Description:
A perennial weed from stolons that has a basal rosette of hairy leaves and yellow flowers that resemble dandelion. Mouseear hawkweed is primarily a weed of turfgrass, lawns, pastures, hayfields, and roadsides that is found throughout the northeastern United States and as far south as North Carolina.

• Control: Control of mouse-ear hawkweed is difficult because it usually grows in pastures where production levels are very low, and so it is difficult to economically justify spending too much per hectare to control it. Apart from this, selective herbicides give very poor control of it. To date, the best strategies have been to try out-competing it by increasing fertiliser inputs and trying to get pasture species growing strongly enough to smother the low-growing weed. A lot of work is being undertaken at present to find suitable biological control agents to attack the weed, with both disease and insect organisms being investigated.
