Cudweeds are native herbs in the Asteraceae (daisy) family and comprise several closely related species that are winter annuals or short-lived perennials. They can be found growing on several continents.

The leaves are gray-green and covered in wooly hairs as is most of the plant. The flowers vary but are often in clusters of heads. in yellow, white or lavender. They grow 10 inches to 2 feet tall and are often found in sandy or rocky low-fertility soils in full sun. 

It is important as a butterfly host plant and has been used medicinally to treat parasites and sciatic pain. Some species may be appropriate in a naturalized area.
