Helenium bolanderi is a species of flowering plant in the daisy family known by the common name coastal sneezeweed. It is native to the coastline of Oregon and northern California. This is a daisylike perennial herb varying in size from 20 centimeters to well over a meter in height. It has a generally unbranched, erect stem with oval-shaped leaves. The flowers arise on naked peduncles with one to three flower heads per inflorescence. Each flower head has a fringe of golden yellow ray florets reflexed away from a rounded center of disc florets in shades of yellow, red, or brown. The fruit is a tiny, hairy achene a few millimeters long.
