. In Spain we find it above all in the Sierras de Guadarrama, Gredos, Paramera de Ávila, La Serrota, Sistema Ibérico, Montes de León and the Pyrenees.

It grows in dense bushes with a cushiony and highly branched appearance, with very thin stems, less than 0,5 cm thick, from which barely visible green leaves sprout. The flowers are yellow, aromatic (they emit a smell similar to honey), and they sprout in spring-summer.


It is used to make roofs in huts, as well as fuel for furnaces. Beds are also made for cattle with its branches.
