Short Description
Riverside cocklebur can grow up to one metre high. It smells aromatic.
The leaves are broadly triangular to heart-shaped (cordiform).
The stem often has a red tinge.
It has male, small yellow and female, large green flower heads.
The fruiting flower heads completely enclose the ripe fruits. They are barbed, which creates a burdock effect.

Fun Facts
The flowering period is from August to October.
It is an annual plant, i.e. it flowers for only one summer and dies after the seeds have ripened.
- Endangerment level Germany: not evaluated
Riverside cocklebur has newly emerged in Europe from originally naturalised species from North America. It is thus a non-native plant (neophyte).
