Senecio aronicoides

It is native to Oregon and northern and central California, where it can be found in the woodlands and forests of mountains and foothills, often in relatively dry habitat.

It is a biennial or perennial herb growing up to about 90 centimeters tall from a fleshy root attached to a buttonlike caudex.

The leaves have lance-shaped to oval blades measuring up to 20 centimeters long, the largest ones lower on the stem.

The flower heads are cups lined with black- or green-tipped phyllaries and filled with many gold disc florets.

The fruit is a hairless achene tipped with a pappus of long, white bristles.
