Erigeron speciosus
Erigeron speciosus is a widespread North American species of flowering plants in the daisy family known by the common names aspen fleabane, garden fleabane, and showy fleabane. It has been found in western Canada and the United States, from Alberta and British Columbia south as far as Arizona and New Mexico, with some isolated populations in the state of Baja California in Mexico.
Erigeron speciosus grows on in prairies and in open coniferous forests. It is a perennial herb up to 100 cm tall, producing underground rhizomes and a woody caudex. The inflorescence generally contains 2-20 flower heads per stem. Each head contains 75–150 white, lavender or blue ray florets surrounding many yellow disc florets.
