White-flowering Korean dandelion is a native to Korea and nearby northeastern Asia. Its white to very pale yellow flower heads stand out from the yellow dandelions familiar in U.S. lawns. It is not known to grow wild in the United States.
Common dandelion has bright yellow flower heads and its outer bracts bend sharply downward. White-flowering Korean dandelion has white to cream flowers and outer bracts that stay mostly upward.
Why they get mixed upBoth form low leaf rosettes, hollow flower stalks, and round seed heads.
