Daisy FleabaneErigeron strigosus Muhl. ex Willd. Muhl. ex Willd.
The yellow and white flowers of this annual (or sometimes biennial) plant are not fragrant. They make an attractive addition to prairie gardens, attracting butterflies and bees in spring and early summer when there aren’t a lot of other plants in flower. Because they can self-fertilize, cross-pollination is not necessary for plants to set fertile seed. These seeds have a tuft of hair-like bristles that help them drift on the wind.
Canadian Rarity Status:
Not rare. Listed as “may be at risk” in Saskatchewan.
The hairy, mostly unbranched stems grow 15 – 70 cm tall. Leaves are alternate and narrowly spoon-shaped, becoming smaller and sparser up the stem. Each flowering heads (8-12 mm across) consists of 40 – 100 ray florets with rounded tips, and numerous 5-lobed disc florets – all with a tuft of short bristles. Narrow, hairy bracts occur in two to four rows behind each head. Fruits are achenes with hair-like bristles that help distribution of seeds by the wind.
