dorea

Dorea is a genus of flowering plants in the family Asteraceae, commonly known as asters. The genus was described by Constantine Samuel Rafinesque in 1837. Plants in this genus are native to North America and are characterized by their daisy-like flowers, typically with ray florets of white, pink, or purple surrounding a yellow or brown center. The leaves are usually simple and alternate, and the plants are generally herbaceous perennials. Dorea species are often found in grasslands, meadows, and open woodlands.

One notable species within the genus is Dorea multiflora, also known as multiple-flowered aster. This species is distinguished by its abundant flowering. The genus Dorea is closely related to other genera within the Asteraceae family, such as Symphyotrichum and Aster, and taxonomic classifications have sometimes varied regarding the placement of certain species. Research into the genetic relationships and evolutionary history of these genera continues to refine our understanding of their classification. Dorea plants play a role in their ecosystems, providing nectar and pollen for pollinators like bees and butterflies, and their seeds can be a food source for birds. Their ornamental value has also led to their cultivation in gardens.
