Gamochaeta ustulata, commonly named featherweed or Pacific cudweed, [2] is a North American species of flowering plant in the family Asteraceae.

It is native to the western United States and southwestern Canada, in British Columbia, Washington, Oregon, and California.

It is found primarily on seaside hills and in the Coast Ranges, with additional populations inland.

Leaves are up to 5 cm (2.0 in) long, green on the top but appearing white on the underside because of many woolly hairs.

The plant forms many small flower heads in elongated arrays.
