Machaeranthera bigelovii (A. Gray) Greene
Bigelow's Tansyaster, Sticky Aster
Asteraceae (Aster Family)
Synonym(s): Dieteria bigelovii
USDA Symbol: MABI
Leafy branched stems topped by flower heads with many narrow, bright reddish-lavender or purple rays surrounding a yellow central disk.
These wildflowers of late summer often color entire banks and roadsides with vibrant purple. In the afternoon, as flower heads become shaded, the rays fold upward in the "sleep position." Sticky Aster resembles true asters (Aster) but has spiny or divided leaves.
