Tar vine

Tar vine

This weed is found throughout Australia, with the exception of Tasmania. The origin of this species is unknown, but it may be native to the Kimberly, Pilbara and desert regions of Western Australia.

There are twelve species of Boerhavia in Australia, but B. coccinea is the most common in disturbed areas like agricultural fields or roadsides.

It is a common summer weed species, and like most summer weeds it depletes soil moisture and nutrients, reducing the yield potential of the subsequent crop.

This weed also acts as a green bridge for crop pests and disease, including scab disease, Melon viruses, Xylella fastidiosa disease of grapes and plague locusts. It can be a beneficial and highly palatable pasture species. Further updates are available here.
