Erigeron speciosus is a widespread North American species of flowering plants in the family Asteraceae known by the common names aspen fleabane,[2] garden fleabane,[3] and showy fleabane.[4]
Description
E. speciosus is a perennial herb up which grows up to 100 centimetres (39 inches) 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.[4][5] Flowers bloom from June to October.[4][6]
The species is similar to E. subtrinervis, the stems and leaves of which are hairy.[6]
Etymology
The specific epithet speciosus means 'pretty'.[6]
Distribution and habitat
The species has been found in western Canada and the United States, from Alberta and British Columbia south as far as Arizona and New Mexico,[6][7] with some isolated populations in the Mexican state of Baja California. It grows in open coniferous forests.[6]
