Stolons are extensive, creating a dense mat of hawkweed plants that practically eliminates other vegetation. Stems are bristly and usually leafless, although occasionally a small leaf appears near the midpoint. Stems can reach a height of 3 feet and bear up to thirty inch flower heads near the top. Flowers are yellow and appear in late May or June. Stems and leaves exude milky juice when broken.
Seeds are black, tiny, and plumed .
No biological control agents are available for meadow hawkweed. Periodic application of selective herbicides applied to grass pastures in the early spring and followed by nitrogen fertilizer can keep the weed suppressed for 2 or more years.
