Genus Eriophyllum is a group of plants that belongs to the sunflower family. Although there are limited synonyms for this genus, some commonly used ones include woolly sunflowers and tarweeds. The woolly sunflowers are named due to their hairy leaves that give them a woolly appearance. Tarweeds, on the other hand, come from the sticky resin that covers their leaves. These flowers are native to western North America and are often found in dry grasslands, chaparral, and forests. Eriophyllum species have been traditionally used for medicinal purposes, including treatment for coughs, colds, and fever. However, due to habitat loss, many of these species are now endangered.
