Parasenecio hastatus
Also known as: Eastern groundsel
The parasenecio hastatus is a toxic flowering plant found growing wild in forests and grasslands throughout East Asia. It contains deadly alkaloids that are dangerous to mammals.

The parasenecio hastatus can become invasive when grown outside its native range.
