Krigia biflora, also known as two-flower cynthia or two-flower dwarf dandelion, is a North American species of plants in the sunflower family . It is native to central Canada (Manitoba and Ontario) and to the eastern, central, and southwestern United States.[2][3] Two-flowered Cynthia is rare in Connecticut, and it is listed as a species of special concern.[4]

Krigia biflora is an erect perennial growing 18 to 32 inches (450–800 mm) tall. One plant can have 20 or more flower heads, very often 2 per flower stalk, each head with 25-60 yellow to orange-yellow ray flowers about 1 to 1.5 inches (25–38 mm) across. There are no disc flowers. It can become an invasive plant. It grows in a variety of habitats and soils and blooms in late Spring to late Summer. The name of the plant consists of two words: Krigia for David Krieg, the German physician who first collected this plant in Maryland; and biflora, meaning two-flowered.[5][6]
