polycrest

Polycrest, also known as Polycrestum, is a genus of flowering plants belonging to the family Asteraceae. The genus is native to the Mediterranean region and is characterized by its unique inflorescence, which consists of a central disk surrounded by ray florets. The disk florets are typically yellow or orange, while the ray florets are white or pink. Polycrest species are often used in landscaping and gardening due to their attractive flowers and low maintenance requirements.

The genus Polycrestum was first described by Carl Linnaeus in 1753. It includes several species, with the most well-known being Polycrestum aureum, commonly known as the golden polycrest. This species is native to the Mediterranean region and is widely cultivated for its bright yellow flowers and attractive foliage. Other species in the genus include Polycrestum orientale, which is native to the Middle East, and Polycrestum glabrum, which is native to the Canary Islands.

Polycrest plants are herbaceous perennials that typically grow to a height of 30-60 cm. They have a basal rosette of leaves and produce a single stem with a terminal inflorescence. The leaves are typically ovate or lanceolate, with serrated margins. The flowers are arranged in a disk surrounded by ray florets, and the plant produces seeds in a dry, indehiscent fruit called a cypsela.

Polycrest species are often used in rock gardens and other dry, sunny locations. They are relatively low maintenance and can tolerate a wide range of soil types. However, they do require well-drained soil and regular watering during the growing season. With proper care, Polycrest plants can produce attractive flowers for several years.
