Erigeron speciosus (Lindl.) DC.
Aspen fleabane, Showy fleabane
Asteraceae (Aster Family)
USDA Symbol: ersp4
Clusters of leafy stems,1/2-2 1/2 ft. tall, rise from the woody rootstock of this perennial. Each stem bears several showy, nearly 2 in. wide flower heads with from 70-150 blue, or rarely white, narrow rays. A leafy stem branches near the top into leafless stalks, each with one flower head at the end, with many narrow pink, lavender or white rays surrounding a yellow disk. The disk flowers are yellow-orange. The lower leaves of this plant tend to fall off as the season advances.
This Erigeron has one of the showiest heads, reflected in the species name, speciosus, which means pretty. The similar Hairy Showy Daisy (E. subtrinervis) has spreading hairs over most of the stem and leaves.
