Eriastrum is a genus of flowering plants in the phlox family which are known commonly as woollystars. These wildflowers are somewhat diverse in appearance but are usually erect, thin-stemmed herbs which bear purple to white blooms. Most species have inflorescences which are webbed with a woolly mesh of white fibers. Woollystars are native to western North America.{{Cite web|title=Calflora: Plant Search|url=https://www.calflora.org//cgi-bin/specieslist.cgi?where-genus=Eriastrum|access-date=2020-07-10|website=www.calflora.org}}
