Rhaponticum repens (weed) (L.) Hidalgo - (Russian knapweed)

The native range is believed to extend from Turkey to China. It was accidentally introduced into North America around 1900 where it became an important weed in pastures and crops. It also invades various disturbed habitats and can form dense stands.

The plant establishes creeping patches up to a height of around 80 cm. It propagates mainly vegetatively through rhizomes, using allelopathic compounds to inhibit the growth of competing plants.
