Introduced, yearlong-green, perennial herb, with a solid taproot and 30-50 cm tall. Leaves form a rosette and are bluntly lobed, 5-20 cm long and covered with bristly hairs. Flowerheads have solitary heads at the tips of solid, branched stems. Heads are 5-15 mm wide, with yellow ligulate flowers. Flowering is over most of the year. A native of Europe, it is common in pastures, along
roadsides and in disturbed areas. More common on low fertility, acid soils or where grazing promotes bare ground. Flat rosettes can cover a relatively large area and suppress more desirable plants. Selected by horses, but suspected (though never proven) that it can cause stringhalt in horses where it is dominant. Palatable and nutritious for cattle and sheep, but low growing habit restricts its availability. Best controlled with vigorous pastures as it is difficult and rarely economical to kill with herbicides. Strong pastures out-compete it as it is susceptible to shading and requires bare ground for germination. Fertilise to promote pastures and graze to produce shading and competition.
