Bidens hyperborea (common names estuary beggarticks, [3] northern beggar-ticks [4] or estuary bur-marigold) [5] is a coastal species of flowering plant in the family Asteraceae. It grows along the coasts of Hudson Bay, the Arctic Ocean, and the North Atlantic Ocean in eastern Canada ( Labrador, [6] Nunavut, Ontario, Quebec, New Brunswick, Nova Scotia) and the northeastern United States ( Maine, New Hampshire, Massachusetts, New York). [7]
Bidens hyperborea is an annual herb up to 70 cm (28 inches) tall. It produces yellow flower heads sometimes one at a time, sometimes 2 or 3, each containing both disc florets and (usually) ray florets. The species grows in salt marshes and along the banks of marine estuaries. [8] [9]
