It grows in meadows, open forests, and along roadsides, and is about 45 cm tall. The stem is erect, stolonically branched, and densely bristled. The basal leaves are oblong to spatulate with entire, toothed or lobed margins and densely covered with wooly hairs. The cauline leaves are few and thin, and the white or pale lavender flower heads bloom from March to October. The central disk floret is yellow.
