(a.k.a. aster, Aster spinosus, buena mujer, spiny chloracantha)

White ray flowers and yellow disk

Devilweed is a member of the aster family, native to the southwestern United States. Like a number of other asters, it has many-branched stems and flowers that actually comprise ray flowers (what look like standard petals) and disk flowers (tiny flowers in the center of the inflorescence). Devilweed has white ray flowers and yellow disk flowers. It can grow to be several (4 to 5, or even 6) feet tall. It grows on a variety of sites from wet areas to semi-arid soils.
