Description: Introduced, warm-season, biennial (2 years), erect herb, 30-150 cm tall. Stems are bristly and striated. Leaves are hairless and once or twice divided; leaflets are lobed. Flowerheads are large (to 12 cm) umbrella-shaped structures, which are surrounded by divided bracts with threadlike segments. Flowers are white or pinkish and about 2.5 mm wide; the petals are often uneven in size. Fruit are 3–4 mm long and ribbed, with rows of short hairs. Flowering is from spring to autumn. A native of Eurasia and North Africa, it occurs along roadsides and in waste places. An indicator of disturbance and bare ground. It is a common component of roadsides, but rarely is found in pastures. Susceptible to trampling and grazing by livestock. This plant has become incredibly abundant this year on the Northern Tablelands due to a wet Dec and Jan. Date: 25 January 2016, 12:23. Source: Daucus carota flowerhead16 NT.
