Squarrose knapweed prefers coarse, well drained soils on sites with cold winters and dry, hot summers. It is tolerant of alkaline soils and summer drought. Prevention: Seeds can be dispersed in soil, hay, animal hair/fur or by plants caught in vehicles.
Unlike Canada thistle for which it can be mistaken, Russian knapweed has no spines or prickles. Affected horses are unable to prehend and chew their food. Squarrose knapweed is a long-lived perennial with highly branched stems that grow one to three feet tall. The stems grow above a woody crown and stout taproot.
