Ciliated German Pellitory

Ciliated German pellitory (Anacyclus ciliatus) is an annual or short-lived perennial herb in the family Asteraceae, native to the Mediterranean Basin. It produces prostrate to ascending stems bearing finely divided, feathery leaves and daisy-like flower heads with white ray florets and a yellow disc. The species grows in dry, open habitats such as rocky slopes, garrigue, abandoned fields, roadsides, and coastal scrub, preferring calcareous soils with low fertility and good drainage. Its distribution spans southern Europe, North Africa, and the Near East, encompassing the core of the Mediterranean climatic zone. Anacyclus ciliatus is classified as Least Concern, with widespread populations across its native range. The genus Anacyclus includes several species with similar morphology, and its taxonomy has been subject to revision. Like many Mediterranean annuals, ciliated German pellitory completes its life cycle during the cool, wet winter and spring months, producing abundant seed before the summer drought. It is a component of traditional Mediterranean dry grassland and rocky vegetation communities. Some Anacyclus species have been investigated for medicinal properties, particularly root extracts showing anti-inflammatory and analgesic activity. Conservation of Mediterranean garrigue and dry grassland habitats benefits this species alongside many other endemic plants of the region.
