Circulara

Circulara is a genus of flowering plants in the family Asteraceae, native to the Mediterranean region. The genus is characterized by its annual or perennial herbs, with simple or lobed leaves and yellow, daisy-like flowers. The flowers are typically arranged in a flat-topped inflorescence, with a central disc surrounded by ray florets.

Circulara is a small genus, with only four recognized species. The most well-known species is Circulara americana, which is native to the southwestern United States and northern Mexico. This species is often cultivated for its attractive flowers and is known for its ability to tolerate a wide range of soil conditions.

The other three species in the genus are Circulara bracteata, Circulara glabra, and Circulara pauciflora. These species are less commonly cultivated but are also valued for their ornamental qualities. Circulara bracteata is native to the Mediterranean region, while Circulara glabra and Circulara pauciflora are native to the Canary Islands.

Circulara plants are relatively easy to grow and can be propagated from seed or division. They prefer well-drained soil and full sun to partial shade. The flowers are typically pollinated by bees and other insects, and the seeds are dispersed by wind.

Circulara is a genus of ornamental plants that is valued for its attractive flowers and ability to tolerate a wide range of growing conditions. While the genus is small, it includes several species that are popular in gardens and landscapes.
