Goldenbush (Isocoma) is a genus of about fourteen species of flowering semi-woody shrubs from the sunflower family (Asteraceae) found mostly in the semi-arid areas of Southwestern United States and Mexico.
The name of this genus is derived from the Greek for "equal hair" refering to the pappus on the seed.
Isocoma species are used as food plants by the larvae of some Lepidoptera species including Schinia bicuspida (recorded on I. drummondii), Schinia erosa (feeds exclusively on I. acradenia) and Schinia tertia (recorded on I. pluriflora).
Species in the related genus Ericameria are also commonly known as Goldenbush.
