Erigeron calvus is a small biennial or perennial herb about 12 cm (5 inches) tall, producing a taproot. One plant can produce several flower heads, sometimes one per branch, sometimes in groups of 2 or 3. Each head has 50-100 small ray florets that are small and resemble disc florets, plus numerous genuine disc florets.Flora of North America, Erigeron calvus Coville, Bald daisy
