perostos

Perostos is a genus of flowering plants in the family Asteraceae, commonly known as the daisy family. The plants in this genus are native to the Mediterranean region and the Middle East. They are typically herbaceous perennials with a rosette of basal leaves and erect, slender stems that bear solitary flower heads. The flower heads are composed of ray florets and disc florets, characteristic of the Asteraceae family.

Species within the Perostos genus are generally small to medium-sized plants, often found in dry, rocky, or sandy habitats. Their appearance can vary, but many are recognized by their somewhat woolly or hairy foliage, which helps them conserve water in arid environments. The flowers are usually white or pale yellow, with the ray florets often being longer than the disc florets.

Reproduction in Perostos is primarily through seeds, which are dispersed by wind or animals. The plants have a relatively short flowering season, typically occurring in the spring or early summer. Due to their adaptation to challenging conditions, they are often considered hardy and drought-tolerant. While not widely cultivated, some species may be found in specialized rock gardens or xeriscapes. The exact taxonomic classification and number of species within Perostos can sometimes be subject to revision by botanists.
