Rough fleabane, lesser daisy fleabane, daisy fleabane, prairie fleabane
Daisy fleabane is a North American native, a member of the sprawling aster family.
Plants: These plants have an erect stem that has many fine white hairs, and are 1–3′ (30–91 cm) tall. The hairs are antrorse strigose, botanist talk for “lying down against the stem, in the upward direction.”
Leaves: Mostly narrow, attached directly to the stem but not clasping (wrapped around it). Most leaves lack teeth. Lower leaves are fatter in the center.
Flowers: A loose, spindly array of branching stems can support as many as 200 flowers. Flowers are white, about ⅛″ (5 mm) in diameter, with 40-100 ray florets and a central yellow disk with numerous disc florets. They flower from May to September.
Fruits: Light brown achenes about 1/32″ (1 mm) long have small tufts of hair, and are distributed in part by wind.
Habitats: Dry prairies, well-lit woods and fields, disturbed ground, roadsides.
Edibility: Not edible. May cause a contact dermatitis.
