Heterotheca oregona is found in low-elevation mountain forests and chaparral, often near water. This is a perennial herb which is variable in appearance, with four somewhat indistinct varieties. It reaches a maximum height of 20 centimeters (8 inches) to one meter (40 inches), and is covered in small bristles. The inflorescence contains 1-15 flower heads in a flat-topped array. Each head has 14-60 yellowish disc florets but no ray florets. The fruit is an achene with a long grayish pappus.[5]
