Clematis koreana is a climbing vine native to northeastern Asian mountain woods. Its small, bell-shaped flowers hang downward, unlike the wide blooms of many garden clematis.
Both hang bell-like flowers. Alpine clematis is commonly blue to lavender, while typical C. koreana has narrower reddish-purple outer sepals; garden forms vary, so a flower photo alone may be uncertain.
Why they get mixed upBoth belong to the same early-flowering clematis group.
