Daisy fleabane

Erigeron strigosus is an annual or short-lived biennial herb of the Asteraceae family, growing 30 to 100 centimetres tall from a basal rosette, with one to several erect, sparingly branched, strigose-hairy stems. The basal leaves are oblanceolate to elliptic, 3 to 10 centimetres long, with entire or sparsely toothed margins and tapering bases, often withering by flowering, while the stem leaves are alternate, linear to lanceolate, 2 to 8 centimetres long, sessile or short-petioled, entire and bearing appressed, stiff hairs. The branching upper stems bear loose, open corymbs of small daisy-like flower heads, each 8 to 15 millimetres across, with 50 to 100 very narrow, thread-like white to faintly pink ray florets surrounding a small yellow disc of tubular florets. Flowering extends from late spring through summer. The fruits are tiny achenes with a double pappus of short scales and longer bristles. Native to most of North America, the species inhabits fields, prairies, roadsides and disturbed open ground.
