Erinus

Erinus is a genus of flowering plants in the family Plantaginaceae. The genus currently contains two recognized species, both of which are native to Europe. Erinus alpinus, commonly known as alpine erinus or fairy's thimble, is the more widespread species. It is a small, herbaceous perennial that typically grows to a height of 10-20 cm. Its leaves are basal and lance-shaped, and its flowers are usually pink or lilac, with five petals. Erinus alpinus is found in rocky, alpine habitats, often on limestone. The second species, Erinus humilis, is a more diminutive plant found in the Pyrenees mountains.

The genus Erinus was first described by Carl Linnaeus in 1753. The name Erinus is derived from the Greek word "erinus," meaning "wild," likely referring to the plant's natural habitat. Erinus species are sometimes cultivated as ornamental plants, particularly Erinus alpinus, for their attractive flowers and hardiness. They prefer well-drained soil and a sunny position. Propagation is typically done by seed or division. The distribution of Erinus plants is primarily in mountainous regions of Europe, with Erinus alpinus found across the Alps, Pyrenees, and other European mountain ranges, while Erinus humilis is more restricted to the Pyrenees.
