Phagnalon

Phagnalon is a genus of flowering plants in the family Asteraceae. These plants are commonly known as sandworts, though this name is also shared by other genera. Phagnalon species are typically found in dry, arid, or semi-arid regions, with a distribution extending across the Mediterranean basin, the Middle East, and parts of North Africa. They are often found in sandy soils, gravelly areas, and on rocky slopes.

The plants are generally small, herbaceous or subshrubby, with a distinctive silvery-grey foliage due to a dense covering of hairs. This adaptation helps to reduce water loss and protect the plant from intense sunlight. The leaves are usually narrow and linear. The flower heads of Phagnalon are composite, characteristic of the Asteraceae family, and typically consist of numerous small florets. The outer florets are often sterile and petal-like, while the inner florets are fertile. The overall appearance of the flower heads can vary, but they are often yellowish or whitish.

Phagnalon species have been used in traditional medicine in some regions for various ailments, although scientific evidence for their efficacy is often limited. Their hardy nature and adaptation to harsh environments make them resilient members of their ecosystems. The genus Phagnalon contains several species, with some of the more well-known examples including Phagnalon saxatile and Phagnalon rupestre.
