Burdock pappus (Arctium spp) are a genus of leafy biennials that produce prickly burs. They are native to Europe and Asia, but have been introduced worldwide, where they are considered an invasive weed.

Burdock pappus develops clusters of purple flowers along the stem, that bloom from July to September. The seeds are contained in prickly burs.

The burs stick to the horse's body, which can cause skin irritation, and can cause damage to their eyes and inside their mouth.
