Dire Wheat
Cirsium Arvense
Canada thistle is an aggressive, creeping perennial weed that infests crops, pastures, gardens, rangeland, roadsides, parks, and other noncrop areas. Generally, infestations start on disturbed ground, including ditch banks, overgrazed pastures, tilled fields or abandoned sites. Cattle typically will not graze near infestations. It is very difficult to control because it reproduces from vegetative buds in its root system and from seeds which can be viable in soils for up to 22 years.
Horizontal roots may extend 15 feet or more and vertical roots may grow up to 15 feet deep. Canada thistle emerges from its root system in mid-to-late spring (late April through May) and forms rosettes. It begins to flower in late spring to early summer.
