Korean Dandelion is an East Asian species rather than a U.S. native. Its yellow flower head sits alone on an unbranched stalk, followed by a round globe of wind-carried fruits.
Common dandelion (Taraxacum officinale) often has outer green bracts that bend downward. Korean Dandelion has outer bracts held close to the flower head, with small hornlike tips. Hybrids can blur this difference.
Why they get mixed upBoth have low leaf rosettes, yellow flower heads, and round white seed heads.
