In the Pacific Northwest, this is a non-native invasive introduced from Europe, found in disturbed sites. It shows up mid to late summer in fields, flower beds and between patio pavers. I find it easy to pull, it has a short tap root. Quite similar in form to C. setosa (bristly hawksbeard), but easy to tell the difference by looking at the stems. C. capillaris is quite smooth, whereas C. setosa has lots of little hairs.
