Orchidastrum

Orchidastrum is a genus of flowering plants in the family Asteraceae, commonly known as the prickly poppies. The genus was established by Carl Linnaeus in 1753. Species within Orchidastrum are native to the Americas.

The plants are characterized by their herbaceous perennial nature, often with deeply lobed or divided leaves. The flowers are typically large and showy, with multiple petals that can be white, yellow, or pink. They bloom during the summer months and are pollinated by insects. The fruit is a capsule containing numerous small seeds.

Orchidastrum species are found in a variety of habitats, including grasslands, open woodlands, and disturbed areas. Some species are known for their medicinal properties and have been used in traditional folk medicine. However, some species can be invasive in certain regions, posing a threat to native flora. Conservation efforts are in place for some of the rarer species.

The taxonomy of Orchidastrum has been subject to revision, with some species previously classified under other genera now placed within this group. Further research continues to clarify the relationships between different species and their evolutionary history. The genus is of interest to botanists due to its unique floral morphology and ecological adaptations.
