Meadow Hawhfccd Comyki (Hieracium j^mtcme, H, fiorihindum, H. viloschiks) Category 2 Noxious Weed Meadow hawkweeds are perennial weeds with shallow, fibrous roots. Leaves are hairy, up to 6 inches long, spatula shaped, and almost exclusively basal. 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, 1/2 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. Meadow hawkweed was introduced into the United States from Europe. Spread is aided by contaminated grass seed. It is an extremely agressive weed that invades and domi- nates hay fields, meadows, pastures, riparian areas, rights-of-way and similar sites. It is found widely in northwestern Montana. Native hawkweeds differ from introduced hawkweeds because they lack stolons and have numerous upper stem leaves and a branched, open, flower Helpful identification tip: Narrow, spatula-shaped leaves are 4 to 6 inches long, dark green above, and light green beneath. 138.
