Other Common Names:
Rough fleabane is a summer annual that flowers from April to October. It is often found on roadsides and in old fields.
Leaves are linear-lanceolate and pointed at the tip. The lower ones tend to be toothed, and the higher ones may be hairy. They are alternate in arrangement and are non-clasping.
Rough fleabane is identified by its flowers and linear leaves that are larger near the base. It is distinguished by being shorter in height and having fewer leaves than annual fleabane.
