The native Annual Fleabane is very common in our area. It prefers full or partial sun, moist to slightly dry conditions and is not fussy about soil characteristics. Typical habitats include disturbed areas of moist to slightly dry prairies, pastures and abandoned fields and areas along roadsides and railroads. This is an annual or biennial plant, up to 3½' tall, branching occasionally in the upper half to form flowering stems. The lower leaves are 3-5" long. Leaves along the upper stems are alternate, smaller in size, without petioles, and usually lance-shaped. Small clusters of daisy-like composite flowers occur toward the top (apex) of the plant, each about ½–¾" across with a yellow central disk surrounded by 50-120 white ray florets.
