Helenium puberulum is a species of flowering plant in the daisy family known by the common name rosilla. It is native to California and Baja California, where it can be found in moist habitats such as riverbanks and meadows. This is an annual or perennial herb varying in size and shape from a low stem with few branches to an erect, spindly stem nearing 1.5 meters tall. Most of the leaves are on the lower part of the plant, with the upper occupied by naked peduncles bearing inflorescences of several daisylike flower heads. Each head is mainly a spherical bunch of disc florets which are yellow when new and darken with age. Some heads also have a few to many yellow ray florets. The fruit is a hairy achene one to two millimeters long.
