Machaeranthera Bigelovii commonly known as ‘Bigelow’s Aster’. Bigelow's Tansy Aster is a native biennial to short-lived perennial with deep violet to blue-white colored flowers. Leafy branched stems topped by flower heads with many narrow, bright reddish-lavender or purple rays surrounding 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.
