Daisy fleabane is a member of the Aster (Asteraceae) family. It is an annual plant with slender, erect stems up to 2 1/2 feet tall. The flowers resemble miniature daisies. Flower heads are on individual branches in a spreading cluster, with each head up to 1 inch wide. The heads have a fringe of more than 40 white, threadlike ray flowers, about 1/4 inch long, surrounding a circle of densely packed, yellow disk flowers. Daisy fleabane blooms mid-spring to early fall and is common throughout the tallgrass region in mesic to dry prairies, old fields, pastures, and other sites. It is considered to be a weed in disturbed sites over most of the U.S. and southern Canada.
