Rough Fleabane, Lesser Daisy Fleabane, Daisy Fleabane
Daisy fleabane is a North American native, a member of the sprawling aster family.
Identification: These plants have an erect stem that has many fine white hairs, and are 12-36" (30-91 cm) tall. The hairs are antrorse strigose, botanist talk for “lying down against the stem, in the upward direction.” Leaves are mostly narrow, attached directly to the stem but not wrapped around it. Most leaves lack teeth. Lower leaves are fatter in the center. Flowers are white, about ½" (1.5 cm) in diameter, with 50-100 petals and a central yellow disk. They flower from May to September.
Edibility: Not edible. May cause a contact dermatitis.
