Ericameria resinosa, the Columbia goldenweed,[3] or Columbia goldenbush,[4] is a North American species of flowering shrubs in the family Asteraceae. It is native to the northwestern part of the United States, in the states of Washington, Oregon, and Idaho.[5][6]
Ericameria resinosa is a shrub up to 50 cm (20 inches) tall. It has leathery thread-like or narrowly oblanceolate leaves up to 25 mm (1 inch) long, with resinous glands on the surface. The flowers form at the tips of branches and are surrounded by a denser cluster of reduced leaves. Flower heads are white, with 10–15 disc florets and 0–7 ray florets.[7][8] Its habitats include rocky plains, steep hillsides, and rocky cliffs, usually rooted in rock crevices.[8]
